Hello all,
When doing some tests using the ‘loopback line’ on a 10GbE interface in an ASR9000, we noticed that we don't have output rate, although the test device receive all the generated traffic back. The interface configuration is rather simple:
RP/0/RSP0/CPU0:Pessoa#sh run int tenGigE 0/0/0/2
Thu Feb 16 11:59:14.431 WET
interface TenGigE0/0/0/2
description Testes 10 GbE RFS
mtu 9192
loopback line
carrier-delay up 5000 down 0
load-interval 30
dampening
When checking the input and output rate:
RP/0/RSP0/CPU0:Pessoa#
RP/0/RSP0/CPU0:Pessoa#sh int tenGigE 0/0/0/2 | i rate
Thu Feb 16 12:01:40.476 WET
30 second input rate 7918041000 bits/sec, 1448815 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
RP/0/RSP0/CPU0:Pessoa#
RP/0/RSP0/CPU0:Pessoa#sh int tenGigE 0/0/0/2 | i rate
Thu Feb 16 12:02:05.307 WET
30 second input rate 9166768000 bits/sec, 1677058 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
RP/0/RSP0/CPU0:Pessoa#
RP/0/RSP0/CPU0:Pessoa#
RP/0/RSP0/CPU0:Pessoa#sh int tenGigE 0/0/0/2 | i rate
Thu Feb 16 12:02:07.321 WET
30 second input rate 9212136000 bits/sec, 1685490 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
RP/0/RSP0/CPU0:Pessoa#
RP/0/RSP0/CPU0:Pessoa#
The same tests were done using a 1GbE interface and every think was OK, with output rate ~= input rate.
Any ideia? I've done some research in bug toolkit but didn't find any bug related to this...
By the way, IOS-XR version is 4.0.1.
Thanks & Regards,
Pedro
