ciiPacketCountESHellos
Module: CISCO-IETF-ISIS-MIB
OID (symbolic): CISCO-IETF-ISIS-MIB::ciiPacketCountESHellos
OID (numeric): 1.3.6.1.4.1.9.10.118.1.5.3.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of ES Hello PDU frames seen in this direction. ESH PDUs are counted at the lowest enabled level: at L1 on L1 or L1L2 circuits, and at L2 otherwise.
What is ciiPacketCountESHellos?
This is the number of ES Hello PDU frames seen in this direction, with ESH PDUs counted at the lowest enabled level. ESH PDUs are sent by end systems themselves rather than by another intermediate system, and on the same modern IP-only networks this remains a legacy artifact that should stay at zero, useful mainly as a tripwire for unexpected OSI activity. For example, an admin auditing a segment for unexpected legacy protocol chatter would check this counter alongside ciiPacketCountISHellos, expecting both to remain at zero on a pure IP network.
