Router – LAN Settings
6 NN40011-042 Issue 1.2 BCM50 Rls 6.0
Note: It is possible to configure the DHCP service on the main module
instead of via the router itself. DHCP must be disabled on the router to be
able configure DHCP on the main module. Refer to the DHCP Guide for more
information.
DHCP & BCM50 VLANs
The BCM main unit supports VLAN configuration, useful for segregating IP
phone network traffic from regular data traffic for example. Each configured
VLAN can have its own DHCP range assigned.
If VLAN configuration is required for the network using the BCM, then the
BCM should be configured for this and the BCM should be used as the DHCP
server, as the router card does not support VLAN configuration. Refer to the
VLANs and DHCP Guides for information on how to perform this
configuration.
Static DHCP
If certain PCs/devices on the network (e.g. a FTP Server) require a specific IP
address, this can be defined in the Static DHCP section.
IP Alias
IP Alias allows you to partition a physical network into different logical
networks over the same Ethernet interface. The BCM50 Integrated Router
supports three logical LAN interfaces via its single physical Ethernet interface
with the BCM50 Integrated Router itself as the gateway for each LAN network.
IP Alias can be used to create separate networks that are physically
connected to the same LAN interface. For example, two departments can be
logically separated but connected by the same physical infrastructure. The
diagram below describes a possible usage of IP Alias.
