Cisco Switches :: Sge2010p (v5) - How To Set QoS For VoIP Vlan
Jul 24, 2011
I have configured 2 Vlans on the network. 1 - native Untagged for data traffic and 100 Tagged for VoIP.I have 4 SGE2010p switches 2- of them in stack working in L3 mode and 2 connected to the stack via single ethernet links in L2 mode.I have IP phones with trunked ports -Vlan100 tagged and 1 untagged. I have set CoS 5 for Voice Vlan 100 on the phones and CoS 5 to queue 3 mapping (in basic mode) on all switches.But it seems to not work at all.Should I use Advanced QoS mode?Where Can I find some QoS configuration example for Voice Vlan on SGE2010p switches?
I just purchased two Cisco switches (SGE2010P) for the new Mitel 5000 Phone System. The Mitel vendor programmed and setup the phone system for us, but they couldn’t figure out the VLAN setup on the my switch. So now I have everything on one network and I am stuck on my own to figure the VLAN on my own. So please, some step by step on the settings on the switches, the router and the server (DHCP).
Here is what I have now: 2 floors building with a Cisco SGE2010P switch for each floor.Sonicwall TZ 210 routerWindows 2008 R2 server for DHCPMitel 5000I have the switch on Layer 2 at this moment, but I can switch it to Layer 3 if that makes the process easier and less steps.My network as follows: Router: 192.168.123.254Windows Server: 192.168.123.9Switches: 192.168.123.5 and 192.168.123.6Mitel 5000 server: 192.168.123.7 (has to be changed)The PCs are connected to the phones.
I am new to VLANs and Cisco SMB switches. I have a new SGE 2010P switch and i am trying to configure different VLANs, one for data, one for Voice and the other for server.
Is there any tutorial on how to configure VLAN, by the way i tried to used the web interface and admin guide, it totally confused my understanding of Vlans.
Just got a new SGE2010P layer 3 switch. I'm trying to configure Vlan to reach a few subnet. I have the original 192.168.1.0/24 as vlan1. I want to reach our WiFi subnet 192.168.10.0/24. The WIFI router is directly connected. It's new for me as the previous Job i was sorking with a ws-3750-48.
i did from console change my switch to layer 3 mode... ( i want it as the DGW for each Vlan)from the web interface, i create a vlan4 for our WIFI Next i go to ipv4 to add an IP address to vlan 4 like 192.168.10.254 /24 As soon as I apply the IP the switch stop responding, Ping request time out.. i need to reboot the switch..
We are upgrading out internal office network. I have setup 4 switches and 1 router using the following config.
-2 SGE2010p's are stacked together forming vlan 30 (to be used for phones)
-2 SGE2010's stacked for workstation's under vlan 20
Both switches are apart of vlan 1 (the default)Ports 1 on each stack are connected to a Cisco 890 (port fe2 and fe3) in trunk mode. Ports 2 and 3 are in an LAG group and connected to the neighboring stack (I have attached a diagram), and are also in trunk mode).At this point one port (port 1 on either stack) goes into blocking mode, and I get why ,it's a physical loop.I need more than a 100mb link between switches (which is what pulling the LAG between switches gets me), but I don't want to route phone traffic through my workstation switches to get out of the LAN.Is it possible using these switches and router to have a LAG between stacks and a link to the router for traffic to 0.0.0.0 ?
I am new to VLANs although I generally understand the concept. I have a small office with 25 desktop/laptops and 15 VoIP phones connected with a SG200-50 switch and on Port 1 I have the Cisco SRP541W router for DHCP and Internet access. My goal is simple: 1) Segregate the VoIP phones (voice) from the computers (data) and 2) Prioritize the VoIP phones traffic.
I believe this can be accomplished by setting up a second VLAN and maybe a third (if the default should not be used) and then identifying those ports as Voice VLAN ports. I guess I just need to know how to flag each interface and each port so that they all can talk to the router on Port 1 yet the voice and data will be in different broadcast domains. Also, do I need a management VLAN??
Is this setup correct? VLAN 1 - default (data) Port 1 (Trunk) (Tagged)Port 2 - 30 (Access) (Untagged)VLAN 2 - voice Port 1 (Trunk) (Tagged)Port 31 - 48 (Access) (Untagged) What should the interface settings be on each port (General, Access or Trunk)? What should the port VLAN membership be on each port (Tagged or Untagged)??
I'm the administrator of a system composed of seven SGE2010P switches in stack configuration.I developed a script to update the ACL at regular time intervals.
ACLs work well unless one or more switches in the stack is turned off. In this case it would seem that once, which switches off will restart, they do not synchronize ACLs assigned to interfaces.
Currently the only solution I've found to restore functionality, it is cold restart of the entire stack.I was wondering if there is a command to propagate the acl switches that I can recall in the event of a restart of any of these.
I have created two vlans, vlan 1 data and vlan 200 voice. the issue is that when an on one vlan i cannot ping the default gateway of the othe vlan from my PC. An using sge 2010p switches.
below is my configuration p route 0.0.0.0 0.0.0.0 192.168.0.1 ip dhcp relay address 192.168.0.100 ip dhcp relay enable ip dhcp information option interface vlan 1 ip dhcp relay enable(code )
I recently changed jobs and am now supporting a small(but rapidly growing) environment as follows:
35 PoE phones with a switchport going to a workstation 8 PoE cameras 7 servers(2 NICs each with link aggregation) Various racked network hardware
I currently have an Enterasys 10/100 48p PoE switch powering all of the PoE devices, but the switch is getting old and I'd like to start converting over to pure gigabit. There's also an HP Procurve 2810-48G that all of the servers and other racked network hardware are plugged into. That switch is fine, but doesn't have PoE, so its uses are limited to the rack.
Just a few other things to keep in mind... Whomever setup this network failed to separate the voice and data traffic into their own VLANs + QoS, so that needs to be done as well. Expandability is key as the company is growing at a rapid pace- Stacking is certainly desirable, but not an absolute requirement.
I'd like to keep the price point bellow $2000 if I can get a good product. Cisco would be cool, but the price point is way too high for the features that I need. Any great recommendations? Here's some that I've been looking at:
I have a Cisco Calayst C3560G core switch with 4 x SGE2010P Switches which are invidually linked/trunked via 2x CAT6 Cables for each SGE switch so im not stacking them. First problem is i cant seem to trunk/bond the 2 cables to the SGE LAGs i created, I can only use 1 cable per SGE switch. Yes the Core switch is configured correctly and have the proper Port Channel config (below is an example of a config) how do i get this working!?
I run POE Voip phones and PC's of 1 cable that is vlan'd on the phones, so each port on the SGE's are trunk'd
The other issue and more troublesome is that I have random reboots on all of the SGE's the LOGs tell me nothing! I cant seem to figure it out even had the units swapped out! Jumbo Frames are enabled but still happens even if disabled. Got some STP/RSTP settings but nothing works.
SGE Hardware Version 00.00.01 SGE Software Version 3.0.018 SGE Boot Version 2.0.0.03
I have configured stack with 2 sge2010p switches. I want to connect this stack to the HP procurve switch using port agregation (LAG) technique. I want to use one ge port on each sge switch.How to configure it? Will it work witch port agregation on procurve?
Originally I was happy just set them all up in a stacked ring configuration. However I've become aware that my back bone fibre links are contantly pushed to their max.
So I've decided that I should change this configuration and unstack the switches and make them all stand-alone units. and I'll configure 2 cable LAG links between all my switches Theorically I should now get 2GIGs between each switch and to complete the ring in my network for redundancy I'll turn on Spanning tree.
However I've tested the speed and I just can not seem to get a LAG connection with 2 x 1gig cables to push more data than a single link 1gig link cable would.
My test enviroment(not using fibre optic cables just cat5e copper cabling): 4 x pc's(all gigabit network cards) 2 x sge2000p switches PC1 ---(1G eth)--- /---(1G eth)--- PC2 [SGE2000P]===(LAG1 2x1G cables)===[SGE2000P] PC3 ---(1G eth)---/ ---(1G eth)--- PC4
If I send files from PC1 & PC3 simultaneously to PC2 & PC4 They don't transfer faster than if I I just use a single 1GIG Link cable
looking at the LAG configuration it shows both cables are connected & the LAG looks like it's working. But it really doesn't seem to be running at the expected 2GIG?
The LAG fail over seems to work fine if I remove either of the 2 cables from the LAG the link continues to work. (sometimes it will drop a ping when removing or readding a LAG cable)
I have switche SGE2010P, router 871 and 3 cisco ip phone 7920. If cisco ip phone 7920 connected to switche SGE2010P then link is down. But if cisco ip phone 7920 connected to router 871 then link is up. In the log switche SGE2010P is not event about this.Why are cisco ip phone 7920 not work with switche SGE2010P?
When I try to apply an ACL to a port on my SGE2010P, I get the following error:Can't bind acl/policy-map to an interface when the security suite is enabled in a per-port mode.I don't see an option where I can set the security suite mode.
I have just downloaded new software for sge2010p. I had tried to made an upgrade on some switches, but switches still boot with the old software.I have installed software 3.0.0.18 and boot 2.0.0.03. I have downloaded software 3.0.1 from cisco, put it on tftp and started an upgrade via switch web interface. I have checked that the active image is set to 1, and started the upgrade.Switch has downloaded soft from tftp, and reported that process has been finished without errors.After the restart switch have 3.0.0.18 software again. I have try to do this same on 4 different switches working in L3 and L2 mode - always with the same effect.Should I upgrade both images in the same time to get this work?
I have noticed, that the new firmware is located on image 2.
# show bootvar Image Filename Version Date Status ----- --------- --------- --------------------- ----------- 1 image-1 3.0.0.18 08-Nov-2009 16:21:37 Active 2 image-2 3.0.1.0 19-May-2011 13:05:53 Not active* [Code] ...
So I try to set active image via console command: # boot system image-2
and again... a# show bootvar Image Filename Version Date Status ----- --------- --------- --------------------- ----------- 1 image-1 3.0.0.18 08-Nov-2009 16:21:37 Active* 2 image-2 3.0.1.0 19-May-2011 13:05:53 Not active
"*" designates that the image was selected for the next boot
Finally i have tried to set the active image to "2" using console menu: I have set it like this:
Active Image ============
Unit ID Active Image Active Image after Reset ======= ============ ======================== 1 Image 1 Image 2
and save.. [Code]
Where is the right place to set active image for 2. Is the "active image" settings only sets the firmware image which switch uses or configuration files too?
Recently our company purchased 3 Lynksys SGE2010p, At the moment they work as a stack but as we are implementing UCCX we need to mirror 15 ports but during the provisioning i've noticed that the limit is 8 ports per stack. I'm wondering whether this is a known issue or just a known limitation . I believe that most probably i'll need to move back to stand alone mode so i could configure 8 mirrored ports per switch.
Created 2 separate VLANs on SGE2010P switch. Neither in Native VLAN 1.
For example;
-Port g01 in VLAN 56 -Port g25 in VLAN 56 -Port g10 in VLAN 10 -Port g37 in VLAN 10
All appears to work well within the respective VLAN (i.e. DHCP, ARP, etc. no IPs from other VLANs)STP - Spanning Tree is Globally disabled.
However; when I feed a n new network (which has STP enabled) into VLAN 10; I then plug a laptop with wireshark running into VLAN 56 - cannot see any other traffic/packet...except STP packets coming from a CISCO device on VLAN 10 while I am plugged into VLAN 56.
This demonstrates to me the network is not truely seperated. I know this because last night I crossed two networks and caused havoc; ouch.I configed a D-Link switch with the same scenario and no issue.
I just inherited a network and feel like.I am missing something. We use ATT&T Opt-E-Man which limits the MAC address to 50 for the connection or you have to pay.Hence the routing VLAN is the only access across the two sites.I have a VoIP vendor who insists on using the same VLAN for all sites. Upon exam the VLAN is at the remote site but it does not work.
I am trying to get QoS for my VoIP system setup on several SGE2000p switches and have got a question...How do I define the ACL for RTP? As far as I can tell it will not let me enter a UDP port range for the RTP traffic... And I cant imagine creating rules for each port would be very effective either. So, how can I define an ACL to cover the RTP traffic so I can classify it?
I want to implement VoIP on my client network, currently the data network is using SG300-28P small business switches for user access. According to my design the IP Phones (Cisco 9971 and 7942G IP Phones) are to connect to the small business access switches while the user PCs connects to the IP Phones.
My concern is I really don't understand how the small busness switches will advertise the voice VLAN to the IP Phones. I understand that the switches are suppouse to use LLDP/CDP for this but it seems the model I have can only do LLDP. The IP Phones and the PCs connected to them will be recieving IP addresses from an uplink L3 managed switch.
how LLDP works (particularly regarding this scenario)? Does it matter if the small business switch is in L2 or L3 mode for the VoIP implementation?
We are trying to config vlan 10 for data and vlan 20 for voice on the same port - port 1 of swtich SF300-24P to run both data and voice on different vlans.Do I have to add vlan 10 as an untagged vlan to port 1 and add vlan 20 as an tagged vlan to port 1?If I do not want to assign the native vlan 1 to port 1, how can I remove it ? The GUI page - assign VLAN to port does not allow to remove it.Aslo, what mode shall I set up on port 1? General, trunk or access ?
We have a Cisco slm248gt-na smart switch in our office that I am trying to configure to support and optimize for VoIP. We have desktops hooked up off the phones in most cases. Are there any config guidelines to optimize the switch so it has proper QOS set and VoIP gets higher priority over data.
I am looking for a Best Practices or a few places to pay attention to in the Cisco ESW-520-48P switch I have. My VoIP solution is RingCentral, and while they are Cisco phones, I've been hestitant to setup VLANs etc. the way I am used to. Plus setting up Auto QoS seems different than what I am used to with a 3750 switch.
Right now I've left the Smartports Wizard alone, and none of the ports are configured. There are no VLANs or QoS on the LAN currently.
What I was running into were calls cutting out where one side wouldn't hear the other anymore, but the call would remain connected. However, this has happened in this small 15 person office, when there is only one employee here after hours, talking on the phone. There isn't any heavy network traffic, because I have network monitoring showing me low usage (no streaming music, videos, or anything else).
This switch has a Gb connection to a Linksys SR2024 (the server switch), which is also set at Factory Defaults. I mention that because I recently bypassed the ESW-520-48P, and plugged one phone into that switch and the RingCentral phone worked fine for outside calls.
Is there something besides QoS that I should look at in the ESW-520 switch that might be causing a checkpoint of some sort, or interrupting VoIP traffic that I need to configure or disable?
And are there any Best Practices or scenario guides for this switch? I found the Admin Guide, but it really just explains every option in the GUI for the switch. And it seems all of my CCNA training isn't working with going in and quickly troubleshooting this switch besides knowing that something in it could be hanging it up.
We have a VOIP system with 1 physical NIC attached to our SG500X. It has a virtual MAC address along with the physical MAC address. It has 2 IP addresses tied to it.
I can ping the physical IP address, but can only ping the virtual address from the same vlan as the virtual nic. However, if I clear the arp table, a few pings will go through until they all time out again. This is causing problems on my phone system, and I need to establish this communication. I have tried putting in static MAC and ARP entries, but that does not work.
We have a customer running a Asterisk based Phone system, using Snom 320 phones and a ESW-520-24P as their switch.
Recently we have been confronted with an issue where every 35 seconds their is a very obvious drop of audio for both parties of a call. We know it is not the phone system as we have run tests directly over the BT copper lines that have no drops what so ever. Unfrotunately when we introduce the LAN in any way, we get the drops every 35 seconds.
We are running the whole solution on 1 vlan, yes I know probably better to use two, but the Cisco cannot automatically detect the Snom 320 phones to swap it to another VLAN, which complicates using a VLAN setup.
I really need to work out how to stop these packet drops, but I am new to the world of Cisco and dont really know where to look or what to try.
I have a Netgear GSM7248R switch with 5 different Vlans including th management Vlan. Each of the vlans are connected to my layer 3 switch for routing. I want to access the management vlan form any of my Vlans so my layer two switch can be detected by my snmp manager.
I have VOIP and was provided a modem, a Tilgen Router (Vood 452_A). I also currently have a Linksys WRT54G router. I also have a home surveillance system with a DVR that can be accessed via the net. I am trying to allow the ports to open so that traffic can navigate down to the DVR.My IPs:My VOIP has provided me with 6 static IP addresses. For sake of this issue they are:
67.xx.xxx.153, through .158My subnetmask is set to:
255.255.255.248My Settings:
The Modem is connected to world. To the modem I have the Tilgen Router connected. The Tilgen is set with an ip of .153 and the subnetmask listed above. DHCP is turned on and has IP range set for .154-.158. It is set in Bridge Mode with NAT and Firewall turned off. To that I have the WRTG54G router connected and assigned the router an Static IP of .154.. The cable is going into the Linksys WAN port.From a computer connected to a LAN port on the WRT54G, I see my public IP as .154, currently my internal IP is 192.168.1.15 so I believe I have to assign one of my Static IPs to this PC, however when I try to connect to the Linksys Router (.154) from the outside web, I am get a time out error. (also from a ping test.) My thoughts are to assign the Linksys to DHCP and use a range of .155-.158 to give each lan item a static IP. My question is will this work? Will each item in the network have its own IP and if I forward the port to the DVR that i needed, ie 80 for web client or 6100 for desktop client, will that forward through?Or do I set it to Router Mode and use the Tilgen to assign the ips.
On the Tilgen I also have an option for a DHCP relay or to turn off DHCP.
For clarification here is the setup chain Broadband/DSL Line>>Tilgen Modem>>(LANPort1)Tilgen Router(LAN Port2)>>(WAN) Linksys(LANPort1)>>DVR/Computers Found this walkthrough on setting the WRT54G into a Switch. If I did this, in theory the VOOD would assign those computers/dvr connected downstream via the WRT54G a static ip from my range set on the router. Then in theory I would not need to port forward port 80 since the DVR would be on its own public IP.?
I have some problem in my small network.I have 2 SF-300 48 port switches and connected to 847 router for intervlan routing. I configure 7 vlan in SW1 and uplink to SW2 with trunkport.
The problem is that if i used default gateway for users ip address of interface (vlan interface) is ok. I bring two adsl modem and connected to vlan1 and vlan2 for internet access. When i connected this two modem vlan 1 and vlan 2 are not going to access other vlan 3,4,5,6,7 and wise versa.
vlan1 users getting default gateway from adsl modem ip, how i can permit this two vlan should to access other vlan 3,4,5,6,7 and 3,4,5,6,7 should access to internet also.
