MAC Multicast Support
Multicast service is a limited broadcast service, which allows one-
to-many and many-to-many connections for information distribu-
tion. Layer 2 Multicast service is where a single frame is
addressed to a specific Multicast address, from where copies of
the frame are transmitted to the relevant ports.
MDI/MDIX Support
The device automatically detects whether the cable connected to
an RJ-45 port is crossed or straight through, when auto-negotia-
tion is enabled.
Standard wiring for end stations is Media-Dependent Interface
(MDI) and the standard wiring for hubs and switches is known as
Media-Dependent Interface with Crossover (MDIX).
Multiple Spanning Tree
Multiple Spanning Tree (MSTP) operation maps VLANs into STP
instances. MSTP provides differing load balancing scenario.
Packets assigned to various VLANs are transmitted along differ-
ent paths within MSTP Regions (MST Regions). Regions are one
or more MSTP bridges by which frames can be transmitted. The
standard lets administrators assign VLAN traffic to unique paths.
Password Management
Password management provides increased network security and
improved password control. Passwords for SSH, Telnet, HTTP,
HTTPS, and SNMP access are assigned security features. For
more information on Password Management, see “Configuring
Passwords“.
Port Based Authentication
Port based authentication enables authenticating system users
on a per-port basis via an external server. Only authenticated and
approved system users can transmit and receive data. Ports are
authenticated via the Remote Authentication Dial In User Service
(RADIUS) server using the Extensible Authentication Protocol
(EAP).
Port Based Virtual LANs
Port-based VLANs classify incoming packets to VLANs based on
their ingress port.
Port Mirroring
Port mirroring monitors and mirrors network traffic 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 traffic passing through a specified source port.
