The sFlow VPLS extension adds support for providing VPLS-related information to sFlow packet samples, for VPLS forwarded traffic. Specifically, for customer traffic ingressing on a CE-facing PE interface in a VPLS deployment that uses statically configured LDP pseudowires, information such as the name of the VPLS instance and the ID of the pseudowire that the packet will egress over will be included in the sFlow datagram.

The purpose of this feature is to mitigate multicast traffic loss when a switch that is using PIM sparse mode as its multicast routing protocol is going under maintenance.

The pre-existing "show sflow" command has a "Number of datagrams" field that indicates the total number of datagrams sent to all sFlow collectors. This feature will add finer granularity by allowing users of software sFlow to view the number of datagrams sent to each sFlow collector.

The pre-existing "show sflow" command has a "Number of samples" field that indicates the total number packets sampled across all sFlow enabled interfaces. This feature will add finer granularity by allowing users of software sFlow to view the number of packets sampled at each sFlow enabled interface in the ingress and egress directions.

This feature allows for the configuration of password requirements when creating or modifying local user accounts. Specifically, policies can necessitate that passwords meet the following requirements:
