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.
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.
