cTapMIBActive
Module: CISCO-TAP-MIB
OID (symbolic): CISCO-TAP-MIB::cTapMIBActive
OID (numeric): 1.3.6.1.4.1.9.9.252.0.1
Node type: NOTIFICATION-TYPE
Description: This Notification is sent when an intercepting router or switch is first capable of intercepting a packet corresponding to a configured data stream. If the configured data stream is an IP one, the value of the corresponding cTapStreamIpStatus is included in this notification. If the configured data stream is an IEEE 802 one, the value of the corresponding cTapStream802Status is included in this notification.
This notification may be generated in conjunction with the intercept application, which is designed to expect the notification to be sent as reliably as possible, e.g., through the use of a finite number of retransmissions until acknowledged, as and when such mechanisms are available; for example, with SNMPv3, this would be an InformRequest. Filter installation can take a long period of time, during which call progress may be delayed.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' CISCO-TAP-MIB::cTapMIBActive snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.252.0.1
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:60835->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (217580963) 25 days, 4:23:29.63 SNMPv2-MIB::snmpTrapOID.0 = OID: CISCO-TAP-MIB::cTapMIBActive
