Etherchannel in standalone mode due to not matching port numbers?

keesepema

A student posted a PacketTracer file in which he configured on switch1 port range  fa0/1-8 in portchannel 1 LACP. On the second switch he configured fa0/17-24 in portchannel 1 LACP.

If I issue

 

 

show eth summary

 

 

on both switches, it shows that the underlying switchports are not in (P) portchannel, but in standalone mode (I).

Should he have configured on both switches the same portnumbers? So on S1 fa0/1-8 and also on S2 fa0/1-8?

Hello @keesepema,

Port numbers do not need to match on both ends. What matters is that the two switches agree on the logical port channel number and the LACP mode.

 port number not effect portchannel status you can select any number but some cisco doc. Suggest use port from same slot (if SW have many slots)
