AT-S62 Version 1.4.0 Software Release Notes
PN: 613-000490 Rev. A 3 Allied Telesyn, Inc.
AT-S62 Version 1.4.0
New Features
 Fan control. This new feature for the AT-8524POE switch automatically adjusts the speed of
the unit’s cooling fans based on the ambient temperature of the room or wiring closet where
the unit is installed and the load requirements of the PoE devices connected to the ports on
the device. This feature is adjusted from the System Configuration menu in the menus inter-
face and the SET SYSTEM FANCONTROL command in the command line interface. This
feature is not supported in the web browser interface. The default setting for this feature is
disabled.
 Quality of Service. The following new parameters have been added to Quality of Service flow
groups, traffic classes, and policies:
- ToS parameter for replacing the Type of Service field of IPv4 packets.
- Move ToS to Priority parameter for replacing the value in the 802.1p priority field with the
value in the ToS priority field in IPv4 packets.
- Move Priority to ToS parameter for replacing the value in the ToS priority field with the
802.1p priority field in IPv4 packets.
- Send to Mirror Port parameter for copying traffic to a destination mirror port. (QoS policies
only.)
The new parameters are adjustable from the menus and command line interfaces, but not the
web browser interface.
 802.1x port-based network access control. The following new features have been added to
authenticator ports:
- MAC address-based authentication as an alternative to 802.1x username and password
authentication.
- Supplicant mode for controlling the number of supplicants who can log on to an
authenticator port.
- Guest VLAN parameter that permits an authenticator port to be a member of a designated
VLAN when no supplicant is logged on.
- VLAN assignment and secure VLAN parameters that allow for dynamic VLAN assignments
from a RADIUS authentication server for supplicant accounts.
The new parameters are configured from the Configure Authenticator Port Access Parame-
ters menu in the menus interface and the SET PORTACCESS|PORTAUTH PORT
ROLE=AUTHENTICATOR command in the command line interface. They can also be config-
ured from the Authenticator Parameters page in the web browser interface.
 Unknown multicast packet filtering feature. This feature discards all unknown ingress multi-
cast packets on a port. It can improve switch performance in situations where a multicast
stream arrives on a port of a switch where there are no host nodes. The feature is set through
the Port Configuration menu in the menus interface and the SET SWITCH PORT command
in the command line interface. This feature can also be set through the Port Configuration
window in the web browser interface. (The menu location and command for this feature were
stated incorrectly in the software release notes for AT-S62 Version 1.3.0 Patch 01.)
 SNMP community strings. The maximum length of an SNMP community string has been
increased to 32 characters from 14 characters. (Backward compatibility is provided in the
