AT-S63 Version 2.0.0 Software Release Notes
PN 613-000592 Rev A 3 Allied Telesyn, Inc.
Known Issues
 QoS Policies and Static Multicast Addresses. The behavior of a QoS policy may be
unpredictable if a policy’s egress port has one or more static multicast addresses. (3196)
 Remote management session through an 802.1x authenticator port. It may not be possible to
ping or remotely manage a switch through an authenticator port set to the 802.1x
authentication method and the Multiple Mode. (3451)
Resolved Issues
 MSTP and LACP. The switch did not forward unicast traffic over an LACP trunk while
concurrently running the Multiple Spanning Tree Protocol. This issue has been resolved.
(3336)
 MSTP and SNMP management. Selecting MSTP as the active spanning tree on the switch
through SNMP management disabled spanning tree. This issue has been resolved. If
spanning tree is enabled prior to the selection of MSTP as the active spanning tree, it
remains enabled after MSTP is selected. (3359)
 Power Supply Status. The status of the main power supply in the AT-9424T/GB and
AT-9424Ti/SP switches was erroneously displayed as OFF in the System Hardware Status
window in the menus interface and by the SHOW SYSTEM command. The status of the main
power supply is now displayed correctly. (3347)
 Management ACL. You could not modify entries in the Management ACL from the web
browser interface. The web browser interface now supports modifying Management ACL
entries. (3455)
 Teardrop DoS defense mechanism. The switch did not display a notification message on the
console or send an SNMP trap when it detected or mirrored packets from a possible Teardrop
attack. This issue has been resolved. (3456)
 SFP modules. If you disabled Auto-Negotiation on twisted pair port 23R or 24R or an SFP
module in an AT-9424T/SP switch and manually set the speed, the switch displayed an error
message if you attempted to change the speed again after the port changed status (i.e., an
SFP is removed and the corresponding port 23R or 24R becomes active). This issue has
been resolved. (3482)
 Tagged VLANs and Static Port Trunks. You could not create a static port trunk if the switch
had a tagged VLAN. This issue has been resolved. (3589)
 Egress traffic mirroring across chipsets. The switch did not support egress traffic mirroring
across chipsets. This issue has been resolved. (3590)
 Maximum multicast groups in the web interface. The IGMP Configuration page in the web
browser interface had the wrong range for the maximum number of multicast groups. The
web page now displays the correct range of 1 to 256. (3591)
 Save Config button. The web browser interface did not display the Save Config button after a
change was made to a RADIUS or TACACS+ parameter. The web browser interface now
displays the button. (3246)
 SHOW CONFIG DYN=QOS command. The SHOW CONFIG DYN=QOS command
displayed the weights of the egress queues incorrectly when the QoS scheduling method
was weighted round robin and the weight values were consecutive (e.g., 1, 2, 3, etc.). The
command displayed the values as a range rather than as individual values. The command
now displays the weights of the egress queues as individual values. (3460)
