Owners Manual

Add a Linux bond interface to a VLAN domain—bond1 is a Linux interface that maps to a LAG port in the NPU. Use the command to add

the LAG port to the VLAN associated with the bridge instance in the NPU.

$ ip link add link bond1 name bond1.200 type vlan id 200

$ brctl addif br200 bond1.200

Remove VLAN member from VLAN

$ brctl delif br200 e101-001-0.100

Delete VLAN

$ brctl delbr br200

Link layer discovery protocol

OpenSwitch OPX supports the link layer discovery protocol (LLDP) daemon on Linux interfaces.

Spanning-tree provisioning

OpenSwitch OPX supports spanning-tree provisioning (STP) using the CPS API including:

• Create a new spanning-tree group

• Add VLANs to a spanning-tree group

• Remove VLANs from a spanning-tree group

• Change the STP state of ports mapped to a spanning-tree group

• Delete a spanning-tree group

This enables OpenSwitch OPX to run any of the spanning-tree protocols such as STP, RSTP, PVST, and MSTP.
