Monitoring Link Aggregation Status | Apple 10.6 specification

The interface name bond<num> assigned by the system is different from the name you give to the link aggregate port configuration. The interface name is for use at the command line, but the port configuration name is for use in the Network pane of System Preferences.

For example, if you enter the command ifconfig -a,the output refers to the link aggregate using the interface name and not the port configuration name:

bond0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::2e0:edff:fe08:3ea6 prefixlen 64 scopeid 0xc

inet 10.0.0.12 netmask 0xffffff00 broadcast 10.0.0.255 ether 00:e0:ed:08:3e:a6

media: autoselect (100baseTX <full-duplex>) status: active

supported media: autoselect

bond interfaces: en1 en2 en3 en4

You do not delete or remove a link bond from the Network Pane of System Preferences. You remove the bond through the Manage Virtual Interfaces sheet used to create the bond.

Monitoring Link Aggregation Status

You can monitor the status of a link aggregate in Mac OS X and Mac OS X Server using the Status pane of the Network pane of System Preferences.

To monitor the status of a link aggregate:

1Open System Preferences.

2Click Network.

3From the list of network interfaces on the left, choose the link aggregate port virtual interface.

4Click Advanced in the lower right side of the window.

5Select the Bond Status tab.

The Status pane displays a list containing a row for each physical link in the link aggregate. For each link, you can view the name of the network interface, its speed, its duplex setting, the status indicators for incoming and outgoing traffic, and an overall assessment of the status.

Note: The Sending and Receiving status indicators are color-coded. Green means the link is active (turned on) and connected. Yellow means the link is active but not connected. Red means the link can’t send or receive traffic.

6To view more information about a link, click the corresponding entry in the list.
