chasControlEthPortSubMask
Module: CHASSIS-MIB
OID (symbolic): CHASSIS-MIB::chasControlEthPortSubMask
OID (numeric): 1.3.6.1.4.1.800.2.1.3.1.1.24
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: The IP network subnet mask of the Ethernet Mgmt. Port.
What is chasControlEthPortSubMask?
This object holds the subnet mask paired with chasControlEthPortIPAddr for the Ethernet management port. Getting this wrong alongside the IP address would prevent the management port from communicating correctly on its local out-of-band subnet, effectively cutting off that access path even though it looks configured. A management port configured with 192.168.100.5 needs a matching subnet mask like 255.255.255.0 for that /24 out-of-band subnet to function correctly.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.800.2.1.3.1.1.24 snmpwalk -v2c -c public <target> CHASSIS-MIB::chasControlEthPortSubMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.800.2.1.3.1.1.24.1 snmpget -v2c -c public <target> CHASSIS-MIB::chasControlEthPortSubMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.800.2.1.3.1.1.24.1 a <value>
