[shutdown]
(Optional) Shutdown interface while ACE hit
Mode:
IP ACL Configuration
Usage Guide:
Use the deny command to add deny conditions for an IP ACE that drop those packets hit the ACE. The “sequence”
also represents hit priority when ACL bind to an interface. An ACE not specifies “sequence” index would assign a
sequence index which is the largest existed index plus 20. If packet content can match more than one ACE, the
lowest sequence ACE is hit. An ACE can not be added if has the same conditions as existed ACE. Use “shutdown”
to shutdown interface while ACE hit.
Example:
The example shows how to add an ACE that denies packets with source IP address 192.168.1.80. You can verify
settings by the following show acl command
Switch(config)# ip acl iptest
Switch(ip-al)# deny ip 192.168.1.80/255.255.255.255 any
Switch(ip-al)# show acl
IP access list iptest
sequence 1 deny ip 192.168.1.80/255.255.255.255 any
