The supported channel numbers are not contiguous. If you specify a channel number that is not listed in the preceding table, the following error message appears:
Error: DWDM Channel configuration failed. Channel number 100 is out of configurable range. The channel range for the Optical module in port <port number> is 11 .. 6150.If the optical module in one of the ports in the specified list does not support DWDM, the following error message is displayed:
Error: No TDWDM Optics on port <port number>.If the optical module in one of the ports in the specified port list is not an Extreme supported optical module, the following error message is displayed:
Error: DWDM Channel configuration failed. Optical module is not Extreme Networks certified. For DWDM channel configuration, Extreme Network Certified DWDM module is required.To display the configuration, use the show ports configuration or the show ports information detail command.
The following command configures DWDM channel 21 on a modular port 1:1:
configure port 1:1 dwdm channel 21
