What is standbyExtEthernetInterfaceSubnetMask?

This read-write object holds the subnet mask for the standby management module's ethernet interface, applicable only to chassis with an installed standby MM. An administrator sets this so the standby MM correctly determines which addresses are local versus requiring the gateway. For example, an admin corrects this subnet mask after finding the standby MM was failing to reach hosts on its own subnet due to a misconfigured mask.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.3.14
snmpwalk -v2c -c public <target> CME-MIB::standbyExtEthernetInterfaceSubnetMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.3.14.1
snmpget -v2c -c public <target> CME-MIB::standbyExtEthernetInterfaceSubnetMask.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.3.14.1 a <value>
