Assigning a DSCP policy for a global source-port classifier
This global QoS packet-marking option assigns a previously configured DSCP policy (codepoint and 802.1p priority) to IP packets received from the specified source-ports. The switch:
Procedure
- Selects an incoming IP packet on the basis of its source-port.
- Overwrites the packet's DSCP with the DSCP configured for matching packets.
- Assigns the 802.1p priority associated with the new DSCP.
- Forwards the packet through the appropriate outbound port queue.
