Port Channel Between Two 3560s flashing orange lights

[dbuckley77]

We have a pagp port channel set up between two 3560 switches.  One of the switches shows the port channel in blocking for one of our vlans and the leds' for these ports are flashing orange.  There are no duplex or speed mismatches.  Is the STP blocking causing this?

[Reza Sharifi]

Can you provide "sh run" from both switches and also the output of "sh ether-chan summary"?

Hi!

The switch configuration seems alright (Assuming you want that Port channel to work as access) and the port channel is operating correctly.

If you are seeing one port blocked by STP in the show spanning-tree vlan 7 output then yes, the blinking LED in the switch is because of this reason, STP is blocking one side of the port-channel (The no-designated port).

Hope it helps, best regards!

JC

The port-channel appears to be functioning properly and we're having no STP issues with this vlan.  Does that mean the orange lights are a normal condition to be expected and not a cause for alarm?

[Carlos Villagran · Accepted solution]

Hi!

Hmmm... I cannot really guarantee you that until you give us the show spanning-tree VLAN 7 output from both switches. 

However, I am almost certain this is not a critical problem that could impact your network.

Regards!
