Hello!I might have encountered an issue with the Cisco C9300LM-24U switch. When using an GLC-TE SFP on one of the 25G SFP ports, I get a link but no layer 2 connections seems to work. when configuring switch 1 (9300LM) with ip 10.1.1.1/24 and switch ...
Yes, issue still remains, connection does not work!When I have the GLC-T in the IE2000 and connect the cable to a normal copper port on the C9300LM, the connection works!Vice versa, the connection also does not work!
I've tried a few things now:Version 17.09.03 - link comes up, but no arp entriesVersion 17.09.04 - no link comes up but sfp is recognizedVersion 17.12.01 - no link comes up but sfp is recognizedAny ideas?
