There's nothing wrong with the switch, since a dozen other FreeBSD machines (using bge or fxp) all work fine on it. I've looked through many similar problem reports online and none of the diagnostic steps or fixes have helped. No errors of any kind are reported.. the networking simply does not work, as if the interface were down. Changing to the other switch, it works perfectly. I unfortunately do not have the details about what models the two different switches are, as they're in a remote datacenter and my remote assistant gave up in frustration after the millionth time I had him juggle connections around. dmesg: em0: port 0xcc00-0xcc3f mem 0xfc9e0000-0xfc9fffff irq 74 at device 1.0 on pci5 em0: [FILTER] em0: Ethernet address: 00:30:48:85:b0:44 sysctl -a: dev.em.0.%desc: Intel(R) PRO/1000 Network Connection 6.9.21 dev.em.0.%driver: em dev.em.0.%location: slot=1 function=0 dev.em.0.%pnpinfo: vendor=0x8086 device=0x1076 subvendor=0x15d9 subdevice=0x1076 class=0x020000 dev.em.0.%parent: pci5 dev.em.0.debug: -1 dev.em.0.stats: -1 dev.em.0.rx_int_delay: 0 dev.em.0.tx_int_delay: 66 dev.em.0.rx_abs_int_delay: 66 dev.em.0.tx_abs_int_delay: 66 dev.em.0.rx_processing_limit: 100 ifconfig -a: em0: flags=8843 metric 0 mtu 1500 options=389b ether 00:30:48:85:b0:44 inet 10.0.0.104 netmask 0xffffff00 broadcast 10.0.0.255 media: Ethernet autoselect (1000baseT ) status: active netstat -rn: Destination Gateway Flags Refs Use Netif Expire 10.0.0.0/24 link#1 U 0 8 em0 >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
