The prioritization commands (
map
and
no map)
described in this chapter apply
strictly to the BelAir node that you are currently logged on to. You must repeat
them on each related BelAir node. For example, when specifying that particular
VLAN traffic has a particular priority, you must execute the associated
commands on each possible BelAir node in the path of that VLAN.
Prioritizing Traffic Based
on User Priority Bits
/qos/set up-to-queue-mapping <priority> <queue_id>
This command instructs the BelAir100SN to process packets with the specified
User Priority value to the specified priority queue. The
priority
parameter
ranges from 0 to 7. The
queue_id
parameter ranges from 0 to 3, as described in
Table 12 on page 161 .
Note: Settings made with the
set vlan-to-queue-mapping
command have
precedence over settings made with this command.
Table 13 shows how User Priority values are processed to priority queues by
default.
To unmap a previously set priority, use the
set up-to-queue-mapping
command
to map that priority back to the default priority queue as shown in Table 13 .
Prioritizing Traffic using
VLAN IDs
/qos/set vlan-to-queue-mapping <vlan_id> {none|<queue_id>}
/qos/show vlan {all|id <2-2814>}
The
set
command instructs the BelAir100SN to process packets from the
specified VLAN to the specified priority queue. The
vlan_id
parameter ranges
