Pica8 PicOS supports Layer 2 switching protocols, including: STP, RSTP, MSTP, MAC learning, and Q-in-Q. PicOS also supports several Layer 3 protocols, including: static routing, RIPv2, OSPF, IGMP, PIM-SM, and IPv6. This guide provides instructions and examples for configuring switches and controllers. Intended for system administrators, this guide assumes a working knowledge of Layer 2 and Layer 3 protocols.
PicOS can run in 2 different modes of operation:
- Â Open vSwitch (OVS) Mode: In this mode, PicOS is dedicated and optimized for OpenFlow applications.
- Â Layer 2/Layer 3 (L2/L3) Mode:Â In this mode, PicOS can run switching and routing protocols, as well as OpenFlow applications.
In OVS mode, L2/L3 daemons are not running, and the system is fully dedicated to OpenFlow and OVS. In L2/L3 mode, L2/L3 daemons are running, and OVS can also be used if OpenFlow in Crossflow Mode is activated.
This chapter assumes that user is running PicOS L2/L3 mode. Please see PICOS Mode Selection to learn how to switch between L2/L3 and OVS modes.
Warning:
On FS S5810 Series and S5860 Series switches, run "copy running-config startup-config" command when set L2 / L3 CLI commands. Otherwise, the L2 / L3 configuration will be lost after PicOS reboot. For detail, please refer to Configuration Saving Guide.
