Are policy based routing & IP SLA proprietary to Cisco? I plan to use those services on HP A-series switches. Thx
Other vendors implement similar features with routing policy and Ethernet or MPLS OAM, but you should look at HP's configuration guides to see if they have the specific features that you need. I've used similar features on Juniper and Alcatel Lucent gear, but I don't have experience with HP.
Usually Industry always follow Cisco sooner or later.
From real world prospective you can find both features in almost all vendor flavors now, the naming conventions might be different. Like Cisco's Trunk port in HP world is Tagged port.
