Assigning a DSCP policy for a global IP-device classifier

This global QoS packet-marking option assigns a previously configured DSCP policy (codepoint and 802.1p priority) to outbound IP packets having the specified IP address (or an address within the range specified by the subnet mask) in the source or destination field of their packet header. The switch:

  1. Selects an incoming IPv4 or IPv6 packet on the basis of the source or destination IP address it carries.
  2. Overwrites the DSCP in matching packets with the globally configured DSCP codepoint, and assigns the 802.1p priority associated with the new DSCP.
  3. Forwards the packet through the appropriate outbound port queue.
