Managing Automatic Remote Configuration Download<br />

Overview<br />

File Servers and Download Process<br />

The download process from the file servers is as follows:<br />

1 The username required to connect to the FTP/SFTP enabled servers is provided in the instruction file.<br />

The password required to connect to the servers is same as the username.<br />

2 The required files mentioned in the instruction file are downloaded from the primary FTP/SFTP file<br />

server.<br />

3 If the configuration, debug and script file names are specified in the instruction file, then they are<br />

downloaded to the /flash/working directory of the switch.<br />

4 The Remote Configuration Manager now compares the current firmware version on the switch to the<br />

one mentioned in the instruction file. If the firmware version is different, then firmware upgrade is<br />

performed.<br />

5 The new firmware or image files are downloaded to the working directory of the switch.<br />

Note. If the primary server is down or if there is any failure in downloading the files from the primary file<br />

server, then a connection is established with the secondary file server. The secondary file server is used for<br />

file download.<br />

6 All the required files are downloaded.<br />

Note. If a specific filename (for firmware and configuration/debug/script files) is not found, an error is<br />

logged. The download process continues with the next available file. File transfer is tried three times and<br />

if file transfer still fails, an error is logged, and download process is stopped. In such instances, the<br />

working folder of the switch will contain an incomplete set of image files, configuration, debug, or script<br />

files. For details on troubleshooting under such instances, see - “Nearest-Edge Mode Operation” on<br />

page 12-17<br />

7 Now, the DHCP client configured on the related VLAN is removed.<br />

8 The script file is downloaded and the commands in the script file are run. All the commands in the<br />

script file are implemented on the switch in the order specified.<br />

For other detailed steps that are part of the automatic remote configuration download process, see<br />

“Automatic Remote Configuration Download Process” on page 12-9<br />

LED Status<br />

The LED status during different stages of the Automatic Remote Configuration download process is as<br />

follows:<br />

• DHCP phase: OK1 LED is flashing green<br />

• DHCP lease obtained: OK1 LED is solid green<br />

• DHCP phase stopped by console login: OK1 LED is solid green.<br />
