We have a backup interface (dialer2) and we want it to generate a SNMP trap regarding it UP status as soon as it comes up. We tried to change SNMP timeout and queue length but that did not help. Also we cannot specify source interface of SNMP traps in the configuration. How do we make backup interface to generate a trap as soon as it comes up regarding its own UP status and send it to TRAP receiver? Is there any timer that we can fine tune?
