## Properties

Table 39.

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.
    name
    string
    bridge
| The setting's name, which uniquely identifies the setting within the connection. Each setting type has a name unique to that type, for example "ppp" or "wireless" or "wired".
    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.
