SPAN sessions do not interfere with the normal operation of the device. However, an oversubscribed SPAN destination, for example, a 10-Mb/s port monitoring a 100-Mb/s port, can result in dropped or lost packets.SPAN is only supported on physical ports; SPAN is not supported on logical interfaces such as VLANs or EFPs. SPAN is not supported on port channels. Up to 15 active SPAN sessions (ingress and egress) are supported. The switch supports up to 15 ingress sessions and up to 12 egress sessions. You can have one SPAN destination interface.A source port is a port monitored for traffic analysis. You can configure both switched and routed ports as SPAN source ports. SPAN can monitor one or more source ports in a single SPAN session. You can configure source ports in any VLAN. Trunk ports can be configured as source ports and mixed with nontrunk source ports.Symptom: If in a span session we have more than one SPAN source ports on the same switch (can be either a standalone switch or a member in a stack of switches) it is observed that only traffic from one of the two ports is being captured. No traffic is captured on the other ports.The source interface can be anything…switchport, routed port, access port, trunk port, etherchannel, etc. When you configure a trunk as the source interface it will copy traffic from all VLANs, however there is an option to filter this. You can use multiple source interfaces or multiple VLANs, but you can't mix interfaces and VLANs.Cisco Nexus Data Broker The Cisco Nexus 3500 platform switches with Cisco Nexus Data Broker can be used to build a scalable and cost- effective traffic monitoring infrastructure using network taps and SPAN.

If a destination port is oversubscribed, it can become congested. This congestion can affect traffic forwarding on one or more of the source ports. Must be on the same host (line card) as the source port. In Local SPAN, the source interface and destination ...A switch stack basically works like a single switch with a single configuration, much like a chassis switch with multiple blades. You would configure SPAN the same way you do on a single switch. You can set up all the traffic to go to a single monitor port on any of the switches, although you could easily overload the single port and drop a lot ...ALso note that VLAN 1000 does not exist anywhere else on the network, and is at this point not in play; the access switchport configs were deleted in an attempt to use standard SPAN instead, though neither mechanism works. (VLAN 1000 was used as a straight switch-internal-only VLAN to try and trick the system to pass the packets in untagged from from the Nexuses to the port where the ...The problem is I have a server on switch (1) and 4 ports I need to monitor on the same switch (1)and use as destination of the span the port of the server (connected to switch 1).
