Usage Guidelines
You can apply named or numbered standard or extended IP access lists to an interface. To define an
access list by name, use the ip access-list global configuration command. To define a numbered access
list, use the access list global configuration command. You can used numbered standard access lists
ranging from 1 to 99 and 1300 to 1999 or extended access lists ranging from 100 to 199 and 2000 to
2699.
The switch must be running the metro IP access image for Layer 3 support.
You can use this command to apply an access list to a Layer 2 interface (port ACL) or Layer 3 interface.
However, note these limitations for port ACLs:
•
•
•
•
OL-9640-10
ip access-group {access-list-number | name} {in | out}
no ip access-group [access-list-number | name] {in | out}
The number of the IP access control list (ACL). The range is 1 to 199 or
1300 to 2699.
The name of an IP ACL, specified in the ip access-list global configuration
command.
Specify filtering on inbound packets.
Specify filtering on outbound packets. This keyword is valid only on
Layer 3 interfaces.
Modification
This command was introduced.
You can only apply ACLs in the inbound direction; the out keyword is not supported for Layer 2
interfaces.
You can only apply one IP ACL and one MAC ACL per interface.
Port ACLs do not support logging; if the log keyword is specified in the IP ACL, it is ignored.
An IP ACL applied to a Layer 2 interface only filters IP packets. To filter non-IP packets, use the
mac access-group interface configuration command with MAC extended ACLs.
