PAGE 4
AT-S63 Version 4.0.0 Patch 2 Software Release Notes The management software has a new command line interface based on the commands in the AlliedWare Plus™ operating system found on other Allied Telesis products, such as the Layer 3 switches. If you are already familiar with the commands in the AlliedWare Plus™ operating system, you may find this new interface more convenient to use than the standard command line.

AT-S63 Version 4.0.0 Patch 2 Software Release Notes The 802.1x port-based network access control feature is now fully compliant with the following: — Microsoft Network Access Protocol on Windows Server 2008, Windows Vista, and Windows XP Service Pack 3 — Symantec Network Access Control The commands used to control the MAC address table have a new MODULE parameter that lets you manage the MAC address tables on the individual switches of a stack.
PAGE 6
AT-S63 Version 4.0.0 Patch 2 Software Release Notes The variable n is the current value of the Stack ID parameter in the display. For example, if the current value of the parameter is 1, the command would be: set stack moduleid=1 newmoduleid=auto 4. After entering the command, you need to reset the switch with this command because your change to the switch’s ID assignment does not take affect until the unit is reset: restart reboot 5. After the switch has completed the reset, log on again as the manager.

AT-S63 Version 4.0.0 Patch 2 Software Release Notes AT-9424T Switch AT-9424T Switches shipped after March 2009 and having “04221” in their serial numbers must use Version 4.0.0 or later of the AT-S63 Management Software. Downloading earlier versions of the management software onto these switches causes them to fail during bootup. Serial Number - x04221xxxxxxxxxx Stacking Tips Stack Size The maximum number of switches in a stack varies according to the switch model.

AT-S63 Version 4.0.0 Patch 2 Software Release Notes on the operations of your network in the event the stack stops functioning. This is because the switches that comprise a stack automatically revert to stand-alone operations if a stack experiences a problem. (This isn’t necessary for a switch assigned the stack ID 1 or 2 because it uses the stack configuration file for both stack and standalone operations.) 5. Power off the switch. 6.

AT-S63 Version 4.0.0 Patch 2 Software Release Notes Supplicant and VLAN Associations - The 802.1x port-based network access control feature could move a port to only one VLAN after receiving a VLAN association from a RADIUS server, and ignored future VLAN associations until a port was linked down and up again. PEAP and 802.1x Port-based Network Access - 802.1x Port-based Network Access now supports PEAP. Version 4.0.0 Operational Notes Stacking and IGMP snooping.
PAGE 11
AT-S63 Version 4.0.0 Patch 2 Software Release Notes Port Mirroring. In order for a switch to mirror tagged packets, the VLANs of the packets must exist on a switch. Packets that contain VIDs of nonexistent VLANs are not mirrored. Denial of Service defense mechanisms. The operation of a Denial or Service defense mechanism on the switch might be unpredictable when a defense is assigned to more than one port or when more than one defense is assigned to the same port.
