  Yes, this is exactly our operational procedure for links with transceivers
not supporting DOM. Fortunately, starting with CWDM GBICs DOM is supported
- so instead of de-configuring autonegotiation (which requires enable level)
our NOC operators can simply issue "show inte transceiver" and get much better
info. Because of this, we only buy DOM-capable transceivers on all purchases.


	With kind regards,
