Severity: 3-Major


The Link Status traps, both F5 proprietary and standard LinkUp/LinkDown are issued on the BIG-IP hardware but not on BIG-IP Virtual Edition (VE) configurations.


Log messages are issued and SNMP traps are issued if an SNMP trap destination is configured. On BIG-IP Virtual Edition, logs are emitted but traps do not occur. An SNMP client waiting for a Link Status trap on an administrator to enable or disable then, does not receive the trap.


This occurs when interfaces on hardware-based BIG-IP systems or VE-based BIG-IP configurations experience link status events (links go up or down, or are administratively enabled or disabled).
