Displaying the Physical Attributes of Datalinks

Use the dladm show-phys command to obtain information about the system's datalinks in relation to the physical NICs with which they are associated. Used without any options, the command displays information that is similar to the following example:

# dladm show-phys
LINK        MEDIA          STATE     SPEED     DUPLEX     DEVICE
net0        Ethernet       up        100Mb     full       e1000g0
net1        Ethernet       down      0Mb       --         nge0
net2        Ethernet       up        100Mb     full       bge0
net3        InfiniBand     --        0Mb       --         ibd0

The previous output shows, among other details, the physical NICs with which the datalinks that have generic link names are associated. For example, net0 is the datalink name of the NIC e1000g0. To display information about flags that have been set for the datalinks, use the –P option. For example, a datalink that is flagged with r means that its underlying NIC has been removed.

In the previous output, the STATE column shows the current state of the physical datalink. The state can be up, down, or unknown. The physical link state identifies whether the physical device has connectivity with the external network (which it does, if the cable is plugged in and the state of the port on the other end of the cable is up.

The –L option is another useful option that you can use. This option displays the physical location for each datalink. The location determines the instance number of the datalink, such as net0, net1, and so on.

# dladm show-phys -L
net0     bge0       MB
net2     ibp0       MB/RISER0/PCIE0/PORT1
net3     ibp1       MB/RISER0/PCIE0/PORT2
net4     eoib2      MB/RISER0/PCIE0/PORT1/cloud-nm2gw-2/1A-ETH-2

Use the –m option to display the MAC addresses of the physical links in a system:

# dladm show-phys -m
LINK                SLOT     ADDRESS            INUSE CLIENT
net0                primary  0:11:22:a9:ee:66   yes   net0

This command is similar to using the ifconfig command.

Display the MAC addresses of all of the links in a system (physical and non-physical) as follows:

# dladm show-linkprop -p mac-address
net0     mac-address     rw   0:11:22:a9:ee:66 0:11:22:a9:ee:66 0:11:22:a9:ee:66
