vss 1440 Link aggregation in the port-channel

We are setting up a vss 1440 with 2 6509.  I have 2 supervisor blades per chassis.  I have 4 tengig ports on each switch in each port channel.  we followed the configuration guide from CISCO.  In a SH IP INT BR we only see one port on each switch in the port-channel as up.  We want all ports up, after doing some research on the web I am still stuck.  Does anyone have any ideas?

Hi, Thanks, we got it figured



Thanks, we got it figured out. When we ordered the chassis they back ordered one sup720.  When we got it we did not notice that it was not a 10G-3CXL, it was a 10G-3C.  On the other chassis with the 2 correct blades we updated the IOS to the newest version on the active blade but not the standby.  For the most part it is up and running on 3 sup blades.
