Is network proximity part of the enhanced feature set?
A. Network proximity features are not part of the enhanced feature set and require an additional license. If you try to issue proximity commands on the CSS without the appropriate license, you receive this error message: CSS50-1(config)#proximity db 0 tier1 ^ %% Invalid License to execute command. This command belongs to the Proximity Database. Refer to the user manual or contact Cisco Systems, Inc for further information concerning license keys. In order to purchase a license, see your local Cisco reseller. If you purchased a license and need a replacement, send an email to licensing@cisco.com.
