Packets Carrying Specific IP Addresses

Assigning a DSCP Policy Based on IP Address

This option assigns a previously configured DSCP policy (codepoint and
802.1p priority) to outbound IP packets having the specified IP address (either
source or destination). That is, the switch:
1. Selects an incoming IPv4 packet on the basis of the source or destination
IP address it carries.
2. Overwrites the packet's DSCP with the DSCP configured in the switch for
such packets, and assigns the 802.1p priority configured in the switch for
the new DSCP. (Refer to "Differentiated Services Codepoint (DSCP)
Mapping" on page 6-58.)
3. Forwards the packet through the appropriate outbound port queue.
"Mixing" ToS DSCP policies and 802.1p priorities is not recommended. Refer
to the Note on page 6-10.
For more on DSCP, refer to "Terminology" on page 6-6.
Steps for Creating a Policy Based on IP Address. This procedure
creates a DSCP policy for IPv4 packets carrying the selected IP address
(source or destination).
1. Identify the IP address you want to use as a type for assigning a DSCP
policy.
