6509 add vlan to trunk

[lukeprimm]

I have a trunk port that I need to add another vlan to and I am wondering the command to do so?  Right now the particular vlan (vlan 5) is being pruned. My next question is will this be service impacting? Can I do it during the day or will it disrupt the trunk port at all?  Thanks

Hi,

To add a new vlan to the trunk

switchport trunk allowed vlan add xx

make sure to use "add"

adding a new vlan to the trunk should not cause any issues.  You can do it any time.
