Link status turning up and down continously

UNIX Solaris
1

Hi All,

Happy New Year.

I have a weird situation in one of my servers.The OS is solaris 10

We don't have bcme1 interface configured/plumbed on that system but every 5 second i get this message in /var/adm/messages

Jan  4 20:22:45 XXXX bcme: [ID 289540 kern.notice] NOTICE: bcme1 : Link is Up (1000Mbps, Full Duplex)
Jan  4 20:22:45 XXXX bcme: [ID 289540 kern.notice] NOTICE: bcme1 : No Link
Jan  4 20:58:00 XXXX bcme: [ID 289540 kern.notice] NOTICE: bcme1 : Link is Up (1000Mbps, Full Duplex)
Jan  4 20:58:01 XXXX bcme: [ID 289540 kern.notice] NOTICE: bcme1 : No Link

The o/p of ifconfig -a

# ifconfig -a

        inet 127.0.0.1 netmask ff000000

Since that interface is not enabled at all so i couldn't unplumb or bring down the interface.

Is there a way i can get rid of these messages and or uninstall the device driver for that interface so it wont be logging again.

Please help.

Thanks in advance.

the bcme0 interface is configured and has a "unknown" link status. check your switch for autoneg. this should be enabled.
