The first command limits new TCP connections to the real server to 1000 per second. The second
command limits the rate of new UDP connections to the real server to 800 per second.
Syntax: max-tcp-conn-rate num
Syntax: max-udp-conn-rate num
The num variable specifies the maximum number of connections per second. There is no default.
The maximum connection rate that can be configured is 4294967295.
To limit the rate of new connections for a specific application port, enter commands such as the
following.
Virtual ADX(config-rs-RS1)#port http
Virtual ADX(config-rs-RS1)#port http max-tcp-conn-rate 600
These commands add port HTTP (80) to the real server and limit the rate of new connections to the
port to 600.
Syntax: port TCP/UDP-portnum max-tcp-conn-rate num
Syntax: port TCP/UDP-portnum max-udp-conn-rate num
The TCP/UDP-portnum variable specifies the application port.
The num variable specifies the maximum number of connections per second. The maximum
connection rate that can be configured is 4294967295.
Configuring the maximum connection rate for a virtual server
You can specify the maximum allowed TCP or UDP connection rate for virtual servers. The Brocade
Virtual ADX monitors the traffic conditions and rejects new connections when the connection rate
exceeds the limit.
To limit the number of new TCP or UDP connections that a virtual server can receive each second,
use the max-tcp-conn-rate or max-udp-conn-rate command, respectively.
Virtual ADX(config)# server virtual-name-or-ip vs2 200.1.1.2
Virtual ADX(config-vs-vs2)# max-tcp-conn-rate 2000
Virtual ADX(config-rs-vs2)# max-udp-conn-rate 800
The first command limits new TCP connections to the server to 2000 per second. The second
command limits the rate of new UDP connections to the server to 800 per second.
Syntax: max-tcp-conn-rate num
Syntax: max-udp-conn-rate num
The num variable specifies the maximum number of connections per second. There is no default.
Enter a number from 1 to 4294967295.
You can display the VIP TCP connection rate (tcp-conn-rate) and UDP connection rate
(udp-conn-rate) by using the show server virtual command.
