FreeBSD ifconfig display capability and supported media types for an interface
FreeBSD ifconfig display capability and supported media types for an interface
ifconfig FreeBSD utility is used to configure network interface parameters. To display the capability and supported media types of an interface the
-m argument must be used.
Ex:
Code:
# ifconfig -m em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=5b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,POLLING>
capabilities=5b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,POLLING>
inet 82.78.227.177 netmask 0xfffffff0 broadcast 82.78.227.191
ether 00:04:23:c7:94:50
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
supported media:
media autoselect
media 1000baseTX
media 1000baseTX mediaopt full-duplex
media 100baseTX mediaopt full-duplex
media 100baseTX
media 10baseT/UTP mediaopt full-duplex
media 10baseT/UTP
Quote:
The ifconfig utility displays the current configuration for a network
interface when no optional parameters are supplied. If a protocol family
is specified, ifconfig will report only the details specific to that pro-
tocol family.
If the -m flag is passed before an interface name, ifconfig will display
the capability list and all of the supported media for the specified
interface. If -L flag is supplied, address lifetime is displayed for
IPv6 addresses, as time offset string.
