dpnssSigUnprocessedUIs

Module: DPNSS-MIB

OID (symbolic): DPNSS-MIB::dpnssSigUnprocessedUIs

OID (numeric): 1.3.6.1.2.1.10.999.1.1.15

Node type: OBJECT-TYPE

Description: The number of peer UI frames received on this interface but could not be processed successfully (e.g. due to layer 2 overload). This count gives the unsuccessful UI frame count for on all the DLCs.

What is dpnssSigUnprocessedUIs?

Counts peer UI frames received on this signaling channel that could not be processed successfully, for example due to Layer 2 overload, aggregated across all its DLCs. A rising count here, which also triggers a dpnssMibDLCStatusChange-family trap when it exceeds a threshold, tells an admin the signaling channel is struggling to keep up with incoming Layer 2 traffic.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.999.1.1.15
snmpwalk -v2c -c public <target> DPNSS-MIB::dpnssSigUnprocessedUIs

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.999.1.1.15.1
snmpget -v2c -c public <target> DPNSS-MIB::dpnssSigUnprocessedUIs.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dpnssSigUnprocessedUIs.1
