Global TCP/UDP Parameters
TCP-age
The number of minutes the Brocade Virtual ADX allows a TCP connection
to remain unused before closing the connection. The default is 30. To
change this parameter, refer to
The value shown here is the global value. You can override this value for
an individual TCP/UDP port by modifying its port profile. Refer to
“Overriding the global TCP or UDP age”
UDP-age
The number of minutes the Brocade Virtual ADX allows a UDP
connection to remain unused before closing the connection. The default
is 5. To change this parameter, refer to
page 239.
The value shown here is the global value. You can override this value for
an individual TCP/UDP port by modifying its port profile. Refer to
“Overriding the global TCP or UDP age”
Sticky-age
The number of minutes a sticky server connection can remain inactive
before aging out. The default is 5.
TCP-syn-limit
The maximum number of TCP SYN connections per second the Brocade
Virtual ADX is allowed to send to the real server. The default is 65535.
You can guard against TCP SYN attacks by changing this parameter to a
lower value. Refer to
“Limiting the maximum number of TCP SYN
TCP Connections Counters
TCP-total conn
The total number of TCP connections the Brocade Virtual ADX is
currently managing.
Unsuccessful conn
The number of client requests for a TCP port that the Brocade Virtual
ADX could not fulfill because the server was busy or down, or because
the port was not configured on the server.
ICMP Message Feature State
ICMP-message
The state of the ICMP message feature. The state can be one of the
following:
•
Disabled – The Brocade Virtual ADX does not send ICMP
“Destination Unreachable” messages to a client that requests an
HTTP port that is on a busy or down server or that is not configured
on the server. This is the default.
•
Enabled – The Brocade Virtual ADX sends ICMP “Destination
Unreachable” messages to clients when the requested HTTP port is
not available or not configured.
To change the state of this feature, refer to
Unreachable or Destination Unreachable messages”
