Enabling SNMP Management Access
– 44 –
Address for Multi-segment Network — To generate an IPv6 address that can be
used in a network containing more than one subnet, the switch can be configured
to automatically generate a unique host address based on the local subnet address
prefix received in router advertisement messages. (DHCP for IPv6 can also be used
to obtain a unique IPv6 host address.)
To dynamically generate an IPv6 host 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 autoconfig” and press <Enter>.
3. Type “ipv6 enable” and press <Enter> to enable IPv6 on an interface that has
not been configured with an explicit IPv6 address.
Console(config)#interface vlan 1
Console(config-if)#ipv6 address autoconfig
Console(config-if)#ipv6 enable
Console(config-if)#end
Console#show ipv6 interface
VLAN 1 is up
IPv6 is enabled.

Enabling SNMP Management Access
The switch can be configured to accept management commands from Simple
Network Management Protocol (SNMP) applications. You can configure the switch
to respond to SNMP requests or generate SNMP traps.
When SNMP management stations send requests to the switch (either to return
information or to set a parameter), the switch provides the requested data or sets
the specified parameter. The switch can also be configured to send information to
SNMP managers (without being requested by the managers) through trap
messages, which inform the manager that certain events have occurred.
