trkPaUsedLc

Module: Nortel-Magellan-Passport-PorsTrunksMIB

OID (symbolic): Nortel-Magellan-Passport-PorsTrunksMIB::trkPaUsedLc

OID (numeric): 1.3.6.1.4.1.562.2.4.1.60.4.11.1.2

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: This attribute gives the total number of Logical Channels currently busy on the trunk. When this number reaches maxLc, no more paths are allowed to instantiate through this trunk. Note that it is possible for usedLc to be less than maxLc but for there to be no currently free LogicalChannels. This is because a LogicalChannel can be in one of several intermediate states between free and busy.

What is trkPaUsedLc?

The number of Logical Channels currently busy on this trunk; once this reaches the negotiated maxLc, no further paths can be established here, even though a lower usedLc than maxLc doesn't guarantee a free channel due to intermediate channel states.
