SUMMARY
Figure 22 DHCP IP Screens
In this configuration, the test set sends a DHCP discovery mes
-
sage to start DHCP negotiation with the ISP and obtain an IP
address. During this process, the following is reported:
ST
: Start time indicates when CONNECT was pressed.
ET
: Elapsed time since CONNECT was pressed.
The status of the connection to the ISP is displayed on the right
side of the screens. It can be DHCP UP, if it has passed, or it can
be DHCP DOWN, if it has failed. The status is also displayed un
-
der the IP STATUS line in the left screen of Figure 22. It can be:
DHCP: in progress
: Connection is not yet completed.
DHCP: PASS
: A successful connection.
DHCP: FAIL
: Connection was not successful as indicated by
one of the following messages:
• LINK DOWN: Link is closed.
• DHCP DISCOVERY FAILED: There is no response to the DHCP
discovery message sent by the STU-R. The reason could be
an incorrect VP/VC or an incorrect protocol.
• DHCP REQUEST FAILED: A DHCP NACK or DHCP DECLINE
message has been sent by the DHCP server.
If DHCP: PASS is displayed, the following is reported:
• LOCAL IP: STU-R IP address assigned by the DHCP server.
