Configuring IP Information

IP Addressing

Cisco Small Business SFE/SGE Managed Switches Administration Guide 212

Add UDP Relay Page

The

Add UDP Relay Page

contains the following fields:

• Source IP Interface — Indicates the input IP interface that relays UDP packets.

If this field is 255.255.255.255, UDP packets from all interfaces are relayed. The

following address ranges are

- 0.0.0.0 to 0.255.255.255.

- 127.0.0.0 to 127.255.255.255.

• UDP Destination Port— Indicate the destination UDP port ID number of the

relayed UDP packets. The following table lists UDP Port allocations

• Destination Address— The IP interface that receives UDP packet relays. If this

field is 0.0.0.0, UDP packets are discarded. If this field is 255.255.255.255, UDP

packets are flooded to all IP interfaces.

STEP 3 Define the relevant fields.

STEP 4 Click Apply. The UDP Relay Settings are defined, and the device is updated.

Defining DHCP Relay (Layer 2)

The

DHCP Server Page

enables users to establish a DHCP configuration with

multiple DHCP servers to ensure redundancy.

The DHCP servers act as a DHCP relay if the parameter is not equal to 0.0.0.0.

DHCP requests are relayed only if their SEC field is greater or equal to the

threshold value. This allows local DHCP Servers to respond first.

The table on this page lists ports and LAGs on which DHCP relay has been

enabled.

To define the DHCP Relay configuration:
