I've connected an INTIP card from an alcatel PABX to a switch (3548XL) and I have lot of runts input error in the interface :
sh int fa0/47
FastEthernet0/47 is up, line protocol is up
Hardware is Fast Ethernet, address is 0007.50c2.862f (bia 0007.50c2.862f)

What does it mean ? How to solve that ? I try to force the duplex and the speed in the intip card and in the interface of the switch with no success... The VLAN 1 is native and the VLAN 100 is in access on the interface.
At any point of time the reliability should be 255/255. If this falls down then you will notice the errors on the interface.
Its not that switch needs to have 255. But its how the interface is deisgned to notify if there is any problem with the harware inetrface or cable by dropping the reliability down from 255. If there is any other interface working clean with low reliability would be supriseing.
try to change the wire (cable) or the NIC, because the quality of the link is also not the best "reliability 222/255", i think it is a cable problem.
