The echo-interval command is used in conjunction with the
and
commands as described in this chapter.
In addition to receiving an echo response for this echo protocol, if we receive a GTPP Node Alive Request
message or a GTPP Echo Request message from a presumed dead CGF server, we will immediately assume
the server is active again.
The alive/dead status of the CGFs is used by the AAA Managers to affect the sending of CDRs to the CGFs.
If all CGFs are dead, the AAA Managers will still send CDRs, (refer to the

albeit at a slower rate than if a CGF were alive. Also, AAA Managers independently determine if CGFs are
