We have deselected Preserve original VLAN. In this example we have configured VLAN 400 as RSPAN VLAN or “Encapsulation VLAN ID”. The next step in the configuration process is enabling the port mirror session status, providing VLAN ID for RSPAN traffic, and selecting or deselecting the preserve original VLAN option. I will talk about that deployment in the part 3 of this series. RSPAN configuration – screen1Īccording to the configuration screen above, VDS switch can also act as the destination for the RSPAN session by selecting “Remote Mirroring Destination”. As shown in the diagram below, select “Remote Mirroring Source” and configure the source of the RSPAN session. We will now go through the steps of configuring a remote mirroring (RSPAN) session on VDS. Since RSPAN end to end mirror session configuration requires physical switch support, users should look at the physical switch vendor’s documentation for guidelines and any limitation of RSPAN feature. The S2 switch port where Analyzer is connected acts as RSPAN destination.Ĥ) Analyzer – Device where packet analysis is performed. S1 is not RSPAN source or destination switch.ģ) S2 – Physical switch is destination switch. Let’s briefly take a look at the main components of the RSPAN session as shown in the above diagram.ġ) VDS – VDS is called as source switch because RSPAN source of the port mirroring session is on this virtual switch.Ģ) S1 – Physical switch is intermediate switch. A dedicated RSPAN VLAN is defined to carry the port mirror traffic. You have to configure RSPAN session on VDS and also configure RSPAN VLAN on physical switches. The RSPAN port mirroring session configuration is little more involved when compared to SPAN setup. The analyzer tool can be connected multiple hops away in a network as shown in the diagram below. The Remote SPAN (RSPAN) port mirroring session addresses above concerns and also provides the capability to send mirror traffic to a central analyzer tool. – If the monitored virtual machine is moved from one host to another using vMotion, you can’t monitor that virtual machine traffic anymore.

Thus limiting the visibility to a particular host. – The source and destination ports of the session should be on the same host. However, SPAN on VDS has following limitations SPAN is a simple configuration on VDS that allows users to quickly replicate traffic to another virtual machine on the same host. In the last post I covered the configuration of one of the port mirroring session type, Switch Port Analyzer (SPAN) on a host.
