When the virtual switch is created, the default
setting
is the Virtual Ethernet Bridging (VEB) mode. You can change the virtual
switch mode to Virtual Ethernet Port Aggregation (VEPA) by using the Hardware Management Console (HMC).
The HMC Classic interface is
not supported in Hardware Management Console (HMC) Version 8.7.0, or later. The functions that were previously
available in the HMC Classic interface are now available in
the HMC Enhanced+ interface.
For more information about changing a virtual switch when the HMC is at version 8.7.0, or later, see Changing a virtual
switch.
To change the virtual switch mode setting,
complete the following steps:
- In the
navigation pane, expand Systems Management,
click Servers, and select the server on which
the logical partition is located.
- In the Tasks pane,
click .
- Click .
- Select VEPA from
the list.
- Click OK.
Note: If the switch supports the VEPA mode but does not support the
IEEE 802.1 Qbg
standard, setting the switch to the VEPA mode fails. You can force
the switch to be set to VEPA mode
by running the chhwres command from the HMC command line and specifying
the --force
option. You must also manually set the physical switch to the VEPA
mode by using the interfaces that
are provided by the switch. However, if setting the switch mode to
VEPA fails because of reasons
such as a Resource Monitoring and Control (RMC) connection failure,
or an incorrect or older version
of the Virtual I/O Server (VIOS), you must not use
the --force option.
