IKS-6726 Featured Functions

SNMP Inform Mode
SNMPv2 provides an inform mechanism. When an inform message is sent from the SNMP agent to the NMS, the
receiver sends a response to the sender acknowledging receipt of the event. This behavior is similar to that of
the get and set requests. If the SNMP agent does not receive a response from the NMS for a period of time, the
agent will resend the trap to the NMS agent. The maximum timeout time is 300 sec (default is 1 sec), and the
maximum number of retries is 99 times (default is 1 time). When the SNMP agent receives acknowledgement
from the NMS, it will stop resending the inform messages.

Using Communication Redundancy
Communication redundancy on your network helps protect critical links against failure, protects against
network loops, and keeps network downtime at a minimum.
Communication redundancy functions allow the user to set up redundant loops in the network to provide a
backup data transmission route in the event that a cable is inadvertently disconnected or damaged. This is a
particularly important feature for industrial applications, since it could take several minutes to locate the
disconnected or severed cable. For example, if the IKS-6726 is used as a key communications component of a
production line, several minutes of downtime can result in a big loss in production and revenue. The IKS-6726
supports three different protocols for communication redundancy—Rapid Spanning Tree Protocol
(IEEE-802.1w) and Turbo Ring, and Turbo Ring V2.
When configuring a redundant ring, all switches on the same ring must be configured using the same
redundancy protocol. You cannot mix the Turbo Ring, Turbo Ring V2, and STP/RSTP protocols within a ring. The
