cat 4500 oob mgmt port fa1 1000Mb/s, how come?

Hi guys,

i'm trying to figure out one thing today - wheter it is some kind of bug or feature.

Somebody from our monitoring team approached me to check a port fa1 on our cat4500 switch. Cause they're getting some port utilization abnormalities.

I checked the port - and it is an out of band management port, it's labeled as fastethernet but it really shows 1000Mb/s speed.

How is this possible? :)

FastEthernet1 is up, line protocol is up Hardware is Fast Ethernet for out of band management, address is Description: Internet address is MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 1000Mb/s, 100BaseTX/FX

BTW there are no errors seen on the port itself :)

Thanks for help ;)
