IP Routing
19-6
19
• Before you configure any network interfaces on this router, you should first create
a VLAN for each unique user group, or for each network application and its
associated users. Then assign the ports associated with each of these VLANs.
• An IP address must be assigned to gain management access over the network or
to connect the switch to existing IP subnets. A specific IP address can be manually
configured, or the router can be directed to obtain an address from a BOOTP or
DHCP server. Valid IP addresses consist of four numbers, 0 to 255, separated by
periods. Anything other than this format is not be accepted by the configuration
program.
Command Attributes
•
VLAN
– ID of configured VLAN (1-4093).
•
IP Address Mode
– Specifies whether the IP address for this interface is statically
assigned, or obtained from a network address server. (Options: Static, DHCP -
Dynamic Host Configuration Protocol, BOOTP - Boot Protocol; Default: Static)
- If Static address type is selected, then you must also specify whether the IP
address is the primary IP address on the VLAN or a secondary IP address. An
interface can have only one primary IP address, but can have multiple
secondary IP addresses. In other words, you will need to specify secondary
addresses if more than one IP subnet can accessed via this interface.
- If DHCP/BOOTP is enabled, the system will immediately start broadcasting
service requests. IP is enabled but does not function until a reply has been
received from the address server. Requests will be broadcast periodically by the
router for an IP address. (DHCP/BOOTP values can include the IP address,
default gateway, and subnet mask.)
•
IP Address
– Address of the VLAN interface. Valid IP addresses consist of four
numbers, 0 to 255, separated by periods.
•
Subnet Mask
– This mask identifies the network portion of the address used for
routing to specific subnets.
•
Secondary
– If Static address type is selected, the IP address can be the primary
IP address on the VLAN or a secondary IP address. An interface can have only one
primary IP address, but can have multiple secondary IP addresses. In other words,
secondary addresses need to be specified if more than one IP subnet can be
accessed through this interface.
Note that a secondary address cannot be configured prior to setting the primary IP
address, and the primary address cannot be removed if a secondary address is still
present. Also, if any router in a network segment uses a secondary address, all
other routers in that segment must also use a secondary address from the same
network or subnet address space.
