[c-nsp] PHY-4-MODULE_DUP Message

Hello group,

Another one that I see for the first time:

1) ME3750 running 12.2.52.SE without issues

2) for some reason, a connection to a 6500 goes down:

%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/2,
changed state to down
%LINK-3-UPDOWN: Interface GigabitEthernet1/0/2, changed state to down

3) in the troubleshooting process, the GLC-T was moved from Gi1/0/2 to
Gi1/0/1 and surprise:

%PHY-4-MODULE_DUP: SFPs in Gi1/0/1 and in Gi1/0/2 have duplicate vendor-id
and serial numbers
%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi1/0/1, putting Gi1/0/1
in err-disable state

4) reloading the ME3750 solves the problem

Anyone has seen something like this ? The GLC-T is Cisco. The idprom command
says the following:

General SFP Information
Identifier            :   0x03
Connector             :   0x00
Transceiver           :   0x00 0x00 0x00 0x08 0x00 0x00 0x00 0x00
Encoding              :   0x01
BR_Nominal            :   0x0D
Vendor Name           :   CISCO-METHODE   
Vendor Part Number    :   SP7041          
Vendor Revision       :   0x45 0x20 0x20 0x20
Vendor Serial Number  :   00000MTC130601MK

It seems to be an IOS issue that may be triggered by a GLC-T problem. Any
hints ?
