vwm-shelf
Syntax [no] vwm-shelf vwm-shelf-id [vwm-type vwm-type] [create]
Context config>system
Description Platforms Supported: 7210 SAS-E.
Provides the context to configure the shelf information for 1830 VWM clip-on device.
The user must create the VWM clip-on device and provision the shelf ID to allow the 7210 software
to communicate with the shelf and retrieve information. The value specified in the parameter vwm-
shelf-id must match the shelf ID set using the rotary dial on the clip-on device. If these shelf IDs do
not match, 7210 SAS devices will not be able to interact to the device and does not provide any
information about the device. 7210 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 provides 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, 7210 does not attempt to retrieve information of the
shelves that follow the mis-configured shelf.
The no form of the command removes the configured shelf ID and the software removes all the
information it has for the shelf.
Default No default value is used.
Parameters vwm-shelf-id — The Shelf ID used to identify the 1830 VWM clip-on device attached to 7210.
Values 1-7
vwm-type — Provides the context to configure the shelf type information for 1830 VWM clip-on
device.
Values [ec-cw|ec-dw|ec-dwa]
ec-cw — Identifies the controller card to be of type passive 1830 VWM CWDM controller.
ec-dw — Identifies the controller type to be passive 1830 VWM DWDM controller.
ec-dwa — Identifies the controller type to be active 1830 VWM DWDM controller.
NOTES:
• 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 7210 SAS-E through USB interface through OMC interface,
the main shelf (that is, the first shelf) to which the node is connected should have EC-DWA. If
