My expedition into AMD64: Section 1
Posted by sneex on Tue 26 Jun 2007 at 14:09
Of the three 'identical' AMD64 servers, two say interface eth2 is 100MBits:
e100: eth2: e100_watchdog: link up, 100Mbps, full-duplex
eth0: Tigon3 [partno(BCM95704A7) rev 2100 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet 00:e0:81:47:f9:24
eth1: Tigon3 [partno(BCM95704A7) rev 2100 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet 00:e0:81:47:f9:25
One states that eth0 is 100MBits:
e100: eth0: e100_watchdog: link up, 100Mbps, full-duplex
eth0: Tigon3 [partno(BCM95704A7) rev 2100 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet 00:e0:81:48:31:f0
eth1: Tigon3 [partno(BCM95704A7) rev 2100 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet 00:e0:81:48:31:f1
Question is 'Why?' Why would Debian 4, using the DVD iso installation method, detect the same hardware differently?
So, after further research I see (for srv0) -
dmesg |grep e100
PCI: Firmware left 0000:03:08.0 e100 interrupts enabled, disabling
e100: Intel(R) PRO/100 Network Driver, 3.5.10-k2-NAPI
e100: Copyright(c) 1999-2005 Intel Corporation
e100: eth0: e100_probe: addr 0xfeafb000, irq 201, MAC addr 00:E0:81:48:31:E4
e100: eth0: e100_watchdog: link up, 100Mbps, full-duplex
However for srv1, I see -
dmesg |grep e100
PCI: Firmware left 0000:03:08.0 e100 interrupts enabled, disabling
e100: Intel(R) PRO/100 Network Driver, 3.5.10-k2-NAPI
e100: Copyright(c) 1999-2005 Intel Corporation
e100: eth0: e100_probe: addr 0xfeafb000, irq 177, MAC addr 00:E0:81:47:F9:96
e100: eth2: e100_watchdog: link up, 100Mbps, full-duplex
(NOTE: The 3rd server was hosed while researching why these first two systems do not agree as to the hardware interface; so it's not reported on this AMD64 Section.)
What I am getting at is this: The hardware is the same but the installer doesn't see the same interfaces. In the long run I guess it doesn't matter. I simply want the 1GBit interfaces to plumb-up to my internal/private routes and the 100MBit interfaces to plumb-up to the public/Internet routes. As I have never seen this behavior before it struck me as a little weird.

Looks like the same system, I see the IRQs are different, but would that be enough to cause the 100MHz Ethernet interface show up differently?

By now you have probably found /etc/ifup ? :)

*cough* /etc/iftab, was it
