# Monitoring IS-IS

The CLI has commands available for monitoring IS-IS parameters and CLNS parameters.

## System Event Logs

To troubleshoot and monitor IP, use the following system event logs:

- isisAdjChange—IS-IS adjacency up or down events
- isisAdjPackets—IS-IS adjacency hello packets
- isisBfdEvents—IS-IS interactions with BFD
- isisChecksumErr—IS-IS checksum errors
- isisGeneral—IS-IS system notifications
- isisHelloGeneral—IS-IS system notifications
- isisHelloPackets—IS-IS hello packets
- isisipv6Log—IS-IS IPv6 notifications
- isisLdpEvents—IS-IS interactions with LDP
- isisLocalUpdate—IS-IS local LSP packets
- isisMplsTeAdvertisements—IS-IS MPLS traffic engineering advertisements
- isisMplsTeEvents—IS-IS MPLS traffic engineering
- isisNsfEvents—IS-IS nonstop forwarding events during warm starts
- isisProtocolErr—IS-IS protocol errors
- isisSnpPackets—IS-IS complete sequence numbers PDU (CSNP) and partial sequence numbers PDU (PSNP) packets
- isisSpfEvents—IS-IS Shortest Path First (SPF)
- isisSpfStatistics—IS-IS SPF timing and statistic data
- isisSpfTriggers—IS-IS SPF triggering
- isisUpdate Packets—IS-IS LSP packets sent or received

For more information about using event logs, see the JUNOSe System Event Logging Reference Guide.

## Monitoring IS-IS Parameters

You can monitor the IS-IS link-state database and IS-IS debug information. Use the commands in this section to:

- Display router information.
- Display information about SPF calculations.
- Monitor IS-IS summary address information.
- Display debug information.
- Display host.
- Display information about MPLS tunnels.
- Clear adjacencies.
- Display paths to intermediate systems.
- Display information about the settings for IS-IS graceful restart.

You can use the output filtering feature of the show command to include or exclude lines of output based on a text string you specify. See JUNOSe System Basics Configuration Guide, for details.

clear isis adjacency

- Use to remove entries from the adjacency database.
- Specify a hostname or the system ID of a neighbor to clear only adjacencies with that neighbor.
- Specify no options to remove all adjacencies from the database.
- Example
  `
  host1#clear isis adjacency
  `
- There is no no version.
- See clear isis adjacency

debug isis

- Use to obtain debug-related information about certain parameters.
- This command manipulates the same log as the Global Configuration log commands.
- You can select from these parameters:
  - adj-packets—IS-IS adjacency-related packets
  - mpls traffic-eng advertisements—MPLS traffic-engineering agent advertisements
  - mpls traffic-eng agents—MPLS traffic-engineering agents
  - snp-packets—IS-IS CSNP/PSNP packets
  - spf-events —IS-IS Shortest Path First events
  - spf-statistics—IS-IS SPF timing and statistic data
  - spf-triggers—IS-IS SPF triggering events
  - update-packets—IS-IS update-related packets
- Example
  `
  host1#debug isis adj-packets
  `
- Use the no version to disable debugging display.
- See debug isis

## Displaying CLNS

You can display the following information related to the CLNS protocol:

- CLNS information about interfaces
- Information about router adjacencies
- Information about ES and IS neighbors
- Protocol-specific information for each routing process
- Information about CLNS packets
- Global CLNS configurations

You can set a statistics baseline for CLNS using the baseline clns command.

baseline clns

- Use to set a statistics baseline for CLNS.
- The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
- Use the optional interface-specifier parameter to specify an interface; otherwise the command sets a baseline for all interfaces.
- You cannot set a baseline for groups of interfaces.
- When baselining is requested, the time since the last baseline was set is displayed in days, hours, minutes, and seconds.
- Use the optional delta keyword with the show clns traffic command to specify that baselined statistics are to be shown.
- Example

      host1#show clns traffic detail
