LAN (10/100BaseT) commands
The 5100/6100 VDR supports one auto-sensing 10/100BaseT Ethernet port for LAN
connectivity. You will need to set the IP address and subnet mask to initiate LAN services. The
Ethernet port has a manufacturer preset IP address of 192.168.0.254 with a subnet mask of
255.255.255.0.
To configure the Ethernet port, you must employ one of two options:
•
To configure the Ethernet port, you must employ one of two options:
•
Use the set ip submenu to set a static IP address and the subnet mask IP address. To do this,
the DHCP mode must be set to off.
the DHCP mode must be set to off.
•
Use the set ip dhcp mode command to configure the VDR as a DHCP Client where the IP
address is assigned dynamically. The 5100/6100 VDR Ethernet port can operate as a DHCP
server.
address is assigned dynamically. The 5100/6100 VDR Ethernet port can operate as a DHCP
server.
Note. The Ethernet LAN port is not configurable for autonegotiation on/off. You
should disable autonegotiation on all downlink devices. When the remote end
operates in “forced” mode, the Ethernet port falls back to half-duplex mode, which
causes the port to operate incorrectly.
The 5100/6100 VDR provides a multi-homing feature on the Ethernet interface. There can be up
to three multi-homed addresses on the Ethernet, where each address can be either “Primary” or
“Secondary.”
Note. When upgrading software from a release that does not support the Ethernet
multi-homing feature to one that does, any Ethernet address presently configured will
default to a “primary” subnet. This means that traffic to or from the configured
Ethernet subnet will not be NAT-ed. Operators should modify this parameter as
necessary.
Note. A DHCP server can only serve DHCP clients on one of the up to three subnets
configurable on the Ethernet interface. The subnet selected for DHCP configuration
could be primary or secondary.
You can set an IP address for multinetting by issuing the set ip lan command and specifying the
address as either primary or secondary.
The distinction between primary and secondary is only in whether or not you want NAT traffic to
The distinction between primary and secondary is only in whether or not you want NAT traffic to
or from that network address. Traffic to or from a “primary” subnet is not NAT-ed while traffic
to or from a “secondary” subnet is NAT-ed.
Primary addresses are not mandatory if all the subnets on the Ethernet have to be NAT-ed, and
Primary addresses are not mandatory if all the subnets on the Ethernet have to be NAT-ed, and
likewise, it is not mandatory to have a “secondary” subnet is all traffic has to be not NAT-ed.
