ctDs0ifInDiscards
Module: CT-DS0ent-MIB
OID (symbolic): CT-DS0ent-MIB::ctDs0ifInDiscards
OID (numeric): 1.3.6.1.4.1.52.4497.20.2.1.13
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of inbound packets which were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.
What is ctDs0ifInDiscards?
This read-only Counter counts inbound packets that were discarded even though no errors were detected, for example to free up buffer space. An admin monitors this for a sign of buffer exhaustion or congestion on a DS0 channel rather than an actual line-quality problem. For example, a climbing ctDs0ifInDiscards count alongside otherwise clean ctDs0ifInErrors suggests the channel is being overwhelmed by traffic volume rather than experiencing physical errors.
