Output Fields

Table 1 describes the output fields for the show isis database command. Output fields are listed in the approximate order in which they appear. Fields that contain internal IS-IS information useful only in troubleshooting obscure problems are not described in the table. For more details about these fields, contact your customer support representative.

Table 1: show isis database Output Fields

Field Name	Field Description	Level of Output
Interface name	Name of the interface on which the LSP has been received; always IS-IS for this command.	All levels
level	Level of intermediate system: 1—Intermediate system routes within an area; when the destination is outside an area, it routes toward a Level 2 system. 2—Intermediate system routes between areas and toward other ASs.	All levels
LSP ID	Link-state PDU identifier.	All levels
Sequence	Sequence number of the link-state PDU.	All levels
Checksum	Checksum value of the link-state PDU.	All levels
Lifetime (secs)	Remaining lifetime of the link-state PDU, in seconds.	All levels
Attributes	Attributes of the specified database: L1, L2, Overload, or Attached (L1 only).	none brief
# LSPs	Total number of LSPs in the specified link-state database.	none brief
IP prefix	Prefix advertised by this link-state PDU.	detail extensive
IS neighbor	IS-IS neighbor of the advertising system.	detail extensive
ES neighbor	(J Series routers only) An ES-IS neighbor of the advertising system.	detail extensive
IP prefix	IPv4 prefix advertised by this link-state PDU.	detail extensive
V6 prefix	IPv6 prefix advertised by this link-state PDU.	detail extensive
Metric	Metric of the prefix or neighbor.	detail extensive
Header	LSP ID—Link state PDU identifier of the header. Length—Header length. Allocated Length—Amount of length available for the header. Router ID—Address of the local routing device. Remaining Lifetime—Remaining lifetime of the link-state PDU, in seconds.	extensive
Packet	LSP ID—The identifier for the link-state packet. Length—Packet length. Lifetime—Remaining lifetime, in seconds. Checksum—The checksum of the LSP. Sequence—The sequence number of the LSP. Every time the LSP is updated, this number increments. Attributes—Packet attributes. NLPID—Network layer protocol identifier. Fixed length—Specifies the set length for the packet.	extensive
TLVs	Area Address—Area addresses that the routing device can reach. Speaks—Supported routing protocols. IP router id—ID of the routing device (usually the IP address). IP address—IPv4 address. Hostname—Assigned name of the routing device. IP prefix—IP prefix of the routing device. Metric—IS-IS metric that measures the cost of the adjacency between the originating routing device and the advertised routing device. IP extended prefix—Extended IP prefix of the routing device. IS neighbor—Directly attached neighbor’s name and metric. IS extended neighbor—Directly attached neighbor’s name, metric, and IP address.	extensive
