This feature has the following limitations:
Support exists only for Extreme Networks certified SFP+ modules.
It can take 500-1000 ms to stabilize the channel after DWDM channel configuration is completed, meaning that the port loses its data transmission capability for that time frame. Links are dropped until the channel is stabilized. However, this is expected behavior when the physical medium is changed.
When a tunable dense wavelength division multiplexing (TDWDM) SFP+ module is inserted, the software configures the default channel or the configured channel based on the existing configuration, and the link is likely to be dropped during this process.
