Test Commands
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 PPP Echo-Test Command

The system provides a mechanism to verify the Point-to-Point Protocol session of a particular subscriber by sending
Link Control Protocol (LCP) packets to the mobile node. This functionality can be extremely useful in determining the
quality of the air link and delays that may occur.
The command has the following syntax:
ppp echo-test { callid call_id | ipaddr ip_address | msid ms_id |
username subscriber_name }
Keyword/Variable
callid call_id
ipaddr ip_address
msid ms_id
username
subscriber_name
The following figure displays a sample of this command‟s output showing a successful PPP echo-test to a subscriber
named user2@aaa.
USERNAME: user2@aaa MSID: 0000012345 CALLID: 001e8481
