Command Usage
◆
If an SFP transceiver is inserted in a port, the Type field will show the SFP type
as interpreted from Ethernet Compliance Codes (Data Byte 6 in Address A0h).
The Ethernet Compliance Code is a bitmap value, of which one bit is
supposedly turned on. However, if the read-out is not recognizable (e.g., 2 or
more bits on, or all 0s), the Type field just displays the raw data (hexadecimal
value).
◆
The Type field will always display “NA” for a trunk entry because a trunk allows
for mixed port types such as 1000Base T and 1000Base SFP.
