ACL configuration and management 10

3.Enter the deny command to create a rule in the MAC ACL to drop traffic with the source MAC address.

switch(conf-macl-std)#deny 0022.3333.4444 count

4.Enter the permit command to create a rule in the MAC ACL to permit traffic with the source MAC address.

switch(conf-macl-std)#permit 0022.5555.3333 count

5. Use the seq command to create MAC ACL rules in a specific sequence.

switch(conf-macl-std)#seq 100 deny 0011.2222.3333 count switch(conf-macl-std)#seq 1000 permit 0022.1111.2222 count

Creating an extended MAC ACL and adding rules

NOTE

You can use the resequence command to change all the sequence numbers assigned to the rules in a MAC ACL. For detailed information, see “Reordering the sequence numbers in a MAC ACL” on page 104.

The MAC ACL name length is limited to 64 characters.

To create an extended MAC ACL and add rules, perform the following steps from privileged EXEC mode.

1.Enter the configure terminal command to access global configuration mode.

2.Create an extended MAC ACL and enter ACL configuration mode.

switch(config)#mac access-list extended test_02

3.Create a rule in the MAC ACL to permit traffic with the source MAC address and the destination MAC address.

switch(conf-macl-ext)#permit 0022.3333.4444 0022.3333.5555

4. Use the seq command to insert the rule anywhere in the MAC ACL.

switch(conf-macl-std)#seq 5 permit 0022.3333.4444 0022.3333.5555

5. Enter the copy command to save the running-config file to the startup-config file.

switch(conf-macl-std)#do copy running-config startup-config

Modifying MAC ACL rules

You cannot modify the existing rules of a MAC ACL. However, you can remove the rule and then recreate it with the desired changes.

If you need to add more rules between existing rules than the current sequence numbering allows, you can use the resequence command to reassign sequence numbers. For detailed information, see “Reordering the sequence numbers in a MAC ACL” on page 104.

Use a sequence number to specify the rule you wish to modify. Without a sequence number, a new rule is added to the end of the list, and the existing rule is unchanged.
