Configuring the Switch



24-Port 10/100 + 4-Port Ggabt Swtch wth WebVew and Power over Ethernet

Exceed Acton

Specifies whether the traffic that

exceeds the specified rate or burst will be dropped or
the DSCP service level will be reduced .

Set

Decreases DSCP priority for out of conformance

traffic . (Range: 0-63) .

Drop

Drops non-conforming traffic .

Add

Adds the specified criteria to the policy map .

Remove

Deletes a class from a policy .

Add classes to a selected policy and set the Action, Meter,
Rate, Burst and Exceed values using the drop-down menus
and fields provided then click Add .

QoS > DiffServ Port Binding

This function binds a policy map to the ingress queue of
a particular interface . You must first define a class map,
set an ACL mask to match the criteria defined in the class
map, then define a policy map, and finally bind the service
policy to the required interface . You can only bind one
policy map to an interface . The current firmware does not
allow you to bind a policy map to an egress queue .

Check the checkbox and choose a Policy Map for a port
from the drop-down menu .

Click Save Settngs to save the changes .

QoS > Bandwidth

This function allows the network manager to control 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 coming out of the Switch .
Traffic that falls within the rate limit is transmitted, while
packets that exceed the acceptable amount of traffic are
dropped .

Rate limiting can be applied to individual ports or
LAGs . When an interface is configured with this feature,
the traffic rate will be monitored by the hardware to
verify conformity . Non-conforming traffic is dropped,
conforming traffic is forwarded without any changes .

QoS > Bandwidth

Port

Displays the port or LAG number .

Status

Enables the rate limit (input or output) for the port

or LAG . (Default: Disabled)

Rate Lmt (Kbts/sec)

Sets the rate limit level for the

port or LAG . For Fast Ethernet ports the default is 100000
Kbits/sec (Range: 64-100000) . For Gigabit Ethernet ports
the default is 1000000 Kbits/sec (Range: 64-1000000) .

LAG

Indicates if ports are members of a LAG . To configure

a rate limit for LAGs, go to the table entry for the LAG
number, which is listed after ports Gig 1 and Gig 2 at the
end of the table .

Set the Input Rate Limit Status or Output Rate Limit Status,
then set the rate limit for individual interfaces or LAGs,
then click Save Settngs .

Spanning Tree

The Spanning Tree Algorithm (STA) can be used to detect
and disable network loops, and to provide backup links
between switches, bridges or routers . This allows the
Switch to interact with other bridging devices (that is, an
STA-compliant switch, bridge or router) in your network
to ensure that only one route exists between any two
stations on the network, and provide backup links which
automatically take over when a primary link goes down .
