Enhanced X2 interface monitoring

In an LTE mobile network, X2 interfaces are used to connect Evolved Node Bs (eNodeBs) for signal handover, monitoring, and radio coverage. SRX Series devices connect these eNodeBs using IPsec tunnels. This feature enables you to monitor traffic between eNodeBs by snooping into the clear text traffic as it flows from one IPsec tunnel to another. Use the monitor-filter statement at the [edit security forwarding-options] hierarchy level to duplicate clear text packets and send them to the physical interface. You can then use Ethereal or other packet analyzers to verify or collect the X2 traffic.
