Configuring IPv6 Host Functions
Configuration Examples for IPv6 Host Functions
Switch# show ipv6 interface gigabitethernetfastethernet1/0/11
GigabitEthernetFastEthernet1/0/11 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::20B:46FF:FE2F:D940
Global unicast address(es):
2001:0DB8:c18:1:20B:46FF:FE2F:D940, subnet is 2001:0DB8:c18:1::/64 [EUI]
Joined group address(es):
FF02::1
FF02::2
FF02::1:FF2F:D940
MTU is 1500 bytes
ICMP error messages limited to one every 100 milliseconds
ICMP redirects are enabled
ND DAD is enabled, number of DAD attempts: 1
ND reachable time is 30000 milliseconds
ND advertised reachable time is 0 milliseconds
ND advertised retransmit interval is 0 milliseconds
ND router advertisements are sent every 200 seconds
ND router advertisements live for 1800 seconds
Hosts use stateless autoconfig for addresses.
Configuring DRP: Example
This example shows how to configure a DRP of high for the router on an interface.
Switch# configure terminal
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# ipv6 nd router-preference high
Switch(config-if)# end
Configuring an IPv6 ICMP Error Message Interval
This example shows how to configure an IPv6 ICMP error message interval of 50 milliseconds and a bucket size of 20
tokens.
Switch(config)# ipv6 icmp error-interval 50 20
Displaying Show Command Output: Examples
This is an example of the output from the show ipv6 interface privileged EXEC command:
Switch# show ipv6 interface
Vlan1 is up, line protocol is up
