A System for Detecting Network Configuration Errors within a Virtual Environment

Disclosed is a system for detecting network configuration errors within a virtual environment. The system checks consistency of a configuration of a Virtual Machine (VM) in the virtual environment such as, but not limited to, VMware*. The system utilizes an automated process to check for inconsistent configurations wherein the inconsistent configurations are not flagged by other tools. In addition, the system baselines an existing network connectivity of the VM. The system monitors network performance statistics of the VM prior to migration, during migration and after migration. The system also utilizes the configuration, statistics and ping results on an existing network and a proposed network infrastructure of a migrated VM for monitoring network performance statistics of the VM. Additionally, the system utilizes a combination of internal and external sources to determine the configuration and an availability of the VM network associated with the migrated VM. Further, the system utilizes Cisco Discovery Protocol (CDP**) values and Link Layer Discovery Protocol (LLDP) values of a physical device to detect possible points of failure.

The system utilizes a command line interface tool to assess four areas of network connectivity between a virtual server, a host and associated network switches. The four areas correspond to a communication, the CDP values and the LLDP values, the performance statistics of the VM and the configuration of the VM.

Initially, the communication between the existing network and the proposed network of the migrated VM is assessed. For assessing the communication, the system logs ping statistics for each interface of the VM prior to the migration of the VM. Thereafter, the ping results prior to the migration are compared with the ping results obtained after the migration. Here, all interfaces of the VM are not accessible to the ping results due to network Internet Control Message Protocol (ICMP) configurations and virtual Local Area Network (VLAN) limitations. Therefore, the syste...
