Dell Force10 S4810P - Configure an Extended IP ACL

Access Control Lists (ACLs) | 113
Configure an extended IP ACL
Extended IP ACLs filter on source and destination IP addresses, IP host addresses, TCP addresses, TCP
host addresses, UDP addresses, and UDP host addresses.
Since traffic passes through the filter in the order of the filter’s sequence, you can configure the extended
IP ACL by first entering the IP ACCESS LIST mode and then assigning a sequence number to the filter.
Configure filters with sequence number
To create a filter for packets with a specified sequence number, use these commands in the following
sequence, starting in the CONFIGURATION mode:
When you use the
log keyword, CP processor logs details about the packets that match. Depending on how
many packets match the log entry and at what rate, the CP may become busy as it has to log these packets’
details.
Note: On E-Series ExaScale systems, TCP ACL flags are not supported in an extended ACL with IPv6
microcode. An error message is shown if IPv6 microcode is configured and an ACL is entered with a TCP
filter included.
