LACP kasutamine
Allikas: Kuutõrvaja
Sisukord
Sissejuhatus
Ethernet interface bonding tehnika võimaldab teatud tingimustel kasutada mitut arvutisse paigaldatud füüsilist võrguseadet ühe loogilise seadmena.

Tarkvara paigaldamine
Vajalik tarkvara sisaldub operatsioonisüsteemi tuumas, juhtprogrammi ifenslave paigaldamiseks sobib öelda
# apt-get install ifenslave-2.6
Seadistamine
Bonding seadme nimeks on tavaliselt bond0 ning LACP bonding (mitte segi ajada failover-bond seadmega) seadistatakse /etc/network/interfaces sektsiooniga
auto bond0 iface bond0 inet static address 10.0.3.87 netmask 255.255.255.0 slaves eth1 eth2 bond_mode 802.3ad bond_miimon 100 bond-lacp-rate 4
Vastav seadistamine käsurealt võiks toimuda nt selliselt
# modprobe bonding mode=802.3ad lacp_rate=1 miimon=100 xmit_hash_policy=layer3+4 # ifconfig bond0 10.0.3.87 netmask 255.255.0.0 # ifenslave bond0 eth1 eth2
Bonding seadme eemaldamiseks sobib öelda
# ifenslave -d bond0 eth1 eth2 # rmmod bonding
Bonding seadme omadusi saab vaadata
# cat /proc/net/bonding/bond0

LACP seadme moodustamiseks sobib öelda nt

kus
- trunk id järel on esitatud komponentide mac aadressid
- tundub, et mõlema komponendi olemasolul reeglina ühendusega seotud väljuvad paketid liiguvad läbi ühe seadme ja sisenevad läbi teise

Märkused
- Tundub, et bondinguks ettevalmistatud switchi kaudu arvutit ei õnnestu üle PXE alglaadida.
