Hi, I've recently installed a GLC-LH-SMD in my existing 2921 router running 15.2(4)M3 version of IOS. According to the Digital Optical Monitoring Compatibility Matrix, that SFP is capable of DOM, but when I sh int <int id> transceiver, it returns Module 0 doesn't support DOM. Any ideas whether this is an SFP issue, a router issue or a code version issue?
Thanks for any help,
Sam
