lntFddiPortOpticalSwitchExist

Module: MODULES-MIB

OID (symbolic): MODULES-MIB::lntFddiPortOpticalSwitchExist

OID (numeric): 1.3.6.1.4.1.81.25.1.1.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This attribute describes the presence of the optical switch and for existing optical switches describes the possibility of the auto-reconfiguration of path resources in the case of power fault.

What is lntFddiPortOpticalSwitchExist?

Reports whether this FDDI port has an optical bypass switch installed, which would allow the ring to automatically reconfigure around the port in the event of a power failure; exist(1) tells the admin this port has that extra resilience hardware, while not-exist(2) means a power loss at this node could actually break the ring.
