Modifying 802.1Q Groups
802.1Q groups for both 10/100 and Gigabit Ethernet ports can be modified using the mas
command. The procedure is slightly different in each case. The screens for the mas command
change, depending on whether you have a legacy Ethernet board or a Kodiak ASIC-based
Ethernet board.
Modifying 802.1Q Groups for 10/100 Ports
To modify the configuration of an 802.1Q group for 10/100 ports, use the mas command as
shown:
mas <slot>/<port> <instance>
where <slot> is the slot number of the module on the switch, <port> is the port number where
the service was created, and <instance> is the identifier for the service on this port. For exam-
ple, to modify 802.1Q service instance 1 on port 5 of slot 2, enter:
mas 2/5 1
If this is a legacy Ethernet module, the screen appears as shown:
Slot 2 Port 5 Ethernet 802.1Q Service
1) Tag : 3
2) Priority : 0
If this is a Kodiak ASIC-based module, the screen appears as shown:
Slot 2 Port 5 Ethernet 802.1Q Service
1. Description (30 chars max) :
2. Tag : 0
3. Priority Remap Values :
30. 0 - 0
31. 1 - 1
32. 2 - 2
33. 3 - 3
34. 4 - 4
35. 5 - 5
36. 6 - 6
37. 7 - 7
To change a field setting, enter the line number, an equal sign, and the new value. For exam-
ple, to change the Priority setting to 7, you would enter a 3 (the line number for priority), an
equal sign (=), and a 37, as shown:
3=37
♦ 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.
