I do not see this issue on a SXI5 box - see below.

You may want to try:

default interface Te13/1
default interface Te7/4

no inter port16
no inter port16a

interface Te13/1
channel-group 16 mode passive
interface Te7/4
channel-group 16 mode passive

- and then see what "show etherchannel summary" outputs...


==== example config

gv(config-if)#do show etherch summary
