| Initial Switch Configuration
Basic Configuration
– 47 –
◆ Auto IP — The switch randomly selects an IPv4 link-local address from the
range 169.254.0.1 – 169.254.255.254. Before starting to use it, the switch tests
to see if the address is already in use.
◆ Dynamic — The switch can send IPv4 configuration requests to BOOTP or
DHCP address allocation servers on the network, or can automatically generate
a unique IPv6 host address based on the local subnet address prefix received in
router advertisement messages. An IPv6 link local address for use in a local
network can also be dynamically generated as described in “Obtaining an IPv6
Address” on page 52.
The current software does not support DHCP for IPv6, so an IPv6 global unicast
address for use in a network containing more than one subnet can only be
manually configured as described in “Assigning an IPv6 Address” on page 48.
Manual Configuration
You can manually assign an IP address to the switch. You may also need to specify a
default gateway that resides between this device and management stations that
exist on another network segment. Valid IPv4 addresses consist of four decimal
numbers, 0 to 255, separated by periods. Anything outside this format will not be
accepted by the CLI program.
Note:
The IPv4 address for this switch is obtained via DHCP by default.
Assigning an IPv4 Address
Before you can assign an IP address to the switch, you must obtain the following
information from your network administrator:
◆ IP address for the switch
◆ Network mask for this network
◆ Default gateway for the network
To assign an IPv4 address to the switch, complete the following steps
1. From the Global Configuration mode prompt, type “interface vlan 1” to access
the interface-configuration mode. Press <Enter>.
2. Type “ip address ip-address netmask,” where “ip-address” is the switch IP
address and “netmask” is the network mask for the network. Press <Enter>.
3. Type “exit” to return to the global configuration mode prompt. Press <Enter>.
4. To set the IP address of the default gateway for the network to which the switch
belongs, type “ip default-gateway gateway,” where “gateway” is the IP address
of the default gateway. Press <Enter>.
