Module: HM2-L2REDUNDANCY-MIB

OID (symbolic): HM2-L2REDUNDANCY-MIB::hm2MrpMRMRoundTripDelayMax

OID (numeric): 1.3.6.1.4.1.248.11.40.1.1.1.1.18

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: The max. Round-Trip-Delay (in microseconds) which was measured by the MRM since startup or reset. A device which supports only the recovery delays 200ms and 500ms doesn't support the measuring of round-trip-delay.

What is hm2MrpMRMRoundTripDelayMax?

The highest round-trip delay, in microseconds, the manager has measured on the ring since startup or the last reset - a way to spot degrading cable or switch performance over time.

Examples
