The transmitter behavior configuration should be the same on both the local and remote ports.
DHCP Relay IP Address
The DHCP Relay feature allows DHCP clients on the local port subnet to access a DHCP server that is
on a different subnet. The DHCP relay feature is applicable in Layer 3 IP networks.
Enable the DHCP Relay feature only on ETEPs that have DHCP clients on the local port that require
access to a DHCP server that is on a different subnet from the local clients (see Figure 106). This feature
is not needed when DHCP servers or relay agents are on the same local network with the DHCP clients,
nor is it needed on the ETEP at the remote site where the DHCP server is located.
Figure 106 DCHP Relay allows local clients to access a DHCP server on a remote subnet
Local and remote port IP addresses are required for proper DHCP Relay Agent behavior. In order to use
local and remote port IP addresses, the ETEP must be operating in non-transparent mode.
To use the DHCP Relay feature, configure the following items on the Interfaces tab:
1 Disable transparent mode.
2 Assign local and remote port IP addresses to the ETEP.
3In the DHCP Relay IP Address field, enter the IP address of the DHCP server.

Setting Description
Follow receiver The transmitter follows the behavior of the receiver. If loss of signal is detected
on the remote port, then the transmitter on the local port is disabled. Similarly, if
loss of signal is detected on the local port, the ETEP disables the transmitter on
the remote port. When the lost signal is restored, the correlating transmitter is
enabled.
Always The transmitter is always on regardless of whether a signal is received.
