80-Series QoS
■
Replace the existing DSCP with a DSCP that you specify
■
Use the layer 2 priority
You can specify the TCP/IP traffic that you want the rule to apply to.
The rule can apply to traffic with a specific:
■
IP destination address
■
IP source address
■
IP Protocol
■
Destination TCP or UDP port
■
Source TCP or UDP port
The priority that is specified by an ACL takes precedence over all
other priorities. Because of this precedence, the switch determines
whether a rule in an ACL exists for an IP packet in the final stage of
classification. If an ACL exists, the priority associated with the ACL
replaces the current priority of the frame.
For information on how to set a rule in an ACL, see “
Using a Default
ACL Rule
By default, the switch classifies packets by their layer 2 priority, if
they do not match an ACL rule. However, you can set up a default
ACL rule that the switch will apply to all packets that do match any
other ACL rules. This default ACL rule sets a default characteristic,
other than the layer 2 priority, that the switch will use to classify the
packets.
For example, if you set up the following ACL rules:
■
access-list List1 1 fwd2 10.10.60.0 0.0.0.255
■
access-list List1 2 fwd4 10.10.70.0 0.0.0.255
■
access-list List1 3 permit use-priority 4 10.10.80.0 0.0.0.255
■
access-list List1 4 permit use-priority 6 10.10.90.0 0.0.0.255
■
access-list List1 5 fwd1 10.10.100.0 0.0.0.255
■
access-list List1 6 fwd4 10.10.110.0 0.0.0.255
■
access-list List1 7 fwd7 10.10.120.0 0.0.0.255
■
access-list List1 8 fwd8 10.10.130.0 0.0.0.255
■
access-list List1 512 permit use-priority 6 any (default ACL rule)
