Hello,

GigabitEthernet0/0/5 is up, line protocol is up 
  Hardware is 6XGE-BUILT-IN, address is f44e.0588.2d05 (bia f44e.0588.2d05)
  MTU 9216 bytes, BW 1000000 Kbit/sec, DLY 10 usec, 
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation 802.1Q Virtual LAN, Vlan ID  1.

looks like Your VLAN IDs do not match. That would explain all Your troubles.

Please double-check, make them the same, then re-test and report back.
