VLAN Prunning to the remote closet

[b.withrow]

We are doing vlan prunning to all of our remote wiring closets. I need to add a vlan to the list of vlan's to be trunked to a specific closet. the line in the config currently says:

set trunk 3/9 on dot1q 1,208,395,470,730,740,745

I want to add 665 to the list. Should I just type:

set trunk 3/9 on dot1q 1,208,395,470,665,730,740,745

will this make the netowrk "hiccup"? I would like to do it during business hours, but if it will cause problems I'll schedule a time. Thanks!

Hi,

allowing another VLAN on a trunk should have no impact to your network (The only effect should be a STP TCN sent in VLAN 665). I've done it several times during business hours.

Just use

set trunk 3/9 665

command and it will add VLAN 665 to the allowed list on port 3/9. (Don't forget to allow it on the other trunk side.)

(I suppose VLAN 665 is already existing in your network. If not, you have to create it using set VLAN 665 name .... command on a VTP server first.)
