Chapter 3: Device Configuration
Operation under the Network DHCP selection allows users to temporarily wander outside of the
network infrastructure without losing connectivity.
The server may be configured by the operator to hand out temporary or static leases. The VMM must
associate and acquire an address from the network before establishing communications. Once a lease
has been granted, the address will be valid out of network coverage for the remainder of the lease or, if
a static lease was granted, until the next power cycle. If the lease expires or the user cycles power
while outside of network coverage, the user will again lose the ability to communicate with the
wireless network.
Additional Information about the Statically Provisioned Setting
When selecting the Statically Provisioned Bridge Addressing option from the Configuration web
page, the VMM device will use provisioned DHCP-like information to establish an IP address for use
in the wireless network. A DHCP server is not required on the core network because the addresses are
derived from the MAC address by default. It should be noted that a DHCP server can still exist on the
network to hand out addresses to other nodes using the Network DHCP option as long as the server's
address range does not conflict with addresses assigned to other devices using the Statically
Provisioned option.
The IP addresses and options used are also configurable per-device using the MOTOMESH
MeshManager application.
The Network Operator can choose to keep the provided (derived IP address) or assign a fixed IP
address and subnet mask. It is up to the Network Operator to ensure that the assigned address is
routable on the core network (if core network access is needed) and that it does not conflict with other
addresses in use. This is analogous to and carries the same caveats as plugging an Ethernet card into a
LAN and manually assigning an address to the card.
DHCP Server Section (External Device Provisioning)
Prior to attaching external devices to the VMM device, the resident DHCP server needs to be enabled.
The current VMM factory defaults automatically enable the DHCP server feature.
Table 3-4 Device Web Interface - DHCP Server Section (Configuration Tab)
Field Name Field Description Field Default
Value
Enabled The VMMs resident DHCP server is enabled when this
checkbox is selected. Use this feature when you need to
attach several devices to the VMMs Ethernet port via a hub or
similar device. The recommended limit is 50 attached
devices. Check box checked,
feature enabled
DHCP Range Start
This is the first IP address in a range of IP addresses that the
local DHCP server will allocate to any new clients connected
to the VMM (with the enabled DHCP server).
