different ways on making a port channel

[robertkwild]

hi all,

whats the best way on making a channel group is it -

conf t

int range <g1/0/x-x>

switchport mode trunk

switchport trunk allowed vlan add | remove <ID>

no shut

channel-group 1 mode auto

or -

conf t

int po1

channel-group 1 mode auto

int range <g1/0/x-x>

switchport mode trunk

switchport trunk allowed vlan add | remove <ID>

no shut

thanks,

rob

Hi @robertkwild 

In my opinion, of the two options you indicate, the only valid is the first.

In the second option, at no time do you indicate that the g1/0/x-x interfaces are part of the channel-group, so it will never be part of the portchannel1..

int po1

channel-group 1 mode auto

shutdown

!

int range <g1/0/x-x>

switchport mode trunk

switchport trunk allowed vlan add | remove <ID>

no shutdown

Once both the side confifured and check the config and

int po1

no shut

to be safe
