LISP Debug Commands

debug lisp control-plane all

To turn on all possible debugging messages related to the Locator/ID Separation Protocol (LISP) control plane, use the debug lisp control-plane all command in privileged EXEC mode. To disable debugging output, use the no form of this command.

debug lisp control-plane all

no debug lisp control-plane all


Caution


Because the debug lisp control-plane all command can generate many messages and alter timing in the network node, use it only when instructed by authorized support personnel.



Caution


Debugging output takes priority over other network traffic. The debug lisp control-plane all command generates more output than any other debug lisp control-plane command and can alter timing in the network node. Use of this command can severely diminish router performance or even render it unusable. In virtually all cases, you should use specific debug lisp control-plane commands.

This command can be useful for troubleshooting remote endpoint-identifier (EID) reachability issues when LIG is used as a diagnostic tool.

Examples

The following is sample output from the debug lisp control-plane lig command. In this example the lig self command is used to generate LISP control-plane LIG events:

Router# debug lisp control-plane lig

LISP control plane Internet Groper debugging is on

Router# lig self

Dec 18 08:37:48.921 PST: LISP: LIG 172.16.21.0 Displaying info.

In this example, the lig command is used to verify reachability and locator information for a remote EID:

Router# lig 172.16.12.1

Dec 18 08:38:24.391 PST: LISP: LIG LIG request for IPv4, EIDs 172.16.12.1, count 3.

Dec 18 08:38:24.891 PST: LISP: LIG 172.16.12.1 Displaying info.

In this example, the lig command is used to verify reachability and locator information for a remote EID that is not reachable (LIG fails to return a valid mapping entry):

Router# lig 172.16.2.1

Dec 18 08:39:33.496 PST: LISP: LIG LIG request for IPv4, EIDs 172.16.2.1, count 3.

Usage Guidelines

When a Proxy Ingress Tunnel Router (PITR) is configured to dynamically import IPv4 or IPv6 endpoint identifier (EID) prefixes for use in signaling the LISP control plane to send a Map Request message for EID-to-RLOC mapping resolution, it may be desirable to monitor this dynamic import activity. The debug lisp control-plane rib-route-import command displays events related to LISP control plane route-import activities.

Examples

The following is sample output from the debug lisp control-plane rib-route-import command. In this example, when clear ip lisp route-import is entered, all route-import routes are marked stale, then re-evaluated according to the ip lisp route-import map-cache command, and remaining stale routes removed, as indicated by the debug output.

Usage Guidelines

The debug lisp detail command enables the display of detailed information, when available, by certain LISP debug commands. This command can be useful for troubleshooting many LISP related issue by causing the display of more detailed debugging output.

Examples

The following is sample output from the debug lisp detail command. In this example, the clear ip lisp map-cache command is first issued with the debug debug lisp control-plane events command enabled. The clear ip lisp map-cache command is then repeated after you enter the debug ebug lisp detail command for comparison:

Usage Guidelines

The amount of output displayed by debug commands can be overwhelming, making the task of troubleshooting difficult. This is especially true when debugging is not filtered to match the packets of interest. The debug lisp filter eid command provides a mechanism for reducing the output of the various LISP-related debug commands by matching only on the specified EID-prefix. This command can be useful for troubleshooting any LISP related issue.

Examples

The following is sample output from the debug lisp filter eid command. In this example, a debug LISP filter is set for the EID 172.16.12.1/32, and then the debug lisp control-plane lig command is enabled. The lig command is used for the EID 172.16.12.1, and then repeated for the EID 172.16.8.1 for comparison. As shown, no debug output is displayed in the second case because the EID does not match the filter:

In this example, a debug LISP filter is set for the EID 172.16.12.1/32,

Usage Guidelines

On an LISP Map-Server (MS), the amount of output displayed by debug commands can be overwhelming, making the task of troubleshooting difficult.

ETR (Router-1):

Router-1# show run | include lisp database-mapping

15.1(4)M

This command was integrated into Cisco IOS Release 15.1(4)M.

Usage Guidelines

The debug lisp forwarding state command displays messages related to LISP forwarding module state. LISP forwarding state is dependent on the device role (for example, Ingress Tunnel Router (ITR) or Proxy ITR), locator status bit (LSB) changes, RLOC changes, Alternative Logical Topology (ALT) virtual routing and forwarding (VRF) configuration, and other similar functions. This command can be useful for troubleshooting LISP forwarding-related issues.

Examples

The following is sample output from the debug lisp forwarding state command. In this example, an RLOC is removed, and then added back for a site endpoint identifier (EID):

Router# debug lisp forwarding state

This command can be useful for troubleshooting LISP forwarding-related issues.

Examples
