What is cucsEtherSwitchIntFIoMacAddr?

This is the MAC address burned into or assigned to this internal FI-to-IOM fabric port. Because internal fabric ports aren't visible to normal network discovery tools, this MAC is mainly useful for correlating this port's hardware identity against internal fabric neighbor data when diagnosing which physical link a given frame or fault actually traversed. Matching this address against a corresponding entry in the fabric's internal neighbor table confirms which of two redundant internal links carried a burst of traffic.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.16.13.1.37
snmpwalk -v2c -c public <target> CISCO-UNIFIED-COMPUTING-ETHER-MIB::cucsEtherSwitchIntFIoMacAddr

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.16.13.1.37.1
snmpget -v2c -c public <target> CISCO-UNIFIED-COMPUTING-ETHER-MIB::cucsEtherSwitchIntFIoMacAddr.1
