System Management
The user must create the VWM clip-on device and provision the shelf ID to allow the
7210 SAS software to communicate with the shelf and retrieve information. The value
specified in the vwm-shelf-id parameter must match the shelf ID set using the rotary dial on
the clip-on device. If these shelf IDs do not match, the 7210 SAS devices will not be able to
interact to the device and does not provide any information about the device. 7210 SAS
software cannot detect a mismatch between the value of the configured vwm-shelf-id and the
shelf ID set on the rotary dial.
A fixed number of 1830 VWM devices can be managed by the 7210 SAS devices. The limit
depends on the interface used to connect to the 1830 device. The user must provision all the
shelves that are connected to the 7210 SAS device.
The vmw-type enables the context to configure the shelf type information for 1830 VWM clip-
on device. The user must provision the shelf-type of the connected 1830 device. The software
uses this information to match with the shelf-type retrieved from the device and raise a trap/
event when there is a mismatch and marks the shelf as operationally down. Additionally, in a
cascaded configuration, if there is a mismatch in provisioning of the shelf, the 7210 SAS does
not attempt to retrieve information of the shelves that follow the mis-configured shelf.
The no form of this command removes the configured shelf ID and the software removes all
the information it has for the shelf.
Parameters vwm-shelf-id — Specifies the 1830 VWM clip-on device attached to 7210 SAS device.
vwm-type — Specifies the shelf type information for 1830 VWM clip-on device.
ec-cw — Specifies the controller card to be of type passive 1830 VWM CWDM controller.
ec-dw — Specifies the controller type to be passive 1830 VWM DWDM controller.
ec-dwa — Specifies the controller type to be active 1830 VWM DWDM controller.
Note:
create — Keyword to create the vwm-shelf-id.

Values 1 to 7
Values ec-cw, ec-dw, ec-dwa
• The vwm-shelf-id can take values in the range 1 to 7. This implies that the rotary switch
on the connected optical clip-on device must be set to a value in this range.
• For management of DWDM using the 7210 SAS-M, 7210 SAS-T, 7210 SAS-R6 and
7210 SAS-R12 through OMC interface, the main shelf (that is, the first shelf) to which
the node is connected should have EC-DWA. If connected through OMC interface, the
shelf ID can be 1 to 7 and if connected through USB interface, the shelf ID should be 0.
• If the main shelf has any other shelf ID (that is, 1 to 7), the shelf will not become
operational.
