rtgDpnLpStatsDiscardLpCongested

Module: Nortel-Magellan-Passport-DpnRoutingMIB

OID (symbolic): Nortel-Magellan-Passport-DpnRoutingMIB::rtgDpnLpStatsDiscardLpCongested

OID (numeric): 1.3.6.1.4.1.562.2.4.1.40.4.6.10.1.8

Node type: OBJECT-TYPE

Type: PassportCounter64

Access: read-only

Description: This attribute counts the packets that have been discarded by DPN packet forwarding, on the entire module, due to congestion on this LP. This value is the sum of the packets discarded by all LPs due to insufficient shared memory on this one. Note that DPRS packets leaving the network at this module are not counted. The counter wraps to zero when the maximum value is exceeded.

What is rtgDpnLpStatsDiscardLpCongested?

Would count packets discarded module-wide by DPN packet forwarding due to congestion on this particular Link Processor (LP) running low on shared memory, but this table is marked not implemented in the MIB. Where implemented, it would help pinpoint which LP is the source of forwarding drops seen in rtgDpnDiscardLpCongested.

Examples
