Number of Login Accounts
Configurable on the Switch
4 management accounts configured on the Switch.
Authentication via RADIUS and TACACS+ also available.
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
Configuration Protocol)
Use this feature to have the Switch assign IP addresses, an IP 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
(DiffServ)
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.
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.
