On all M Series, T Series, and MX Series routers, you can send a copy of an IPv4 or IPv6
packet from the routers to an external host address or a packet analyzer for analysis.
This is known as port mirroring. In addition, on the M7i, M10i, M120, M320 and MX Series
routers only, you can configure port mirroring for VPLS traffic. VPLS port mirroring is
supported only on M7i and M10i routers with Enhanced CFEB (CFEB-E). In addition, on
M320 routers, VPLS port mirroring is supported only on Enhanced III Flexible PIC
Concentrators (FPCs).
