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.
Note: On E-Series ExaScale systems, TCP ACL flags are not supported in standard or extended ACLs
with IPv6 microcode. An error message is shown if IPv6 microcode is configured and an ACL is entered
with a TCP filter included.
