How do I tell the port speed of my NIC in FreeBSD?


To view the port speed of your NIC, type:

# /sbin/ifconfig

Locate media in the output of the file. You can also alter the search parameters as so:

$ /sbin/ifconfig | grep media
$ /sbin/ifconfig {interface} | grep media
$ /sbin/ifconfig em0 | grep media
$ /sbin/ifconfig

Sample output:

em0: flags=8943 metric 0 mtu 1500
options=19b
ether 00:30:48:98:9c:bc
inet 10.24.116.2 netmask 0xffffffc0 broadcast 10.24.116.63
media: Ethernet 10baseT/UTP
status: active


As you can see, the media parameter of the file states 'Ethernet 10baseT/UTP'.
