Satte upp lite grejer idag och vill ha n\u00e4t redundans mot tv\u00e5 switchar d\u00e5 servern i sig har dubbla NIC. Satte upp detta enligt nedan i Ubuntu 12.04.<\/p>\n

 <\/p>\n

1. Installera programet ifenslave genom att skriva sudo apt-get install ifenslave<\/b>.<\/p>\n

2. Konfigurera din bond detta g\u00f6rs i filen \/etc\/network\/interfaces<\/strong><\/p>\n

Exempel p\u00e5 hur det kan se ut nedan<\/p>\n

auto eth0
\niface eth0 inet manual
\n     bond-master bond0<\/em><\/p>\n

auto eth1
\niface eth1 inet manual
\n     bond-master bond0<\/em><\/p>\n

auto bond0
\niface bond0 inet static
\n     address 192.168.0.1
\n     gateway 192.168.0.254
\n     netmask 255.255.255.0
\n     bond-mode active-backup
\n     bond-miimon 100
\n     bond-lacp-rate 1
\n     bond-slaves none<\/em><\/p>\n

3. Starta om n\u00e4tverket eller starta om servern<\/p>\n

4. F\u00f6r att verifiera bonden s\u00e5 kan man k\u00f6ra cat \/proc\/net\/bonding\/bond0<\/strong>
\nse exempel nedan p\u00e5 hur det kan se ut.
\n
\n
\nEthernet Channel Bonding Driver: v3.7.1 (April 27, 2011)<\/p>\n

Bonding Mode: fault-tolerance (active-backup)
\nPrimary Slave: None
\nCurrently Active Slave: eth0
\nMII Status: up
\nMII Polling Interval (ms): 100
\nUp Delay (ms): 0
\nDown Delay (ms): 0<\/p>\n

Slave Interface: eth0
\nMII Status: up
\nSpeed: 1000 Mbps
\nDuplex: full
\nLink Failure Count: 0
\nPermanent HW addr: 34:40:b5:00:00:00
\nSlave queue ID: 0<\/p>\n

Slave Interface: eth1
\nMII Status: up
\nSpeed: 1000 Mbps
\nDuplex: full
\nLink Failure Count: 0
\nPermanent HW addr: 34:40:b5:11:11:11
\nSlave queue ID: 0
\n<\/em>\n<\/p>\n

Detta kan vara bra att anv\u00e4nda sig av p\u00e5 driftkritiska system som inte f\u00e5r g\u00e5 ner. I detta exemplet har jag visat hur man konfigurerar aktiv \/ standby l\u00e4get. Man kan anv\u00e4nda flera olika bonding-modes se dom olika valen nedan.<\/p>\n

\nMode 0<\/b>
\nbalance-rr
\n
\nMode 1<\/b>
\nactive-backup
\n
\nMode 2<\/b>
\nbalance-xor
\n
\nMode 3<\/b>
\nbroadcast
\n
\nMode 4<\/b>
\n802.3ad
\n
\nMode 5<\/b>
\nbalance-tlb
\n
\nMode 6<\/b>
\nbalance-alb
\n<\/p>\n

F\u00f6r att l\u00e4sa mer om dom olika l\u00e4gen som finns f\u00f6r bonding i linux se wikipedia sidan h\u00e4r<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
