Hi every body!

my book defines active vlan as vlan which is defined on switch and and has ports assigned to it.


However ,same book shows the out put of " show vlan"


vlan name status ports

2 vlan 0002 active fa0/4

5 vlan 0005 active

The vlan 5 is shown as active though no port is assigned to it which contradicts the book definition of active vlan.

Any thoughts?

Thanks a lot!

The other thing that will put a VLAN into the active state is if there is a trunk port on the switch which carries traffic for that VLAN. Does this switch have a trunk port which has VLAN 5 as one of its VLANs?

Thanks Rick for your reply!

well book just shows the output of " show vlan" for illustrative purpose , i believe.


Your point makes sense because if switch has trunk carrying vlan 5, then it is regarded as active as well.


Thanks a lot!
