lpAruTxCellFreeListCongestionState
Module: Nortel-Magellan-Passport-AtmBaseMIB
OID (symbolic): Nortel-Magellan-Passport-AtmBaseMIB::lpAruTxCellFreeListCongestionState
OID (numeric): 1.3.6.1.4.1.562.2.4.1.12.20.100.1.26
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This attribute indicates the congestion state of the transmit cell free list on this ATM-FP.
The congestion state of a free list is indicated by a numeric value ranging from 0 to 3. When a free list is in a congested state x, only traffic with discard priority (DP) 0 to x will be stored. Traffic with DP > x will be discarded.
Therefore, if the congestion state is 3, there is no congestion and all traffic is stored. Likewise, when the congestion state is 0, there is maximum congestion and only traffic with DP=0 will be stored.
What is lpAruTxCellFreeListCongestionState?
Reports the transmit cell free list's congestion level as a number 0-3: at state 3 there is no congestion and all traffic is stored, while at state 0 only cells with the lowest discard priority (DP=0) are kept and everything else is dropped before transmit. An admin watching this can tell how aggressively the FP is shedding lower-priority ATM traffic.
