Creating a Layer 4 Protocol ACE

To create a Layer 4 Protocol ACE:

1In the ACL Setup page of the Create ACL wizard, click New. A list of ACEs appears.

2Select New L4 Protocol ACE. The Create L4 Protocol ACE dialog box appears.

3In the Action list, select Permit to allow access if the conditions in the ACE are matched, or Deny to refuse access if the conditions are matched.

4If you select Permit, in the CoS box, specify a class-of-service level for packets. For information, see step 4 in “Creating an IP ACE” on page 309.

5To enable counting of packets filtered by an ACL, select Enable Hit Count.

6Define the IP attributes (source and destination IP addresses, the TOS, and the precedence). The steps are the same as the steps when configuring an IP ACE. See step 6 on page 309 through step 9 on page 310.

7In the Protocol ID box, specify the IP protocol number. Table 26 lists commonly used IP protocol numbers.
