8.7 DHCP Relay Agent
Upgrading and changing the structure of Ethernet networks usually causes a lot of administrative
effort. Conguration of security and addressing procedures has to be redone every time a device
is replaced. Replacing or moving network devices often causes a lot of trouble, because some
network mechanisms such as dynamic IP address assignment are MAC based.
DHCP Option 82 provides a mechanism for generating IP addresses based on the location of the
client device in the network. A client device can be any device attached to the switch or the switch
itself.

Function Description
DHCP Relay Agent
Status
Enables or disables the DHCP Relay Agent on the switch. To use
Option 82 this option must set to enable.
Range of value: Enable / Disable / Enable RFC conform
Default value: Disable
DHCP Option 82 Select whether to disable or enable Option 82 on the switch.
Range of value: Enable / Disable
Default value: Disable
Circuit-ID Denes the Circuit-ID to identify the location of the end device in the
network.
Range of value: VLAN ID / Port ID
HARTING Ha-VIS mCon 3000 switches can be operated in the following PTP modes:
• Boundary Clock: The device can either be a master or a slave. As a slave, the switch
synchronizes the clock with another master. The master itself provides its time to the other
slaves.
• End to End transparent clock: The switch forwards the PTP messages which are exchanged
between the masters and the slaves and adds the processing time in the switch itself to the
correction eld in the message. The slaves can use this to determine the correct time.
• Peer to peer transparent clock: The switch forwards the PTP messages which are exchanged
between the masters and the slaves and adds the processing time in the switch itself and the
link delay to the correction eld in the message. The slaves can use this to determine the
correct time.
Figure 8-12 PTP Settings section
The following settings can be made in this menu:
Function Description
Enable PTP Switch PTP on or off
PTP Mode Selection of the operating mode
Range of value: Boundary / Transparent
PTP Priority 1 Enter the priority 1. Available only in boundary mode
Range of value: 0...255
Default value: 0
PTP Priority 2 Enter the priority 2. Available only in boundary mode
Range of value: 0...255
Default value: 0
Two-Step Mode Dene whether the switch device should send only Sync-Messages
or whether it should send Sync Messages and FollowUp Messages,
which means Two-Step-Clock. (Boundary mode only)
Two-Step Transparent-
Clock
Dene whether the switch device should send only Sync-Messages
or whether it should send Sync Messages and FollowUp Messages,
which means Two-Step-Clock. If the device receives Sync Messages
from a one Step Device, it will generate the FollowUp Messages.
(Transparent mode only)
Delay-Mechanism
Transparent-Clock
Specify the delay mechanism of the transparent clock. (Transparent
mode only)
Range of value: End to End / Peer to Peer
