Good evening list,
Cisco has claimed that the following optics are compatible:
SFP-GE-S=
1000BASE-SX SFP transceiver module for MMF, 850-nm wavelength, extended
operating temperature range and DOM support, dual LC/PC connector
GLC-SX-MM=
1000BASE-SX SFP transceiver module for MMF, 850-nm wavelength, dual LC/PC
connector
I have a mindbender of a problem going on in both the lab and production
currently. I have an ASR9006 running IOX 4.1.1 with:
NAME: "module 0/0/CPU0", DESCR: "2-Port 10GE, 20-Port GE Line Card, Requires
XFPs and SFPs"
PID: A9K-2T20GE-B , VID: V04, SN: FOC152786XX
And in port 19 a SFP-GE-S:
NAME: "module mau GigabitEthernet0/0/CPU0/19", DESCR: "1000BASE-SX SFP
(DOM), MMF, 550/220m"
PID: SFP-GE-S , VID: V01 , SN: FNS15411KXX
The interface on the asr is showing up/up.

If I shutdown gig6/1 on the 6500, gig0/0/0/19 goes down on the asr9k. These
are all genuine Cisco optics and we have a TAC case pending, but as this
behavior is repeatable I thought it would be a good idea to ask for the
experience of others.
There is the possibility that we are missing something obvious in the
config? We are not the most experienced group with the asr9k's or IOS-XR.

end
The configuration is absolutely vanilla.
Any help or thoughts would be greatly appreciated.
Thanks!
