N5548 and GLC-T Not Supported

[rtjensen4]

Hi All,

Just got a new 5548 Switch, and to my surprise, the GLC-T I ordered with it do not seem to be working...

According to this link, it should work:

Here's my show version:

From the output above,it seems to see the SFP, but it won't let me use it.

Any thoughts? I've tried to look around for any solutions, but none are popping out at me. Thanks in advance!

You are working with a bug my friend

http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsv02866

Or 'find' for CSCsv02866 here:

Please rate if helpful.

Bug ID CSCsv02866 is not the problem. This bug only filed against the message "Transceiver calibration is invalid" in the show interface x/x transceiver detail command which is cosmetic.

The problem in the interface is not configured correctly. As per the output of the show interface status command:

Eth1/15       --                 sfpInvali trunk     full    10G     1/10g

Eth1/15 is set to 10G (default) instead of the speed of the SFP which is 1GE. To correct this issue, use the command speed 1000 and duplex full under interface configuration mode.

int e1/15

speed 1000

duplex full

Verify it with show interface status and show interface e1/15 transceiver detail.

HTH,

jerry

I got it worked out, thanks! Turns out I have to set speed BEFORE inserting the SFP. The 'speed' command isn't available when it is in. I just had to remove the SFP, set speed 1000, then re-insert SFP. Seems odd / hokey to me, but hey, it works.

HI,

An other solution is to conf the interfaces in range mode and set speed to 1000 without unplugging the SFP's

command speed has been accepted

Model N5548P

  kickstart: version 5.0(2)N2(1)

  system:    version 5.0(2)N2(1)

it seems to be a workaround within a bug
