bigipNetLinkDown

OID (symbolic): F5-BIGIP-COMMON-MIB::bigipNetLinkDown

OID (numeric): 1.3.6.1.4.1.3375.2.4.0.24

Node type: NOTIFICATION-TYPE

Description: An internal interface link is down. This is for L1 and L2. These are internal links within the box connecting the CPU and Switch subsystems, which should never lose link. If they do, it indicates a serious problem.

What is bigipNetLinkDown?

This notification alerts that an internal network link between critical subsystems (CPU and Switch fabric) within an F5 BIG-IP appliance has lost connectivity, indicating a serious hardware problem. Internal links should never fail under normal operation, so this trap signals potential hardware failure or system malfunction. An operator receiving this alert should immediately investigate the appliance and consider failover to a redundant system or hardware replacement.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' F5-BIGIP-COMMON-MIB::bigipNetLinkDown
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.3375.2.4.0.24

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:
