IP Access Control Lists (ACLs)

In the Dell Force10 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 (for more information on ACL supported options see the FTOS Command Reference):
• 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 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 FTOS will assign numbers in the order the filters are
created. The sequence numbers, whether configured or assigned by FTOS, are listed in the

the new entries. Hot Lock ACLs are enabled by default and support both standard and extended ACLs on
all platforms.
Note: Hot Lock ACLs are supported on Ingress ACLs only.
