[ale] Issue with eth0 appeared after setting up ethernet bonding

[Ryan Fish]

I'm hoping one or more of you out there can help with this strange issue I'm
seeing.

 

OS: RHEL 3 ES

 

NICs (onboard): 

01:03.0 Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet
Controller (Copper) (rev 01)

01:03.1 Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet
Controller (Copper) (rev 01)

 

Settings for eth0:

        Supported ports: [ TP ]

        Supported link modes:   10baseT/Half 10baseT/Full 

                                100baseT/Half 100baseT/Full 

                                1000baseT/Full 

        Supports auto-negotiation: Yes

        Advertised link modes:  10baseT/Half 10baseT/Full 

                                100baseT/Half 100baseT/Full

        Advertised auto-negotiation: Yes

        Speed: 100Mb/s

        Duplex: Half

        Port: Twisted Pair

        PHYAD: 0

        Transceiver: internal

        Auto-negotiation: on

        Supports Wake-on: umbg

        Wake-on: d

        Current message level: 0x00000007 (7)

        Link detected: yes

Settings for eth1:

        Supported ports: [ TP ]

        Supported link modes:   10baseT/Half 10baseT/Full 

                                100baseT/Half 100baseT/Full 

                                1000baseT/Full 

        Supports auto-negotiation: Yes

        Advertised link modes:  10baseT/Half 10baseT/Full 

                                100baseT/Half 100baseT/Full 

                                1000baseT/Full 

        Advertised auto-negotiation: Yes

        Speed: 1000Mb/s

        Duplex: Full

        Port: Twisted Pair

        PHYAD: 0

        Transceiver: internal

        Auto-negotiation: on

        Supports Wake-on: umbg

        Wake-on: d

        Current message level: 0x00000007 (7)

        Link detected: yes

 

The basic issue is that no matter how many times I've tried to manually
force eth0 to 1000/FD/Autoneg via "ethtool -s" it always stays at
100/HD/Auto.  ETH0 was being used by a second IP on this box prior to the
bonding being put in place so this just started happening afterwards.  It
was able to connect at 1000/FD without any issues or any sort prior.

 

All of the bonding settings:

 

/etc/modules.conf

alias eth0 e1000

alias eth1 e1000

alias usb-controller usb-ohci

alias bond0 bonding miimon=100 mode=0

 

 

ifcfg-bond0 

DEVICE=bond0

ONBOOT=yes

BOOTPROTO=none

IPADDR=10.18.62.110

NETMASK=255.255.255.0

BROADCAST=10.18.62.255

NETWORK=10.18.62.0

USERCTL=no

 

 

ifcfg-eth0

# Intel Corp.|82546EB Gigabit Ethernet Controller (Copper)

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=none

HWADDR=00:04:23:9A:A9:9A

MASTER=bond0

SLAVE=yes

USERCTL=no

 

 

ifcfg-eth1

# Intel Corp.|82546EB Gigabit Ethernet Controller (Copper)

DEVICE=eth1

BOOTPROTO=none

HWADDR=00:04:23:9A:A9:9B

ONBOOT=yes

MASTER=bond0

SLAVE=yes

USERCTL=no

 

 

Any thoughts on what the cause of this issue could be?  Bonding on the same
hardware with the same NICs is working just fine elsewhere within the
network.

 

Thank you.
