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.
• Type of routing protocol that is configured on the interface.
• Interface address.
• Method of adjacency that was learned.
interface (Optional) Interface type; possible valid values are ethernet, fastethernet,
gigabitethernet, tengigabitethernet, pos, ge-wan, and atm.
interface-number (Optional) Module and port number; see the “Usage Guidelines” section for
valid values.
null
interface-number
(Optional) Specifies the null interface; the valid value is 0.
port-channel
number
(Optional) Specifies the channel interface; valid values are a maximum of
64 values ranging from 1 to 256.
vlan vlan-id (Optional) Specifies the VLAN; valid values are from 1 to 4094.
detail (Optional) Displays the information about the protocol detail and timer.
internal (Optional) Displays the information about the internal data structure.
summary (Optional) Displays a summary of CEF-adjacency information.
