Configuring the Switch for Remote Management
– 75 –
To generate an IPv6 global unicast 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>.
2. From the interface prompt, type “ipv6 address ipv6-address” or “ipv6 address
ipv6-address/prefix-length,” where “prefix-length” indicates the address bits
used to form the network portion of the address. (The network address starts
from the left of the prefix and should encompass some of the ipv6-address
bits.) The remaining bits are assigned to the host interface. Press <Enter>.
3. Type “exit” to return to the global configuration mode prompt. Press <Enter>.
4. To set the IP address of the IPv6 default gateway for the network to which the
switch belongs, type “ipv6 default-gateway gateway,” where “gateway” is the
IPv6 address of the default gateway. Press <Enter>.
Console(config)#interface vlan 1
Console(config-if)#ipv6 address 2001:DB8:2222:7272::/64
Console(config-if)#exit
Console(config)#ipv6 default-gateway 2001:DB8:2222:7272::254
Console(config)end
