rptrPortNumberofMACAddressChanges
Module: INTEL-EXPRESS110-MIB
OID (symbolic): INTEL-EXPRESS110-MIB::rptrPortNumberofMACAddressChanges
OID (numeric): 1.3.6.1.4.1.343.2.2.1.14.1.18
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of times that the value of rptrPortLastMACAddress has changed. The typical value for this port is 1, meaning the value of rptrPortLastMACAddress changed from all zeros to a MAC address. A high number of changes indicates a port connected to a switch or bridge.
(RFC2108 rptrAddrTrackSourceAddrChanges)
What is rptrPortNumberofMACAddressChanges?
Counts how many times rptrPortLastMACAddress has changed value on this port, per RFC2108's rptrAddrTrackSourceAddrChanges; a typical end-station port shows 1 (going from all-zeros to a real MAC). A high count indicates the port is actually connected to a switch or bridge aggregating multiple devices rather than a single host.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.343.2.2.1.14.1.18 snmpwalk -v2c -c public <target> INTEL-EXPRESS110-MIB::rptrPortNumberofMACAddressChanges
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.343.2.2.1.14.1.18.1 snmpget -v2c -c public <target> INTEL-EXPRESS110-MIB::rptrPortNumberofMACAddressChanges.1
