CLI – This example shows the switch configured with primary VLAN 5
and secondary VLAN 6. Port 3 has been configured as a promiscuous port
and mapped to VLAN 5, while ports 4 and 5 have been configured as a
host ports and associated with VLAN 6. This means that traffic for port 4
and 5 can only pass through port 3.
Class of Service Configuration
Class of Service (CoS) allows you to specify which data packets have
greater precedence when traffic is buffered in the switch due to
congestion. This switch supports CoS with four priority queues for each
port. Data packets in a port’s high-priority queue will be transmitted before
those in the lower-priority queues. You can set the default priority for each
interface, and configure the mapping of frame priority tags to the switch’s
priority queues.
Layer 2 Queue Settings
Setting the Default Priority for Interfaces
You can specify the default port priority for each interface on the switch.
All untagged packets entering the switch are tagged with the specified
default port priority, and then sorted into the appropriate priority queue at
the output port.
