apexOampSubnetMask

Module: APEX-MIB

OID (symbolic): APEX-MIB::apexOampSubnetMask

OID (numeric): 1.3.6.1.4.1.1166.1.31.6.3.1.1.2

Node type: OBJECT-TYPE

Type: IpAddress

Access: read-write

Description: This is subnet mask of the OAMP IP (Enet1) interface of the APEX. The subnet mask is normally via a BootP when connected to a BootP server. When not connected to a Bootp Server, the Subnet Mask may directly be changed by setting this parameter.

Once written, a save must be performed via the apexSaveConfig parameter and the APEX must be rebooted for the change to take effect.

@Config(config=yes, reboot=yes) @Save(apexSaveConfig, value=2) @File(config.ini, type='ini')

What is apexOampSubnetMask?

Reports or sets the subnet mask for the APEX OAMP Ethernet interface (Enet1). Like the IP address, it can be assigned via BootP or set manually, and requires a configuration save and reboot to apply.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1166.1.31.6.3.1.1.2
snmpwalk -v2c -c public <target> APEX-MIB::apexOampSubnetMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1166.1.31.6.3.1.1.2.1
snmpget -v2c -c public <target> APEX-MIB::apexOampSubnetMask.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1166.1.31.6.3.1.1.2.1 a <value>
