Description
Samurai-6M/6MX (ADM6996M/MX) locks the first SA+FID of packets received on the
port. After the first (SA+FID) is locked, Samurai-6M/6MX (ADM6996M/MX) starts to
check packets with different (SA+FID).
1. If the packets are not assigned as management, drop it (modify the forwarding
2. If the packets are management packets, and Source Violation (see 000B
3. If the packets are management packets and Source Violation is configured to 0
The first received packets will be locked as First Lock. The difference is that the
receiving port will not receive and learn packets any more after the port links down
even if it links up again. A source violation is recorded as the First Lock. If Samurai-
6M/6MX (ADM6996M/MX) modifies the forwarding algorithm it is still as the First Lock.
Samurai-6M/6MX (ADM6996M/MX) allows users to assign the locked SA+FID through
CPU’s help instead of the first SA+FID. A source violation is recorded as the First Lock.
If Samurai-6M/6MX (ADM6996M/MX) modifies the forwarding algorithm it is still as the
First Lock.
Samurai-6M/6MX (ADM6996M/MX) allows users to assign the locked SA+FID through
CPU’s help instead of the first SA+FID. The others are the same as the First Link Lock.
The “unknown source address” means that (SA+FID) is not found in the learning table
or even is found but Portmap doesn’t match the incoming port. If “unknown” packets
are received, Samurai-6M/6MX (ADM6996M/MX) records the source violation as the
First Lock. The rule to modify the forwarding algorithm is still as the First Lock.
This option is the same as “Discard Unknown” except that if Samurai-6M/6MX
(ADM6996M/MX) decides to modify the forwarding algorithm, it will forward the
packets to the CPU port instead of dropping them.
If the incoming port receives the packets with SA, marked as Source Intrusion, we
handle these packets in the following rule:
1. Enabled Source Intrusion Must (see 000B
2. If Source Intrusion Must is not enabled, Samurai-6M/6MX (ADM6996M/MX) also
3. If Source Intrusion Must is not enabled, Samurai-6M/6MX (ADM6996M/MX) also
4. If Source Intrusion Must is not enabled, Samurai-6M/6MX (ADM6996M/MX)
Samurai-6M/6MX (ADM6996M/MX) allows the users to redirect the packets to the
CPU port instead of dropping it when they violate the source intrusion (see Source
Intrusion Action in 000B
algorithm) and record it as a source violation.
Control Register
6M/6MX (ADM6996M/MX) modifies the forwarding algorithm to drop these
packets. They are also recorded as a source violation.
then Samurai-6M/6MX (ADM6996M/MX) doesn’t modify the forwarding algorithm.
In this situation, we don’t record this case as a source violation.

violation always.
