When the Magnum 6KM Switch detects that its free buffer queue space is low,
the Switch sends industry standard (full-duplex only) PAUSE packets out to the devices
sending it packets to cause “flow control”. This tells the sending devices to temporarily
stop sending traffic, which allows the traffic to catch-up without dropping packets. Then,
normal packet buffering and processing resumes. This flow-control sequence occurs in a
small fraction of a second and is transparent to an observer.
Another feature implemented in the Magnum 6KM Switches is a collision-
based flow-control mechanism (when operating at half-duplex only). When the Switch
detects that its free buffer queue space is low, the Switch prevents more frames from
entering by forcing a collision signal on all receiving half-duplex ports in order to stop
incoming traffic.
2.3 Managed Network Software for Magnum 6KM
Magnum 6KM comes with licensed MNS-6K software or MNS-6K-SECURE, which
allow the user to configure the Magnum 6KM as a Managed Switch and implements
security features and other software enabled features.
(NOTE: Magnum 6KM managed switch will work with MNS-6K Rel v4.1.9
firmware or higher version only, or MNS-6K-SECURE v14.1.9 firmware or higher
version only. Using any earlier MNS-6K versions will not support the 6KM
hardware)
