Description: The number of NETBIOS_NR_ex (NetBIOS Name Recognized-explorer) messages received on this transport connection.

What is dlswTConnOperNRexRcvds?

This counter tallies the number of NetBIOS Name Recognized (NR_ex) messages received over this Data Link Switching transport connection. DLSw operators use this to monitor the frequency of NetBIOS name resolution traffic flowing through the tunnel. High rates may indicate excessive name lookups or network reconnaissance activity on the legacy network.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.46.1.2.3.1.32
snmpwalk -v2c -c public <target> DLSW-MIB::dlswTConnOperNRexRcvds

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.46.1.2.3.1.32.1
snmpget -v2c -c public <target> DLSW-MIB::dlswTConnOperNRexRcvds.1
