Hi All.
I'm just worried that above subjet command will be used in first time in our switching environment.
Basically, all of vlans are allowing in x-over trunk interface. Btw, we don't want to allow specific vlan a, vlan b.
the work procedure will be happening on primary device as following
primary)
inteface port-channel x/x
switchport trunk allwoed vlan except vlan a, b
secondary)
interface port-channel x/x
switchport mode trunk
-- allowed vlan
once primary device is done, and then we will move to secondary device to modify.
primary)
inteface port-channel x/x
switchport trunk allwoed vlan except vlan a, b
secondary)
interface port-channel x/x
switchport trunk allwoed vlan except vlan a, b
STP is defined basically. so, above work procedure will be safe? it's our core device so I guess it will be ok. but, I would like to get knowhow to avoid unexpected situation during change window.
Thanks.
