ETH2 showing instead of ETH1

JimboMar 20 2014 — edited Mar 20 2014


Hi,

I have just replaced a faulty NIC in my server

When I do ifconfig it shows

eth0      Link encap:Ethernet  HWaddr 00:19:BB:DE:9C:10
          inet addr:192.168.0.5  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::219:bbff:fede:9c10/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:4480 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6625 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:293552 (286.6 KiB)  TX bytes:7711608 (7.3 MiB)
          Interrupt:17

eth2      Link encap:Ethernet  HWaddr 00:E0:4A:08:F3:56
          inet6 addr: fe80::2e0:4aff:fe08:f356/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:3 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:258 (258.0 b)

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:214 errors:0 dropped:0 overruns:0 frame:0
          TX packets:214 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:17436 (17.0 KiB)  TX bytes:17436 (17.0 KiB)

It seems to have replaced ETH1 with ETH2. Yet it has not assigned the Static IP I have given the NIC

When on the Console I look at SYSTEM - PREFERENCES - NETWORK CONNECTIONS I see

System eth0 - this is set to the IP address above and the MAC address

System eth1 - this is set to the IP I want ( 192.168.2.97 ), has the Method set to Manual and also has Connect Automatically ticked

However I notice that the MAC address for ETH1 in the system console ( 00:E0:4A:08:9C:4D ) is different from that show by ifconfigfor ETH2 ( 00:e0:4A:08:F3:56 )

Q1. Why is ifconfig showing something completrly different i.e. ETH2 instead of ETH1 ?

Q2. Why is ifconfig only showing inet6 for eth2 and not inet ( i.e. IP v4 )

Q3. Is the Server console holding onto the old MAC address of the failed NIC ? Is there some sort of Discovery process I need to run ? Or do I need to manually change this MAC address on the server console for ETH1 to be the new MAC address i.e. that shown under ETH2 of ifconfig above ?

Any help appreciated

Jim
