84 Configuring & Monitoring the Switch
VH-2402S2
•
To disable a single link within a port trunk, you should first remove the
network cable, and then disable both ends of the link via the
configuration menu. This allows the traffic passing across that link to
be automatically distributed to the other links in the trunk, without
losing any significant amount of traffic.
Configuring Broadcast Storm Control
The VH-2402S2 switch supports a broadcast control mechanism that
prevents a high level of broadcast traffic from overwhelming the network.
When enabled for a switch stack, the system monitors the level of
broadcast traffic that passes through all ports in the stack. If the broadcast
traffic level rises above the specified packet-per-second threshold, the
broadcast-control mechanism will be employed.
1.
Select Device Control Menu from the Main Menu.
2.
Select BStorm Control Configuration and press [Enter].
3.
Highlight the Threshold field and enter the packet-per-second
threshold at which broadcast control will be employed (default is 200
pps).
4.
Highlight the Averaging Interval field and set the time period for which
the control mechanism will be active (200 ms, 500 ms, 1, 5, or 10
seconds; default is 1 second).
5.
Highlight the Broadcast Control field and select ENABLED.
6.
Select <APPLY> and press [Enter].
The broadcast control mechanism drops all broadcast packets from the
stack for the specified time period. The control mechanism will be
continuously re-activated after each time period until the number of
received broadcasts falls back below the packet-per-second threshold.
Saving and Restoring the Switch Configuration
After completing your switch configuration, you can save all the settings
to a file on a TFTP server. This file can be later downloaded to the switch
to restore the switch’s settings.
To save a configuration file to a TFTP sever, do the following:
1.
From the console interface Main Menu, select Management Setup
Menu and then Configuration Save & Restore.
2.
Select Upload Server IP Address under the section Configuration
Upload.
3.
Enter the TFTP server IP address and press [Enter].
4.
Select Upload Filename and enter the file name to be uploaded to the
TFTP server.
5.
Select Process TFTP Upload and press [Enter
