Network switchport trunk settings?

Hi All,

I have a pair of 8024 switches in a stack, I have on the first switch
interface Te1/0/1
description "Blade1"
switchport mode trunk
switchport trunk allowed vlan 11,32-33,98,111,170,172
exit

but on the second switch I only have:

interface Te2/0/1
switchport mode trunk
exit

Should the second switch have the same switchport setting as the first switch or is it set up incorrectly for a stack?  The second switch appears to pas traffic into the attached Virtual network, how?

Thanks

Eric
