Big problem port channel bloked same vlans

[salah gobbaa]

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?

[salah gobbaa]

Hi Jaston,

I used the MSTP with two instances(mode vtp) and in the etherchannel ports all vlans are allowed except vlan id1 .

and if you can assiste me?  how can i check STP configuration to determine what VLAN traffic is allowed.

Thank you for your help.

[Colotarioj]

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

[salah gobbaa]

Hi Jason,

find below

sh spanning-tree mst interface po1 and show running config.

and when I apply this config the situation becomes more stable but still there are problems

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

[salah gobbaa]

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

channel-group 1 mode on

interface GigabitEthernet3/0/49

switchport trunk native vlan 32

switchport trunk allowed vlan 2-4094

switchport mode trunk

ipv6 traffic-filter NoIPv6 in

keepalive 10

channel-group 1 mode on

[salah gobbaa]

HI all,

any update please for my problem??

best regards

Salah

[Colotarioj]

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?

[salah gobbaa]

hi,

you will find below two examples for a vlan camera interface and one for vlan telephony and all vlan traffic cameras and vlan phone are stuck for this switch stack

How many devices are communicating over the ether channel? Also please check your syslogs for error messages when the issue occurs.
