b) Re-negotiation Failure
The lease time must be regularly re-negotiated (except if the IP address has
been offered by a BOOTP server).
If a re-negotiation fails the following dialog box is displayed:
WARNING: DHCP REBINDING TOO LONG
The AX3000 could be disconnected in 2 minutes
Please log-off before automatic shutdown
Press <F11> to clear this message
This indicates that in two minutes the AX3000 will be no longer be permitted to
use the leased IP address and the session will be terminated
If after these two minutes, the re-negotiation has still failed, the following dialog
box is displayed:
DHCP REBINDING FAILED
Please contact your network administrator
Press <F11> to reboot
All current sessions (telnet, tty, lpd, etc.) will have been closed (i.e. lost).
Note: the AX3000 Trace Mode allows a trace of data exchanged between the
AX3000 and the DHCP server (see Chapter 3.1). This is useful to diagnose
problems.
A.4 - THE DNS PROTOCOL
The DNS protocol (Domain Name System) allows names to be 'resolved' by the
AX3000. Resolving is retrieving an IP address associated with a name.
