AT-S63 Version 4.0.0 Patch 2 Software Release Notes

PN 613-001166 Rev A 8 Allied Telesis, Inc.

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 stand-

alone operations.)

5. Power off the switch.

6. Cable the switch to the other switches in the stack as explained in “Cabling the

AT-StackXG Stacking Modules.”

7. To monitor the progress of the discovery process, connect a terminal to the Terminal Port

on the master switch.

8. Log in and configure the parameter settings on the new member of the stack.

9. To add additional members to the stack, repeat this procedure. You should add only one

switch at a time to an stack and should verify that the stack is functioning properly before

adding another switch.

Note:

Adding or removing members from a stack will be disruptive to the operations of your network

because the switches do not forward traffic during the discovery process.

 802.1x port-based network access control. A stack does not support MAC address-based

authentication.

 Stack table sizes. The sizes of the MAC, ARP, and VLAN tables in a stack are:

— 16k MAC Addresses

— 2k ARP Entries

— 4094 VLANs

Version 4.0.0 Known Issues

 Slow Management Sessions with Large Stack - Remote Telnet, SSH, and web browser

management sessions may be slow when a stack has a large number of switches and when

the remote management station is communicating with a stack through a member switch

rather than a master switch. To avoid this problem, try to conduct your remote management

sessions from remote workstations that are communicating directly with a master switch. This

issue affects management traffic only and does not affect the switching or the routing

functions of a stack.

 Enhanced Stacking Through the Web Browser Windows. The enhanced stacking feature is

not supported through the web browser windows on the AT-9424Ts, AT-9424Ts/XP, and

AT-9448Ts/XP Switches, but is supported through the standard command line interface and

the menus. (5871, 6467)

 SNTP Settings. The switch does not retain the SNTP settings. You have to reenter the

settings when you reset or power cycle the unit. (6475)

 802.1x Control Direction parameter. The Control Direction parameter for 802.1x authenticator

ports has an Ingress option for forwarding egress broadcast and multicast traffic when the

ports are in the unauthorized state. This option is nonfunctional and instead blocks these

packets. (5487)
