To configure DNS Relay services

Using the Telnet Console

2. Configure these fields.

	Field	Description

	BOOTP/DHCP Relay Status	Enables or disables the BOOTP/DHCP relay function.

		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 request packet. If the value in the
	BOOTP/DHCP Relay Time Threshold	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.

3.Highlight APPLY and press Enter.

4.If you enabled BOOTP/DHCP Relay, highlight BOOTP/DHCP Relay Interface Configuration and press Enter.

5.Toggle the Action field to Add 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 relay server. Multiple
	BOOTP/DHCP Server	servers may be entered for a given subnet name (IP interface name).

6.Highlight APPLY and press Enter to make the change current.

7.To modify an entry in the table, toggle the Action field to Modify, enter the changes, highlight APPLY, and press Enter.

8.Use Save Changes on the Main Menu to enter the table into NV-RAM.

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 a 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.

1. From the Main Menu, select Switch Utilities DNS Relay and press Enter.
