concNetMask

Module: CRESCENDO-MIB

OID (symbolic): CRESCENDO-MIB::concNetMask

OID (numeric): 1.3.6.1.4.1.203.1.1.1.3

Node type: OBJECT-TYPE

Type: IpAddress

Access: read-write

Description: The concentrator's subnet mask.

What is concNetMask?

This read-write IpAddress is the concentrator's subnet mask. An administrator configures it together with concIpAddr and concBroadcast so the device correctly determines which addresses are local versus routed. For example, mismatching this mask against the actual subnet size would cause the concentrator to miscalculate its broadcast address and potentially miss traffic.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.203.1.1.1.3
snmpwalk -v2c -c public <target> CRESCENDO-MIB::concNetMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.203.1.1.1.3.1
snmpget -v2c -c public <target> CRESCENDO-MIB::concNetMask.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.203.1.1.1.3.1 a <value>
