Symptoms

Cannot view hardware DOS drops through SNMP walk due to missing OID for hardware drops.

Impact

The count of attack packets dropped in hardware cannot be retrieved using SNMP.

Conditions

- AFM licensed and provisioned. - Hardware DOS enabled.

Workaround

View the hardware drops stats using the TMSH command. The following is an example: tmsh shows security dos device-config

Fix Information

MIB OID is implemented as follows for all four counters (drops, drops_rate, drops_1m, and drops_1h) - ltmDosAttackDataStatIntDrops - ltmDosAttackDataStatIntDropsRate - ltmDosAttackDataStatIntDrops1m - ltmDosAttackDataStatIntDrops1h
