Issue pertaining to network configuration on RHEL


I am experiencing a issue in starting up Open view monitoring on couple of linux servers and here is the output from mii-tool looks like.

eth0: 100 Mbit, full duplex, link ok
eth1: 100 Mbit, full duplex, link ok
eth2: no link
eth3: no autonegotiation, 100baseTx-HD, link ok
eth4: no link

And, the NIC cards cabling is as follows.
NIC1 onboard – goes to monitoring
NIC2 onboard – goes to network switch1
External NIC port – goes to network switch2
Second external NIC port is not cabled

Based on what I understand, eth0 goes to monitoring and the other 2 ethernet cards go to FE.

I am not an expert in system administration but would like to know if there is any issues with the above settings/configuration (in fact, im also looking for what do they infer and what is the ideal settings? Any light on what changes (if any) need to be made would be greatly appreciated.

I see three links that are "ok". Two of them are connected to two different switches. The third one is connected to a monitor port.

What is the issue?

The issue is with bringing up Open View monitoring on those servers. I checked with my colleague and he suggested there may be network configuration issues on the box. Since I don't have complete understanding about what is causing the issue and my colleague is tied up with other issues so here I am trying to figure out what is the config change with respect to network that needs to be done(if any).

Do you see any issue with the way NIC cards are cabled and eth* setup? I can send you the any other config information if you want to know further details. Please advise.



configuration, eth, miitool, network, nic
