Established Flag - Dell Force10 MXL Blade Configuration Manual

To configure a filter for an extended IP ACL without a specified sequence number, use any or all of the
following commands in IP ACCESS LIST mode:
Command Syntax
{deny | permit} {source mask | any | host
ip-address} [count [byte]] [order] [fragments]
{deny | permit} tcp {source mask] | any | host
ip-address}} [count [byte]] [order] [fragments]
{deny | permit} udp {source mask | any | host
ip-address}} [count [byte]] [order] [fragments]
Figure 5-11
The filters were assigned sequence numbers based on the order in which they were configured (for
example, the first filter was given the lowest sequence number). The
LIST mode displays the two filters with the sequence numbers 5 and 10.
