Configuring SFPs

The SFP driver is responsible for periodically monitoring the SFP for any change in the SFP status or SFP type. Once an SFP module is detected, the SFP driver reads the contents of the SFP EEPROM cookie and validates the SFP. When a valid SFP is detected, the SFP speed and SFP duplex restrictions are applied on the PHY chip and reflected in Cisco CLI.

Configuring Third-Party SFPs

Small Form-Factor Pluggables (SFPs) that are not Cisco certified are called third-party SFPs. Cisco approved means the SFPs have undergone rigorous testing with Cisco products and the SFPs are guaranteed to have 100% compatibility.

Third-party SFPs are manufactured by companies that are not on the Cisco-approved Vendor List (AVL). Currently, Cisco ISR G2 routers support only Cisco-approved SFPs. From Release 15.3(2)T, Cisco ISR G2 routers recognize third-party SFPs.

Note Cisco does not provide any kind of support for the third-party SFPs because they are not validated by Cisco.
