We're in a bit of a problem right now, we have a MOD400-TR + MPA-2x100G and when we plug into the ASR9006-V2 or ASR9010-V2 chassis throw the following warning:
%FABRIC-FIA-1-RATE_LIMITER_ON : Set|fialc|0x1073000|Insufficient fabric capacity for card types in use - FIA egress rate limiter applied
And of course if i check the throughput on the MPA ports the RX is arounf 100G but the TX is around 39G.

NODE module 0/RSP0/CPU0 ASR9K Route Switch Processor with 440G/slot Fabric and 12GB
NODE module 0/1/CPU0 400G Modular Linecard, Packet Transport Optimized
MPA 0/1/0 : ASR 9000 2-port 100GE Modular Port Adapter
Could anyone guide me in how to solve this, i did the same exactly configuration for another customer not so long ago and was working fine (so 100G TX/100G RX).
First test (the one for the other customer that was working) was only with one RSP440 but this one i tested with one and two SUPs.
I forgot to mention in my first message that i was using a really basic L2 config (ports configured as l2transport and assigned to the same bridge domain).
Right now i have it working in basic L3 but would like to know why in the past it worked in L2 with only one supervisor.
There are quite a few variables here.
1st , with 1 RSP the fabric will be limited to 220G
2nd, we do not know the dest port, if its a 10G line card for example there is a limitation of VOQ size, which will only allow 13-18G per flow (from 100G LC to 10G LC)
3rd, we do not know the packet size, if it is small size packet for example there is a chance the NP is being overwhelmed and experiencing tail drops
let me know if you have any additional questions
I understand the fist point, last test was with 2 RSP.
2) Traffic flows from 1 port of the 2x100G to the other (just a required proof for the customer).
3) packet size is 9000 and mtu is configured as 9216 in both interfaces.
