Session
Session
The following objects define TCP and UDP sessions in a ServerIron.
Name, OID, and Syntax Access Description
snL4MaxSessionLimit
brcdIp.1.1.4.1.1
Syntax: Integer Read-write Specifies the maximum number of active sessions the ServerIron
allows. An active session is an entry in the ServerIron session table. A
UDP or TCP session that has become idle but has not yet timed out
(according to the UDP or TCP age timer) is an active session in the
table.
Valid values: 0 - 1,000,000
Default: Depends on the target system configuration
snL4TcpSynLimit
brcdIp.1.1.4.1.2
Syntax: Integer Read-write Shows the maximum number of TCP SYN requests per second per real
server that the ServerIron is allowed to send. A TCP SYN request is a
packet that a client sends to request a TCP connection to the server.
Limiting the number of TCP SYN requests that can be sent to the
server each second protects the ServerIron from TCP SYN attacks.
Valid values: 1 – 65535
Default: 65535
snL4slbGlobalSDAType
brcdIp.1.1.4.1.3
Syntax: Integer Read-write Shows the method the ServerIron uses to select a real server for client
request:
•
leastconnection(1) – The ServerIron sends the request to the real
server that currently has the fewest number of active connections
with clients.
•
roundrobin(2) – The ServerIron sends the request to each server
in rotation, regardless of how many connections each server has.
•
weighted(3) – The ServerIron uses the weights you assign to the
real servers to select a real server. The weights are based on the
number of entries the ServerIron has for each server in the
sessions table.
Default: leastconnection(1)
snL4slbTotalConnections
brcdIp.1.1.4.1.4
Syntax: Counter Read only Shows the total number of client connections on the ServerIron since
its last reboot. A connection consists of two sessions: client-to-server
session and server-to-client session.
snL4slbLimitExceeds
brcdIp.1.1.4.1.5
Syntax: Integer Read only Shows the number of times the TCP SYN requests from clients
exceeded the configured
“snL4TcpSynLimit” value.
snL4FreeSessionCount
brcdIp.1.1.4.1.13
Syntax: Integer Read only Shows the number of sessions that are still available for use. This
number is the maximum number of sessions configured, minus the
number of active sessions.
