When I connected 3560 and 3560 with ipv6, it can ping, but it failed when I connect 3560 and 2960. Why?

Today I config the same configuration on both real 3560 and 2960. And they can't ping mutually.
Catalyst3560:
interface GigabitEthernet0/1
switchport access vlan 21
interface Vlan21
ip address 172.16.0.1 255.255.255.248
电脑172.16.0.5/29,可以ping通。
interface Vlan8
no ip address
ipv6 address 2001::1/64
ipv6 enable
interface GigabitEthernet0/2
switchport access vlan 8
电脑设置2001::2/64,可以ping通。可以telnet 2001::1
Catalyst2960:同AP交换机信息。
interface GigabitEthernet1/0/1
switchport access vlan 8
interface Vlan8
ip address 172.16.0.3 255.255.255.248
interface GigabitEthernet1/0/2
switchport access vlan 5
interface Vlan5
no ip address
ipv6 address 2001::3/64
ipv6 enable
电脑设置2001::2/64,可以ping通,可以telnet 2001::3

Today I config the same configuration on both real 3560 and 2960. And they can't ping mutually. - you mean to say after replacing the node with 2960 with 3560 the issue still the same ?
can you post show run from all device again -to cross check

Yes, on the physical switch both 2960 and 3560. But can't ping mutually.
Thanks. I will try.
