Enable the Web Management Interface

About this task

Enable the web management interface to provide management access to the switch using a web browser.

HTTP and HTTPS, and FTP support both IPv4 and IPv6 addresses, with no difference in functionality or configuration.

Important

To enable HTTP access to the device, you must disable the web server secure-only option. To enable HTTPS access to the device, the web server secure-only option is enabled by default. The TFTP server supports both IPv4 and IPv6 TFTP clients.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Enable the web server:
web-server enable
Important
- The system prompts you to change the admin and read-only user default passwords when you use the web-server enable command to enable the web management interface.
- The default passwords and community strings are documented and well known.
Optional: To disable the secure-only option (for HTTP access), enter:

no web-server secure-only
Configure the username and the access password:

web-server password rwa WORD<1–20>
Enter and confirm your password.
Enable read-only user:

web-server read-only-user enable
Save the configuration:

save config
