u
Before any network interfaces are configured on the router, 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.
u
An IP address must be assigned to this device to gain management
access over the network or to connect the router 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.
u
An interface can have only one primary IP address, but can have many
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.
u
If
bootp
or
dhcp
options are selected, the system will immediately
start broadcasting service requests for all VLANs configured to obtain
address assignments through BOOTP or DHCP. IP is enabled but will not
function until a BOOTP or DHCP reply has been received. Requests are
broadcast periodically by the router in an effort to learn its IP address.
(BOOTP and DHCP values can include the IP address, default gateway,
and subnet mask). If the DHCP/BOOTP server is slow to respond, you
may need to use the
command to re-start
broadcasting service requests, or reboot the router.
N
OTE
:
Each VLAN group can be assigned its own IP interface address.
Therefore, if routing is enabled, you can manage the router via any of
these IP addresses.
E
XAMPLE
In the following example, the device is assigned an address in VLAN 1.
Console(config)#interface vlan 1
Console(config-if)#ip address 192.168.1.5 255.255.255.0
Console(config-if)#
