Enhancements in Release F.05.xx
Clarification of Time Zone Issue
Starting with the F.05.xx version of the switch operating system software, the method of configuring
the Time Zone for TimeP or SNTP configuration has been updated. Previous switch software, for all
HP ProCurve switches, used positive time offset values for time zones that are West of GMT and
negative values for time zones that are East of GMT. The standards indicate that time zones West of
GMT should be designated by negative offset values, and time zones East of GMT by positive values.
Software version F.05.xx updates this configuration method, but if you use the same values for
indicating time zones as you did for previous HP ProCurve switches, the time will be set incorrectly
on your HP ProCurve Switches 2512 and 2524. For example, for previous HP ProCurve switches, the
US Pacific time zone was configured by entering +480. With software version F.05.xx, the US Pacific
time zone must now be configured by entering -480.
Syslog Overview
The switch’s Event Log records switch-level progress, status, and warning messages. The System-
Logging (Syslog) feature provides a means for recording these messages on a remote server. The
Syslog feature complies with RFC 3168. UNIX users know this capability as ’Syslogd’. Using Syslog
you can send Event Log messages from multiple switches to a central location to help investigate
and identify network-level problems. (Refer to Figure 1 below.)

Syslog (Syslogd)capability Adds the ability to direct Event Log messaging to an external file as an aid in
debugging network-level problems. Complies with RFC 3164.

Isolated Port Groups Originally added in release F.04.08 to provide an alternative to VLANs, this
feature now offers two new isolation groups: group1 and group2.

Port-Based Access Control
(802.1x) with Open VLAN Mode
Originally added in release F.04.08 to provide access control through a RADIUS
server, this feature now includes Open VLAN Mode. This gives you a means for
allowing a client computer without 802.1x supplicant software to temporarily
join an unauthorized-client VLAN and proceed with initialization services, such
as acquiring IP addressing, 802.1x supplicant software, and other optional
services you may want to provide.
