Channel-group mode on question

[Hubsi-Smith]

Hello,

I try to play around with Packet Tracer and channel-groups.

I added 2 c2960 switch and both gi Ports are channel group mode on.

When I shutdown gi0/1 I could still ping the other switch. But when I add no shutdown, I could see, that both connection got a orange circle and I got some ping timeouts. Depends this on the choosen channel group mode?

I put both running-config files as packet Tracer export files here:

i am not a user of packet tracer, sometimes these virtual environments may not get what you see in the physical as kit as results.

but i see some inconsistency in config switch 1 and 2 below :

interface Port-channel1
switchport trunk allowed vlan 1,20
switchport mode trunk

Hello,

it doesn't matter whether you use PAgP (mode on) or LACP (mode active), once you 'no shut' a member interface, the entire port channel needs to reconverge and hence will go down for several seconds.
