Module: CTRON-DHCP-MIB
OID (symbolic): CTRON-DHCP-MIB::ctDhcpIfLeasePeriod
OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.1.2.12.2.2.1.1.11
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This value is the time period for which an IP address assigned by this interface is valid. The units are seconds. A value of 0 signifys that the lease will never expire.
What is ctDhcpIfLeasePeriod?
ctDhcpIfLeasePeriod is a read-write integer giving, in seconds, the time period for which an IP address assigned by this interface remains valid, with a value of 0 meaning the lease never expires. An admin tunes this to balance address reuse against renewal traffic, shortening it on subnets with high device turnover and lengthening it on stable ones. For example, setting ctDhcpIfLeasePeriod to 0 on an interface serving a small set of long-lived servers means those DHCP-assigned addresses never need to be renewed or expire.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.1.2.12.2.2.1.1.11 snmpwalk -v2c -c public <target> CTRON-DHCP-MIB::ctDhcpIfLeasePeriod
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.1.2.12.2.2.1.1.11.1 snmpget -v2c -c public <target> CTRON-DHCP-MIB::ctDhcpIfLeasePeriod.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.1.2.12.2.2.1.1.11.1 i <value>
