Dynamic Tasking Control Protocol under IOS
Juniper routers support Dynamic Tasking Control Protocol(DTCP) in case hardware requirements are met. DTCP is used for lawful intercept. Somewhat similar to RSPAN in case of Cisco, but allows one to specify filters for traffic, different organizations can specify rules for DTCP and tapping sessions are separated. Is there something similar under Cisco routers/switches as well? Or is the RSPAN closest to flow-tap on Juniper routers?
