[AusNOG] Cisco ASR 1k series throughput licensing

[Nathan Le Nevez]

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



This is taken from an ASR1002:



Router#show pla ha qfp a infra bqs qu ou def int g0/0/0 hier det | sec Shaper

    Index 1 (SID:0x260, Name: Shaper)

      Software Control Info:

        evfc_fc_id: 0xffff, fc_sid: 0x260

        max_qos   : 0                   , max_dflt: 2500000000



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

        orig_max  : 0                   ,      max: 100000

        max_qos   : 0                   , max_dflt: 100000

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?
