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
