Persistence; Configuration Guidelines For Auto-Init And Manual Mode - Nokia 7210 Configuration Manual

Boot Options

4.3 Persistence

Optionally, the BOF persist parameter can specify whether the system should
preserve system indexes when a save command is executed. During a subsequent
boot, the index file is read along with the configuration file. As a result, a number of
system indexes are preserved between reboots, including the interface index. If
persistence is not required and the configuration file is successfully processed, the
system becomes operational. If persistence is required, a matching x.ndx file must
be located and successfully processed before the system can become operational.
Matching files (configuration and index files) must have the same filename prefix
such as test123.cfg and test123.ndx, and are created at the same time when a save
command is executed. The persistence option must be enabled to deploy the
Network Management System (NMS). The default is off.
Traps, logs, and console messages are generated if problems occur and SNMP
shuts down for all SNMP gets and sets; however, traps are issued.
4.4 Configuration Guidelines for Auto-init and
This section describes the configuration guidelines for the auto-init and manual
modes.

Manual Mode
• The Ethernet management port does not support auto-init mode. The use of
DHCP to obtain the BOF from the network and other system parameters is
currently not supported on Ethernet management ports.
• In auto-init mode, DHCP requests sent out by the node are in two formats. The
system attempts to communicate with the DHCP server in these two formats,
one after another (if necessary).
- Initially, the DHCP requests are sent out with a priority VLAN tag (VLAN ID
= 0, dot1p PCP bits set to 7).
- If no response is received from the DHCP server after the DHCP request is
sent, DHCP requests are sent without VLAN tags (that is, null-tagged
packets).
• In auto-init mode, the BOF can be downloaded through FTP or TFTP based on
the information a client receives from the DHCP server. The DHCP client tries
the following options to obtain the BOF name and the server IP address:
- using the vendor-specific option
