Samurai-6M/6MX (ADM6996M/MX) supports stricter security protection. The port is disabled when there is a
source violation. Enable Security Option[3] to enable this feature.
3.1.20
Samurai-6M/6MX (ADM6996M/MX) identifies packet headers and transfers it from the incoming port to the
destination ports.
3.1.20.1
Samurai-6M/6MX (ADM6996M/MX) provides a control table for user to control the forwarding algorithm of the DA
= 01 80 C2 00 00 00
3.1.20.2
The default output ports that a packet is transferred to are determined in the following order.
1. The Portmap in the Special Tag with Portmap_Valid = 1 is used as the output ports.
2. The Portmap in the learning table is used as the output ports, when (DA+FID) matches an entry in the learning
3. The Portmap in the hardware IGMP table is used as the output ports, when DA matches an entry in the
4. “Broadcast Portmap” (see 001A
5. “Multicast Portmap” (see 001B
6. “Unicast Portmap” (see 0019
