Catalyst 1300 Voice interface Configuration

[abc1235]

Hallo,

I have a Catalyst 1300 that I want to use as an access switch for some telephones and APs. I have followed the config guide but the telephone is not getting an IP address from our DHCP server. The voice vlan has been set and the interface configured as below:

Test-999CI1300#sh voice vlan
Administrate Voice VLAN state is auto-enabled
Operational Voice VLAN state is auto-enabled
Best Local Voice VLAN-ID is 251
Best Local VPT is 5 (default)
Best Local DSCP is 46 (default)
Agreed Voice VLAN is received from switch 84:5a:3e:90:1f:62
Agreed Voice VLAN priority is 0 (active static source)
Agreed Voice VLAN-ID is 251
Agreed VPT is 5
Agreed DSCP is 46
Agreed Voice VLAN Last Change is 24-Oct-24 00:05:17

Test-999CI1300#sh run int g1
interface GigabitEthernet1
spanning-tree portfast
switchport access vlan 251
!

Could I be missing any config? I'll appreciate your input.

Have you set the IP helper on the VLAN interface?

Hallo @Roger Kallberg. That is already configured on the ISR1100 router and the voice vlan to the dhcp and it can be pinged. 

[Roger Kallberg]

Please share your running configuration so that we can verify it.

[Nithin Eluvathingal]

You have only configured switchport access vlan 251, but for the phone to get an IP from the voice VLAN, you need the command switchport voice vlan 251. I’m not sure how to configure that on the C1300, but this is how it works on other Cisco models.

@Nithin Eluvathingal C1300 configs are different, so that is for any other switch but the C1200 and C1300
