Server load balancing traffic information
Server load balancing traffic information
Server Load Balancing (SLB) is based on associations between real servers and virtual servers.
The real servers are your application servers. The virtual servers have one or more virtual IP
addresses (VIPs). You associate a real server with a virtual server by binding TCP/UDP ports on the
real servers with TCP/UDP ports on the virtual server. When a client sends a TCP/UDP request for a
port on the virtual server, the ServerIron sends the client’s request to the real server.
The following objects provide information on the SLB traffic packets that were transmitted between
the server and the clients.
snL4TcpAge
brcdIp.1.1.4.1.28
Syntax: Integer
Read-write Specifies how many minutes a TCP server connection can remain
inactive before the session times out and the ServerIron disconnects
the session.
Changing the value of this object affects only the new TCP sessions
that are opened after the change is made. Current sessions will use
the maximum age that was specified before the change occurred.
This object globally sets the age for all TCP ports. To override this value
for a port, specify the age locally on the individual port using the
device’s CLI.
Valid values: 2 – 60 minutes
Default value: 30 minutes
snL4UdpAge
brcdIp.1.1.4.1.29
Syntax: Integer
Read-write Specifies how many minutes a UDP server connection can remain
inactive before the session times out and the ServerIron closes the
session.
Changing the value of this object affects only the new UDP sessions
that are opened after the change is made. Current sessions will use
the maximum age that was specified before the change occurred.
This object globally sets the age for all UDP ports. To override this
value for a port, specify the age locally on the individual port using the
device’s CLI.
Valid values: 2 – 60 minutes
Default: 5 minutes
Name, OID, and Syntax Access Description
Name, OID, and Syntax Access Description
snL4slbForwardTraffic
brcdIp.1.1.4.1.6
Syntax: Counter
Read only Shows the number of packets sent by clients to the server.
snL4slbReverseTraffic
brcdIp.1.1.4.1.7
Syntax: Counter
Read only Shows the number of packets sent by servers to clients. Generally, this
value is 0 unless the client is using FTP or another application that
causes the server to initiate connections.
snL4slbDrops
brcdIp.1.1.4.1.8
Syntax: Integer
Read only Shows the total number of packets dropped by the ServerIron. This
statistic includes the following:
• TCP Resets – Resets sent by the ServerIron
• Forward Resets – Resets from the client
• Unsuccessful requests – Requests sent to a TCP or UDP port that
is not bound to the request’s destination VIP.
