hwPimRpMappingChangeCount
Module: HUAWEI-PIM-STD-MIB
OID (symbolic): HUAWEI-PIM-STD-MIB::hwPimRpMappingChangeCount
OID (numeric): 1.3.6.1.4.1.2011.5.25.149.4.1.44
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of changes to active RP mappings on this device.
Information about active RP mappings is available in hwPimGroupMappingTable. Only changes to active mappings cause this counter to be incremented. That is, changes that modify the hwPimGroupMappingEntry with the highest precedence for a group (lowest value of hwPimGroupMappingPrecedence).
Such changes may result from manual configuration of this device, or from automatic RP mapping discovery methods including the PIM Bootstrap Router (BSR) mechanism.
Discontinuities in the value of this counter can occur at re-initialization of the management system, for example when the device is rebooted.
What is hwPimRpMappingChangeCount?
Read-only counter of how many times the active (highest-precedence) RP mapping for some group has changed on this device, whether from manual configuration or automatic discovery such as the PIM Bootstrap Router mechanism; a rising count signals RP-mapping instability that can cause multicast traffic to briefly reroute. Discontinuities can occur across a reboot/reinitialization.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2011.5.25.149.4.1.44 snmpwalk -v2c -c public <target> HUAWEI-PIM-STD-MIB::hwPimRpMappingChangeCount
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2011.5.25.149.4.1.44.1 snmpget -v2c -c public <target> HUAWEI-PIM-STD-MIB::hwPimRpMappingChangeCount.1
