linkBeat
Module: KEEPALIVED-MIB
OID (symbolic): KEEPALIVED-MIB::linkBeat
OID (numeric): 1.3.6.1.4.1.9586.100.5.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Indicate which method is used to check if a link is up or down. netlink(1) means that the kernel will push a link state change while polling(2) means that the status of the link is checked periodically.
What is linkBeat?
Which method keepalived uses to detect whether a network interface's link is up or down: netlink means the kernel pushes link-state change events, while polling means keepalived periodically checks the interface status itself. Admins mostly leave this at the default (netlink) since it's more immediate, but might use polling on hardware/drivers with unreliable netlink events.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9586.100.5.1.5 snmpwalk -v2c -c public <target> KEEPALIVED-MIB::linkBeat
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9586.100.5.1.5.1 snmpget -v2c -c public <target> KEEPALIVED-MIB::linkBeat.1
