What is nwAppnFwdCtrLenErrMus?

This read-only Counter reports the total number of Message Units received system-wide, across all ports, that contained a length error during the current operational window. This isolates a specific class of malformed-frame problem from address errors or other header errors, helping narrow down root cause. A spike in this counter coinciding with a firmware upgrade on an attached SNA device would point the admin toward that device's frame formatting.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.1.1.10
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdCtrLenErrMus

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.1.1.10.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdCtrLenErrMus.1

SNMPv3 example:

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