How do I delete the configuration on a specified interface of a WLAN device
To delete all configurations on a specified interface of a WLAN device, you need to delete the configurations one by one. For example, if GE0/0/1 works in auto-negotiation mode and automatically negotiates both the rate and the duplex mode, run the following commands to delete corresponding configurations: - Run the undo auto duplex command in the interface view to restore the default duplex mode for the Ethernet electrical interface in auto-negotiation mode. - Run the undo auto speed command in the interface view to restore the default negotiation rate for the Ethernet electrical interface in auto-negotiation mode.

Blocking a specified domain name on the firewall
For V100R001 and V5, you can configure a security policy, set the destination address to a domain name group that contains the list of domain names to be blocked, and set the action to block to block these domain names. You can also configure URL filtering to blacklist the domain names to be blocked so as to block them. For V300R001, you can only configure URL filtering to blacklist the domain names to be blocked so as to block them.

Will the device management be affected if an interface with loop detected is blocked
The blocked interface does not affect device management because the ping and Telnet functions are not affected. Blocking the interface only affect Layer 2 forwarding on the interface because the blocked interface does not learn MAC addresses.

How to specify the configuration file for next startup on a WLAN device
Run the following commands in the user view on a WLAN device (except Fit APs) to specify the configuration file for next startup: - Run the startup system-software command in the user view to specify the system software for next startup. - Run the startup saved-configuration command in the user view to specify the configuration file for next startup. The following takes newbasicsoft.cc (system software for next startup) and vrpcfg.zip (configuration file) as an example: # Specify the system software to be loaded for the next startup. startup system-software newbasicsoft.cc # Specify the configuration file to be loaded for the next startup. startup saved-configuration vrpcfg.zip
