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” or “ip address ip-address/prefix-length,” where
“ip-address” is the switch IP address, “netmask” is the network mask for the network, and
“prefix-length” indicates how many contiguous bits (from the left) of the address comprise the
network portion of the address. 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>.
Console(config)#interface vlan 1
Console(config-if)#ip address 192.168.1.5 255.255.255.0
Console(config-if)#exit
Console(config)#ip default-gateway 192.168.1.254
Assigning an IPv6 Address
This section describes how to configure a “link local” address for connectivity within the local
subnet only, and also how to configure a “global unicast” address, including a network prefix for
use on a multi-segment network and the host portion of the address.
An IPv6 prefix or address must be formatted according to RFC 2373 “IPv6 Addressing
Architecture,” using 8 colon-separated 16-bit hexadecimal values. One double colon may be used
to indicate the appropriate number of zeros required to fill the undefined fields. For detailed
information on the other ways to assign IPv6 addresses, see
“Setting the Switch’s IP Address (IP
Link Local Address — All link-local addresses must be configured with a prefix in the range of
FE80~FEBF. Remember that this address type makes the switch accessible over IPv6 for all
devices attached to the same local subnet only. Also, if the switch detects that the address you
configured conflicts with that in use by another device on the subnet, it will stop using the address
in question, and automatically generate a link local address that does not conflict with any other
devices on the local subnet.
To configure an IPv6 link local address for 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>.
