CBS350 VOIP server issue

[Richard Tapp]

Just wondering if anyone else has come across this issue.

We were migrating from a 2960S switch to a CBS350 switch. They have data VLAN 10 and VOIP VLAN 100.

We tried with one user phone migrated and the VOIP server, VOIP server on a port which is 'switch port access vlan 100'. Configured the same on both switches.

The phone will get an IP, but not register for voice services. If I move the VOIP server back to its original VLAN 100 port on the 2960S it all works fine. So I know VLAN 100 is propogating OK between switches via the 1111-8P router. Even if I put the VOIP server into VLAN 100 on the 1111-8P I get the same result.

Not sure if we need to leave it a bit longer, probably only left it for 5 minutes. But it does work as sonn as the VOIP server is pu tback into the 2960S

Hi Richard,

When you move the server to the 350 switch, are you able to ping it?

Please move back the voip server to the 2960 switch and perform a show mac address-table interface x/x/x using interface where the server is connected to.. Than move it back to the 350 and do the same command on 2960. (i guess the 2960 is connected to 350)

Please let me know

Regards

Carlo

It was not clear and posted on the post

what is Gig1 Interface config on Cisco CBS 350 and what config on Cisco1K gig0/1/1 config

I see the configuration you post have trunk and also access configuration, if you using Trunk and allowed vlan i suggest to remove access vlan X

Also on CBS remove smart macro configuration use just like tradinal way config data and voice config (where both side Trunk and access port)

I also noticed that you are interconnecting two switches through a c1111 which is a Router.

Make sure that ports on router are correctly configured and VLANS defined on it.

Let me know 

Cheers

Just going to try this config on the phone data ports, as we have the same in another office and it works ok there.

interface GigabitEthernet4
switchport access vlan 10                (data vlan)
switchport trunk allowed vlan 100     (voip vlan)
no macro auto smartport

Hi Richard,

Switchport trunk commands, take effect once the port is placed in switchport mode trunk and , to forward untagged traffic on a trunk you should configure switchport trunk native vlan instead of switchport access VLAN.

That said , please preform the commands I earlier suggested and post the output.

Thanks

Regards

It worked with this in the end

User ports

interface GigabitEthernet8
spanning-tree guard root
switchport mode general
switchport general allowed vlan add 60 tagged
switchport general allowed vlan add 1 untagged

and just 'switch port access vlan 60' on the port where the VOIP GW is connected

Thanks for all your help
