Linux Bridge är en kernel-modul som introducerades i kernel 2.2 och administreras med kommandot brctl. Man kan göra om portar på en Linuxmaskin till switchportar. Se även Open vSwitch och Linux VXLAN.
Installation
sudo apt-get install bridge-utils sudo yum install bridge-utils
Konfiguration
ifconfig eth0 0.0.0.0 ifconfig eth1 0.0.0.0 brctl addbr bridge1 brctl addif bridge1 eth0 eth1 brctl show
brctl delif bridge1 eth0
/etc/network/interfaces
auto bridge iface bridge bridge-vlan-aware yes bridge-ports eth0 eth1 eth7 bridge-vids 3 4 6-10 #allowed vlan bridge-pvid 1 #native vlan bridge_waitport 0 #portfast bridge-stp on mstpctl-treeprio 20480
VLAN
aptitude install vlan ifenslave echo "8021q" >> /etc/modules
Spanning-Tree
sudo brctl stp bridge1 on
/etc/network/interfaces
auto bond0 iface bond0 inet manual up ifconfig bond0 0.0.0.0 up slaves eth0 eth1 bond-mode 4 #bond-mode 4 = 802.3ad bond-miimon 100 bond-downdelay 200 bond-updelay 200 bond-lacp-rate 1 bond-xmit-hash-policy layer2+3
Kolla packet
cat /proc/net/bonding/bond0
MAC Table
Man kan kolla MAC-tabellen på en brygga med följande kommando:
brctl show brctl showmacs <bridge_name>
