Can not enable ipv6 unicasting

[Eakapong Gomonsing]

I have cisco catalyst Model WS-C3560X-48, SW Version 15.0(1)SE2, SW Image C3560E-UNIVERSALK9-M

Switch Ports Model              SW Version            SW Image                

------ ----- -----              ----------            ----------              

*    1 54    WS-C3560X-48       15.0(1)SE2            C3560E-UNIVERSALK9-M    

I want to enable ipv6 but I can't

Switch(config)#ip?

ip  ipc 

I search on cisco Feature Navigator it tell that this image can support ipv6.

Have you enabled 'ipv6 unicast-routing' enabled in the global config mode?

What is the sdm template you are using?

and report it back here if it fails.

Thank you for your reply and I can not open the link because of Forbidden.

I type the command ipv6 unicasting but it can not.

Remove the word "partner" from the URL, and you should have access:

Wonderful, after i configure command

Switch(config)#sdm prefer dual-ipv4-and-ipv6 default

i can use IPv6 features.

Thank, Andre.

Why we need to configure this command for the switch?

Any special reason?
