fddimibMACOldDownstreamNbr
Module: FDDI-SMT73-MIB
OID (symbolic): FDDI-SMT73-MIB::fddimibMACOldDownstreamNbr
OID (numeric): 1.3.6.1.2.1.10.15.73.2.2.1.12
Node type: OBJECT-TYPE
Type: FddiMACLongAddressType
Access: read-only
Description: The previous value of the MAC's downstream neighbor's long individual MAC address. It has an initial value of the SMT- Unknown-MAC Address and is only modified as specified by the Neighbor Information Frame protocol (refer to ANSI SMT 7.2.1 and 8.2).
What is fddimibMACOldDownstreamNbr?
Retains the previous value of this MAC's downstream neighbor address, before the latest Neighbor Information Frame update. Like its upstream counterpart, comparing old and current values reveals recent topology changes affecting this MAC.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.15.73.2.2.1.12 snmpwalk -v2c -c public <target> FDDI-SMT73-MIB::fddimibMACOldDownstreamNbr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.10.15.73.2.2.1.12.1 snmpget -v2c -c public <target> FDDI-SMT73-MIB::fddimibMACOldDownstreamNbr.1
