Linux UCT-V Installation

Refer to the following sections for Linux agent installation:

Single vNIC Configuration

A single NIC/vNIC acts both as the source and the destination interface. A UCT-V with a single NIC/vNIC configuration lets you monitor the ingress or egress traffic from the NIC/vNIC. The monitored traffic is sent out using the same NIC/vNIC.

For example, assume that there is only one interface eth0 in the monitoring VM. In the UCT-V configuration, you can configure eth0 as the source and the destination interface, and specify both egress and ingress traffic to be selected for monitoring purpose. The egress and ingress traffic from eth0 is mirrored and sent out using the same interface.

Note:  Using a single NIC/vNIC as the source and the destination interface may cause increased latency in sending the traffic out from the VM.

Example of the UCT-V config file for a single NIC/vNIC configuration:

Grant permission to monitor ingress and egress traffic at iface 

            # eth0   mirror-src-ingress mirror-src-egress mirror-dst

Multiple vNICs Configuration

A UCT-V lets you configure multiple vNICs. You can:

  • Configure one or many vNICs as the source interface.

  • Send out the monitored traffic using one of the vNICs or a separate, non-monitored vNIC.

Example: eth0 and eth1 in the monitoring instance.

In the UCT-V configuration,

  • Configure eth0 as the source interface.

  • Select egress traffic for monitoring purpose.

  • Configure eth1 interface as the destination interface.

  • The mirrored traffic from eth0 is sent to eth1.

  • From eth1, the traffic is sent to the GigaVUE V Series node.
