Hello All,

I have a bit strange situation. Port channel interface has only 1 member, G1/0/3, but the bandwidth displays 2 Gbit. In addition, if I add one more member interface, the bandwidth becomes 3 Gbit. Does anyone have any ideas? What has happened there?

Probably a cosmetic anomaly (read bug) with the IOS . Also check channel with the show etherchannel summary and make sure it only sees one interface in the channel .

Actually, there are 5 port channel interfaces but only one interface has this problem. The others seem to be Ok.

Regarding the IOS, it is running 12.2(35)SE5.
