sFlow independent configuration allows the user to configure the sFlow source and agent addresses independently of one another. This feature fixes the limitations of “sflow source-interface” where the address it uses is indeterminate when the interface has multiple addresses assigned.

On supported devices, a port-channel can be configured as a mirroring destination for both ingress and egress source directions. Traffic mirrored to a port-channel is load-balanced based on the global port-channel load-balance configuration, which is the same for other port-channels.

Synchronous Ethernet (SyncE) provides support for frequency synchronization over Ethernet between devices traceable to an external frequency reference, like a primary reference clock, as specified in ITU G.8261.

Forwarding destination prediction enables visibility into how a packet is forwarded through the switch and allows

This feature adds support for a selected set of configured interfaces to collect egress flow samples. Egress sFlow can be configured on Ethernet and Port-Channel interfaces, and on subinterfaces on select platforms. Hardware acceleration is not currently supported for egress sFlow and all sample processing is performed in software.

This article describes the TAP Aggregation 802.1Q (VLAN) tag stripping feature. This feature allows up to two of the outermost incoming 802.1Q tags to be stripped, and can be configured on a traffic steering policy or a tool port.
