Enhancements in Release F.02.02
CDP (Updated by Software Version F.05.50)
CDP (Updated by Software Version F.05.50)
Software version F.02.02 for the Series 2500 switches, implemented CDP-v1 (Cisco Discovery 
Protocol, version 1) to help discover devices in a network. Software version F.05.50 and beyond 
updates this network discovery method to the industry standard Link Layer Discovery Protocol 
(LLDP). For release notes describing the latest software updates for your switch model, visit the 
ProCurve Networking website at

New Time Synchronization Protocol Options
Using time synchronization ensures a uniform time among interoperating devices. This helps you to 
manage and troubleshoot switch operation by attaching meaningful time data to event and error 
messages. 
Formerly, TimeP was the only time protocol available for time synchronization in Series 2500 
switches. Beginning with software release F.02.02, the switches also offer SNTP (Simple Network 
Time Protocol) and a new 
timesync
 command for changing the time protocol selection (or turning off 
time protocol operation).
N o t e s
Although you can create and save configurations for both time protocols without conflicts, 
the switch allows only one active time protocol at any time.
Time synchronization is no longer active in the factory default configuration. You must first 
select the desired protocol (default: TimeP), and then enable it.
In the factory-default configuration for release F.02.02 and later, the time synchronization 
method is set to TimeP, with actual TimeP operation disabled. (In earlier releases, TimeP 
was enabled with DHCP for acquiring a TimeP server address). 
If you configure SNTP operation in the switch, but later download a configuration created 
using a pre-F.02.02 version of the software, the SNTP configuration will be replaced by the 
non-SNTP time synchronization settings in the downloaded configuration file.
In the menu interface, the time protocol parameters have been moved from the "Internet (IP) 
Service" screen to the "System Information" screen, and the menu path is now:
