Freezing a port enables you to "lock" it so that no one can accidentally
reconfigure sensitive attributes such as port authentication or default role
settings. For example, if a port is frozen and the administrator
later assigns a default role to the entire device, the frozen port will not receive the new default role. To
reconfigure a frozen port, you must clear its frozen status, do the configuration, then
freeze it again. One application
of this feature would be to prevent interswitch link ports from being accidentally reconfigured.
You can tell if a port is frozen or not by looking at the port icon (frozen port
icons have "icicles" on them) or by checking the Frozen Status on the
port's General tab.
The Frozen Port feature is a software feature available in Policy Manager and some
other NetSight products. It does not freeze the ports in the switch
firmware itself, but protects the user from making configuration changes to
sensitive ports using the software application. Therefore, setting a port
to be "frozen" in one NetSight application will not automatically set
the port to be "frozen" in another NetSight application.
You can freeze ports as part of the general port configuration process in the
Port Configuration Wizard, or you can
freeze or clear frozen ports on an individual or selected port
basis.
You cannot terminate sessions on frozen ports.
Instructions on:
To freeze or clear a single port:
The quickest way to freeze a single port or clear it is to select the port in the left panel and use the
right mouse button menu Set/Clear Frozen option.
- In the left panel, select the Network Elements tab.
- Double-click the device on which the port you want to freeze or unfreeze is located.
- Right-click the port you want to freeze or unfreeze, and select Set/Clear
Frozen. If the port was frozen, it will be unfrozen. If it was unfrozen, it will
be frozen.
You can also freeze a port
or clear a port's frozen state on the port's
General tab.
To freeze or clear multiple ports:
You can freeze multiple ports
or clear them by selecting a device or port group in the left
panel and holding down the Shift or Control key while selecting the ports in the right
panel.
- In the left panel, select the Network Elements tab.
- Select the device or port group in which the ports you want
to freeze or unfreeze are located.
- In the right panel Details View tab, hold down the Shift key (to select a sequence of ports)
or the Control key (to select several ports not in sequence) and select
the ports you want to freeze or unfreeze.
- From the menu bar, select Tools > Set Frozen or Tools > Clear Frozen.
You can freeze all the ports on a single device or clear them by selecting the device and using the
right mouse button menu Set Frozen or Clear Frozen option.
To freeze or unfreeze an entire device:
- In the left panel, select the Network Elements tab.
- Right-click the device whose ports you want to freeze or unfreeze.
- To freeze all the device's ports, select Set Frozen. To unfreeze
all the device's ports, select Clear Frozen.
