Description
A textual description (up to thirty characters) for the service created when adding the port to
a group.
Group ID
The number of the group to which the port is to be added.
Tag

Important Notes
♦
ESX-K and GSX-K Kodiak ASIC-based modules support
802.1p
traffic prioritization. For chassis configurations
that include only ESX-K, GSX-K and/or WSX series
modules,
802.1p
priority bits can be carried inbound on
a tagged port (configured with multiple spanning tree
802.1Q
) across the backplane. This priority information
is used at the egress port to queue the packet, and is
sent out in the packet whether the egress port is tagged
or not.
The ESX-K and GSX-K modules can also remap incom-
ing priority on an ingress port. If priority remapping
has been configured, the new priority will be carried
across the backplane. The priority information is used
to queue the packet, and is sent out in the packet if the
egress port is tagged.
Mode
This field allows you to choose either multiple or single spanning tree. This option only
appears if the module uses 10/100 Ethernet ports. Once you select a type of spanning tree for
a port, the port automatically retains the spanning tree selection for any other group it is
added to.
