I have two switches connected with etherchannel. Between them, trunking is done with dot1q. On both switches there are three VLAN-s: 1, 100 and 200. Switches are Cisco 3560. Can I somehow monitor all traffic from all ports in VLAN1 from switch1 and all ports in VLAN1 from switch2 and send all of that traffic to one port on switch1 (i.e. f0/10 on switch1)?
both switches have this VLAN 1, and I believe that the etherchannel trunk allows vlan 1 go through , correct?
In that case its a simple job.
VLAN-based SPAN (VSPAN) is the monitoring of the network traffic in one or more VLANs. The SPAN or RSPAN source interface in VSPAN is a VLAN ID, and traffic is monitored on all the ports for that VLAN.
VSPAN has these characteristics:
?All active ports in the source VLAN are included as source ports and can be monitored in either or both directions.
?On a given port, only traffic on the monitored VLAN is sent to the destination port.
?If a destination port belongs to a source VLAN, it is excluded from the source list and is not monitored.
?If ports are added to or removed from the source VLANs, the traffic on the source VLAN received by those ports is added to or removed from the sources being monitored.
?You cannot use filter VLANs in the same session with VLAN sources.
VSPAN already works on the equipment. The problem is that currently SPAN is only monitoring all ports in VLAN1 on the switch1 and all the traffic is sent to fastethernet0/10 on SW1. Ports in switch2 that belongs to VLAN1 are not monitored. Is there something else to enter on SW2 to force all ports in VLAN1 on SW2 to reflect it's traffic to fastethernet0/10 on SW1?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
