Parameters

Parameter	Description
`show isis database [detailed] [level {1 \| 2}] [lsp-type {node \| pseudonode}] [system-id <IS-IS System ID>]`	Shows the contents of the IS-IS database. You can use these options in any combination or order to control the output: `detailed` Shows the detailed output of each LSP in the IS-IS database. Output includes each known TLV included in each LSP. `level {1 \| 2}` Shows the IS-IS database information only for the specified level. `lsp-type {node \| pseudonode}` Shows LSP packets only of the specified type. Each IS-IS router in the network sends Node LSP packets. Only the Designated Intermediate System (DIS) on each link sends Pseudonode LSP packets and represents the link as a whole. `system-id <IS-IS System ID>` Shows only LSP packets that the IS-IS router with the specified System ID created. Press the Tab key to see the available System IDs.
`show isis errors [<Error Types>]`	Shows a list of each IS-IS error recorded. By default, this command shows each error type. You can specify one of more of these error types: `csnp` - Shows only IS-IS CSNP errors `global` - Shows only IS-IS global errors `hello` - Shows only IS-IS 'Hello' errors `lsp` - Shows only IS-IS LSP errors `protocol` - Shows only IS-IS protocol errors `psnp` - Shows only IS-IS PSNP errors
`export-routemap [level {1 \| 2}]`	Shows all routemaps for IS-IS export policy. See Route Maps - Export and Import. `level {1 \| 2}` Shows the IS-IS database information only for the specified level.
`show isis hostnames`	Shows the database with the mapping between System IDs and Hostnames.
`show isis interfaces [detailed]` `show isis interface <Name of Interface> [detailed]`	Shows the state of the IS-IS interfaces on the router. By default, the output shows a table with commonly-referenced information. If you specify the "`detailed`" option, the output shows all information for the IS-IS interfaces.
`show isis neighbors [detailed]` `show isis neighbor <Neighbor System ID> [detailed]`	Shows the state of the IS-IS neighbors known to the router. By default, the output shows a table with commonly-referenced information. If you specify the "`detailed`" option, the output shows all information for the neighbors.
`show isis packets`	Shows a summary of IS-IS packets this IS-IS routers sent, received, and dropped. The output is sorted by the packet type.
`show isis summary`	Shows a brief summary of the current running state of the IS-IS router.
`show isis topology` `show isis ipv6 topology`	Shows the Shortest Path First tree that IS-IS calculated for each router in the IS-IS network. When the IPv6 Multi-Topology is enabled, use the IPv6 version of this command to see the IPv6 SPF tree.
