Cisco Cisco Unity Express for SRE Troubleshooting Guide
One situation wherein the network administrator must troubleshoot the RBCP messages between the
CUE module and the router is when the interface configuration has been verified, but you still cannot
ping the CUE module. First, check the status of the interface and ensure that the interface and line
protocol are up, as shown in this example.

Router# show interfaces service−engine 1/0
Service−Engine1/0 is up, line protocol is up
Hardware is I82559FE, address is 0003.b912.xxxx (cia 0001.b912.xxxx)
Interface is unnumbered. Using address of FastEthernet0/0 (a.3.6.29)
Next, verify the RBCP state machine status on the router, as shown in this example. The CUE module
must be in a steady state for proper operation.

If you are still unable to ping the CUE module IP address, troubleshoot the RBCP messages
exchanged between the CUE module and the host router. You will see Switch Communication
Protocol (SCP) messages. scp−tx indicate messages that the router transmits to the CUE module
whereas scp−rx indicates messages that the CUE transmits to the router.
You can use these two tables in order to decode the values.
