cntFddiMACRootConcentratorMac
Module: CNTAU-MIB
OID (symbolic): CNTAU-MIB::cntFddiMACRootConcentratorMac
OID (numeric): 1.3.6.1.4.1.333.1.10.2.2.2.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: A MAC in a concentrator is a root concentrator MAC if its transmit path exits the concentrator via a Port in a peer node; or if the MAC exits via a Port in a tree node and there is no A, B, or S Ports that are active on that MAC's current Path.
What is cntFddiMACRootConcentratorMac?
This value indicates whether this MAC, if it resides in a concentrator, qualifies as the root concentrator MAC based on how its transmit path exits the concentrator relative to peer and tree node ports. An administrator uses this to identify which MAC in a concentrator anchors the dual-ring topology for management and troubleshooting purposes. For example, knowing which MAC is the root concentrator MAC helps the admin predict how a fault on that specific MAC would affect the whole concentrator's ring connectivity.
