2921 to 6500 trunk.. can't ping

I know I'm forgetting something stupid..

Have the following configuration:

router A:

int g0/0.79

description to switch A g1/5

encap do1q 79

ip address 10.27.79.24 255.255.255.0

no shut

switch A

:

int vlan 79

nterface Vlan79

description SWITCH MANAGEMENT VLAN

ip address 10.27.79.4 255.255.255

int g1/5

desc to router A g0/0

switchport

switchport trunk encap dot1q

switchport trunk allowed vlan all

All the interfacess are up, but I can't ping.. what did I forget????

Is the subnet mask on the 6500 for vlan 79 really 255.255.255.255 ?

If so change it to 255.255.255.0

Do you need to set the interface on the switch to be in trunk mode?

int g1/5

switchport mode trunk
