Information about NIC teaming support for Cisco CallManager 5.1 on IBM Media Convergence Servers (MCS) servers:
Cisco CallManager 5.x on Linux does not support NIC teaming on IBM MCS. Call Processing provides this information about NIC teaming for network tolerance:
Hewlett-Packard (HP) server platforms with dual Ethernet NICs can support NIC teaming for network fault tolerance with Cisco Unified CallManager 5.0. This feature allows a server to be connected to the Ethernet through two NICs and, hence, two cables. NIC teaming prevents network downtime because it transfers the workload from the failed port to the functional port. NIC teaming cannot be used for load balancing or to increase the interface speed.
