Chapter Configuration Using the Web-based Utility
1 24/48-Port 10/100 + 4-Port Gigabit Resilient Clustering Smart Switch with 2 Combo SFPs
Security > Storm Control
The Storm Control screen is used to configure broadcast
and multicast storm control.
Security > Storm Control
Storm Control enables limiting the amount of Multicast and
Broadcast frames accepted and forwarded by the Switch.
A Broadcast Storm results when an excessive amount of
broadcast messages is simultaneously transmitted across
a network by a single port. Forwarded message responses
are heaped onto the network, straining network resources
or causing the network to time out.
To enable Storm Control on a port, you specify the packet
type (broadcast/multicast) and maximum transmission
rate. The system measures the incoming Broadcast and
Multicast frame rates separately on each port and discards
frames when the rate exceeds the specified maximum.
Interface Select the unit number and port from which
storm control is enabled.
Broadcast Control Select the checkbox to apply
Broadcast control on the selected interface. Broadcast
control limits the amount of Broadcast packet types to be
forwarded. The default is not selected (disabled).
Mode Specifies the Broadcast mode currently enabled
on the device. The possible values are:
Multicast & Broadcast Counts Broadcast and
Multicast traffic together.
Broadcast Only Counts only Broadcast traffic.
Rate Threshold The maximum rate (packets per second)
at which unknown packets are forwarded. The ranges are
0 kbps to 100 Mbps for FE ports, and . to 100 Mbps
for GE ports. The default value is 00 kbps.
The Update button adds the Storm Control settings to the
Storm Control table at the bottom of the screen.

Security > RADIUS
The RADIUS screen is used to configure a Remote
Authorization Dial-In User Service (RADIUS) server for user
authentication.
Security > RADIUS
RADIUS servers provide additional security for networks
by providing a centralized authentication method for web
access. Up to eight RADIUS servers can be configured. The
Switch attempts authentication using the listed sequence
of servers. The process ends when a server either approves
or denies access to a user.
IP Address Enter the IP address of the authentication
server.
Priority The server priority. The possible values are 0
to , where 0 is the highest priority. This priority
determines the order in which RADIUS servers are queried
when more than one RADIUS server is configured. The
default priority is 0.
Authentication Port Enter the authentication port. The
authentication port is used to verify the RADIUS server
authentication. The default value is 1812.
Number of Retries Defines the number of transmitted
requests sent to RADIUS server before a failure occurs. The
possible values are 1 to 10. The default is .
Timeout for Reply Defines the amount of the time in
seconds the device waits for an answer from the RADIUS
server before retrying the query, or switching to the next
server. The possible values are 1 to 0. The default is .
Dead Time Defines the amount of time (minutes) that a
RADIUS server is bypassed for service requests. The range
is 0 to 2000. The default is 0 minutes.
Key String Defines the default key string used to
authenticate and encrypt all RADIUS communications
between the device and the RADIUS server. This key must
match the RADIUS encryption.
Source IP Address Defines the source IP address that is
used for communication with RADIUS servers.
