Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

In Dell Networking switch/routers, you can create two different types of IP ACLs: standard or extended.

For more information about ACL options, refer to the Dell Networking OS Command Reference Guide .

For extended ACL, TCP, and UDP filters, you can match criteria on specific or ranges of TCP or UDP ports. For extended ACL TCP filters, you can also match criteria on established TCP sessions.

When creating an access list, the sequence of the filters is important. You have a choice of assigning sequence numbers to the filters as you enter them, or the Dell Networking operating system assigns numbers in the order the filters are created. The sequence numbers are listed in the display output of the show config and show ip accounting access-list commands.

Ingress and egress hot lock ACLs allow you to append or delete new rules into an existing ACL (already written into CAM) without disrupting traffic flow. Existing entries in the CAM are shuffled to accommodate the new entries. Hot lock ACLs are enabled by default and support both standard and extended ACLs.
