tcpKAInterval
Module: SYS-MIB
OID (symbolic): SYS-MIB::tcpKAInterval
OID (numeric): 1.3.6.1.4.1.1978.2.18.5.17
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The interval of time, expressed in seconds between keepalive packets. Keepalive packets are generated when there is no other socket traffic. Although the operation of keepalive is defined on a per socket basis (see autif.mib), this parameter is global for all TCP applications. (default=30)
What is tcpKAInterval?
Sets the interval, in seconds (default 30), between TCP keepalive packets sent when a connection has no other traffic; like tcpRetransAttempts, this applies globally to all TCP applications even though keepalive itself is enabled per socket.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1978.2.18.5.17 snmpwalk -v2c -c public <target> SYS-MIB::tcpKAInterval
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1978.2.18.5.17.1 snmpget -v2c -c public <target> SYS-MIB::tcpKAInterval.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1978.2.18.5.17.1 i <value>
