| Initial Switch Configuration
Configuring the Switch for Remote Management
ā 75 ā
To generate an IPv6 global unicast address for the switch, complete the following
steps:
1. From the global configuration mode prompt, type āinterface vlan 1ā to access
the interface-configuration mode. Press <Enter>.
2. From the interface prompt, type āipv6 address ipv6-addressā or āipv6 address
ipv6-address/prefix-length,ā where āprefix-lengthā 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 āexitā 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 āipv6 default-gateway gateway,ā where āgatewayā is the
IPv6 address of the default gateway. Press <Enter>.
