What is standbyDhcpSubnetMask?
This read-only object reports the subnet mask assigned to the standby management module's ethernet interface by the DHCP server, applicable only to chassis with an installed standby MM. An administrator checks this to confirm DHCP handed the standby MM the correct subnet mask for its network segment. For example, an admin verifies this DHCP-assigned subnet mask matches the rest of the management VLAN before troubleshooting standby MM connectivity issues.
