Solved: Port Channel (Suspended State?? / Monitoring State)

Mavrick25 · ‎08-05-2008

Hey Guys,

I have a problem.

The topolgy is like this..

I have a L2/L3 switch and a L3 router..

I have configured port channel on both.

I have 2 interfaces on the L2/L3 switch referencing the port-channel point to the L3 router..

I have 2 interfaces on the L3 router pointing to the L2/L3 switch..

On the L3 router..

The command "show interface status" shows up/up.

On the L2/L3 switch..

The command "show interface status" shows up/down.

I got this error message on the L2/L3 switch..

MET-DST: %EC-5-CANNOT_BUNDLE2: is not compatible with Gi3/6 and will be suspended (Source monitor interfaces are not allowed to be part of an etherchannel)

****When I changed the port on the L2/L3 switch I see it in monitoring?????***

How come??

Let me know

hi!

Are you runing any SPAN monitoring sessions on the L2/L3 switch? Can you check using "sh monitor sessions" command?

I am guessing you had set a span on this port and have not disabled the SPAN as yet. And hence that port is unable to be a part of the etherchannel.

If this doesnot solve the issue, can you please paste the config of the ports?

You know what..

Your 100% right..

My colleague set monitoring on and didn't tell me..

What does this do?

What is the purpose?

Why did it block me?

Let me know and thanks for your help!

Span allows you to monitor with a sniffer packets on configured ports to look at if you are having a problem . Most useful when you need to look at packets on a given port or vlan. Because it was set as a monitor port it is not allowed to be part of a etherchannel . turn off the span session and it should be fine.
