Configuring 802.1q tag-type translation
The introduction of 802.1q tag-type translation provides finer granularity for configuring multiple
802.1q tag-types on a single device, by enabling you to configure 802.1q tag-types per port group.
This enhancement allows for tag-type translation from one port group to the next on tagged
interfaces.
802.1Q tag-type translation enables you to configure 802.1q tag-types per port group, allowing for
