Usage Guidelines

To check statistics about received IS-IS purge LSPs carrying the POI TLV, run the display isis purge packet command. You can specify packet-number in the command to check statistics about a specified number of purge LSPs, and the maximum value of packet-number is 20. If its value is set to 20:

The first two displayed purge LSPs are sent by the local source system, with fragment number 0, one of which is Level-1, and the other is Level-2.
The first 10 displayed purge LSPs are generated locally, and the next 10 purge LSPs are from neighbors. The purge LSPs are displayed in reverse order of the time when they were received. If the LSP ID is followed by an asterisk (*), the purge LSP is generated locally.
