Re: STP question// LACP

Hi Steve,

The configs are identical both sides.

I am suspecting
unidirectional link issue. when i do show lacp counters port-channel <ID> it
shows LACP PDU being sent but not received at both ends
I am planning to
enable UDLD and see. But I am wondering can we enable UDLD on a single
port-channel member or it has be enabled on the entire port-channel interface?
can you please assist?

Ramesh

No TCN since STP
is running at the PortChannel level. It will however send
a trap and will how
up in your local log buffer:

If a segment within an EtherChannel fails,
traffic previously carried over
the failed link switches to the remaining
segments within the EtherChannel.
When a failure occurs, the EtherChannel
feature sends a trap that
identifies the switch, the EtherChannel, and the
failed link.

Regarding LACP an suspended link. Could you please provide
interface
configs from all ports on both sides? Are they all identical?
