display ipv6 adjacent-table· 3

 

 

NOTE: ·       The adjacency table feature only applies to hardware forwarding, but not software forwarding. ·       The adjacency table feature does not apply to Ethernet networks that use ARP for storing and managing neighbor information. ·       You can only view adjacency tables of tunnel interfaces and POS interfaces. For more information about tunnel interfaces, see Layer 3—IP Services Configuration Guide. For more information about POS interfaces, see Interface Configuration Guide.

 Virtual Circuit Information : N/A

 Link Head Information(IP)   : ff030021

 Link Head Information(MPLS) : ff030281

# Display the IPv4 adjacency table entries in slot 2.

<Sysname> display adjacent-table slot 2

IP Address       Routing Interface     Physical Interface    Type     Slot

1.1.1.1          Pos2/1/3               Pos2/1/3             PPP      2

Table 1 Output description

Field	Description
IP Address	Next hop IP address
Routing Interface	Adjacency table routing interface, namely, outgoing interface in the route forwarding entry.
Physical Interface	Adjacency table physical interface.
Logical Interface	Adjacency table logical interface: An abstract interface that does not correspond to any physical entity and is used for adjacency table implementation.
Service Type	Adjacency table service type.
Action Type	Action to take on the packet that matches the entry, forward or drop
Link Media Type	Link media type, which is related to the link layer protocol used by the outgoing interface. P2P indicates point-to-point, such as the point-to-point protocol (PPP).
Slot	Slot number of the physical device, such as PVC and DLCI.
Virtual Circuit Information	Virtual circuit information of the adjacency table entry
Link Head Information (IP)	Information of the link layer header corresponding to the IPv4 protocol
