catalyst 4500 won't create another trunk int

I've somehow been able to get gi2/2 to pass multiple vlan's over a trunk, but now can't seem to duplicate steps on gi2/3, here are the steps I'm trying:

Switch#show interfaces trunk

Port        Mode             Encapsulation  Status        Native vlan
Gi2/2       on               802.1q         trunking      1
Gi2/5       on               802.1q         trunking      1

Port        Vlans allowed on trunk
Gi2/2       90,98
Gi2/5       90,98

Port        Vlans allowed and active in management domain
Gi2/2       90,98
Gi2/5       90,98

Port        Vlans in spanning tree forwarding state and not pruned
Gi2/2       90,98
Gi2/5       90,98
config t Switch(config)#interface gi2/3 Switch(config-if)#shut Switch(config-if)#switchport mode trunk Switch(config-if)#switchport trunk encapsulation dot1q Switch(config-if)#switchport trunk allowed vlan 90,98 Switch(config-if)#no shut Switch(config-if)#end Switch# 02:19:15: %SYS-5-CONFIG_I: Configured from console by console Switch#show interfaces trunk Port Mode Encapsulation Status Native vlan Gi2/2 on 802.1q trunking 1 Gi2/5 on 802.1q trunking 1 Port Vlans allowed on trunk Gi2/2 90,98 Gi2/5 90,98 Port Vlans allowed and active in management domain Gi2/2 90,98 Gi2/5 90,98 Port Vlans in spanning tree forwarding state and not pruned Gi2/2 90,98 Gi2/5 90,98

For some reason gi2/3 doesn't show passing the two vlan's, just vlan 1:

Switch#show vlan b

VLAN Name                             Status    Ports
---- -------------------------------- --------- -
1    default                          active    Gi1/2, Gi2/3, Gi2/4,
...
90   vlan90                           active    
97   vlan97                           active    Gi2/1
98   vlan98                           active    
 

What am I missing?

I know you did a "no shut" but is the interface actually showing as up/up ("sh ip int br"). 

 

It has to be up to be seen in the "sh int trunk" output.
