to 149.36.184.255. A wildcard mask must not contain leading
zeroes. For example, a wildcard mask of 010.010.011.010 is
invalid, but a wildcard mask of 10.10.11.10 is valid.
■ Match DSCP — Matches the packet DSCP value to the ACL. Either
the DSCP value or the IP Precedence value is used to match packets to
ACLs.
■ Match IP Precedence — Matches the packet IP Precedence value to
the rule. Either the DSCP value or the IP Precedence value is used to
match packets to ACLs.
■ Action — Defines the ACL forwarding action. In addition, the port
can be shut down, a trap can be sent to the network administrator, or
packet is assigned rate limiting restrictions for forwarding. The options
are as follows:
■ Permit — Forwards packets which meet the ACL criteria.
■ Deny — Drops packets which meet the ACL criteria.
■ Shutdown — Drops packet that meets the ACL criteria, and
disables the port to which the packet was addressed. Ports are
reactivated from the
