lpAruTxFrameFreeListCongestionState

Module: Nortel-Magellan-Passport-AtmBaseMIB

OID (symbolic): Nortel-Magellan-Passport-AtmBaseMIB::lpAruTxFrameFreeListCongestionState

OID (numeric): 1.3.6.1.4.1.562.2.4.1.12.20.100.1.56

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This attribute indicates the congestion state of the transmit frame 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 lpAruTxFrameFreeListCongestionState?

Reports the transmit frame free list's congestion level (0-3) on this ATM-FP: at 3 there is no congestion and all traffic is stored, while at 0 only the highest-priority frames (DP=0) are kept and the rest are discarded before transmit.

Examples
