Cisco Switches :: Implementing VoIP With SG300-28P
Oct 12, 2012
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?
I was looking for configuring QOS for two VLANS i have created. these will be for voice traffic vlan 22 and video traffic vlan23. i also have three other vlans for pc's, wireless devices and our cnc machines. we have 5 switches that are all SG30028P's with a single switch doing the intervlan routing (operating at layer 3). all of the switches are trunked back to the main switch and ive been through the guide written on how to do this on a single switch which i dont think is layer 3.
try to configure QoS on a Cisco Small Business SG300 Switch. I followed the instruction on [URL] and configured one Port for tagging my Traffic from a Aastra IP Phone. Tagging works fine (i verified with wireshark).The problem is, that all traffic to a PC connected directly to the Aastra IP Phone is blocked. Is there a possibility to tag any other traffic to the port as a default?
I'm looking to configure the QOS for VOIP on my network.I have a switch SG300 and several no Cisco VOIP phone. What are the parameters to be taken to implement the QOS?
What is the procedure for installing the QOS? I need to create a VLAN for the data and one for VOIP?I read in the quick start guide that there is auto-QOS for VOIP?This can be done from the GUI? what are the options to put?
These are our first switches and seems like GUI is lot different than the online. Out intervlan routing is o not working. I am absolutely sure that I setup the switch in L3 mode since it allows me to create mutiple interfaces. I am hoping that this GUI issue is related to interVLAN routing.
Below is the blog I started for InterVlan issue [URL]
This is the link for online simulator and what I see in its IP tab. I know this switch is not SG300. [URL]
This is what I see on our switch.
Our switch version switchd64684#show version SW version 1.1.0.73 ( date 19-Jun-2011 time 18:10:49 ) Boot version 1.0.0.4 ( date 08-Apr-2010 time 16:37:57 ) HW version V01
I have SG300-28P that I am using as layer-3 switch. Recently I ran in to SG300-52 switch and even though loading same firmware doesn't give me option to do layer-3 switching. For SG-300 I see options in GUI to create vlan interfaces under IP information section, while SG300-52 has IP information option only under the management section.let me know if these are 2 different hardware types and L3 is not possible on SG300-52. If its possible to enable L3 switching on SG300-52?
I am implementing QoS on our MPLS network. Our environment exists of a mix of Cisco 2960 and 3560 switches. The IPT system is Avaya CM with Avaya phones.The WAN network is a MPLS network.Ports are configured for access and voice vlan (no trunking), one vlan for voice, one for data (vlan 1 is disabled).I dont have Qos coonfigured on LAN just wanted to configure on WAN Router where my Mpls link is connected.I have 45 Mb Mpls links on all sites connected to each other.
I have multiple sites connected via MPLS and i have control at both sides.Current config is mentioned below in which DSCP marking is not done for signaling. What is the best config with example.Current Config on all Cisco Router where MPLS link is terminated at all sites. [code]
I'm replacing 2 3COM 4500 Swithes with the SG300-52 Cisco switch. We have 3 VLANs, 10, 20, 100. The switch is set for Layer 3 and I have setup DHCP relay. what settings i should set on the Cisco for the following setups:
We have several of the SG300 Serices switches. We use them to route VLAN traffic to Remote Offices, Internet Connections, and WiFi Access Points.In one remote office we have a SG300-10 setup to route the HQ Network and the remote Office Subnet. The SG300 is Connected to HQ via Fiber and has multiple Tagged VLANs on it. If I do speed tests over the Fiber Link on the Incoming Tagged Netwotk I get Decent performance, 80Mbs. If I switch to a networtk that is not priginating from HQ, and have the SG300-10 route packet, I get dismal performance. 15-20Mbs.
I Fireded up a New SG300-28P FW v1.2.7.76. Added a the HQ VLAN 101 and new VLAN 1025 . Mapped some Tagged and untagged ports for each. Switch was connected to HQ Network as untagged VLAN 101. I put a laptop on an Untagged VLAN 101 port. Ran some tests, cam back with 750-850Mbs. Great. Put the same laptop on a Tagged 101 Port, Configured the NIC for Tagged VLAN 101, Same test, same Speeds, 750-850Mbs.I then Configured laptop for Tagged VLAN 1025. Connected to tagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!
I then Configured laptop for Untagged VLAN 1025. Connected to unagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!It was only the Laptop and the Connection to the HQ net on the SG300-28P. Why is the performance of this unit soooooo poor when it needs to route?Other Switches have FW v1.0.0.27 or FW v1.1.2.0. They have Similar speed issues. All Configured for Layer 3.
does the SG300 switches can be used with Microsoft NLB in Multicast mode?I know on traditional Catalyst switches you can statically "map" IP's to mac's and then to multiple ports but this doesn't seem to work correctly on the SG switches - it gives an error about the mac not being not Unicast?
Any snmpset commands to add, modify and delete vlan table entries on SG300-10 switches? I checked url... however this information is apparently only valid for catalysts. The latest firmware is installed and the provided MIB files are used.
I'm going to have several SG300-28P switches to setup. I'll need to create multiple vlans for data, voice, and wireless traffic. I have the following questions in setting up this configuration:
1) For managing the switches via IP, will LAN1 be the default management network? Should I create a seperate VLAN for managing the switches?
2) For uplinking the switches together, I plan to trunk a port to connect the switches together. What's the configuration on the trunk port to forward all vlans from one switch to another?
3) On some ports, I want to configure a trunk for two vlans (Data and Voice) where the phone has a pass through for PC. The phone supports tagging for the PC and the VoIP traffic. For example on port 10, would VLAN 100 and 300 be set to tagged?
I'm having alot of trouble trying to connect more that one LAG between two SG300-52 switches.Basically i have configured both switches with the same vlans. For 2 of the vlans i would like to connect them together between the two switches using LAG. Switch1 has Vlan 5 (ports 1-12) & Vlan 10 (Ports 25-36) with LAG configured on ports 1-2 and ports 25-26. I have setup the second switch identical to the first. But when i connect the LAG's there is no connectivty. If i disconnect one LAG the other starts working.Can you only have i interconnect LAG between switches?
I have two SG300 serie switches and two Gigabit connection between them. How do I configured these two links to work toghether like a one 2 Gigabit channel?
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 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.
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 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.?
how to configure QoS on my SGE2010 to support my Toshiba CIX PBX VoIP trunks. The infrastructure is straight forward: PBX(1)<==>SGE2010(1)<==>SGE2010(2)<==>SGE2010(3)<==>PBX(2) where PBX(1) and PBX(2) are connected through three SGE2010's that are trunked via fiber between buildings. I don't have VoIP handsets and the PBX's are on their own VLAN. Everything else has been a breeze in these switches but I have no experience with QoS
I'm going to move offices into a shared situation with 3 companies. Each company will want its own private network so there's no snooping between companies. I am planning on using VOIP for the phone system (Nextiva cloud based). Is it possible to set up the system so that each company has access to the VOIP system but yet remains sequestered in the their own network for everything else. I was hoping to do this with one data port at each workstation using Cisco SPA-303 phones. The way I understand this, is that the phone plugs in to the data port and you daisy chain the workstation off from each phone. Is this possible to do this while having the system I described? Another wrinkle is that I'd also like all the networks to be access shared printers.
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 have a question, does the SG300-28 support VTP and STP?. I want to add it to my network's VTP domain so I don't have to manage vlans manually on the SG300-28 and also be able to configure STP to keep my network loop free.
I need to know how to configure each port in switch SG300-10 to vlans, i need to configure one port "trunk" with catalyst switch and assign 4 ports to different vlans. any solution?
