rptrAddrTrackSourceAddrChanges
Module: RFC1516-MIB
OID (symbolic): RFC1516-MIB::rptrAddrTrackSourceAddrChanges
OID (numeric): 1.3.6.1.2.1.22.3.3.1.1.4
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This counter is incremented by one for each time that the rptrAddrTrackLastSourceAddress attribute for this port has changed.
This may indicate whether a link is connected to a single DTE or another multi-user segment.
The approximate minimum time for rollover of this counter is 81 hours.
What is rptrAddrTrackSourceAddrChanges?
Counts how many times the last-seen source MAC address on this port has changed, with a minimum rollover time around 81 hours. A port whose count stays near zero likely has a single dedicated device attached, while a rapidly climbing count suggests it's connected to a shared segment or hub with multiple end stations.
