To apply an IP ACL (standard or extended) to a physical or port channel interface, use these commands in
the following sequence in the INTERFACE mode:
To view which IP ACL is applied to an interface, use the
show config
command (Figure 232) in the
INTERFACE mode or the
show running-config

Use only Standard ACLs in the
access-class
command to filter traffic on Telnet sessions.
Counting ACL Hits
You can view the number of packets matching the ACL by using the
count
option when creating ACL
entries. E-Series supports packet and byte counts simultaneously. C-Series and S-Series support only one
at any given time.
