Hello,
I'm playing with ifwatchd on my laptop and have issue when connecting
the LAN cable back. The idea is use wireless when LAN is not connected
and back to LAN precedence when it is plugged.
I first though ifwatchd could cause this behaviour so I stopped
everything (ifwatchd, dhclient, wpa_supplicant, ntpd, ...).
With the cable plugged-in, I get:
wm0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
capabilities=7ff80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx,TCP6CSUM_Rx,TCP6CSUM_Tx,UDP6CSUM_Rx,UDP6CSUM_Tx,TSO6>
enabled=0
address: 00:15:58:86:c1:78
media: Ethernet autoselect (100baseTX
full-duplex,flowcontrol,rxpause,txpause)
status: active
inet 10.15.5.24 netmask 0xffffff00 broadcast 10.15.5.255
inet6 fe80::215:58ff:fe86:c178%wm0 prefixlen 64 scopeid 0x1
When I unplug the cable, I get:
wm0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
capabilities=7ff80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx,TCP6CSUM_Rx,TCP6CSUM_Tx,UDP6CSUM_Rx,UDP6CSUM_Tx,TSO6>
enabled=0
address: 00:15:58:86:c1:78
media: Ethernet autoselect (none)
status: no carrier
inet 10.15.5.24 netmask 0xffffff00 broadcast 10.15.5.255
inet6 fe80::215:58ff:fe86:c178%wm0 prefixlen 64 scopeid 0x1
When I plug the cable back, nothing happens - the NIC is still in "status:
no carrier". The only way to get my carrier back is to issue an
"ifconfig down ; ifconfig up".
I'm running 4.99.55/i386 on a Lenovo R61 and the NIC is:
wm0 at pci0 dev 25 function 0: Intel i82801H (M) LAN Controller, rev. 3
wm0: interrupting at ioapic0 pin 20 (irq 11)
wm0: PCI-Express bus
wm0: FLASH
wm0: Ethernet address 00:15:58:86:c1:78
igphy0 at wm0 phy 1: i82566 10/100/1000 media interface, rev. 0
Is this an expected behaviour ?
TIA,
Jo
