Hey all,

I have two nic's in my work PC running 10.04 32-bit desktop. Eth0 and eth1 are both connected to the same LAN using static IPs. Now, this works fine until I use eth1 for its intended purpose which is using it to monitor the network. The port on the switch it is connected to is setup as a Cisco SPAN port. Everytime the SPAN session is setup, I lose connectivity to the LAN as it appears to be prioritizing traffic to eth1. I tried the only command I could find about setting the metric of the iface which is--

sudo ifconfig eth1 inet metric 10

When I run that, I get an error stating SIOCSIFMETRIC: Operation not supported.

Anyone know what I am missing???
