DESCRIPTION
An IP interface (also known as an IP routing domain) is not bound to a
physical port. Configure an IP routing domain to allow the switch to route
traffic between different networks.
A VLAN (Virtual Local Area Network) allows a physical network to be
partitioned into multiple logical networks. Devices on a logical network
belong to one group. A device can belong to more than one group. With
VLAN, a device cannot directly talk to or hear from devices that are not in
the same group(s); the traffic must first go through a router.
Use VLAN stacking to add an outer VLAN tag to the inner IEEE 802.1Q
tagged frames that enter the network. By tagging the tagged frames
("double-tagged" frames), the service provider can manage up to 4,094
VLAN groups with each group containing up to 4,094 customer VLANs.
This allows a service provider to provide different service, based on
specific VLANs, for many different customers.
Filter traffic based on the source and/or destination MAC address and
VLAN group (ID).
Use this feature to have the MM-7201 assign IP addresses, an IP default
gateway and DNS servers to computers on your network.
The switch supports IGMP snooping enabling group multicast traffic to
be only forwarded to ports that are members of that group; thus allowing
you to significantly reduce multicast traffic passing through your switch.
With DiffServ, the switch marks packets so that they receive specific per-
hop treatment at DiffServ-compliant network devices along the route
based on the application types and traffic flow.
You can create a policy to define actions to be performed on a traffic flow
grouped by a classifier according to specific criteria such as the IP
address, port number or protocol type, etc.
Queuing is used to help solve performance degradation when there is
network congestion. Two scheduling services are supported: Strict
Priority Queuing (SPQ) and Weighted Round Robin (WRR). This allows
the switch to maintain separate queues for packets from each individual
source or flow and prevent a source from monopolizing the bandwidth.
Port mirroring allows you to copy traffic going from one or all ports to
another or all ports in order that you can examine the traffic from the
mirror port (the port you copy the traffic to) without interference.
Static routes tell the switch how to forward IP traffic when you configure
the TCP/IP parameters manually.
Port cloning allows you to copy attributes from one port to another port or
ports.
Multicast VLAN Registration (MVR) is designed for applications (such as
Media-on-Demand (MoD)) using multicast traffic across a network. MVR
allows one single multicast VLAN to be shared among different
subscriber VLANs on the network.
This improves bandwidth utilization by reducing multicast traffic in the
subscriber VLANs and simplifies multicast group management.
With IP multicast, the switch delivers IP packets to a group of hosts on
the network - not everybody. In addition, the switch can send packets to
Ethernet devices that are not VLAN-aware by untagging (removing the
VLAN tags) IP multicast packets.
RIP (Routing Information Protocol) allows a routing device to exchange
routing information with other routers.
