Two listings of the mii-diag tool follow, see http://www.scyld.com/diag/. # 3Com Corporation 3c900B-TPC [Etherlink XL TPC], 10 Mbps network $ ./mii-diag eth0 Basic registers of MII PHY #24: 0100 180d 0000 0000 0061 0020 0000 0000. Basic mode control register 0x0100: Auto-negotiation disabled, with Speed fixed at 10 mbps, full-duplex. You have link beat, and everything is working OK. Your link partner is generating 10baseT link beat (no autonegotiation). # Intel Corporation 82557 [Ethernet Pro 100], 100 Mbps network $ ./mii-diag eth1 Basic registers of MII PHY #1: 3000 782d 02a8 0154 05e1 45e1 0001 0000. Basic mode control register 0x3000: Auto-negotiation enabled. You have link beat, and everything is working OK. Your link partner advertised 45e1: Flow-control 100baseTx-FD 100baseTx 10baseT-FD 10baseT, w/ 802.3X flow control. -- Alexandr.Malusek@imv.liu.se
