[AusNOG] Cisco ASR 1k series throughput licensing

[Tony Wicks]

On the “X” series routers the licencing is not honour system it is enforced (In+out, I remember seeing a document on this but can’t for the life of me find it, but it’s basically half duplex) for traffic passing through the ESP. All other licences (broadband user licence etc) are honesty system. I don’t know if the non-X series actually inforce their ESP 5/10/20/40/100 capacity but its fair to say they will be running out of puff if you exceed that amount anyway. These are great boxes if you need CPU type functions like NAT or L2TP as they don’t need services cards to do this sort of function (like a Juniper MX or ALU 7750 does) but don’t try and use them to switch traffic or you will just waste money very quickly. I use them for CGNAT and BNG functions and they are great. For General Routing and switching Juniper MX and EX are my personal choice.

ASR1002 ESP10 –

cr1-lab#show platform hardware throughput level                                               

% Error: This show command is not available on this device type

ASR1006 ESP40 -

r1-w#show platform hardware throughput level

% Error: This show command is only available on  Ultra, ASR1001, ASR1001x and ASR1002.

 

It seems the non-X don’t support the throughput command so I would assume there is no enforcement just a CPU performance capability limit.

 

Here’s a useful PowerPoint on the ASR from a few years ago. I’ve always assumed the 1002-x is an ESP-40 licence locked, and the 1001-x is an ESP-20, could well be completely wrong on that though.

The value of "orig_max" below is the aggregate software shaper for all interfaces.

 

This is taken from an ASR1002:

and on a CSR1000v with no bandwidth license (100kbps):

Anyone? I thought there'd be a heap of people here on list with ASR's....

Hey Noggers,

 

Can any Cisco "gurus" help me out here. The Cisco ASR1K series has throughput licensing (yes I know it's honour-based). I have a couple of questions regarding this:

 

1. How is the throughput measured? Is just the input or output rate on any of the interfaces?

 

2. If throughput reaches your licensed level what happens? Does it shape your traffic to the licensed rate regardless that there's heaps of other resources like CPU and memory?

 

For example the ASR1001 can be licensed only up 5Gbps but can take a 10Gbps interface. What happens after you reach the maximum licensed throughput of 5Gbps? Will it shape all the traffic on the 10Gbps interface to 5Gbps?
