The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

IPsec is not supported in Cisco IOS XE Fuji 16.7.1 release.
The ip cef accounting command is not supported on the router.
Erasing router configuration using write erase command does not work on standby mode.
Crash may be observed on the router when:
EoMPLS, CEM, ATM and IMA Pseudowire Redundancy (PW-redundancy) configurations exist while switchover and fail-back of the pseudowires are being triggered, and the show platform hardware pp active pw eompls command is executed.
Configuration sync does not happen on the Standby RSP when the active RSP has Cisco Software Licensing configured, and the standby RSP has Smart Licensing configured on the router. If the active RSP has Smart Licensing configured, the state of the standby RSP is undetermined. The state could be pending or authorized as the sync between the RSP modules is not performed.
Evaluation mode feature licenses may not be available to use after disabling, and enabling the smart licensing on the ASR 903 RSP2 module. A reload of the router is required.
Ingress counters are not incremented for packets of the below format on the RSP3 module for the 10 Gigabit Ethernet interfaces, 100 Gigabit Ethernet interfaces, and 40 Gigabit Ethernet interfaces:
Packet Format
MAC header---->Vlan header---->Length/Type
When these packets are received on the RSP3 module, the packets are not dropped, but the counters are not incremented.
ISSU is not supported between a Cisco IOS XE 3S Release and the Cisco IOS XE Fuji 16.7.1.
This is applicable only to Cisco ASR903 RSP2 module.
Traffic is dropped when packets of size 64 to 100 bytes are sent on 1G and 10G ports.
For 64-byte packets, traffic drop is seen at 70% and beyond of the line rate.
For 90-byte packets, traffic drop is seen at 90% and beyond of the line rate.
For 95-byte packets, traffic drop is seen at 95% and beyond of the line rate.
Traffic is dropped when:
Traffic is sent on a VRF interface.
Traffic is sent across layer 2 and layer 3.
However, traffic is not dropped when the packet size is greater than 100 bytes, even if the packets are sent bidirectionally at the line rate.
Effective with Cisco IOS XE Everest 16.6.1, the Port-channel (PoCH) scale is reduced to 24 from 48 for Cisco ASR 900 RSP3 module.

The PoCH scale for Cisco ASR 907 routers is 48. |
