hcxStuL2PrevSnapFiltStat
Module: COM21-HCXSTU-MIB
OID (symbolic): COM21-HCXSTU-MIB::hcxStuL2PrevSnapFiltStat
OID (numeric): 1.3.6.1.4.1.1141.2.55.1.1.25
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: Contains the number of SNAP-encoded IEEE 802.3 packets filtered in the previous 15 min collection period.
What is hcxStuL2PrevSnapFiltStat?
This Gauge32 holds the final count of SNAP-encoded IEEE 802.3 packets the STU filtered during the now-closed previous 15-minute collection period. Because this bucket is frozen rather than still accumulating, an admin can compare it directly to the current period's equivalent counter to see whether SNAP-encoded traffic filtering is trending up or down. For example, if hcxStuL2PrevSnapFiltStat jumped sharply compared to the period before it, that establishes a clear before/after baseline for when a SNAP-emitting device appeared on the LAN.
