IP Routing Domain

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.

 

 

VLAN

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.

 

 

VLAN Stacking

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.

 

 

MAC Address Filter

Filter traffic based on the source and/or destination MAC

 

address and VLAN group (ID).

 

 

DHCP (Dynamic Host

Use this feature to have the Switch assign IP addresses, an IP

Configuration Protocol)

default gateway and DNS servers to computers on your

 

network.

 

 

IGMP Snooping

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.

 

 

Differentiated Services

With DiffServ, the Switch marks packets so that they receive

(DiffServ)

specific per-hop treatment at DiffServ-compliant network

 

devices along the route based on the application types and

 

traffic flow.

 

 

Classifier and Policy

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

Queuing is used to help solve performance degradation when

 

there is network congestion. Three scheduling services are

 

supported: Strict Priority Queuing (SPQ), Weighted Round

 

Robin (WRR) and Weighted Fair Queuing (WFQ). 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

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 Route

Static routes tell the Switch how to forward IP traffic when you

 

configure the TCP/IP parameters manually.
