Setting up IBM pSeries p510Q. Networking with VLANs

Материал из RSU WiKi

Some time ago i've tryed to set-up a new server. I have some physical servers (PCs) and 2 LPARs with 2 VLAN interfaces on p510Q Machine.

My configuration is based on article, published on the ibm site: http://www-128.ibm.com/developerworks/eserver/library/es-pwr5-virtualvlan/index.html In my opinion it's the best article from IBM knowledge base about VLANs & VIO configuration.

One LPAR have 2 virtual network interfaces (vlan 2 & 3), other have only one (vlan 2)

This is what i have (exactly):

VIO:

 ent0 (Physical adapter connected to the switch)
 ent2 (PVID=100, Trunk=yes, 802.1Q=yes, VLANs: 2,3) - for SEA
 ent3 (PVID=2, Trunk=no, 802.1Q=no) - for remote administration

LPAR1:

 Virtual adapter 1 (PVID=2)
 Virtual adapter 2 (PVID=3)

LPAR2:

 Vritual adapter (PVID=2)

---

On VIO i've done the following:

 mkvdev -sea ent0 -vadapter ent2 -default ent2 -defaultid=101
 mkvdev -vlan ent4 -tagid 2
 mkvdev -vlan ent4 -tagid 3

 mktcpip -hostname vio1 -inetaddr 172.16.250.1 -interface en3 -netmask 255.255.0.0

INFO: when applying mkvdev -vlan entX -tagid YY, entX must be the SEA adapter, you could find it with command:

$ lsdev | grep "Shared Ethernet Adapter" 
ent4             Available   Shared Ethernet Adapter

On LPARs (I'm using SuSE):

lpar1:

 eth0: 172.16.250.3/255.255.0.0
 eth1: 172.30.0.1/255.255.0.0

lpar2:

 eth0: 172.16.250.4/255.255.0.0

Also i have some physical machines from both subnets (172.16 & 172.30).

Everybody are able to see & ping each other. HOORAY! :)
