IPv4 adjacency table commands
Use this feature to check the adjacency entries on tunnel interfaces. For information about tunnel interfaces, see "Configuring tunneling."
display adjacent-table
Use display adjacent-table to display IPv4 adjacency entries.
Syntax
In standalone mode:
display adjacent-table { all | physical-interface interface-type interface-number | routing-interface interface-type interface-number | slot slot-number } [ count | verbose ]
In IRF mode:
display adjacent-table { all | physical-interface interface-type interface-number | routing-interface interface-type interface-number | chassis chassis-number slot slot-number } [ count | verbose ]

Parameters
all: Displays all IPv4 adjacency entries.
physical-interface interface-type interface-number: Displays IPv4 adjacency entries for the specified physical interface.
routing-interface interface-type interface-number: Displays IPv4 adjacency entries for the specified routing interface.
slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays IPv4 adjacency entries for all cards. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device or specifies a PEX. The chassis-number argument represents the member ID of the IRF member device or the virtual chassis number of the PEX. The slot-number argument represents the slot number of the card or PEX. On an IRF fabric, this command displays IPv4 adjacency entries for all cards if you do not specify a card. On an IRF 3 system, this command displays IPv4 adjacency entries for all cards and PEXs if you do not specify a card or PEX. (In IRF mode.)
count: Displays the number of IPv4 adjacency entries.
verbose: Displays detailed information about IPv4 adjacency entries.

Table 1 Command output
|
Field |
Description |
|
IP address |
IP address of the next hop. · For a P2P link, the IP address of the next hop is not needed. This field displays 0.0.0.0. · For an NBMA link, the value 0.0.0.0 indicates the default adjacency entry. Packets are forwarded through the default virtual circuit. |
|
Routing interface |
Output interface of the matching route entry. |
|
Physical interface |
Physical interface of which the outgoing packets are sent out. |
|
Logical interface |
Logical interface for sending the packets. If the entry has no logical interface, this field displays N/A. |
|
Service type/Type |
Link layer protocol type, such as Tunnel. |
|
Action type |
Packet processing type, Forwarding or Drop. |
|
Link media type |
Link media type: · P2P—Point-to-point link. · NBMA—Non-broadcast multi-access link. |
|
Slot |
ID of the slot that holds the card. |
|
Cpu |
Number of the CPU. |
|
VPN index |
Index of the VPN. |
|
Virtual circuit information |
Information about the virtual circuit, such as PVC or DLCI. If the entry has no virtual circuit, this field displays N/A. |
|
Link head information(IP) |
Link layer header for IPv4. |
|
Link head information(MPLS) |
Link layer header for MPLS. |
IPv6 adjacency table commands
Use this feature to check the adjacency entries on tunnel interfaces. For information about tunnel interfaces, see "Configuring tunneling."
display ipv6 adjacent-table
Use display ipv6 adjacent-table to display IPv6 adjacency entries.
Syntax
In standalone mode:
display ipv6 adjacent-table { all | physical-interface interface-type interface-number | routing-interface interface-type interface-number | slot slot-number } [ count | verbose ]
In IRF mode:
display ipv6 adjacent-table { all | physical-interface interface-type interface-number | routing-interface interface-type interface-number | chassis chassis-number slot slot-number } [ count | verbose ]
