And here is one more, guess I won't be using it at all:

This is mentioned under the MPLS config guide - it is not mentioned at all 
under the Netflow configuration guide.

SDM templates are supported only by the Metro Aggregation Services license. Use 
the help option of the sdm prefer command to display the supported SDM 
templates.

Subject: [c-nsp] netflow restrictions on ASR920

o    Ok I am about to configure this on an ASR-920-4SZ-A

I am seeing some alarming restrictions in the configuration guide:

Restrictions for Netflow Monitoring for ASR 920 Series Routers
*         Netflow monitoring supports only the 7 keys-Source IP, Destination 
IP, Layer 3 protocol type, TOS, source port, destination port and input logical 
interface to identify or classify the flow for both IPv4 and IPv6 unicast 
traffic. All other keys are notsupported.
*         MPLS and BGP-based netflow is not supported.
*         Non-key fields supported are packets and bytes (collect counter 
packets and collect counter bytes)
*         Only routed ports (IP Ethernet, BDI) and EFP are supported.
*         EFP flow monitoring can be configured only after configuring 
bridge-domain on the EFP service instance.
*         Flow monitoring of multicast traffic is not supported.
*         Maximum of 16K flows can only be learnt due to FPGA limitations. 
Though, Netflow supports 16K entries, flows monitored are lower due to hash 
collisions.
*         FPGA monitor only 1Gbps traffic rate (with minimum frame size of 100 
byte). The accounting is accurate only when the overall traffic monitored is 
within 1Gbps.
*         At interface level, MVPN/MLDP/SPAN/PBR feature cannot be enabled on 
the same interface with Netflow configuration.
*         Permanent and aggregate flow caches are not supported due to FPGA 
limitations.
Configuration of caches entries number is not supported.
*         SADT/BFD feature cannot co-exist with Netflow configurations for the 
following routers:
o    ASR-920-12CZ-A
o    ASR-920-12CZ-D
o    ASR-920-4SZ-A
o    ASR-920-4SZ-D
o    ASR-920-12SZ-IM
o    ASR-920-16CZ-IM

  *


So If I am reading this correctly - my 10gig link will not have correct 
information when the traffic goes over 1 gig in untilization?
Is this due to the ASIC FPGA logic on this hardware?

I cannot use PBR on this interface
And I cannot enable BFD?

Am I missing something or this is a bit of an afterthought for this router?
Any help/experience greatly appreciated

Nick
