I do this wherever I can but some boxes either can't be nailed down or I haven't discovered how yet. In general I've had good results by always locking the settings at the switch and letting the computers I can't control autosense. I mistook fxp0 for another case of 'defaults to autosense'. >>>I use lots of fxp cards on a couple of Cat 1900s in 10BaseT Full duplex >>>mode without any errors.

Your formatting is completely different from mine so I thought your counters were from the fxp0 end. Was that from a 1900 switch? I don't have any of those. My 24xx switches (except for the 2948G, which is completely different) show counters like this: zzzzz#show int f0/5 FastEthernet0/5 is up, line protocol is up Hardware is Fast Ethernet, address is 0090.abee.1f05 (bia 0090.abee.1f05) Description: 557a-schilke MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255 Encapsulation ARPA, loopback not set, keepalive not set Full-duplex, 100Mb/s, 100BaseTX/FX ARP type: ARPA, ARP Timeout 04:00:00 Last input never, output 00:00:01, output hang never Last clearing of "show interface" counters 00:06:02 Queueing strategy: fifo Output queue 0/40, 0 drops; input queue 0/75, 0 drops 5 minute input rate 131000 bits/sec, 2 packets/sec 5 minute output rate 4000 bits/sec, 4 packets/sec 9626 packets input, 11282119 bytes, 0 no buffer Received 2 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 0 watchdog, 0 multicast 0 input packets with dribble condition detected 4981 packets output, 693845 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier 0 output buffer failures, 0 output buffers swapped out Yours are a lot easier to read! -Mitch To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
