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. The following 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.
Bandwidth Control Bandwidth control means defining a maximum allowable
bandwidth for incoming and/or out-going traffic flows on a port.
Broadcast Storm Control Broadcast storm control limits the number of broadcast,
multicast and destination lookup failure (DLF) packets the
Switch receives per second on the ports.
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.
Two Rate Three Color
Marker
Two Rate Three Color Marker (trTCM, defined in RFC 2698) is a
type of traffic policing that identifies packets by comparing
them to two user-defined rates: the Committed Information
Rate (CIR) and the Peak Information Rate (PIR).
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 allow the Switch to communicate with
management stations not reachable via the default gateway.
Multicast VLAN
Registration (MVR)
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.
IP Multicast 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.
STP (Spanning Tree
Protocol) / RSTP (Rapid
STP)/MSTP (Multiple
Spanning Tree Protocol)
(M)(R)STP detects and breaks network loops and provides
backup links between switches, bridges or routers. It allows a
Switch to interact with other (M)(R)STP-compliant switches in
your network to ensure that only one path exists between any
two stations on the network.
Loop Guard Use the loop guard feature to protect against network loops on
the edge of your network.
IP Source Guard Use IP source guard to filter unauthorized DHCP and ARP
packets in your network.
