Was trying to upgrade a remote NIC in-flight from a (fixed) 10BASE-T FD to (fixed) 100BASE-T FD; on a Cisco switch with fixed rates:
# ifconfig xl0 media 100baseTX mediaopt full-duplex This is what I issued, then nothing more came up on my remote terminal (ssh). Last resort: Had to drive a few kms to remote server room. My 3.7 was simply frozen. No local keyboard access; no other term, no answer from NIC; no dump. 'Frozen' at its best. Anything I made wrong ? - Since it is a machine fully administrated remotely, there was no good chance to 'up-down'. Plus, it is in production, so 'up-down' or reboot are not desirable. Of course, no chance here to try to reproduce the matter. But a hint how to avoid it next time would be welcome, Uwe
