80-Series QoS
Setting Up a Default ACL Rule
Command
Use the any keyword in the access list command to set up a default ACL
rule. The rule will be applied to all packets on the switch that do not match
any other ACL rules. The command syntax is:
(
configure)#
access-list <access-list-name> <access-list-index>
{permit [{use-priority <priority> | use-diffserv [mask] | remark-diffserv
<dscp> [mask] | use-l2}] | fwd1 | fwd2 | fwd3 | fwd4 | fwd5 | fwd6 | fwd7 |
fwd8} any
The default ACL rule must have the highest index in the ACL. To ensure
that the switch never applies the default ACL rule to traffic that matches
other ACL rules, Avaya recommends that you use an index of 512 for the
default ACL rule.
For more information about how default ACL rules work, see “ Classifying
Traffic by Layer 3 or Layer 4 Characteristics ” earlier in this chapter.
Examples
Table 25-17. Default ACL Rules
To... Enter...
Use the DSCP in the packet to classify
all traffic that does not match any
other ACL rule. access-list MyAcessList1 512 permit
use-diffserv any
Replace the existing DSCP with a
DSCP of 63 for all traffic that does not
match any other ACL rule.
The switch uses the new DSCP of 63
to classify the packets.
access-list MyAcessList1 512 permit
remark-diffserv 63 any
Use the layer 2 priority in the packet
to classify all traffic that does not
match any other ACL rule. access-list MyAcessList1 512 permit
use-l2 any
Assign a priority of 4 to all traffic that
does not match any other ACL rule. access-list MyAcessList1 512 permit
use-priority 4 any
