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. Nick -----Original Message----- From: cisco-nsp [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Nick Cutting Sent: Wednesday, January 11, 2017 10:14 PM To: cisco-nsp (cisco-nsp@puck.nether.net<mailto:cisco-nsp@puck.nether.net>) <cisco-nsp@puck.nether.net<mailto:cisco-nsp@puck.nether.net>> 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 _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net<mailto:cisco-nsp@puck.nether.net> https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net<mailto:cisco-nsp@puck.nether.net> https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
