h3cNATBLConnectHighValue
Module: A3COM-HUAWEI-NAT-MIB
OID (symbolic): A3COM-HUAWEI-NAT-MIB::h3cNATBLConnectHighValue
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.18.1.2.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The maximal connection amount. If the connection amount exceeds the value, the IP address will be added into blacklist. The IP address will not be removed from blacklist until the connection amount is less than the minimal connection amount.
What is h3cNATBLConnectHighValue?
Sets the connection threshold above which a source IP enters the NAT blacklist (integer 20-20000 connections). Security teams configure this to mitigate resource exhaustion attacks by blocking overly-active sources. A threshold of 5000 blocks IPs exceeding 5000 concurrent translated connections.
