baseline

I just installed a 3com 2952-sfp, and I had its port #48 connected to another gigabit switch through a cat5e cable.

Now when I look at the logs, I see the lines shown below:

Mar 23 11:20:15:829 2010 MSTP Critical PFWD Instance 0's GigabitEthernet1/0/48 has been set to forwarding state! 
Mar 23 11:20:15:822 2010 IFNET Warning LINK UPDOWN GigabitEthernet1/0/48: link status is UP  
Mar 23 11:20:12:974 2010 IFNET Warning LINK UPDOWN GigabitEthernet1/0/48: link status is DOWN

The above happens like dozens of times per day, is there something wrong with my setup?
