nwAppnFwdLsBlockNum

Module: CTRON-APPN-MIB

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

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.1.1.1.33

Node type: OBJECT-TYPE

Type: DisplayString

Access: read-write

Description: This represents the 3 hexadecimal digit block number which precedes the 5 digit id number in the 8 digit node id of the adjacent node. The node id is used in XIDs and Alerts. The block number identifies the product type. Both the block number and id number combined, uniquely identify the adjacent node within the installation network.

What is nwAppnFwdLsBlockNum?

This read-write 3-character string holds the hexadecimal block number that, with the id number, forms the adjacent node's 8-digit node id used in XIDs and Alerts, identifying that node's product type. An admin configures this to match the actual product type of the equipment at the far end of this link so XID exchange and Alert reporting correctly identify it. An admin linking to a specific model of remote controller would set this block number to that model's documented product-type code.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.1.1.1.33
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdLsBlockNum

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.1.1.1.33.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdLsBlockNum.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.1.1.1.33.1 s <value>
