Unsupported Features on the Catalyst 3550 Switch
While the Catalyst 3550 switch supports many types of ACLs, it does not provide support for these IOS router ACL-related features:
Non-IP protocol ACLs.
Bridge-group ACLs.
IP accounting.
Inbound and outbound rate limiting (except with QoS ACLs).
IP packets with a header length of less than 5 are not access controlled (an ICMP parameter error results).
Reflexive ACLs.
Dynamic ACLs (except for certain specialized dynamic ACLs that are used by the switch-clustering feature).
For Layer 2 port ACLs, the switch does not support logging or outbound ACLs.
