problem with network interface
 

Hi guys,

I have a ce (quad giga swift card) and an eri interface. I set them up using the ifconfig command (plumb and up). I get the correct info when I do ifconfig -a. Say I activate the eri0, ce0, and ce3 ports.

My problem is: I can connect rempotely to the Server only via one port!!!!!

For example when all three interfaces are up I can only connect with one...if I unplumb 2 and leave only one..then I can connect through this one...why is this happenind?!? any idea?

Would you mind sharing it ?
What happen with the others ?
Have you snooped the network traffic ?

Hi,
tnx for answering..

1) ifconfig -a:


# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
ce0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 129.192.128.150 netmask ffffffc0 broadcast 129.192.128.191
ether 0:3:ba:b2:f0:78
ce3: flags=1000803<UP,BROADCAST,MULTICAST,IPv4> mtu 1500 index 3
inet 129.192.128.152 netmask ffffffc0 broadcast 129.192.128.191
ether 0:3:ba:b2:f0:7b
eri0: flags=1000803<UP,BROADCAST,MULTICAST,IPv4> mtu 1500 index 4
inet 129.192.128.153 netmask ffffffc0 broadcast 129.192.128.191
ether 0:3:ba:cd:8:a1


2) I cannot telnet using the other 2 ports...I mean.if ce0 is there I can onlyuse ce0...if I remove ce0 then I can nly use ce3..if I remove ce3 also and keep only eri0 I can connect using eri0..

hope this helps.

What do you mean by "I cannot telnet using the other 2 ports." ?

HI,

I have been told that it is not possible to have two different ethernet interfaces on the same segment..is that true??

Example:

ce0 => 129.192.129.155
eri0=> 129.192.129.150

this is not possible..and it seems they are right...do u agree?

I definitely do not agree.
It is obviously possible to have many interfaces on the same network, and even recommended when high availability is needed.

Can you also show the netstat -rn?

And make sure that your network routing information is correct?

Also can you ping the interfaces?

There is absolutely no reason why you cant have 2 or more interfaces on the same network segment.

As you can see, this interface is missing the flag "RUNNING".
This means that not all required resources are available.
What does `dmesg`say?
I assume it is a driver problem.
What does `modinfo | grep CE`say?
