To configure the static Bootp relay setup

		Using the Web Console

	Field	Description

		Sets the maximum number of hops (routers) that the BOOTP
	BOOTP Hops Count Limit	messages can be relayed through. If a packet's hop count is
	BOOTP Hops Count Limit	more than the hop count limit, the packet is dropped. The
		more than the hop count limit, the packet is dropped. The
		range is between 1—16 hops. The default value is 4.

		Sets the minimum time (in seconds) that the switch will wait
		before forwarding a BOOTREQUEST packet. If the value in
	BOOTP/DHCP Relay Time Threshold	the seconds field of the packet is less than the relay time
		threshold, the packet will be dropped. The range is between
		0—9999 seconds. The default value is 0 seconds.

4. Click Apply.

To configure the static BOOTP relay setup

You must configure the BOOTP/DCHP relay agent so that it knows the servers’ IP addresses and subnet names (IP interface names).

1.In the left panel, click Switch Utilities.

2.In the top panel under Others, click BOOTP/DHCP Relay Interface Configurations.

3.Click New and configure these fields.

	Field	Description

	Interface Name	Specifies the subnet name (IP interface name) of the network that the
	Interface Name	BOOTP or DHCP server is located on.
		BOOTP or DHCP server is located on.

	BOOTP/DHCP Server	Specifies the IP address of the BOOTP or DHCP server. Multiple servers
	BOOTP/DHCP Server	may be entered for a given subnet name (IP interface name).
		may be entered for a given subnet name (IP interface name).

4.Click Apply.

The server is added to the BOOTP/DHCP Relay Setup list.

5.To add another server, repeat steps 2 and 3. Each IP interface can be configured for four servers.

6.To remove a server, select the server and click Delete.

DNS Relay

DNS relay enables the switch to act as a DNS cache or proxy and to forward DNS requests to the DNS server only when required. Whether you enable DNS relay depends upon whether you want to

•Save a DNS server or the linking WAN extraneous or repetitive traffic.

•Try to shorten the response time for a DNS request on a slow or long WAN.

•Change or control the IP response for a series of DNS requests.

•Control which servers are used for DNS.

When the switch receives packets destined for a DNS server and the requests are not statically defined in the switch or previously cached, the switch forwards them to the servers as defined in the following configuration. The switch also forwards packets from the DNS servers back to the appropriate subnets.
