### ES Hello (ciiPacketCountESHellos)

Number of ES Hello PDU frames seen moving in this direction. ESH PDUs are counted at the lowest enabled level: at L1 on L1 or L1L2 circuits; at L2 otherwise.

### LSP (ciiPacketCountLSPs)

Number of IS-IS LSP frames seen moving in this direction at this level.

### CSNP (ciiPacketCountCSNPs)

Number of IS-IS CSNP frames seen moving in this direction at this level.

### PSNP (ciiPacketCountPSNPs)
