Usage Guidelines

You must globally enable DHCP snooping by using the ip dhcp snooping global configuration

command for any DHCP snooping configuration to take effect.

When the option-82 feature is enabled, the default remote-ID suboption is the switch MAC address. This

command allows you to configure either the switch hostname or a string of up to 63 ASCII characters

(but no spaces) to be the remote ID.

If the hostname exceeds 63 characters, it is truncated to 63 characters in the remote-ID configuration.

This example shows how to configure the option-82 remote-ID suboption:

Switch(config)# ip dhcp snooping information option format remote-id hostname

You can verify your settings by entering the show ip dhcp snooping user EXEC command.
