This command allows you to override the priority level mappings at the
port level by assigning the packets a temporary priority. Note that this
assignment is made when a packet is received on the ingress port and
before the frame is forwarded to the egress port. Consequently, you need
to configure this feature on the ingress port.
For example, you can configure a port so that all ingress frames are
assigned a temporary priority level of 5, regardless of the actual priority
levels in the frames themselves.
A temporary priority level applies only while a frame traverses the
switching matrix of the stack. Tagged frames leave the stack with the
same priority level they had upon entering the stack.
Examples
This command sets the temporary priority level to 5 on ports 1.5, 1.8, and
2.12 to 2 15:
set switch port=1.5,1.8,2.12-2.15 priority=5
This command activates the priority override feature on port 5.6 so that the
port applies its temporary priority level to all ingress tagged packets:
set switch port=5.6 overridepriority=yes
