To filter traffic on Telnet sessions, use only standard ACLs in the access-class command.
Counting ACL Hits
You can view the number of packets matching the ACL by using the count option when creating ACL
entries.
In the MXL switch, you can configure either count (packets) or count (bytes). However, for an ACL with
multiple rules, you can configure some ACLs with count (packets) and others as count (bytes) at any
given time.
1. Create an ACL that uses rules with the count option. Refer to Configuring a Standard IP ACL Filter.
2. Apply the ACL as an inbound or outbound ACL on an interface. Refer to Assign an IP ACL to an
Interface.
3. View the number of packets matching the ACL.

Configure Ingress ACLs
Ingress ACLs are applied to interfaces and to traffic entering the system.
These system-wide ACLs eliminate the need to apply ACLs onto each interface and achieves the same
results. By localizing target traffic, it is a simpler implementation.
To create an ingress ACL, use the ip access-group command in EXEC Privilege mode. The example
shows applying the ACL, rules to the newly created access group, and viewing the access list.
Example of Applying ACL Rules to Ingress Traffic and Viewing ACL Configuration
To specify ingress, use the in keyword. Begin applying rules to the ACL with the ip access-list
extended abcd command. To view the access-list, use the show command.
