Information About DWDM
Dense Wavelength-Division Multiplexing (DWDM) multiplexes multiple optical carrier signals on a single optical fiber. DWDM uses different wavelengths to carry various signals.
To establish a DWDM link, both ends of an Inter Switch Link (ISL) need to be connected with DWDM SFPs (small form-factor pluggable) at each end of the link. To identify a DWDM link, DCNM-SAN discovers the connector type on the Fiber Channel (FC) ports. If the ISL link is associated with the FC ports at each end, then the FC port uses DWDM SFP to connect the links.
Cisco DCNM for SAN discovers FC ports with DWDM SFPs and the ISLs associated with the FC ports. The DCNM-SAN Client displays ISL with DWDM attribute on the topology map.
Note The Fabric Shortest Path First (FSPF) database only displays an ISL link, which is connected with DWDM SFPs at both ends.
Configuring X2 DWDM Transceiver Frequency
Restrictions
This feature is supported only in MDS 9134 modules. With MDS 9134 modules, the 10-Gigabit Ethernet ports must be in a down state when you configure the X2 transceiver frequency.
To configure X2 DWDM transceiver frequency for a module, follow these steps:
To configure the X2 DWDM transceiver frequency using Device Manager, follow these steps:
Step 1 From the Device Manager menu bar, select Physical > Modules .
The module configuration window is displayed.
Step 2 Choose an XcvrFrequencyConfig option button.
To configure the X2 DWDM transceiver frequency, follow these steps:
Step 1 From the Physical Attributes pane, select Hardware .
The module configuration window is displayed.
Step 2 Click the Card Module Config tab.
Step 3 In the X2 XcvrFrequencyConfig column, choose an option.
Monitoring DWDM Links
The DCNM-SAN Client displays DWDM links with a “dash-dash” pattern. The tooltip for the link displays “DWDM” to indicate its link type.
To view the DWDM link, follow these steps:
Step 1 Select the switch in the Logical Domain region.
Step 2 Select ISL in the Physical Attribute s region.
The Information pane diplays the ISL’s information.
Step 3 Click the Physical tab.
You see the ISL in the Information pane.
The ISL’s Physical table displays the connector type as sfpDwdm .
Move the mouse over the link to see the tooltip as DWDM indicating the link type.
Step 4 Perform a Dump Discovery of ISL to list all ISLs. DWDM links are listed with [DWDM].
