302-08MP Voice Vlan issue

[philip.lock]

Hi,

I have a 302-08Mp attached to my network, it is plugged directly into a C3560G, however when i plug a phone into this switch i get a 'configuring ip' message up on the phone. The voice vlan is set identical to the 3560 but in the logs i get an error message stating

%CDP-W-VOICE_VLAN_MISMATCH: voice VLAN mismatch detected on interface gi1.

Can anyone help me solve this issue?

Thanks in advance

Hi Phillip, can you post the config of the port connection that go to each other from each switch? What is the management, data and voice vlan?

What software are you running on the SX300?

Tom,

Sorry for teh delay i needed to get someone at the remote location i could trust to reboot the unit. The voice vlan is 20 and the rest run on vlan 1

the 302  is set as

interface gigabitethernet1

macro description "switch | no_switch | switch | no_switch | switch | no_switch

| switch | no_switch | switch | no_switch | switch | no_switch"

exit

macro auto disabled

macro auto processing type host enabled

macro auto built-in parameters ip_phone_desktop $max_hosts 10 $native_vlan 1

and runs sw version 1.1.2.0

the 3560 is set

interface GigabitEthernet0/3

description Link to SW3

power inline never

switchport trunk encapsulation dot1q

switchport mode trunk

switchport voice vlan 20

srr-queue bandwidth share 10 10 60 20

srr-queue bandwidth shape  10  0  0  0

queue-set 2

The voice vlan maco is disabled on the SF300.

You'd have to manually configure the port with that current config

config t

int gi01

switchport mode trunk

switchport trunk native vlan 1

switchport trunk allowed vlan add 20

The phone port configuration would have to match as well

Thanks Tom, do the phone ports also need to be set for trunk mode?

[Tom Watts]

yes

Thanks Tom, at least now i get the ip address its just a shame the phone now comes up with a 'error pass limit' message when you attempt to use it
