I have two switches (A, and B) created with same VLAN name of alpha, for fault tolerance B will be a backup to A.

I have a pc on Switch B connected to a port on  alpha VLAN which can ping the firewall in Switch A, the firewall is connected to the untrusted port. But the PC from Switch B cannnot ping anything in VLAN alpha of switch A.

Does anyone have a solution?

Is the firewall on switch A connected to an access port in the "alpha" VLAN or is it connected to a trunk port?

An access port can only carry traffic for a single VLAN. A trunk port can carry traffic for many VLANs.

What kind of switch is this?

Is there only the one VLAN or do you have multiple VLANs?

Can you post the config of the switches.

I have changed the following in the switch :

interface port-channel 1
switch port trunk allowed vlan 235

It started to work
