switchport mode trunk <-- do i need this command?
I want to know the difference between having this command and not.
Go to Solution.
you need it on both!
after you created the port-channel and assigned members
then whenever you change the mode on the port-channel it will be changed on all the members of the port-channel
(as all the members of the port-channel need the same configuration)
View solution in original post
you can configure
- switchport mode trunk
- switchport mode access
1) if neither of these is configured the port will negotiate to form a trunk; if this fails it reverts to mode access
2) if you KNOW it needs to be a trunk -> configure a trunk, this speeds up the port-negotiation before a port becomes active.
3) if not connected to a Cisco switch trunk negotiation may fail -> here also you may want to force mode trunk
-> do you need this? depends on argument above.
I have 'switchport mode trunk' on int port channel 1 but I want to know if it should be in int gi1/ 0/1.
