Do you mean that I should configure the router like above ?
f8/0 is for only inbound and f8/1 is for only outbound ?
(I'm using only f8/0, f8/1 is in shutdown.)
I'm sorry to you that I don't know what you mean exactly.

I'm using only f8/0 with full-duplex.
I think that 'transmit-interface' is not applicable in this configuration.

I have another router with VIP2-50 with PA-FE-TX.
And the "rxhi" of the FastEthernet is 90.
I'll borrow a VIP-2/40 with PA-FE-TX if that increase the "rxhi".
The inbound traffic at the FastEthernet is at most 23Mbps.
The outbound traffic at the FastEthernet is at most 6Mbps.
The problem is happening because the inbound traffic of the FastEthernet
can not be switched to other interfaces. The other inferfaces are
requesting a lot of traffic and they can not accept that traffic
at their interfaces because their physical bandwidth is smaller
than the inbound traffic at the FastEthernet.
