Usage¶

You can manage bridges from Linux or from the fast path.

Managing bridges from Linux¶

The following Linux commands allow to manage bridge devices (assuming Linux - Fast Path Synchronization is started).

Loading required modules¶

Load required modules:
```
# modprobe bridge
```

Creating a bridge device¶

# brctl addbr br0

This creates a new device (br0).

Displaying information about a bridge device¶

# brctl show br0

Deleting a bridge device¶

# brctl delbr br0

Adding a port to the bridge¶

# brctl addif br0 eth0

Forcing promiscuity in the fast path¶

This feature is meant for Linux < 3.13.

# ip link set eth0 promisc on

Deleting a port from a bridge¶

# brctl delif br0 eth0

Managing bridges from the fast path¶

The fp-cli commands below allow you to manage Fast Path Ethernet Bridge instances.

Setting port features from a bridge¶

Synopsis

bridge-port-set IFNAME [hairpin|learning|flooding <on|off>]

IFNAME: Name of the port interface.

Example

<fp-0> bridge-port-set eth0 hairpin on
eth0-vr0: master br0-vr0
        state: forwarding
        features: hairpin learning flooding

Displaying bridge interfaces¶

Synopsis

bridge

Example

<fp-0> bridge
Bridge interfaces:
br0-vr0:
        eth0-vr0: master br0-vr0
                state: forwarding
                features: learning flooding
        eth1-vr0: master br0-vr0
                state: forwarding
                features: learning flooding

Displaying a bridge interface’s FDB entry¶

Synopsis

bridge-fdb IFNAME

IFNAME: Name of the bridge interface.

Example

<fp-0> bridge-fdb br0
br0-vr0:
 00:30:1b:b4:dc:87 eth0-vr0 local
 00:50:fc:4c:88:e4 eth1-vr0
 00:50:fc:62:ec:c6 eth1-vr0 local
 00:30:1b:b4:df:94 eth0-vr0

Configuring the bridge FDB hitflags refresh policy¶

Synopsis

bridge-fdb-hitflags-set PERIOD MAX_SCANNED MAX_SENT

PERIOD: Period in seconds of FDB checking.
MAX_SCANNED: Maximum number of FDB entries to scan on a given period of time.
MAX_SENT: Maximum number of FDB entries to send over a given period of time.

Example

<fp-0> bridge-fdb-hitflags-set 30 2500 1600

Displaying bridge FDB hitflags parameters¶

Synopsis

hitflags [all|bridge-fdb|...]

No parameter: Display parameters for all categories.
all: Same as with no parameters.
bridge-fdb: Display bridge FDB hitlfags parameters.

Example

<fp-0> hitflags bridge-fdb
Bridge FDB hitflags
  period_in_seconds: 30
  max_scanned: 2500
  max_sent: 1600
