I need to be able to mirror traffic from 4 ports on Cisco Nexus 3000 switch to 2 ports on a same switch and connect 2 IPS appliances to those 2 ports. But I don't think it is possible to mirror port to 2 ports on Nexus devices, Any advice in how to solve this?
I'm afraid that is not possible to do this directly on the Nexus, since:
- only one destination port is allowed in a monitor configuration
- the same source port cannot be set in two different sessions.
- the destination port of a session cannot be set as the source port of another session.
Some IOS based switches allow this configuration (with 2 destination ports), so if you have such switches with ports available you could do it. Obviously it increases the cost and number of ports required.
