extremeEnhDosEnableIpFdb
Module: EXTREME-ENH-DOS-MIB
OID (symbolic): EXTREME-ENH-DOS-MIB::extremeEnhDosEnableIpFdb
OID (numeric): 1.3.6.1.4.1.1916.1.29.1.2
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: The Flag indicates whether Enhanced DOS protection against IPFDB thrashing is enabled or disabled.
What is extremeEnhDosEnableIpFdb?
This read-write flag turns on Enhanced DOS protection against IP forwarding-database (IPFDB) thrashing, defaulting to false. Enabling it protects the switch's IP forwarding table from being churned by an attacker sending traffic for many bogus destination IPs, which would otherwise evict legitimate entries. An admin seeing IPFDB entries flapping under attack would set this to true(1) to engage the protection globally.
