The first statement enables the use of SNMP on the device as explained previously The next statement introduces the trap group called FEDERICA Establishing trap groups allows SNMP traps to be sent and it is recommended that several trap groups are established depending on the recipient or the type of traps that are sent For example for all traps to be sent to one host a separate trap group should be established The trap group name is a string and will be embedded in the community field The NOC or implemented trap receiver can therefore recognize the SNMP trap as belonging to FEDERICA Within the trap group FEDERICA statements are configured that define which traps should be sent and where they should be sent The configured statements are categories targets and version The categories statement specifies the trap types which the trap group can receive To keep the overhead to a minimum only the type specifically needed should be stated Since the prototype is based on the coldstart trap the only category to be included is startup Version is set to all so coldstart traps of all SNMP versions will be sent and can be identified by the NOC The target statement is obligatory for every trap group that is configured and it specifies the IPv4 or IPv6 address of the recipient s In this prototype the IP address of the trap receiver which should be the NOC is included Besides the three statements a routing instance for example a logical
