100Gb Interface MTU

Fredy caceres cabrera · ‎07-07-2015

Some one could help me, I want to know MTU value for the interface of the ASR SR 100Gb, because when traffic goes through interface a problem of performance (slow traffic) appears. I think it's a MTU problem because 100Gb inteface is a high-density interface and MTU is crucial in these cases.

Regards.

Hi

Max configurable MTU on the ASR9K is 9216. This will give you 9220 as max allowed frame size. If you haven't configured anything in the CLI the default MTU is 1514.

Regards Peter

Fredy caceres cabrera · ‎07-08-2015

Hi Peter,

I try MTU 9216 but traffic still have a slow performance, when I do a rollback the traffic have a normal performance, that interface is a bundle, 4X10Gb.

Regards.

Peter L · ‎07-08-2015

Hi

Can you clarify "slow performance" a bit more?`Don't you get expected performance or what is wrong? Have you checked the 100gb interface in both ends for drops/errors?

/Peter

Fredy caceres cabrera · ‎07-13-2015

Hi Peter,

slow connection to internet, when a pass the traffic trought de 100Gb interface, I do not see any drop and error on the interface, but when I pass trough de 4x10Gb interface (Bundle interface) the connection to internet work perfect, That's why I think it is a problem concerning MTU

Hi Fredy,

your interface counters are clean, all your L1 stats are solid also, and you dont have any fragmentation issue as far as I can tell:

Input pkts 1024-1518 bytes = 4069777
Input pkts 1519-Max bytes = 0

I am suspecting that you are testing the circuit with too few flows.

As Sam hinted on these 2 cards have a FIA (fabric interface asic) that use VOQ's (virtual output queues) that are shaped at 13G and in some releases with a specific configuration setting can be set to 21G (or somewhere there).

A 100G interface is represented by 10 of those VOQ's, a single 10G interface is represented by 1 VOQ and ten 1G interfaces share a VOQ together also.

VOQ's are used to prevent head of line blocking and also provide for priority propagation (since each VOQ has 4 priority VQI's = virtual queuing instance).

yeah lots of TLA's (three letter acronyms) and if you like to read more on this check out this set of info.

To identify where the drops are coming from and propose the right mitigation check this:

show controller np counters [np] location [slot loc of LC]

run that twice to get some decent rate counters with a 1-5 second interval.

this will identify if we have to punt packets to the CPU, or whether we are losing something there.

the next thing to check is the:

show controller fabric fia stats location, this will help us identify the VOQ queue depth, and (tail) drops that happen in that asic.

I suspect you see voq depth building and tail drops which would identify the fact that your flow variety is not good enough.

you need minimally 10 10G flows (and preferably more flows) in order to take the power of this card.

Flows are loadbalanced over the available VOQ's. How the loadbalancing works is part of the deck set I ref'd above also.

The Tomahawk set of linecards can do single flow 100G.

To make sure, the 1x100 or 2x100 have no flaw or anything, but were bound by the technology available at the time to develop FIA's to support rates like this.

And also the fact that the PHY (optical piece) is connecting via multiple SGMII lanes to the MAC FPD (part of the NPU). In short you need flow variety :)

regards

xthuijs · ‎07-14-2015

yeah that helps,

you seem to be ABF (access list based forwarding) a lot of packets coming in on the interface back out of it again!? is that right?

may want to remove ABF for a second and see if it is forwarded the way you expect...

xander

Fredy caceres cabrera · ‎07-15-2015

Alexander,

I can not remove the ABF because the ASR has an ISM module and doing CGN using ABF.
I use ABF to divert traffic to the ISM.

Regards.

Aleksandar Vidakovic · ‎07-15-2015

Hi Fredy,

NP counters don't show any drops. There are also no drops on the fabric. The traffic rate on the HundredGigE0/7/0/0 is far less than 13Gbps, so the VQI shaper doesn't come into the picture here even if you had all the traffic calculated to the same hash value. Can you explain a more comprehensively what did you exactly mean by "slow traffic"? Why are you suspecting an issue with MTU (the controller counters don't show any frames received or sent with size above 1518 bytes)?

regards,

/Aleksandar

Fredy caceres cabrera · ‎07-15-2015

Hi Aleksandar,

Here the topology

Users who use the services of 3G, FTTH, GPON, feel slow Internet connection. do not load youtube videos, web pages open slowly.
When the traffic passing back through the interface Bundle 2x10Gb (no shutdown) everything works normally. So I thought it was something of MTU, but I think even that is not the problem.

Regards.

Fredy caceres cabrera · ‎09-07-2015

Hi all,

I want to tell you that I had solve the problem using a bundle interface then associated with the physical interface 100Gb in this way started to run smoothly.

It is strange to work this way, but it works.

:-D

Regards.

smilstea · ‎07-09-2015

Which 100GbE card are you using?

How many flows do you have?

The 1 and 2x100 cards on 9K are limited to around 13G per flow.

Thanks,

Sam

Fredy caceres cabrera · ‎07-13-2015

Hi smilstea,

The card is A9K-2x100GE-TR.

I don't understand about 13G per flow, sorry, could you explain me please?
