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.
Restrictions
•
Supports only 100BASE SFPs and 1000BASE SFPs under two speed configurations:
•
100 Mbps speed for 100BASE SFPs
