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 request. If the SNMP agent doesn’t 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 seconds (default is 1 second),

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

Setting up Communication Redundancy on your network helps protect critical links against failure, protects

against network loops, and keeps network downtime at a minimum.

The Communication Redundancy function allows 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

feature is particularly important for industrial applications, since it could take several minutes to locate the

disconnected or severed cable. For example, if the EDS-828 is used as a key communications component of a

production line, several minutes of downtime could result in a big loss in production and revenue. The EDS-828

supports three different protocols to support this communication redundancy function—Rapid Spanning

Tree/ Spanning Tree Protocol (IEEE 802.1w/1D), Turbo Ring, and Turbo Ring V2.
