In the event that an issue was discovered with an installed application or line card, depending on the severity, it may be necessary to take corrective action.
The system provides several redundancy and fail-over mechanisms to address issues with application and line cards in order to minimize system downtime and data loss. These mechanisms are described in the sections that follow.
Using the eGTPC Test Echo Command
This command tests the eGTP service's ability to exchange eGTPC packets with the specified peer which can be useful for troubleshooting and/or monitoring.
The test is performed by the system sending eGTP-C echo request messages to the specified peer(s) and waiting for a response.
This command must be executed from within the context in which at least one eGTP service is configured.
egtpc test echo peer-address peer_ip_address src-address egtp_svc_ip_address
|peer-address peer_ip_address||Specifies that eGTP-C echo requests will be sent to a specific peer (HSS).ip_address is the address of the HSS receiving the requests.|
|src-address egtp_svc_ip_address||Specifies the IP address of a S6a interface configured on the
system in eGTP service.
NOTE: The IP address of the system's S6a interface must be bound to a configured eGTP service prior to executing this command.
