MX104 limitation

Hi everyone,

I need a bit of your knowledge.
I have a MX104 as PE router with 4 LAGs.
One LAG facing to P router on FPC2 (fixed ports). The other LAGs distributed in FPC0 and FPC1.
The problem is that traffic is being limited when reach 28G out/ 4G in (31Gbps total).
I changed one interface (10G) of the LAG (to P router) to FPC1 and the traffic has grown a little more.

 

Where is the limitation? In the MQ chip?
How much traffic will the router support on FPC2?

Where could I get a graphic of its internal architecture?
Does a MX80 have the same behavior?

 

Thanks in advance,

 

Javier.

Re: MX104 limitation

Hi Javier,

 

Initial thought, have you enabled tunnel services and allocated 10G bandwidth for this? This will be retracted from the FPC capacity so this has to be taken into consideration when allocating bandwidth.

 

look for something like;

 

chassis {
     fpc 2 {
         pic 0 {
             tunnel-services {
                bandwidth 1g;
}
}
}
}

Regarding the limitation/architecture questions I would very much recommend the book "Juniper MX Series 2nd edition" which covers all your questions and then some :-)

Re: MX104 limitation

Hi Jonas,

 

Thanks for your suggestion.

In  this case it only has a tunnel service of 1g at fpc0.

Yes, i have taken a look at the MX Juniper book, but doesn't indicate the bandwidth capabilities of fpc2 in mx104 and fpc0 in mx80.  At MX104 fpc2 (fixed ports) can't overcome 31Gbps (in + out) with 6Mpps. The graph shows a straight line as if it were being limited .I have moved some interfaces from LAG to fpc1 and fpc0 and the traffic has incresed.

Where do you think I can keep looking for the problem?

 

Thank you,

Regards,

 

Javier.

Re: MX104 limitation

Hi, 
 
I deactivated the inline jflow and the traffic has increased.
Now I ask, what is the real forwarding capacity of this box? 40G in + 40G out? (now it didn't reach 40G in total) 
 
Thank you,
 
Javier.

Re: MX104 limitation

Hi Folks,

Please find the datasheet for MX960, MX480, MX240, MX104 and MX80 3D Universal Edge Routers.

Re: MX104 limitation

Hi,

Thanks, I had already seen the datasheet. Says that the capacity is 80Gbps but when i enable inline jflow on some interfaces the capacity in our MX104 didn't reach 40Gbps (total = 34Gbps inbound / 4 Gbps outbound)
If it is helpful, the sampling that I do is on 35 Gbps of traffic (input only) with rate of 10000.

Is there something I'm not considering of the MX104 or MX80?

 

Thanks,

 

Javier.
