22show access-group mode interface
To display the ACL configuration on a Layer 2 interface, use the show access-group mode interface command.
show access-group mode interface [interface interface-number]
Syntax Description
interface
(Optional) Interface type; valid values are ethernet, fastethernet, gigabitethernet, tengigabitethernet, and port-channel.
interface-number
(Optional) Interface number.
Defaults
This command has no default settings.
Command Modes
Privileged EXEC
Command History
Usage Guidelines
The valid values for the port number depend on the chassis used.
Examples
This example shows how to display the ACL configuration on the Fast Ethernet interface 6/1:
Switch# show access-group mode interface fa6/1Interface FastEthernet6/1:Access group mode is: mergeSwitch#Related Commands
show adjacency
To display information about the Layer 3 switching adjacency table, use the show adjacency command.
show adjacency [{interface interface-number} | {null interface-number} | {port-channel number} | {vlan vlan-id} | detail | internal | summary]
Syntax Description
Defaults
This command has no default settings.
Command Modes
EXEC
Command History
Usage Guidelines
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 1 to 13, and valid values for the port number are from 1 to 48.
Hardware Layer 3 switching adjacency statistics are updated every 60 seconds.
The following information is contained in the show adjacency command:
•
Protocol interface.
