VS-S720-10G port channel error disable(not vss mode)

[tatsun]

hi

i have 2 x c6509e, each equiped with 1 x VS-S720-10G(with 2 x 10g port), i need to confiure portchannel with both 10g port between this two c6509e, and need to use standalone mode only(not VSS), however i found error disable from one side of switch after enabled the portchannel from 10g port,

i checked all fiber cable work fine, if not use portchannel configure, i can bring up both 10g port those switches,

here's the port channel configure(identical from both c6509e):

interface Port-channel1

switchport trunk encapsulation isl

switchport mode trunk

interface TenGigabitEthernet5/4
