Displaying a list of ACL entries
2
access-list 1 deny host 209.157.22.26 log
access-list 1 deny 209.157.22.0 0.0.0.255 log
access-list 1 permit any
access-list 101 deny tcp any any eq http log
The software will apply the entries in ACL 1 in the order shown and stop at the first match.
Thus, if a packet is denied by one of the first three entries, the packet will not be permitted by
the fourth entry, even if the packet matches the comparison values in this entry.
4. Enter the command end on a separate line at the end of the file. This command indicates to
the software that the entire ACL list has been read from the file.
5. Save the text file.
6. On the Brocade device, enter the following command at the Privileged EXEC level of the CLI.
copy tftp running-config <tftp-ip-addr> <filename>
NOTE
This command will be unsuccessful if you place any commands other than access-list and end
(at the end only) in the file. These are the only commands that are valid in a file you load using
the copy tftp running-config… command.
7. To save the changes to the device’s startup-config file, enter the following command at the
Privileged EXEC level of the CLI.
write memory
Here is a complete example of an ACL configuration file.
no access-list 1
no access-list 101
access-list 1 deny host 209.157.22.26 log
access-list 1 deny 209.157.22.0 0.0.0.255 log
access-list 1 permit any
access-list 101 deny tcp any any eq http log
end
NOTE
Do not place other commands in the file. The Brocade device reads only the ACL information in the
file and ignores other commands, including ip access-group commands. To assign ACLs to
interfaces, use the CLI.
Displaying a list of ACL entries
The show access-list and show ip access-list commands displays ACL entries with line numbers.
Numbered ACLs
To display the contents of numbered ACLs, enter a command such as the following.
ServerIronADX# show access-list 99
Standard IP access list 99
deny host 1.2.4.5
deny host 5.6.7.8
permit any
Syntax: show access-list <acl-num> | all
