Cisco MPX NIC and services problem
To successfully activate NIC card with wrong MAC address under MPX deployment please follow: - first change MAC address to right one under RedHat with root access vim /etc/sysconfig/network-scripts/ifcfg-eth0 (or whatever is your NIC card...) change HWADDR field - restart MPX services in /opt/cisco/meetingplace_express/bin... sudo mpx_sys restart That's it! It should stop and start MPX services in the right order which is very important...
