Avaya P550R, P580, P880, and P882 Multiservice Switch User Guide, v5.3.1
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 match any other ACL rules. The command syntax is:
Avaya(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” on page 8.
Examples
Table 6-153. 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
