" ::= { siaeMib 85 } -------------------------------------------------------------------------------- -- llf GROUP -------------------------------------------------------------------------------- -- -- This group is used for Link Loss Forwarding configuration and alarm reporting -- -- Each physical interface (LAN) can be assigned to a LLF circuit in order to -- propagate its LOS alarm through a radio link. -- -- For each radio link, there are several circuits. -- Each interface can insert into a circuit its LOS alarm to be propagate to the -- other endpoint of a radio link. -- In each directions, the circuit has an signal failure if at least the -- operative status of one LAN connected to the circuit is down (LOS). -- In the local terminal, a LAN interface uses the signal failure of the circuit -- to propagate the LOS alarm by turning off physical level. -- -- In order to propagate in both direction a LOS to an interface, a SNMP manager -- must (in both link terminals): -- 1) Create an entry in llfTable with index equal to the ifIndex of interface. -- 2) Attach this entry to a circuit creating an entry in llfMapTable. -- 3) Insert the LOS alarm in the circuit setting llfMapLosInsertion to -- enable. -- -------------------------------------------------------------------------------- ------ Beginning -------------------------------------------------------------- llfMibVersion OBJECT-TYPE SYNTAX INTEGER MAX-ACCESS read-only STATUS current DESCRIPTION "Numerical version of this module.
