Step 4. A. You can use switched port analyzer (SPAN) in order to analyze network traffic that passes through ports or VLANs of the switch, which send a copy of the traffic to a destination port where the network analyzer connects to the switch. In order to extend SPAN, RSPAN enables remote monitoring of multiple switches across your network. In the VLAN ID field, enter the VLAN identifier for the RSPAN VLAN header. Switch2(config-vlan)# remote-span. Cisco Logging Configuration Examples. A SPAN destination port ceases to act as a normal switch port. configuration example uses source ports on two different Nexus 7000 series switches and a destination port on one Nexus 7000 switch where the network analyzer has connected. Currently I am recording voice on 8 Ip-Phones via sniffing of those 8 ports on a 3560 and sending those packets to a server (on the same switch) that uses sniffing for recording, no problem here. Step 6: no monitor session {session_number | all | local | remote} Example: Device(config)# no monitor session 1: Removes any existing SPAN configuration for the Create an RSPAN VLAN on the source switch, destination switch, and all switches in the transit path. In this example, the source port is the port connected to the server (Gi0/1) and the destination port is the port attached to the packet analyzer (Fa0/7). It won't work, Do note the limitations on the EX3200/4200 and EX8200 using SPAN. VPN: IPsec (interface based/vti), IPsec (policy-based) VRRPv2/v3. Step2: Then configure the RSPAN on Source switch: Unlike SPAN, where the source and destination ports exist on the same switch, the source and destination ports for an RSPAN session reside on different switches. RSPAN takes our SPAN configuration from earlier and works across a dedicated VLAN tunnel. cisco monitor session configuration example. In this example we'll be mirroring traffic from an IP phone connected to an access switch, over to a server connected to an upstream switch. Configuration. RSPAN stands for Remote Span (Switched Port Analyzer).
