Port Mirroring
Displays port mirroring parameters and allows configuration of port mirroring state,
source, and destination.
Note - Valid MIB Set values for the Mirroring Destination Port parameter should
range from 0 to 24. However, the current firmware version allows the user to enter
values up to 65535. Attempting to enter values greater than 65535 will cause the
new value to be converted to its equivalent wrap-around value; i.e., 65536 will
become 0, 65537 will become 1, and so on.
Note - The current firmware version does not allow the Port Mirroring Status
parameter to be set to 'receive' and 'transmit'. Attempting to do so will result in the
error message: "The error occurred with 'Set' operation. Error: bad value".
Note - By default, the Port Mirroring Status parameter is set to 'disabled' and the
Mirroring Destination Port parameter is set to 0. From this default state, the Port
Mirroring Status parameter can be set to 'both' successfully. However, to set the
Port Mirroring Status parameter back to 'disabled', the Mirroring Destination Port
parameter must be set to a non-zero value.
Note - Any change made to the Mirroring Source Ports parameter while the
Mirroring Destination Port parameter is set to 0 will take effect internally but will
not be reflected in 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

Device Manager cannot distinguish between the AT-A45/xx, AT-A47, and AT-
STACKM expansion modules. All are displayed with the same GIF image.
