the MIB variable window. To see the change reflected in the MIB variable window, the
Mirroring Destination Port parameter should be set to a non-zero value.
Stacking Menu
From the Stacking menu, you can perform enhanced stacking from any AT-8000 Series master
switch.
Stacking Info
Displays information about the switch's mode. This is also the menu where you can
perform enhanced stacking.
Note - For the Stack Switch Model parameter, additional characters appear after the
model name for discovered AT-8524M, AT-9424T/SP and AT-9424T/GB devices.
Expansion Module Notes
• AT-View Plus Device Manager cannot distinguish between the AT-A45/xx, AT-A47, and
AT-STACKM expansion modules. All are displayed with the same GIF image.
• When both the AT-A45 and AT-A46 expansion modules are present on a device, the AT-
A45 port image may show up as green and its Port Speed parameter may reflect the value
"1 Gbps" even if there is no connection established on the port. To reflect the correct port
image color and port speed, restart the device. This applies to the following devices:
AT-8016F/xx
AT-8024M
AT-8088/xx
• The Spanning Tree Protocol (STP) does not work for the AT-A46 expansion module
when it is installed on an AT-8016F/ST device. As a result, the Port State parameter of
the AT-A46 expansion module port will never be set to 'blocking' and the port image will
never turn yellow.
• Connection between an AT-A47 expansion module port that is configured to operate at
1Gbps full duplex and a port on another device can only be established if the port on the
other device is configured to auto-negotiate.
• For the AT-A47 expansion module, AT-View Plus Device Manager will only display the
AT-A45/AT-A47/AT-STACKM shared GIF image if a GBIC module is present in the
GBIC slot.
• By default, the Port Speed and Mode parameter of the AT-A47 expansion module port is
set to 'auto sense'. From this mode, the Port Speed and Mode can only be changed to
'1Gbps full-duplex'. However, once set to '1Gbps full-duplex', it can no longer be set to
'auto sense'.
