How to solve Cisco module compatibility issues?

Date:2018-10-24 12:24 From:C-LIGHT Onclick:
Cisco devices can only use Cisco-compatible optical transceiver by default. Optical modules from other manufacturers (not certified by Cisco) cannot be used. If other optical transceiver module is used on a Cisco device, the device Information such as Unknown or Unsupport will be displayed.



Cisco uses SFP encryption mechanism to verify the use of other brands SFP. Therefore, compatible optical transceiver have very high compatibility requirements. How to solve Cisco module compatibility problems? 

Solution:

1. Enter the configuration mode of the corresponding port .

2. Enter the following hidden command (cannot be pressed).

  Cisco(config)#service unsupported-transceiver
  Cisco(config)#no errdisable detect cause gbic-invalid
  Cisco(config)#speed nonegotiate

3.Save configuration.

After the above steps are completed, the Cisco device will not verify the optical transceiver that can be used normally.
 

Attached: special instructions for Cisco equipment:
(config)#service unsupported-transceiver
Warning: When Cisco determines that a fault or defect can be traced to the use of third-party transceivers installed by a customer or reseller, then, at Cisco's discretion, Cisco may withhold support under warranty or a Cisco support program. In the course of providing support for a Cisco networking product Cisco may require that the end user install Cisco transceivers if Cisco determines that removing third-party parts will assist Cisco in diagnosing the cause of a support issue.

Cisco has already accounted for nearly half of the global network equipment market, ahead of other competitors in the telecommunications industry. Success is largely due to the expansion of the switch market share. Many customers hesitate to buy Cisco SFP that is very expensive. In order to provide a cost-effective solution, Cisco compatible SFP modules came into being.
