Table 3-82 explains the output fields.
 
Table 3-82: show isis interface 
Field
Description
IFNAME is up, line protocol is up/down
Whether the interface is up or down
Routing Protocol
“IS-IS” and the name that identifies the IS-IS instance.
Network Type
Broadcast
Point-to-Point
Loopback
Circuit Type
Whether the interface is configured for:
Local routing: level-1
Area routing: level 2
Local and area routing: level-1-2
Local circuit ID
Local circuit identifier assigned when interface is created. Each IS-IS interface is assigned a circuit identifier to identify the interface within the link-state database.
If the interface is attached to a multiaccess network, the circuit ID is concatenated with the system ID of the designated IS. This is called the pseudonode ID.
Extended Local circuit ID
Interface index.
Local SNPA
SubNetwork Point of Attachment: for broadcast networks, MAC address.
IP interface address
IPv4 addresses assigned to IS-IS interface.
IPv6 interface address
IPv6 addresses assigned to IS-IS interface.
LDP-ISIS Sync Configured
LDP IS-IS synchronization is enabled.
Holddown timer
Delay for notifications of LDP convergence to IS-IS
Remaining time
Remaining LDP convergence hold time in seconds.
Holddown timer not configured
The LDP convergence holddown timer has not been set.
Level-1 Metric
Interface metric value; used for SPF calculation.
Priority
Priority for designated IS election.
Circuit ID
Unique ID assigned to a circuit internally.
Number of active level-1 adjacencies
Number of adjacencies formed with a neighboring router.
Level-1 LSP MTU
Maximum transmission unit: maximum transmission size for a packet on this interface.
Level-2 Metric
Interface metric value; used for SPF calculation.
Priority
Priority for designated IS election.
Circuit ID
Unique ID assigned to a circuit internally.
Number of active level-2 adjacencies
Number of adjacencies formed with a neighboring router.
Level-2 LSP MTU
Maximum transmission unit: maximum transmission size for a packet on this interface.
Next IS-IS LAN Level-1 Hello
For broadcast networks, when the next IS hello will be sent on this interface.
Next IS-IS LAN Level-2 Hello
For broadcast networks, when the next IS hello will be sent on this interface.
Next IS-IS Hello in
For point-to-point networks, when the next IS hello will be sent on this interface.
