312 APPENDIX A: DEVICE SPECIFICATIONS AND FEATURES
MAC Multicast Support Multicast service is a limited broadcast service, which allows
one-to-many and many-to-many connections for information
distribution. 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-negotiation 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 different 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 “Managing
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.
