Solaris -- Network Aggregation

Zuerst sehen wir uns mal die Netzwerk-Schnittstellen an. Die Befehle 'dladm show-link -s' und 'dladm show-dev' bringen dazu brauchbare Ausgaben.

Das Agregat mit 'dladmin' erstellen.

 dladm create-aggr -d bge0 -d bge1 -d bge2 -d bge3 -l off -P L2 1

-d Es koennen soviele Schnittstellen hinzugefuegt werden wie noetig.
-P Policy; Die Richtlinie, die das Load Balancing beschreibt: L2 fuer MAC, L3 fuer IP, L4 fuer src/dest IP
-l off/active/passive bechreibt die Art wie LCAP arbeitet.

LCAP Mode	Description
Passive	The switch does not initiate the channel, but does understand incoming LACP packets. The peer (in active state) initiates negotiation (by sending out an LACP packet) which we receive and reply to, eventually forming the aggregation channel with the peer. This is similar to the auto mode in PAgP.
Active	We are willing to form an aggregate link, and initiate the negotiation. The link aggregate will be formed if the other end is running in LACP active or passive mode. This is similar to the desirable mode of PAgP.
On	The link aggregation is forced to be formed without any LACP negotiation .In other words, the switch will neither send the LACP packet nor process any incoming LACP packet. This is similar to the on state for PAgP.

Mit 'dladm show-link -s' sehen wir uns noch mal die Netzwerk-Schnittstellen an und sehen, dass die Schnittstelle 'aggr' hinzugekommen ist.

Nun kann die Schnittstelle eingebunden und eine IP Adresse hinzugefuegt werden.

 ismine~# ifconfig aggr1 plumb
 ismine~# ifconfig aggr1 192.168.2.30 netmask 255.255.255.0 up
 ismine~# ifconfig -a

Das war es auch schon. Das Agregat ist erstellt und arbeitet.
