Port-Channel

[ney25]

Dear netpro,

i've some problem for the port-channel, in the switch port, i saw the port-channel unbundled automatically. what is that means actually ? now the server shows intermittent.

Does anyone encoutered this before ?

Time since last port bundled: 25d:00h:48m:57s Gi4/4

Time since last port Un-bundled: 25d:00h:48m:58s Gi4/4

Hello,

what do you have connected to those ports ? A server with two NICs ?

yes .. this server has 2 NICs and connected to the switch port.

Hello Jack,

from your original post:

Time since last port bundled: 25d:00h:48m:57s Gi4/4

Time since last port Un-bundled: 25d:00h:48m:58s Gi4/4

Do you actually get these log entries frequently ? The message would normally appear when the channle is first formed.

Are the NIC´s Gigabit NIC´s ? Try and force the speed to a fixed setting (100MB Full Duplex) on both the NIC and the switchport, and check if that makes a difference.
