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 just purchased a new SF-300 managed switch for the purpose of using it on the DMZ, so we can mirror the internet port and monitor traffic for my company. I have set it up from the web interface to miror port 1 to port 2 and that's pretty much it. I decided to test it before putting it in production, by hooking it up to one of my core network switches, connecting a laptop to it and trying to get online. It doesn't even connect to my DHCP server to get an IP address. If I put the laptop back on the same subnet as the switch management IP, I can still connect to the switches web interface. Isn't the basic functionality of a switch to pass traffic?
I should also mention that I'm not a network engineer, so there might just be something I'm missing with regard to a default setting that needs to be switched off?
I am migrating an a group of workstations that run a fire system from one software to another. The current workstations run the following info:123.123.123.xxx 255.255.255.0The new workstations run:100.100.100.xxx 255.255.255.0There is a central switch location using a GE-DSG-244 Layer 2+ Managed switch. There are two remote location using GE-DS-82 Managed Switches.The two networks must remain isolated, yet use the same fiber communications. The central switch connects to the two location using MM Fiber. From my research I believe I need to use the 802.1q standard to allow port trunking between the two switches.

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?
View 4 Replies View RelatedI 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 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?

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:

recommendation for a PoE-compliant (802.3af) 10/100 ethernet switch suited for the following use. A client wants a separate [from their data] network dedicated to their new IP CCTV/IP Intercomm system (Stentofon ISO5 Cleanroom Certified). Total of 15 devices, all of which support PoE, 11 of which require it. The intercomm system will be the primary method of communication with personnel inside the clean space, so it must have minimum downtime.
1) 16x RJ45 (Only 15 devices -- anything over 16 ports is waste, SFP/expansion/combo ports not required)
2) *All* ports 802.3af PoE compliant, approx 5W load.
3) 10/100 (Gigabit not necessary, there's only 2 cameras and voice traffic is compressed)
4) Prefer rackmount but not necessary
5) Prefer Cisco/Cisco SB simply because I trust 'em (have an IAD and switch going strong for years with no downtime )
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.
I have a SF300 24 P and Iam trying to configure a voice vlan this is what I have done so far and it doesnt work.
1. create vlan 30 for voice traffic and enable it
2. Telephony OUI add my mac address for allworx phones
3. Port to VLAN add 30 has tagged, port to vlan 1 untagged
4. Vlan to port I try to add 30 and get this error (Port e15 is candidate in voice Vlan 30 and cant be configured as static member in the vlan.
5. Under Discovery LLDP, LLDP MED port Setting Enable MED status, then all other options to yes
In my LLDP neighbor information all my phones are there and says under port ID 0 ( my phones support LLDP and CDP)
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 6 cisco switches already on my network and I just got a 2960S PoE switch that I need to enable for VoIP. The voice vendor is coming in to setup our phone system for VoIP and I need to enable this new 2960S 48 port switch for the VoIP phones, I don't know how to do that, or other taskes needed for this project.
I was told that I need to uplink the new 2960S with the Catalysy 4507R using an ethernet cable and to "trunk the ports" and enable the 2960S as a VTP client - ok great - how?
I was told I also need to use the switch port voice VLAN command for the new VLAN - again, great - but how?
I actually was able to telnet into the switch and I gave it an IP and I created a new vlan but thats all. We are using non Cisco IP phones.
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.
View 7 Replies View RelatedI 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 Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
I'm using two sg 300 switch (Fw 1.1.1.8) and I configured vlans for data and phone. Enabling voice lan, dynamic voice vlan, the option Enable Thelephon OUI is grayed.I think that this is related to LLDP and CDP setting's, but I'm not able to discovery how.How to enable thelephon OUI?

View 1 Replies View RelatedI'm asked to think of a solution to make in an existing LAN connected by switches (connected to each other) to make another network availible.atm we have a network with 192.168.110.0 and we are short on IP adresses because of a large DHCP pool from wireless clients and a growing network with static IP addresses.So basicly what i want to accomplish is an extra network 192.168.111.0 in the existing LAN and all computers have to be able to communicate to each other and all computers have to be able to connect to the internet using gateway 192.168.110.1 (direct or trough route tables). For future growth an extra LAN 192.168.112.0 with not perse internet access for only VOIP, but that is on the side and is not a priority, because I can set up that network on the same switches easy without having them to be able to connect to the computers and servers in the network. (correct me if I am wrong)
What I found out browsing the internet is that a layer 3 switch may provide the solution, but I can't make out of the technical specs if thats going to work when both LAN's computers will be connected on the same switches.Also I found a lot of solutions with setting up a server with 2 NIC's and setting up routes on that server. But since we have a very large amount of network traffic with large graphical files, having 2 nics to route all that trafic doesn't seem like a desirable solution for my purpose.
i want to setup IGMP Snooping on the Managed Switch SG 300-10. I do it over the webinterface. Enable Bride Multicast Filtering, Forwarding Method IP Group Address and enable IGMP Snooping v3. In the local Network i stream up to 4 Multicast streams 239.1.1.1-239.1.1.4. The client vor the Multicast are IP setupboxes. If i connect PRTG Network Monitor over SNMP to see the Traffic on the ports i see that all Multicast streams are at every port. What is the false i do? I thought only the multicast stream that is shoosen at the client are forwarding and not all multicast streams. The IP STBs have only a 100Mbit network adapter and i have to muticast over 10 Streams (10Mbit per stream) over the local VLAN. So i think IGMP Snooping is the solution for me. Or need i also a Multicast router?

I know it isn't the easiest configuration and I need to set this up without purchasing any more equipment if at all possible.I have a Cisco SG 300-28 setup with three VLAN's. [code] Default Gateway is 192.168.10.1 (Netgear Router)I have a Wireless network setup (Netgear WMS and 2 WAP's) configured with the TWO VLAN's (1 and 3). These go into ports on the Cisco SG 300-28 which are tagged on both VLAN's. The Business wireless worked fine but the guest network didn't reout out to the internet.After some troubleshooting I realised the reason the guest wasn't working was because there was no route back from the internet to the router.
The router I have isn't really ideal, it is a Netgear DGN2200, but I managed to create a static route to 192.168.30.1 with a metric of 2, with 192,168,10.254 being the hop. Success, the connection worked, the only problem is that now my guest network can see my business network because the business network is using the static route on my router to route back over to the guest network (due to the limitations of this device I can't do anything about that)Guest network can connect to Business VLAN via switch. I am assuming this is because the router is on the Business VLAN and the default gateway is the router. As they are on the same network the Guest network can inevetably see the business server and network.The Business network can get back to the Guest network via the router using my static route I created. The static route is really basic and I can't create a firewall rule on the router to prevent the Business network speaking to guest network because it only has a LAN - WAN firewall and this connection is LAN - LAN.
What I need is...to somehow stop any traffic from the 192.168.30.0 network routing to anything on the 192.168.10.0 network, appart from the router on 192.168.10.1.Is this possible? I have this setup on a number of different site, the only difference is I have a CIsco Security Router on these with the VLAN's configured so I don't have this problem. Because I have a rather limited Netgear DGN2200 I am unable to setup the VLAN's correctly and as such I need to see if I can do this on the switch in any way.
