LAN - Uni-direction Receive Only

[avilt]

I need to aggregate SPAN ports from multiple network segments into a single switch with uni-direction cable.

Example. I have three independent/isolated three networks LAN-A, LAN-B & LAN-C.

I need to take SPAN port from all three network and put it into one new switch which will be connected to an Anomaly detection system. However I have to ensure (guaranty) that no data/traffic from each segments (LAN-A, LAN-B & LAN-C) leaks into other.

Can I achieve this by removing transmit pair cable (inside RJ45 Jack) from the SPAN ports of all ports connecting to new switch?

Suggest to Look RSPAN : ( i do not believe you need any speacial cable, on the receiver end) - just look at the document and steps. - make sure devices support feature most does. but worth checking.
