IP Access Control Lists (ACLs)
In Dell Networking switch/routers, you can create two different types of IP ACLs: standard or extended.
A standard ACL filters packets based on the source IP packet. An extended ACL filters traffic based on the
following criteria:
• IP protocol number
• Source IP address
• Destination IP address
• Source TCP port number
• Destination TCP port number
• Source UDP port number
• Destination UDP port number
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
