You need to access status information about your bonded NIC interfaces.

决议

The current state of a bonded interface can be found in /proc/net/bonding/bond<N>. For example, for bond0:

Raw

# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: 2.6.1 (October 29, 2004)
Bonding Mode: load balancing (round-robin)
Currently Active Slave: eth0
MII Status: up
MII Polling Interval (ms): 1000
Up Delay (ms): 0
Down Delay (ms): 0

Slave Interface: eth1
MII Status: up
Link Failure Count: 1

Slave Interface: eth0
MII Status: up
Link Failure Count: 1

Bonding Mode: shows the current mode. For more information on available bonding modes, refer to: What are the different modes available for bonded interfaces (bonding) in Red Hat Enterprise Linux version 3? http://kbase.redhat.com/faq/docs/DOC-8108
Currently Active Slave: shows which interface is currently being used. This is usually useful only in active-backup mode, since load-balancing modes will alternate.
MII Status: shows whether each interface is currently up or down. In the first section, it shows whether the bond itself is currently up.
Link Failure Count: shows the number of times a link has failed while in use. This can be help to identify a failing NIC.
