Module: CTRON-APPN-MIB

OID (symbolic): CTRON-APPN-MIB::nwAppnFwdLsCtrHdrErrBlus

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.2.1.1.12

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: Specifies the total number of received Basic Link Unit (BLU)s during nwAppnFwdLsCtrOperationalTime which have length errors on the link for which this entry exists.

What is nwAppnFwdLsCtrHdrErrBlus?

This read-only Counter tracks, per its source description, the total number of received BLUs during the current nwAppnFwdLsCtrOperationalTime window that had length errors on the APPN link for which the entry exists. It gives an administrator a way to spot a specific link that is delivering malformed traffic, distinct from an overall drop in throughput. If this counter climbs on one particular APPN trunk while others stay flat, that isolates the length-error problem to a single physical link rather than the whole router.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.2.1.1.12
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdLsCtrHdrErrBlus

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.2.1.1.12.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdLsCtrHdrErrBlus.1
