cumulus@switch:~$ nv set interface swp1 bridge domain default learning on

nv set interface <interface-id> bridge domain <domain-id> stp admin-edge

Turns STP PortAdminEdge on or off on the bridged interface. PortAdminEdge is equivalent to the PortFast feature offered by other vendors. It enables or disables the initial edge state of a port in a bridge. All ports with PortAdminEdge on bypass the listening and learning states and go straight to forwarding.

Command Syntax

Version History

Introduced in Cumulus Linux 5.0.0

Example

cumulus@switch:~$ nv set interface swp1 bridge domain default stp admin-edge on

nv set interface <interface-id> bridge domain <domain-id> stp auto-edge

Turns STP AutoEdge on or off on the bridged interface. PortAutoEdge is an enhancement to the standard PortAdminEdge (PortFast) mode, which allows for the automatic detection of edge ports. PortAutoEdge enables and disables the auto transition to and from the edge state of a port in a bridge.

When a port with PortAutoEdge receives a BPDU, the port stops being in the edge port state and transitions into a normal STP port. When the interface no longer receives BPDUs, the port becomes an edge port, and transitions through the discarding and learning states before it resumes forwarding.

Command Syntax

Version History

Introduced in Cumulus Linux 5.0.0

Example

cumulus@switch:~$ nv set interface swp1 bridge domain default stp auto-edge on

nv set interface <interface-id> bridge domain <domain-id> stp bpdu-filter

Turns bpdufilter on or off on a bridge domain. When on, bpdufilter filters BPDUs in both directions.

Command Syntax

Version History

Introduced in Cumulus Linux 5.0.0

Example

cumulus@switch:~$ nv set interface swp1 bridge domain default stp bpdu-filter on

nv set interface <interface-id> bridge domain <domain-id> stp bpdu-guard

Turns BPDU guard on or off on the bridged interface to protect the spanning tree topology from an unauthorized device affecting the forwarding path. For example, if you add a new host to an access port off a leaf switch and the host sends an STP BPDU, BPDU guard protects against undesirable topology changes in the environment.

Command Syntax

Version History

Introduced in Cumulus Linux 5.0.0

Example

cumulus@switch:~$ nv set interface swp1 bridge domain default stp bpdu-guard on

nv set interface <interface-id> bridge domain <domain-id> stp network

Example

cumulus@switch:~$ nv set interface swp1 bridge domain default stp vlan 10 priority 240

nv set interface <interface-id> bridge domain <domain-id> stp vlan <vid> path-cost

Configures the interface path cost for a VLAN to influence the spanning tree forwarding path. You can specify a path cost between 1 and 200000000.

Command Syntax

Version History

Introduced in Cumulus Linux 5.6.0

Example

cumulus@switch:~$ nv set interface swp1 bridge domain default stp vlan 10 path-cost 4000

nv set interface <interface-id> bridge domain <domain-id> stp path-cost

Configures the path cost for an interface in the bridge to influence the spanning tree forwarding path. You can specify a value between 1 and 200000000.

For PVRST mode, the port cost for a VLAN takes precedence over the cost for a port. If you do not configure the port cost for a VLAN, Cumulus Linux applies the port cost to all the interfaces in the VLAN. If you do not configure either the port cost for a VLAN or the cost for a port, Cumulus Linux bases the port cost on the link speed.

Command Syntax

Version History

Introduced in Cumulus Linux 5.6.0

Example

cumulus@switch:~$ nv set interface swp1 bridge domain default stp path-cost 4000

nv set interface <interface-id> bridge domain <domain-id> untagged

Configures the VLAN in which untagged packets ingress this bridged interface. Egress packets are always tagged. You can set a value between 1 and 4094, none, or auto. If you specify none, the switch drops untagged packets.

You can run this command to force all SVIs on all bridges to always be UP even when all member ports are DOWN, which is beneficial if you want to perform connectivity testing.

You can specify on or off.
