VLAN 1 and 1002-1005

[haa33110]

Hi, all!

Please teach me! Why we must configure VLAN 1

and 1002-1005 at trunk link? I don't use Token

Ring and FDDI.

There was none who can solve this question at

my ex-office.

Thanks to all.

You don't need those on the trunk link unless you are using vlan 1 for a subnetwhich is not good practice . Vlans 1002-5 are not needed at all on the trunk and should not be there . There are there by default when you create the trunk but do not need to be there , manually prune them off along with any other unneeded vlans .

Something like fish scales fell down from my eyes.

Thanks, Gen. Grant!
