To apply an IPX ACL to an interface, perform the following task in interface configuration mode:
Task
Apply a generic filter to an interface.
Modifying ACL TCAM Size
You can change the TCAM size by entering the sdm access-list command. For more information on
ACL TCAM sizes, see the "Configuring Access List Size in TCAM" section on page 77.
Note To increase the ACL TCAM size, you must decrease the TCAM size of another region,
such as IP, IPX, IP multicast, or bridging.
You will need to increase the TCAM size if you see the following error message:
Caution
Warning:Programming TCAM entries failed
Please remove last ACL command to re-activate ACL operation.
!<ACL number or name> <IP or IPX> <INPUT_ACL or OUTPUT_ACL> from TCAM group for
!<interface>
Please see the documentation to see if TCAM space can be
increased on this platform to alleviate the problem.
The TCAM error message is displayed in real time. It is not logged when the specific ACL
Note
is applied to an interface.
