Hello,
Requirement: connecting 2 lan switches with SFP cable.
The LAN Switches to be connected are: C3560-24TS+2SFP with C3750-24TS+2SFP
Cable SFP: CAB-SFP-50CM-cable
when the installation is done, the error show up in the SFP interface, as below:
Port Name Status Vlan Duplex Speed Type
Gi1/0/1 err-disabled 1 auto auto unknown
Test_Switch#sh interfaces status err-disabled
suspected err is from the cable, which is not working for both lan switch.
Port Name Status Reason
Gi1/0/1 err-disabled gbic-invalid
Question: what type of cabling is suitable/compatible to be used for connecting 2 different types of lan switches?
Run the errdisable recovery but not help much.
Thanks in advance.
Regards,
Hira

Hi
As I understand it, you can only use that cable with 3560s:
Quote 'The Catalyst 3560 switch supports the SFP module patch cable, a 1/2 meter, copper, passive cable with SFP module connectors at each end. The patch cable can connect two Catalyst 3560 switches in a cascaded configuration. '

Hello,
Yap, you are correct. that cable can be only used for 3560s.
I want to order below SFP for connecting the C3560 with C3750:
Cisco Gigabit Ethernet SFP: Cisco 1000BASE-T SFP
Part Number: GLC-T SFP-GET3
Description: 1000BASE-T SFP Transceiver Module for Category 5 copper wire.
is that a correct SFP type?
Thanks again

GBIC-invalid would probably means that you have a non-Cisco SFP.
