Unlikely. We use Intel NIC's (both 1GbE and 10GbE) extensively (up to 16 linkes per machine) for link monitoring without issues.
Great to know thanks ..
Try connecting the two links to each other. Set their respective IP's to 1.1.1.1/255.255.255.0 (eth1) and 2.2.2.2/255.255.255.0 (eth2). Now, check that they both auto negotiate to 1GbE/Full duplex. If they don't, you have a wire issue. (Is it CAT 5 or above?) If they do, do the following:
- Install iptraf. ($ yum install iptraf -y)
- Launch iptrag and configure it to work in promiscuous mode (Configure
-> Force promiscuous mode). 3. Go back, select the "general interface statistics". 4. From another console, start flood pinging. ping -s 1400 -f -i eth2 -b 1.1.1.255 5. Return to the iptraf console, you should the see the packet increase linearly on both interfaces. If it doesn't, something is broken, if it does - you have a switch problem.
Great idea ... I will try this when I'm able ..
