DEVICE MANAGEMENT
Note - The current firmware version (AT-S25 v2.0.2) supports atiStackSwitch.mib v1.0.
However, AT-View Plus Device Manager supports atiStackSwitch.mib v2.10. As a result,
the following additional port parameters will appear:
• Port MDIO
• Port HOL Limit
• Port Back Pressure Limit
• Port STP State
These parameters are defined in v2.10 but will return 'noSuchName.' because they do not
exist in v1.0.
Note - The current firmware version does not allow the Port State parameter to be set to
'enabled'. Attempting to do so will result in the error message: "The error occurred with
'Set' operation. Error: bad value." To enable a port, click on the Enable option under the
Port menu.
Note - 4 ports are allotted for each expansion module slot. This means that ports on
expansion modules will always be numbered starting from 25 if inserted in Slot A and
from 29 if inserted in Slot B. As a result, the Detail Info MIB variable window for port
numbers that do not have corresponding physical ports on the expansion module inserted
will display 'noSuchName.' for all parameters.
Enable
Enables the port.
Note - The current firmware version (AT-S25 v2.0.2) supports atiStackSwitch.mib v1.0
while AT-View Plus Device Manager supports atiStackSwitch.mib v2.10. In v1.0, the
Port State parameter has 6 possible states with the enabled state having an ordinal value
of 3. In v2.10, the Port State parameter has only 2 possible states with the enabled state
having an ordinal value of 1. Since AT-View Plus Device Manager continues to use the
ordinal value 3, which does not exist in v2.10, the confirmation message will appear as
"May I set up 'atiStkSwPortState.x.y' to '???(3)'?" However, clicking on the OK button
will still enable the port successfully. This is because the actual Set operation is
performed on the device whose firmware supports v1.0 and thus, recognizes the ordinal
value 3.
Disable
Disables the port.
Port Mirroring
Displays port mirroring parameters and allows configuration of port mirroring state,
source, and destination.
