Session
The following table contains object that define a session in a ServerIron device.
Hot standby
Hot standby redundancy is a backup feature that allows a ServerIron device to serve as an
automatic backup for another ServerIron device. Each hot-standby pair consists of two ServerIron
devices. One ServerIron device serves as the primary or active ServerIron device, and the other
serves as the secondary or standby ServerIron device. The standby ServerIron device becomes
active only if the primary ServerIron device fails due to loss of power or loss of data path. The active
and standby ServerIron devices must have the same SLB or TCS configuration and share the same
virtual MAC address. The shared MAC address can be selected from the available pool on either
the active ServerIron device or the standby ServerIron device.
The following objects apply to the hot standby redundancy feature.
snL4slbDrops

This statistic includes the following:
•
TCP Resets – Resets sent by the ServerIron device.
•
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.

they were sent by a client to a VIP port that is bound to a disabled real
server port.
snL4slbAged
brcdIp.1.1.4.1.11
Syntax: Integer Read-only Shows the total number of TCP and UDP sessions that have been aged
out and closed. A session ages out when the age timer configured on
the ServerIron device expires.
snL4slbFinished
brcdIp.1.1.4.1.12
