After successful install of Napatech Driver the TIM Setup UI/Interfaces page shows the Napatech card which is receiving traffic and it has been selected.
However the TIM Setup/Packet Statistics gives an error when trying to be displayed and in the TIM log these error messages for apmpacket are repeated on a regular basis:
**ERROR: hub: ApmPacketComm: timapmpacketcomm:
**ERROR: hub: ApmPacketComm: config client response error from timapmpacketcomm
**ERROR: hub: hubmanager: could not configure apmpacket. Retrying ...
Even after a tim restart from UI or command line ("service tim restart") the problem still remains
APM TIM 9.7, 10.0, 10.1, 10.2
In APM 9.7 and later versions the TIM architecture has been performance enhanced with a separate apmpacket process. That process needs to be reconfigured with the Napatech pcap library and restarted
1. Follow the instructions on the APM 9.7, 10.x wikis to configure the apmpacket configuration file /opt/CA/APM/apmpacket/config/apmpacketsettings.db with the Napatech pcap library
APM Installation and Upgrade - Installing APM TIM Napatech Drivers - Register pcap with TIM
i.e. Step 3 here:
3. Update the apmpacket application as follows:
/opt/CA/APM/tim/bin/configtool -f /opt/CA/APM/apmpacket/config/apmpacketsettings.db -s libpcapPath /opt/napatech3/lib/libpcap.so
2. Then restart the apmpacket process which runs separately from the tim process itself and has a separate service. Restart using:
service apmpacket restart
3. Restart the TIM itself. Confirm that the Packet Statistics page does now show data and the TIM log no longer contains the apmpacket errors.
