pending traps are sent. For permanent-on links (e.g. LANs), “disabled” is the recommended setting. For other
links “enabled” is the recommended setting.
• Trap verify receiver: Here the IP address of the receiver, verifying the link, can be entered. In many cases, it
might be one of the trap receiver addresses as entered in 0. However, in dial-up links, optionally the IP address
of a receiving modem (e.g. ISDN router) could be used instead of the IP address of a real trap receiver.
• Timeout: A timeout time between 30 and 600 seconds might be specified, in order to detect a link error. The
NEC-E is waiting the specified time for replies on the “sysDescr” SNMP Get Requests. After this time all
pending traps are sent, regardless of a reply has arrived or not. Important: In this case of timeout the “traps sent”
and the “traps discarded” counter (see below) are incremented.
• Trap Accumulation Time: It is possible to collect traps during the “Trap accumulation time”, which can be set
between 0 and 60 seconds, until they are transmitted all together. This feature helps to reduce connection fees in
dial up connections. In the following cases the accumulated traps are in any case released for sending:
• The internal trap memory is 3/4 filled.
• The SNMP agent of the NEC-E is polled by any kind of manager.
• Test “trap verify receiver” response: This function is very useful to set up and test the communication in modem
links. By clicking this link it can be tested, whether the “Trap Verify Receiver” is answering correctly on the
SNMP Get Request. (Timeout after 30 seconds). This link is only visible, when “Verify before Trap” is enabled.
