Find instructions for configuring Shared
Ethernet Adapters.
To configure a Shared Ethernet Adapter
using the HMC, version 7 release 3.4.2 or later, see
Creating a shared Ethernet
adapter for a Virtual I/O Server logical partition
using the Hardware Management Console.
To configure a Shared Ethernet Adapter
using versions prior to the HMC, version 7 release
3.4.2, complete the following steps from the Virtual I/O
Server command-line interface:
- Verify that the virtual
Ethernet trunk adapter is available by running the following command:
lsdev -virtual
- Identify the appropriate
physical Ethernet adapter that will be used to create the Shared Ethernet Adapter by running the following
command:
lsdev -type adapter
Notes:
- Ensure that TCP/IP is not configured on the interface for the
physical Ethernet adapter. If TCP/IP is configured, the mkvdev command in the next step fails.
- You can also use a Link Aggregation, or EtherChannel, device as the Shared
Ethernet Adapter.
- If you plan to use the Host Ethernet
Adapter or Integrated Virtual Ethernet with the Shared Ethernet Adapter, ensure that you use the Logical
Host Ethernet Adapter to create the Shared Ethernet
Adapter.
- Configure the Shared Ethernet Adapter by running the following command:
mkvdev -sea target_device -vadapter virtual_ethernet_adapters \
-default DefaultVirtualEthernetAdapter -defaultid SEADefaultPVID
Where:
- target_device
- The physical adapter being used as part of the Shared Ethernet Adapter device.
- virtual_ethernet_adapters
- The virtual Ethernet adapter or adapters that will use the Shared Ethernet Adapter.
- DefaultVirtualEthernetAdapter
- The default virtual Ethernet adapter used to handle untagged
packets. If you have only one virtual Ethernet adapter for this logical
partition, use it as the default.
- SEADefaultPVID
- The PVID associated with your default virtual Ethernet adapter.
For example:
- Verify that the Shared Ethernet Adapter was created by running the
following command:
lsdev -virtual
- Do you plan to access the
Virtual I/O Server from the network with the physical
device used to create the Shared Ethernet
Adapter?
- Yes: Go to step 6.
- No: You are finished with this procedure and do not need
to complete the remaining steps.
- Do
you plan to set bandwidth apportioning by defining a Quality of Service
(QoS)?
- Yes: Go to step 11 to enable the Shared Ethernet Adapter device to prioritize traffic.
- No: Go to step 9 to configure a TCP/IP
connection.
- Do
you plan to define IP addresses on any VLANs other than the VLAN specified by
the PVID of the Shared Ethernet Adapter?
- Yes: Go to step 8 to create VLAN
pseudo-devices.
- No: Go to step 9 to configure a TCP/IP
connection.
- To
configure VLAN pseudo-devices, complete the following steps:
- Create a VLAN
pseudo-device on the Shared Ethernet Adapter by
running the following command:
mkvdev -vlan TargetAdapter -tagid TagID
Where:
- TargetAdapter is the Shared Ethernet Adapter.
- TagID is the VLAN ID that you defined when
creating the virtual Ethernet adapter associated with the Shared Ethernet Adapter.
For example, to create a
VLAN pseudo-device using the Shared Ethernet Adapter
ent3 that you just created with a VLAN ID of 1,
type the following command: mkvdev -vlan ent3 -tagid 1
- Verify that the VLAN
pseudo-device was created by running the following command:
lsdev -virtual
- Repeat this step for
any additional VLAN pseudo-devices that you need.
- Run the following command to configure the first TCP/IP
connection. The first connection must be on the same VLAN and logical
subnet as the default gateway.
mktcpip -hostname Hostname -inetaddr Address -interface Interface -netmask \
SubnetMask -gateway Gateway -nsrvaddr NameServerAddress -nsrvdomain Domain
Where:
- Hostname is the host name of the
Virtual I/O Server
- Address is the IP address you
want to use for the TCP/IP connection
- Interface is the interface
associated with either the Shared Ethernet Adapter
device or a VLAN pseudo-device. For example, if the Shared
Ethernet Adapter device is ent3, the associated interface is en3.
- Subnetmask is the subnet mask
address for your subnet.
- Gateway is the gateway address
for your subnet.
- NameServerAddress is the address
of your domain name server.
- Domain is the name of your
domain.
If you do not have additional VLANs, then you are finished
with this procedure and do not need to complete the remaining step.
- Run the following command to
configure additional TCP/IP connections:
chdev -dev interface -perm -attr netaddr=IPaddress -attr netmask=netmask
-attr state=up
When using this command, enter the interface (enX) associated with either the Shared
Ethernet Adapter device or VLAN pseudo-device.
- Enable the
Shared Ethernet Adapter device to prioritize traffic.
Client logical partitions must insert a VLAN priority value in their VLAN
header. For AIX® clients, a VLAN pseudo-device must
be created over the Virtual I/O Ethernet Adapter, and the VLAN priority
attribute must be set (the default value is 0). Do the following steps to enable
traffic prioritization on an AIX client:
- Set the Shared
Ethernet Adapter qos_mode attribute to either strict or loose mode. Use
one of the following commands: chdev -dev <SEA device name> -attr qos_mode=strict or chdev -dev <SEA device name> -attr
qos_mode=loose. For more information about the modes, see Shared Ethernet Adapter.
- From the HMC, create a Virtual I/O
Ethernet Adapter for the AIX client with all of the
tagged VLANs that are required (specified in the Additional
VLAN ID list). Packets sent over the default VLAN ID (specified in
the Adapter ID or Virtual LAN ID field) will not be tagged as VLAN;
therefore, a VLAN priority value cannot be assigned to them.
- On the AIX client, run the smitty vlan command.
- Select Add a VLAN.
- Select the name of the Virtual I/O
Ethernet Adapter created in step 1.
- In the VLAN Tag ID attribute,
specify one of the tagged VLANs that are configured on the Virtual I/O Ethernet
Adapter that you created in step 1.
- Specify an attribute value (0 - 7)
in the VLAN Priority attribute, which corresponds to the importance the VIOS
should give to the traffic sent over that VLAN pseudo-device.
- Configure the interface over the
VLAN pseudo-device created in step 6.
Traffic sent over the
interface created in step 7 will be tagged as VLAN and its VLAN header will have
the VLAN priority value specified in step 6. When this traffic is bridged by a
Shared Ethernet Adapter that has been enabled for
bandwidth apportioning, the VLAN priority value is used to determine how quickly
it should be sent in relation to other packets at different priorities.
The Shared Ethernet
Adapter is now configured. After you configure the TCP/IP connections for
the virtual adapters on the client logical partitions using the client logical
partitions' operating systems, those logical partitions can communicate with the
external network.
