Bonding slave interfaces link using bnx2x module keeps flapping in RHEL 5
Issue
- Slave interface link is flapping continously:
kernel: bnx2x: eth0 NIC Link is Down
kernel: bonding: bond0: link status definitely down for interface eth0, disabling it
kernel: bonding: bond0: making interface eth1 the new active one.
kernel: bnx2x: eth0 NIC Link is Down
kernel: bnx2x: eth0 NIC Link is Up, 10000 Mbps full duplex, receive & transmit flow control ON
kernel: bonding: bond0: link status up for interface eth0, enabling it in 30000 ms.
kernel: bnx2x: eth0 NIC Link is Up, 10000 Mbps full duplex, receive & transmit flow control ON
kernel: bnx2x: eth0 NIC Link is Down
kernel: bonding: bond0: link status down again after 25200 ms for interface eth0.
