h3cMACInformationRemovedMACNum
Module: A3COM-HUAWEI-MAC-INFORMATION-MIB
OID (symbolic): A3COM-HUAWEI-MAC-INFORMATION-MIB::h3cMACInformationRemovedMACNum
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.87.1.1.4
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of MAC addresses that removed by the device since the h3cMACInformationEnabled is set to enabled(1) and h3cMACRemovedEnable is set to enabled(1) at least on one interface. If the h3cMACInformationEnabled is set to disabled(2), the object will always return 0.
What is h3cMACInformationRemovedMACNum?
This counter tallies the total number of MAC addresses removed from the device's MAC table since monitoring started. It indicates aging or port down events and helps operators detect churn in network topology. A rising value signals frequent device disconnections or ARP/MAC instability.
