Configuration notes for 802.1ad tagging

  • One global tag profile with a number between 0 and 0xffff can be configured on stackable devices.
  • On individual ports, if tag-profile is enabled, it points to the global tag profile.
  • Tag-profile can also be enabled for provisional ports.
  • Tag-type and tag-profile cannot be configured at the same time. You will see the message "un-configure the tag-type to set the tag-profile." It tag-type is already configured, you will need to unconfigure it and then add the tag-profile .
  • Do not use the tag-type command in conjunction with the tag-profile command. If a tag-type has already been configured and you try to use the tag-profile command, you will see an error message telling you to remove the tag-type before you add the tag-profile.
  • For devices operating in an IronStack topology, when a tag-type for a port is changed, the tag-type for all of the ports on a stack unit also changes. Because of this limitation, SAV and Q-in-Q cannot be used at the same time on stacking devices.
