Quidway V100R006C00 Configuration Manual - 1.1 Overview

1.1 Overview

This section describes the functions, application scenarios, and terms of Auto-Config.

When a new switch or a switch without any configuration file is powered on, Auto-Config runs

automatically to obtain a configuration file. With the Auto-Config function, the network

administrator can manage new switches or switches without any configuration file remotely.

NOTE

The Auto-Config function is applicable to new switches or switches without any configuration file

(unconfigured switches).

The Auto-Config function has the following advantages:

l

The maintenance personnel do not need to manually configure each switch. With this

function, a few maintenance personnel can maintenance widely deployed devices.

l

Auto-Config simplifies the network configurations and implements unified management

and remote debugging on switches.

l

With Auto-Config allows switches to automatically download corresponding configuration

files, reducing the workload of network administrators.

Intermediate File

The intermediate file 

lswnet.cfg

 is used in the Auto-Config process. The intermediate file records

the mapping between MAC addresses of switches and names of configuration files. After an

unconfigured switch obtains the IP address of the FTP/TFTP server, it downloads the

lswnet.cfg

 file from the FTP/TFTP server to search for the name of the required configuration

file, and then downloads the configuration file from the FTP/TFTP server.

NOTE

Auto-Config uses Option 67 to obtain the configuration file first. If Option 67 is not configured, Auto-

Config obtains the intermediate file.

For example, if the MAC address of an S6700 is 0018-82C5-AA89 and the S6700 needs to

download the configuration file S6700.cfg, the contents of the intermediate file are as follows:

mac=0018-82C5-

AA89;vrpfile=V100R006C00.cc;vrpver=V100R006C00;cfgfile=S6700.cfg;patchfile=S6700-

pat.pat;

esn=0213778899;vrpfile=V100R006C00.cc;vrpver=V100R006C00;cfgfile=S6700.

cfg;patchfile=S6700-pat.pat;

NOTE

If the configuration file is located on the FTP or TFTP server, its extension must be 

.cfg

.

A MAC address and a configuration file name are separated by a semicolon. The format of a MAC address

is xxxx-xxxx-xxxx-xxxx. The name of a configuration file contains up to 48 characters, including the

extension 

.cfg

. The name is case insensitive and cannot contain special characters. It is recommended that

the name consists of English letters, numbers, and underscore (_).

If multiple unconfigured switches need to be configured, each row in the intermediate file records the MAC

address of a switch and the name of the configuration file that the switch requires.

Option 67

The Option 67 field is configured on the DHCP server to specify the configuration file.
