Configuring & Monitoring The Switch 63
Configuring Broadcast Cutoff Rate
This setting affects the throttling of excessive broadcast or unicast
packets with unknown MAC addresses being handled by the switch.
Normally, when these types of packets are received by the switch, they
are forwarded (flooded) to every port on the switch or on a VLAN.
However, if the receiving rate of these packets exceeds the broadcast
cutoff rate, the switch will throttle back or limit the forwarding of these
packets based on the configured Broadcast Cutoff Rate. This mechanism
helps to prevent broadcast storms, a problem often encountered in
Ethernet networks.
To configure the broadcast cutoff rate, do the following:
1.
Select Switch Configuration Menu from the Main Menu.
2.
Select Broadcast Cutoff Rate, enter the rate value, and press [Enter].
Valid values are in the range from 100 to 500,000 per second. This
rate value is applied to each grouping of 8 10/100 ports and each Gi-
gabit Ethernet port on the switch. A setting of 500,000 essentially dis-
ables this feature.
Setting a Default Gateway
The Default Gateway parameter defines the IP address of a router or
other network device to which IP packets are to be sent if destined for a
subnet outside of that which the switch is operating.
To set a default gateway, do the following:
1.
Select System Configuration Menu from the Main Menu.
2.
Select Default Gateway.
3.
Enter the gateway IP address. Press [Enter].
Configuring BootP/DHCP
The DHCP and BootP protocols allow you to automatically configure the
switch’s IP address information. Enabling this feature greatly speeds up
device configuration, especially when a large number of devices are
installed.
A DHCP and/or BootP server must be operating on the network and be
properly configured for this option to work. When this option is enabled,
the switch first tries to obtain an IP address from a DHCP server. If this
fails, the switch tries to obtain an IP address from a BootP server. If this
fails, the switch uses a previously configured IP address, if one exists.
To configure BootP/DHCP, do the following:
1.
Select System Configuration Menu from the Main Menu.
2.
Select BootP/DHCP Enable.
This selection toggles between Enable and Disable.
