How to find the physical MAC of bonded NICs
Hello everyone,
I am trying to figure out how to determine the physical MAC Address of each of our NICs on 29 different servers. Each server has at least 2 NICS that are bonded and as I have learned each takes on a specific MAC from one of the NICs. My question, is how do I find the physical MAC of each NIC. I'm running RHEL 3.0 AS on these servers. Thanks in advance for any help. Sincerely, lhiggie |
cat /proc/net/bonding/bondX
where bondX is the name of your bonded interface, as: # cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v2.6.1 (October 29, 2004) Bonding Mode: fault-tolerance (active-backup) Primary Slave: eth2 Currently Active Slave: eth2 MII Status: up MII Polling Interval (ms): 1000 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth2 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:09:6b:9b:38:ae Slave Interface: eth3 MII Status: up Link Failure Count: 1 Permanent HW addr: 00:09:6b:9b:38:af |
hi,
run #ifconfig in "eth0" "eth1" etc you can see the MAC of that particular NIC. regards |
If they're bonded, all interfaces in the team including the bondX interface should show the same mac address. There may be bonding modes that allow the interfaces to have different mac address after the bonding, but it usually means that your ifenslave is outdated.

Solved!!!!
Thank you to all that responded!
