Hi all,
we have this design in my network:
- Switches staking connceted 2960X to Core switch 4507.
- Tahre two links between the access switchs (stacking) and the core switch configured in etherchannel on mode.
evry time we have a a traffik bloked in same vlan for example in vlan camera or vlan voice.This problem is solved only when I restart the stack.
any one can help me please?
Regards,
Salah

Have you checked STP configuration to determine what VLAN traffic is allowed/blocked?

Try show spanning-tree mst [interface-id] in priveledge EXEC mode. Show running-config can also help.

Hi Jason,

Question: Are all port channels encapsulated dot 1 q? Also re-verify that all of your configured VLAN’s still exist.

yes all vlan are allowed in etherchannel ports and the bellow example configuration for etherchannel ports:
interface Port-channel1
switchport trunk native vlan 32
switchport trunk allowed vlan 2-4094
switchport mode trunk
****
interface GigabitEthernet2/0/49
switchport trunk native vlan 32
switchport trunk allowed vlan 2-4094
switchport mode trunk
ipv6 traffic-filter NoIPv6 in
keepalive 10

Is all traffic blocked for VLAN Voice and VLAN Camera or is ‘some‘ VLAN Voice/Camera able to transmit over the etherport? is port security configured for any of the interfaces?
