lcCmMac
Module: LANCITY-MCNS-MIB
OID (symbolic): LANCITY-MCNS-MIB::lcCmMac
OID (numeric): 1.3.6.1.4.1.482.60.2.16.1.2
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-only
Description: The MAC address of the CM to which the index MAC address is connected. For entries learned on the Ethernet side of the CMTS bridge this value will be 00 00 00 00 00 00 which indicates no CM associativity. For a CM MAC entry this value will be the same as the index, that is the MAC address of the CM itself. For a CPE device on the Cable side of the CMTS bridge this value will be the MAC address of the CM to which that CPE device is connected.
What is lcCmMac?
Read-only MAC address of the cable modem associated with a given entry's index address in the CPE-to-CM mapping table. For an entry learned on the CMTS's Ethernet side this reads all-zeros (no CM association); for a CM's own entry it equals the index itself; for a CPE device on the cable side it gives the CM that CPE is riding behind -- letting an operator trace any device back to its serving modem.
