RSTP – rapid spanning tree protocol
Spanning Tree can take 30...60 seconds for each host to decide
whether its ports are actively forwarding trafc. Rapid Spanning Tree
(RSTP) detects uses of network topologies to enable faster conver-
gence, without creating forwarding loops.
Port mirroring
Port mirroring monitors and mirrors network trafc by forwarding copies
of incoming and outgoing packets from a monitored port to a monitoring
port. Users specify which target port receives copies of all trafc passing
through a specied source port.
Link aggregation (trunking)
MPH200 Ethernet Switch supports ingress and egress port aggregation
in accordance with IEEE Std 802.3ad. Any number of ports can be
aggregated into any number of groups. Frames are distributed among
the aggregated ports by an advanced frame distribution function, which,
through conguration, can use the following information:
• Source and destination MAC addresses
• Source and destination IP addresses
• TCP/UDP port numbers for IPv4 packets
• Flow label for IPv6 packet
• Pseudo-randomization.
LACP – link aggregation control protocol
LACP uses peer exchanges across links to determine, on an ongoing
basis, the aggregation capability of various links, and continuously
provides the maximum level of aggregation capability achievable
between a given pair of systems. LACP automatically determines,
congures, binds and monitors the port binding within the system.
802.1X – port-based network access control
The port-based network access standard IEEE Std 802.1X provides a
framework to implement port authentication where only authenticated
ports have access to the network. Ports are initially in an unauthorized
state where normal frame forwarding for the port is disabled. The port
only accepts special authentication frames. Upon authorization, the
network services become enabled for the port, and normal frame
forwarding is possible. The authentication is initiated by extensible
authentication protocol over LAN (EAPOL) frames, which are identied
by the unique bridge group address 01-80-C2-00-00-03.
