Important Considerations
■
You need not reboot the system for the changes to take effect.
However, depending on the number of VLANs that are affected, the
system may take several minutes to return control to you.
■
If you modify the tagging type of a backplane port on a switching
module, make sure that you modify the tagging type of the
corresponding port on the switch fabric module.
■
If tagging is enabled for a port, the software uses the VID as the
802.1Q tag.
■
If you modify the default VLAN, you can only change the member
ports or the tag status. You cannot change the name or the VID.
■
If you modify the tagging for a port shared by another VLAN, verify
that the new tag type does not conflict with the port’s tag type in
another VLAN. (A shared port can use a tag type of
none
for only one
of its VLANs; for all other VLANs to which it belongs, the shared port
must use IEEE 802.1Q tagging.)
