Voice-vlan problem in DID

Dear sir
i wanted to know that how can i hear voice in my voice vlan. as i m using 2801 voice gateway with PRI (only PSTN connectivity) ,and 3560 switch for voice and data vlan.
My voice gateway IP is 192.168.1.221 and is data Vlan on port 7 as mentioned in attched file.
similarly call manager is also on data vlan and on port 24. and my call manager ip is 192.168.1.54.
my ip phones are in port 3 and port 4 and using static ip address no DHCP server.
Ip phone address are 192.168.2.113 and 192.168.2.118 9 both are in voice vlan)
My problem is when external caller calls on my DID numbers call rings and any external user can easily hear voice, but my internal user is unable to hear any voice of external caller.
this behavior works fine without any data/voice vlan configuration.
i am confuse this shows me a problem with vlan only.
kindly correct me your assistance will be higly appreciated.
thanks

Zeeshan,
Thanks for posting the gateway configuration. You've stated that the problem is that when a call comes in from the PSTN, the internal user is unable to hear the audio of the external caller, while the external caller can hear the internal caller.
The reason is because the gateway does not have a route to the subnet that the internal phones are in. To fix he problem, add the following route in the gateway so that the audio of the external caller may be routed correctly to the phone subnet:
ip route 192.168.2.0 255.255.255.0 192.168.1.1
Test after making the change and let us know if you still have the issue.
Hope this helps.
Michael.

SG300 voice vlan problem with UC520

Hi Forumers'
My problem statement:
- refere to attached topology.png, this is how my network structure look like
- the IP phone after boot cannot get connected, so it can't download the XML config file from UC520. suspicious switching problem.
- my configuration shown at topology.png and my vlan voice config show as voice vlan setting.png
- My requirement is SG300 switch single switchport to carry vlan data and vlan voice.
- what is the trunking mode for voice VLAN siwth a IP phone+data should i configure? is it switchport voice vlan vvid, switchport voice vlan dot1p, switchport voice vlan untagged or switchport voice vlan none to suite above requirement?
thanks
Noel

Hello Noel,
Sorry for the late reply, things have been quite hectic around here lately
1. Why use trunk? the UC520 only have vlan voice (vlan 20)
Do you mean that the data VLAN is handled by another device ? Still I would leave it as a trunk in order to be able manage the UC through the data VLAN. (Unless for security or other reasons you would choose otherwise of course)
2. The UC520 got CUE (voice messaging), how should i design the service module uplink to the core switch?
Nothing in particular has to be done for this, CUE is handled and routed inside the UC520, the CUE vlan (default ID =90) is only used if you have another CUE in the network
1. i guess i did this: swithcport tagged vlan 20, untagged vlan 10. is it ok for this setting?
If the Voice Vlan on the switch and on the UC520 has been defined as VLAN 20 (default = VLAN 100) this is perfect. Verify if both on the UC and on the switch, the voice VLAN ID is set to 20.
1. so if i just point the phone to vlan 20 (vlan voice), should i create the LLDP network policy?
If you are ready to configure the VLAN manually on the phone, you don't need the LLDP policy, that is correct.
The LLDP policy is being used for having the phones automatically choose the VLAN you defined, so you don't need to set it manually.
Hope this answers your questions ?

SRW224G4P : voice vlan problem

Hi guys ,
i've a problem with tagged vlan with my SRW224G4P.
I,ve got following scenario:
one cisco 2801-CCME/k9 router
one cisco small business SRW224G4P layer 2 managed switch
ten cisco IP phone 7940 and 7931
ten personal computer
I need to use the embedded switch on the phone to connect computer . I need to
have 2 separated vlan for data and voice traffic.
I configured srw224g4p first 12 ports as follows
interface ethernet 1/x
switchport allowed vlan add 199 untagged
switchport native vlan 199
switchport allowed vlan remove 1
switchport mode hybrid
switchport allowed vlan add 150 tagged
spanning-tree cost 100000
spanning-tree edge-port
where vlan 199 is for data and vlan 150 is for voice .
I set following dhcp pool on 2801
ip dhcp pool phones
network 192.168.150.0 255.255.255.0
default-router 192.168.150.1
domain-name cmedeis.local
option 150 ip 192.168.150.1
ip dhcp pool PC
network 192.168.199.0 255.255.255.0
default-router 1982.168.199.1
and configured router on a stick as follows
interface FastEthernet0/0.150
description CME interface
encapsulation dot1Q 150
ip address 192.168.150.1 255.255.255.0
interface FastEthernet0/0.199
encapsulation dot1Q 199
ip address 192.168.199.1 255.255.255.0
My problem is that phones connected to the switch ports doesn't recognize tagged
traffic and doesn't take ip of the corrected dhcp pool of 150 vlan.
With a cisco 2960 poe switch i configured switchport voice vlan 150 and
switchport access vlan 199 and all is fine but this small business switch don't
handle switchport voice attribute and i can't separate voice and data vlan .
Someone have idea how to avoid this problem?
Need some help , please.
Bye

Good posts as always Christopher!
As Christopher mentions you will need to hard code the voice vlan on all of the phones. The phones will send the voice traffic via this vlan, and the PCs will send untagged traffic.
I hope you do not mind a tangent and I hope this is not too great of a distraction, but the thought of QoS and security came to my mind as I read this post.
Besides the vlan problems, which I am sure we can get through, there is also a concern.
Any chance you would consider a 3560 for this deployment? You have quite a few Cisco phones, a Cisco router, and many PCs. The Cisco switch would give you CDP, which would be useful for the voice vlan and power settings, as well as the important automatic QoS and security settings.
On my 3560, I applied a smart port macro. A smart port macro is a series of best practices / command sets put into a simple to use command. The one I applied is called cisco-phone. Here is the output before and after:
c3560(config)#do sho run int f0/18
interface FastEthernet0/18
end
c3560(config)#int f0/18
c3560(config-if)#macr app cisco-phone
c3560(config-if)#sw voice vlan 5
c3560(config-if)#sw ac vl 1
c3560(config-if)#do sho run int f0/18
interface FastEthernet0/18
switchport mode access
switchport voice vlan 5
switchport port-security maximum 2
switchport port-security
switchport port-security aging time 2
switchport port-security violation restrict
switchport port-security aging type inactivity
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
mls qos trust device cisco-phone
mls qos trust cos
macro description cisco-phone
auto qos voip cisco-phone
spanning-tree portfast
spanning-tree bpduguard enable
end
The switch automatically globally enabled mls qos and configured the many class-maps, policy-maps, and applied them all accordingly. As you know, it is important to establish the trust boundaries when doing voice and QoS. These switches also uses SRR which is a very good way of applying shaping.
Does this help? I hope so. Please fire back any thoughts or questions you may have.

SG-300 28P switches problem with VLAN Data and Voice, working all the time as Voice VLAN

Hi Everyone,
Thank you very much for your help in advance. I’m pulling my hair to fix the problem.
I just got the new SG-300 28P switches. My Bios ordered for me. I did not know how it runs until now... not an IOS based. I really do not know how to configure it.
I have 2 VLAN are Data and Voice.
-          Data VLAN ID is 2 IP 192.168.2.X/255.255.255.0
-          Voice VLAN ID is 200 IP 192.168.22.X/255.255.255.0
-          I created two vlans, in switch, Data and Voice.
-          On the port number 28, it is trunk by default, so I add Data vlan ID 2 tagged.
-          On the port number 26, it is trunk by default, so I add Voice vlan ID 200 tagged.
-          On the port number 27, I add Data vlan ID 2 tagged for Data vlan out.
-          Port settings No.1
I set it up as Trunk with Data vlan 2 untagged, and 200 Tagged (voice vlan). I plugged in a phone with a pc attached. But the PC will get to the vlan 200 to get the DHCP address, but no from vlan 2. The Phone works with correct vlan ip.
-          Port settings No.2
Trunk with vlan 1UP, 2T, and 200T. The phone is even worse. Would never pick up any IP from DHCP.
-          Port settings No.3
Access with 200U...of course the phone will work... and the PC could not get to its own vlan. Instead, the PC got an ip from the voice vlan. Not from VLAN 2.
I have Linksys phone I’m not sure if this help.
For more information I setup in switch,
            - enable voice vlan
- set the port on auto voice vlan
- enable LLDP-MED globally
- create a network policy to assign VLAN 200
- assign this network policy to the port the phone is connected to.
I hope this information help to help me to setup Data and Voice vlans, to plug the phone to work with vlan Voice 200 (IP rang 192.168.22.X), from phone to Pc and pc work as Data vlan 2 (IP rang 192.168.2.X).

I just got done setting up voice VLANs on an SF 300-24P and verified working. This was working with Cisco 7900 series phones connected to a Cisco UC setup.
Here's my sample config.
Note that I edited this by hand before posting, so doing a flat out tftp restore probably won't work. However, this should give you a clue. Also, don't take this as 100% accurate or correct. I've only been working with these things for about a week, though I've worked with the older Linksys SRW switches for a couple of years. I'm a CCNP/CCDP.
VLAN 199 is my management VLAN and is the native VLAN on 802.1q trunks.
VLAN 149 is the data/computer VLAN here.
VLAN 111 is the voice/phone VLAN here.
VLAN 107 does nothing.

SW1 has created the VLAN 100 and enabled as VOICE VLAN
The first 3 octes of the mac of my phone is inserted into Telephony OUI Table
The Auto Voice VLAN Membership is enabled in the port where phone is attached.
The port that is conected to SWCORE has the vlan 100 configured as tagged.
SWCORE has created the VLAN 100 and enabled as VOICE VLAN
The port that is conected to SW1 has the vlan 100 configured as tagged.
The port that is conected to router CME has the vlan 100 configured as tagged.
If I config other port into SWCORE with VLAN 100 tagged I can ping from CME to that host.
Could be the problem a vlan propagation error?
Somebody could help me? I am desperate...
Thank you in advance.

Hi David,
Thank you for the purchase of the switch.
.Like anything, even riding a bike, the switch is actually very easy to configure, if you have a little bit of practice on it..
You mentioned you are using the " Telephony OUI Table" i guess you have a SF300-24P or ordering p/n SRW224G4P-K9-NA. Please be specific with the switch models you are using.
Are you using the older SRW series or the refreshed SRWxxx-K9 (300 series) switch in the core?
Firstly, make sure you are using version 1.1.0.73 of the switch firmware. Do that change now or verify that 1.1.0.73 is the active image on the switch.
The switch has two areas for storing firmware images. It stores the new firmware in the unused image area. Check the administration guide for how to upgrade firmware and select new firmware for the next reboot.
CDP is enabled on the switch when you use the new software, it was not there with older firmware, hence my insistance at upgrading firmware.
( Personally i would prefer you to have a catalyst switch for your ISRG2 CME application, for tech support purposes. But this is the land of the free..)
I found the following when I added my SG300-28P to a VLAN aware UC500.
The UC500 was advertising vlan100 as a voice vlan, configured that by Cisco Configuration Assistant, you might try CCP on your ISR.
I had a IP phone plugged into switch port G7 and a uplink to my UC500 via port Gig27.
The following in blue is a screen copy from my 300 series switch CLI interface.
You will note the switch automatically populated both VLAN and port information, the only command I added was "no passwords complexity enable," and some usernames, which removed from the screen capture below.
the switch basically configured itself.

Switch automatically figures which ports should be tagged into VLAN 100.
I did not tell the switch it was connected to VLAN100. I did not add vlan100 to the VLAN database.
So get the ISR router to advertise VLAN100 as a voice vlan.

Setting up a Test Voice VLAN for Lync 2013

I want to set up a second voice vlan to be a test vlan.
In the current situation the customer has voice and data running on vlan1. The customer insist on taking incremental steps to improve QoS. I have advocated separated vlans for voice and data. They just want to move everything (phase 1) to a different
vlan. They want to see how getting all traffic of vlan 1 will improve there performance. Again, I recommended the best practice, they want to try this approach first.
I am conducting a pilot test with just one cx600 IP phone. and a single switchport. I created a new vlan99 using VTP. I configured the switchports on the Cisco 2960-x switch as follows.
#switchport mode access
#switchport access vlan 99
The phone gets its correct vlan id, and pulls its IP from the correct dhcp scope. However the phone displays "connecting with the lync server" for a long time, then "connecting to download its certificates". This takes a long time then fails.
If I change the switchport back to vlan1 it works fine. What can be the problem? Does the vlan99 need to be defined on the lync server? How many vlans can be supported by Lync 2013?
Thank you,
gigiu

Change voice vlan on specific ports

I need to test a new phone system that is running on vlan 120. The problem is my current voice vlan 110 is still in use for my current phone system. How can I assign a different voice vlan for a single port without having it propagate to the rest of the switch or the other sbs switches in my network?

Hello,
In regards to the Small Business Switches, you can only have a single Voice Vlan configured on them.
Now, since what you are trying to do is to test the connectivity on a single phone, I don't think that you will really have to change or Add a new Voice VLAN, maybe you can get it to work by changing the port to an Access Port with VLAN 120 Untagged, and then they should communicate as long as they are on the same VLAN.
Please let us know if this works, I'm not sure it will since the device is meant to only handle a single Voice VLAN as I said before, but it is worth the try.

SUP failed over manually, voice service failed after FAILOVER, started accessing old voice vlan which was removed from config

Hey guys,
I am pretty sure, my subject is kinda confusing. Sorry about that. Here is what happened.
1. 4510r with Supervisor V 1000BaseX, switched over to standby Sup, then reseated Active SUP, once reseat complete, switched again to get the reseated SUP up and running as Active SUP.
2. a simple maintenance which was supposed to cause no outage and it did not cause any outage as well.
3. however, what i did not notice was, even though the voice vlan was configured to access 2353, they were accessing vlan 453.
4. the change was made 2 weeks prior to this maintenance where voice vlans were previously accessing 453 and they were all changed to access 2353. configs were saved.
5. however, after the maintenance, the running config showed that they were acessing 2353 but when checking the mac address on the interface, it was seen accessing 453.
6. the fix was to remove the config and re add it , that fixed it.
Has anyone else experienced the issue ? What really happened there ?

Silent Monitor and Call record with voice vlan

We are pretty new to CCX, and want to get silent monitor and call recording working. I've read a bunch of troubleshooting docs, and a bunch of the discussions here, but I am still unable to get it to work the way that I want.
Heres the setup. The phones are all set to the recommended settings, and the agent pc is plugged into the phone. The data vlan is 111 and the voice vlan is 222. When I run the nicq prog on the agent pc, it can not find the phone, but I can enter the ip in , and it sees the phone. The supervisor laptop can not monitor or record.
If I change the voice vlan to 111, nicq still can not find the phone, but the supervisor can record and monitor with no problem. Is is an issue with 802.1q and perhaps my nics do not support it?
CCX Ver:
8.5.1.11004-25

Hi
It could be, but it's pretty rare.
Have you enabled 'PC Port Voice VLAN Access' and 'SPAN to PC Port' on the phone?
Have you tried alternate PCs/laptops on the back of that phone?

There is no "Switchport Voice Vlan" command on SF300-24P !!!

Hello everyone
I am in an urgent problem :S
I have a Small Business SF300-24P
I have created two vlans one data and one voice
but i have not assigned them to the ports and I am not sure how to do so since there's no "switchport voice vlan" command under the interface !!
here are the configurations
btw the switchport mode is still trunk as it is by default

Hi Sandy,
You need:

and smart ports should do the rest.

Inter-VLAN routing, Auto-Voice VLAN and IP Address-Helper

Hope that somebody can help me with the setup in the screenshot.
Planning to use Auto-Voice VLAN and Smartports to configure VOIP
LLDP-MED will be enabled on the switch to detect the IP phones so they will be moved to the Voice VLAN (If not the first 6 signs will be added to the OID table). The Voice VLAN ID will be 2 >> Voice VLAN will be automatically enabled once a device is recognized as a IP phone right?
Workstations will be connected to the Cisco switch, VLAN data will be untagged and will remain on the native VLAN.
Smartports will be used to configure the ports (Macro's) >> Should configure the ports as trunks as assigns the correct VLANs right?
But how do i configure the IP Helper-Address? Do i have to create the Voice VLAN on both switches and then run the command "IP Helper Address" to specify a DHCP server? From what i've been reading it's required, when using Inter-VLAN routing, to configure the VLAN interface with an IP address. But it's going to give problems when both switches are connected to eachother and both have the same VLAN configured including the same IP address assigned to their VLAN interface?
Normal data should pass the ASA firewall, VOIP traffic should go through the Vigor modem to a hosted VOIP provider. The best way, i assume, is to configure 2 separate scopes on the DHCP server?
Still confused on how to set it up, hope that someone can point me in the right direction

If you're sending voice to only the Vigor modem then there is no need for a trunk between the SF-300 and the Vigor modem. You can just set that to an untag packet for the VLAN 2 between that switch and the Vigor modem.
On the 'edge' SF300 where the IP phone/PC is it is obviously going to interoute there and of course the phone port is tagged and PC port is untagged.
For the IP helper, it uses UDP-RELAY and it should be enabled on the port itself and enabled on the global configuration. You may also need option 82. Also keep in mind, depending how your DHCP server works, it may need option 82 configured as well or at least a route to understand the subnets in the layer 3 environment to get traffic across the VLANS.

Cisco voice vlans w/ nortel VOIP system

Hello everyone,
I am going to segment a network with a Nortel VOIP system. Right now, the network is completely flat with PCs plugged into the back of the nortel phones. I would like to set up a voice vlan for the nortel phones but am not sure if voice vlans will work w/ non-cisco phones (cdp). Please provide me some insight if you can. Thanks!

If your are Using Recent Cisco Switches it is quite easy.
Using 4006 SUP III core switches or 3560 PSE's should be okay.
If you have Nortel Phase II phones they can also be powered by the 802.3 cisco switches with no probs.
Anyway set the switchport mode to switchport voice vlan. Set spanning tree portfast and configure qos as you see fit on the port. Configure the voice vlan on the switch eg switchport voice vlan 111. You may need to configure the port to switchport mode dynamic desriable as well. Some older switches may have problems but you can enable trunking to cheat and then a default vlan for the pc on the switchport
As regards to the phones when the phone reboots and you enter the configuration mode via flipping the 4 soft keys. You should then see the vlan option and configure the same vlan number on the phone as the cisco switch eg 111.
The phone should then register again without any problems. All i2002/i2004 firmware for last 2 years has the vlan option. I looked after about 400 nortel phones all on cisco switches of various ages with only minor setting up issues.
Best of luck

SG 200 50-P Voice Vlan

Hi all,
I am not familiar with the graphical interface of the SG 200-50P but I need to configure a dual data and voice vlan on a port.
I disabled globally the smarport and Auto Voice Vlan feature on the switch.
Data Vlan : 2
Voice Vlan: 3
All ports connected between the switches and to the Virtual Machine DHCP server are configured as trunk with the Vlan 2 and 3 "TAGGED"
If I connect an IP phone to a trunk port (Vlan 2 Untagged and Vlan 3 Tagged) which i think thats the appropriate way to do it, the phone will get an IP from the scope of the data vlan (192.168.1.x/24).
If I connect the IP phone to a trunk port (Vlan 2 Tagged and Vlan 3 Untagged), the phone will get an IP from the Voice vlan scope (192.168.3.x/24) but the PC attached to the phone will also have an IP from the voice vlan scope.
Please advise

For that problem I configured the following:
Port mode to "General":
vlan2 unttaged
vlan3 tagged
At Media VLan I enabled the Application "voice" and "voice signaling" for that port

Voice Vlan

Hello,
I have an question is kind stupid, but somebody asked me and i have this doubt too.
If i have pc attached to my phone, but i onle have one vlan, the IP Phone and the PC will work?
I know that we can face some problems with this scenario.
Regards
Leonardo Santana

Yes, if the vlan is not defined as "voice vlan" then both PC and phone will get it. If it is defined only as "voice vlan" then only phone will pickup the vlan.
All assuming Cisco infrastructure.

Phone not picking up Voice VLAN

Hi All,
Strange issue that's just started happening with a few 6921 phones.
On our cisco switch when port is configured with data and voice vlan, the phone picks up an IP address from the data vlan and in turn doesn't register. It's as if it doesn't see the voice vlan. As soon I remove the data vlan and have voice vlan only on the port, phone picks up IP from the voice network and registers against the CME. This all worked before on the same ports, nothing changed. It just suddenly stopped working.
Anyone seen this before?
Thanks

Hi,
Ok first output is when the phone doesn't work. VLAN 7 is the data vlan and 81 is Voice on this LAN.
