When I do this: [mini] /usr/home/ianf # ifconfig alc0 media 100BaseTX mediaopt full-duplex I get this on the switch: 08-Oct-2009 12:26:42 %STP-W-PORTSTATUS: g14 of instance 0: STP status Forwarding 08-Oct-2009 12:26:42 %STP-W-PORTSTATUS: g14 of instance 1: STP status Forwarding 08-Oct-2009 12:26:42 %STP-W-PORTSTATUS: g14 of instance 2: STP status Forwarding 08-Oct-2009 12:26:42 %LINK-I-Up: g14 wgsw-24010# sh interfaces status ethernet g14 Flow Link Back Mdix Port Type Duplex Speed Neg ctrl State Pressure Mode -------- ------------ ------ ----- -------- ---- ----------- -------- ------- g14 1G-Copper Full 100 Enabled Off Up Disabled Off So, it correctly detects full duplex. The cable tester still reports the cable os open at 2m, probably because it expects all 4 pairs to be terminated. > I couldn't see link establishment issues on AR8132 sample board. > Does link partner also see no link when you use auto-negotiation on > alc(4)? I get no link, not even temporary blips on the link light. When I invoke the cable tester, this is what I see: wgsw-24010# test copper-port tdr g14 .. Cable on port g14 is open at 2 m > Does your link partner support 1000baseT link? Yes, it does. > Can you see blinking LED of AR8132 when link was not established?

No difference either. > How about checking MIB statistics of controller? > (sysctl dev.alc.0.stats) This is after a reboot, but the link was up for a short while to do the above testing. rx.good_frames looks a bit high for "up 21 mins". dev.alc.0.stats.rx.good_frames: 3348588249 dev.alc.0.stats.rx.good_bcast_frames: 0 dev.alc.0.stats.rx.good_mcast_frames: 0 dev.alc.0.stats.rx.pause_frames: 0 dev.alc.0.stats.rx.control_frames: 0 dev.alc.0.stats.rx.crc_errs: 0 dev.alc.0.stats.rx.len_errs: 0 dev.alc.0.stats.rx.good_octets: 0 dev.alc.0.stats.rx.good_bcast_octets: 0 dev.alc.0.stats.rx.good_mcast_octets: 0 dev.alc.0.stats.rx.runts: 0 dev.alc.0.stats.rx.fragments: 0 dev.alc.0.stats.rx.frames_64: 13 dev.alc.0.stats.rx.frames_65_127: 5 dev.alc.0.stats.rx.frames_128_255: 181 dev.alc.0.stats.rx.frames_256_511: 2 dev.alc.0.stats.rx.frames_512_1023: 0 dev.alc.0.stats.rx.frames_1024_1518: 0 dev.alc.0.stats.rx.frames_1519_max: 0 dev.alc.0.stats.rx.trunc_errs: 0 dev.alc.0.stats.rx.fifo_oflows: 0 dev.alc.0.stats.rx.rrs_errs: 0 dev.alc.0.stats.rx.align_errs: 0 dev.alc.0.stats.rx.filtered: 201 dev.alc.0.stats.tx.good_frames: 0 dev.alc.0.stats.tx.good_bcast_frames: 0 dev.alc.0.stats.tx.good_mcast_frames: 0 dev.alc.0.stats.tx.pause_frames: 0 dev.alc.0.stats.tx.control_frames: 0 dev.alc.0.stats.tx.excess_defers: 0 dev.alc.0.stats.tx.defers: 0 dev.alc.0.stats.tx.good_octets: 0 dev.alc.0.stats.tx.good_bcast_octets: 0 dev.alc.0.stats.tx.good_mcast_octets: 0 dev.alc.0.stats.tx.frames_64: 0 dev.alc.0.stats.tx.frames_65_127: 0 dev.alc.0.stats.tx.frames_128_255: 0 dev.alc.0.stats.tx.frames_256_511: 0 dev.alc.0.stats.tx.frames_512_1023: 0 dev.alc.0.stats.tx.frames_1024_1518: 0 dev.alc.0.stats.tx.frames_1519_max: 0 dev.alc.0.stats.tx.single_colls: 0 dev.alc.0.stats.tx.multi_colls: 0 dev.alc.0.stats.tx.late_colls: 0 dev.alc.0.stats.tx.excess_colls: 0 dev.alc.0.stats.tx.abort: 0 dev.alc.0.stats.tx.underruns: 0 dev.alc.0.stats.tx.desc_underruns: 0 dev.alc.0.stats.tx.len_errs: 0 dev.alc.0.stats.tx.trunc_errs: 0 dev.alc.0.stats.rx.filtered is not climbing with outo-negotiate enabled.
