Module: COM21-HCXTX-MIB
OID (symbolic): COM21-HCXTX-MIB::hcxStatsCurrMinTxNullCells
OID (numeric): 1.3.6.1.4.1.1141.2.22.2
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: Represents the number of null cells transmitted in the current 15 minute period.
What is hcxStatsCurrMinTxNullCells?
This read-only Gauge32 counts the number of null (idle-filler) cells transmitted on the TX card during the current 15-minute period. A high value here signals the downstream link is running well under its line rate. For example, an admin seeing null cells dominate this counter confirms the TX card is far under capacity, which is consistent with a low reading on hcxDownstreamUtil.
