    ETH2 showing instead of ETH1

    Jimbo


      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

      eth2      Link encap:Ethernet  HWaddr 00:E0:4A:08:F3:56
                inet6 addr: fe80::2e0:4aff:fe08:f356/64 Scope:Link

      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
