hcxEtherStuPrevUpstrmAal5CrcErrs

Module: COM21-HCXETH-MIB

OID (symbolic): COM21-HCXETH-MIB::hcxEtherStuPrevUpstrmAal5CrcErrs

OID (numeric): 1.3.6.1.4.1.1141.2.45.1.1.8

Node type: OBJECT-TYPE

Type: Gauge32

Access: read-only

Description: Contains the number of AAL5 CRC errors related to upstream traffic from the ComPort in the last 15 minute collection period. Each of these errors indicates a dropped Ethernet frame.

What is hcxEtherStuPrevUpstrmAal5CrcErrs?

This read-only Gauge32 counts AAL5 CRC errors related to upstream traffic from this specific ComPort during the previous, completed 15-minute period, again with each error representing a dropped Ethernet frame. It lets an administrator compare a finished interval against the current one to see if a subscriber's ATM-layer error rate is improving or worsening. For example, an operator would compare this previous-period figure to hcxEtherStuCurrUpstrmAal5CrcErrs to determine whether a customer's connection quality is trending better or worse.
