Cabletron Systems CSX1000, CSX1200 manual Configuring a Dhcp Relay Agent Using Cfgedit

USER’S GUIDE

FORWARD	IP Src 255.255.255.255, 201.55.89.100	Allows specific host to access the Net-
	IP Dst: 255.255.255.255, 128.131.25.11	server.
	IP Prot: ANY
FORWARD	All other packet types	If no match, let filter execution contin-
		ue with the existing input filter.

Once the offsite maintenance is completed, the Exception filter would be disabled. Configuration control over the Exception filter is available both through CFGEDIT and Manage Mode (with Manage Mode being the most practical method due to its dynamic nature).

DHCP RELAY AGENT

CONFIGURING A DHCP RELAY AGENT

USING CFGEDIT

1.Select DHCP Configuration from the IP Routing menu.

2.Press 1 to begin the DHCP configuration.

3.Follow the onscreen instructions to enable the DHCP/BOOTP relay agent. Once the agent has been enabled, the following menu will be displayed:

DHCP/BOOTP Relay Agent Menu:

1)DHCP/BOOTP Relay Agent (Enable/Disable)

2)Relay Destination IP Addresses

3)Hop Count Threshold

Select function from above or <RET> for previous menu:

4.Press 2 to configure relay destination IP addresses.

a.Press 1 to add an address.

b.Enter the relay destination IP address in dotted decimal notation. If you want to broadcast out to find the DHCP server, enter 255.255.255.255 for the IP address.

c.If you have entered 255.255.255.255 for the IP address, you will need to select the network interface to which DHCP/BOOTP request messages should be relayed.

5.Press 3 to configure the hop count threshold. Enter the threshold value, or press return to accept the default. Be careful when configuring the hop count. Make sure you have configured the threshold value high enough; messages with a hop field greater than this value will be discarded.
