ACLs provide packet filtering for IP frames (based on protocol, TCP/UDP
port number or frame type) or layer 2 frames (based on any destination
MAC address for unicast, broadcast or multicast, or based on VLAN ID or
VLAN tag priority). ACLs can by used to improve performance by blocking
unnecessary network traffic or to implement security controls by restricting
access to specific network resources or protocols. Policies can be used to
differentiate service for client ports, server ports, network ports or guest
ports. They can also be used to strictly control network traffic by only
allowing incoming frames that match the source MAC and source IP on
specific port.

ONFIGURATION
You can manually configure the speed and duplex mode, and flow control
used on specific ports, or use auto-negotiation to detect the connection
settings used by the attached device. Use the full-duplex mode on ports
whenever possible to double the throughput of switch connections. Flow
control should also be enabled to control network traffic during periods of
congestion and prevent the loss of packets when port buffer thresholds are
exceeded. The switch supports flow control based on the IEEE 802.3x
standard (now incorporated in IEEE 802.3-2002).

IMITING
This feature controls the maximum rate for traffic transmitted or received
on an interface. Rate limiting is configured on interfaces at the edge of a
network to limit traffic into or out of the network. Traffic that falls within
the rate limit is transmitted, while packets that exceed the acceptable
amount of traffic are dropped.

IRRORING
The switch can unobtrusively mirror traffic from any port to a monitor port.
You can then attach a protocol analyzer or RMON probe to this port to
perform traffic analysis and verify connection integrity.

RUNKING
Ports can be combined into an aggregate connection. Trunks can be
manually set up or dynamically configured using Link Aggregation Control
Protocol (LACP – IEEE 802.3-2005). The additional ports dramatically
increase the throughput across any connection, and provide redundancy by
taking over the load if a port in the trunk should fail. The switch supports
up to 14 trunks.

ONTROL
Broadcast, multicast and unknown unicast storm suppression prevents
traffic from overwhelming the network.When enabled on a port, the level of
broadcast traffic passing through the port is restricted. If broadcast traffic
rises above a pre-defined threshold, it will be throttled until the level falls
back beneath the threshold.

A static address can be assigned to a specific interface on this switch.
Static addresses are bound to the assigned interface and will not be
