I have the following network setup: 2 network elements connected together with an OC3/STM1 link. In beween there is an OC3/STM1 network tap that mirrors the traffic. My question is now: is it possible to put this (passiv) link into a Cisco switch and e.g. mirror it to different ethernet ports. Especially does Cisco keep OC3/STM1 links up that do not have any active handshaking or keep alive signaling (port is not allowed/able to send any data into the network).
I have this problem too.
