nwAppnSysIdNum

Module: CTRON-APPN-MIB

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

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.26

Node type: OBJECT-TYPE

Type: DisplayString

Access: read-write

Description: This represents the 5 hexadecimal digit id number which follows the 3 digit block number in the 8 digit node id used in XIDs and Alerts. The id number uniquely identifies this instance of APPN Routing Services within a product type indicated by the block number. Both the block number and id number combined, uniquely identify this instance of APPN Routing Services within the installation network.

What is nwAppnSysIdNum?

This read-write 5-character string holds the hexadecimal id number that follows the block number in the node's 8-digit node id, uniquely identifying this instance within its product type. Combined with nwAppnSysBlockNum it must be unique across the installation network so XIDs and Alerts can unambiguously identify this specific node. An admin deploying a second router of the same model would assign it a different id number here so the two devices aren't confused in Alert records.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.26
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnSysIdNum

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.26.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnSysIdNum.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.26.1 s <value>
