h3cNATBLConnectHighRate

Module: A3COM-HUAWEI-NAT-MIB

OID (symbolic): A3COM-HUAWEI-NAT-MIB::h3cNATBLConnectHighRate

OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.18.1.2.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The maximal connection rate(in second). If the connection rate exceed the value, the IP address will be added into blacklist. The IP address will not be removed from blacklist until the connection rate is less than the minimal connection rate.

What is h3cNATBLConnectHighRate?

This integer (20 to 21,474,836) specifies the maximum connection rate in connections per second that triggers automatic IP blacklisting. When a source IP exceeds this rate, the NAT device adds it to the blacklist to protect the network from connection floods. Setting this to 5,000 means any IP exceeding 5,000 new connections per second gets blacklisted until its rate drops below the low threshold.
