My question stems from 6509 blades that have some problem ports.
The ports will show up/up but will not pass traffic. I have found up to 6 ports per blade that are doing this. The attached device shows a connection, but canot get an IP address and the device mac-address does not populate the port table.
Reseating the blade seems to correct the problem, allowing me to use the ports.
But my question is, at what point does the mac-address of the attached workstation or device show up on the switch port that links that device to the network (found by using "sh mac-address int fx/x)?
What causes a successful entry of the device mac-address to the port?
