Cisco Contest #1
Because it's fun, here is a quick contest when you have to find the difference between the same show command, and find why this output is not twice the same :
First :
SW3#sh int po 2 tru Port Mode Encapsulation Status Native vlan Po2 on n-802.1q trunking 1 Port Vlans allowed on trunk Po2 1-4094 Port Vlans allowed and active in management domain Po2 1,100,200,300 Port Vlans in spanning tree forwarding state and not pruned Po2 none
Second :
SW3#sh int po 2 tru Port Mode Encapsulation Status Native vlan Po2 on 802.1q trunking 1 Port Vlans allowed on trunk Po2 1-4094 Port Vlans allowed and active in management domain Po2 1,100,200,300 Port Vlans in spanning tree forwarding state and not pruned Po2 none
Don't focus on the fact that it is an etherchannel, it's not the subject here.
So, what is different, and -why- ?
Have Fun,
Thomas

Well, non en fait c’était une typo que j’avais pas vue (et que j’ai corrigé)

n-802.1q? negotiated, l’encapsulation a été négociée car elle n’était pas explicitement indiquée dans la conf des interfaces…?

le n-802.1q, il n’a pas été spécifié “encapsulation dot1q” sur l’une des extremité et cela a donc été négocié… d’ou la mention n-802.1q.
