## Properties

Table 73.

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---

    ageing-time

    uint32

    300

The Ethernet MAC address aging time, in seconds.

    forward-delay

    uint32

    15

The Spanning Tree Protocol (STP) forwarding delay, in seconds.

    group-forward-mask

    uint32

    0

A mask of group addresses to forward. Usually, group addresses in the range from 01:80:C2:00:00:00 to 01:80:C2:00:00:0F are not forwarded according to standards. This property is a mask of 16 bits, each corresponding to a group address in that range that must be forwarded. The mask can't have bits 0, 1 or 2 set because they are used for STP, MAC pause frames and LACP.

    hello-time

    uint32

    2

The Spanning Tree Protocol (STP) hello time, in seconds.

    interface-name

    string

Deprecated in favor of connection.interface-name, but can be used for backward-compatibility with older daemons, to set the bridge's interface name.

    mac-address

    byte array

If specified, the MAC address of bridge. When creating a new bridge, this MAC address will be set. If this field is left unspecified, the "ethernet.cloned-mac-address" is referred instead to generate the initial MAC address. Note that setting "ethernet.cloned-mac-address" anyway overwrites the MAC address of the bridge later while activating the bridge. Hence, this property is deprecated. Deprecated: 1

    max-age

    uint32

    20

The Spanning Tree Protocol (STP) maximum message age, in seconds.

    multicast-snooping

    boolean

    TRUE

Controls whether IGMP snooping is enabled for this bridge. Note that if snooping was automatically disabled due to hash collisions, the system may refuse to enable the feature until the collisions are resolved.

    priority

    uint32

    32768

Sets the Spanning Tree Protocol (STP) priority for this bridge. Lower values are "better"; the lowest priority bridge will be elected the root bridge.

    stp

    boolean

    TRUE

Controls whether Spanning Tree Protocol (STP) is enabled for this bridge.
