z/VM: CP Commands and Utilities Reference - z/VM - IBM

PORTType TRUNK
defines the type of connections that are established by the userid to be a trunk
port. The guest is VLAN aware and sends and receives only tagged traffic for
those VLANs to which the guest is authorized. If the guest is also authorized to
the defvid, untagged traffic sent or received by the guest is associated with the
default VLAN ID of the virtual switch.
VLAN vlanid
identifies the VLAN ID to be used to restrict traffic across the adapter userid
connected to switchname. When VLAN is used with GRANT, userid is
authorized to connect to the virtual switch and vlanid is used as a filter.
Specifying GRANT with one or more VLAN IDs adds to the set of VLAN IDs
associated with userid. A limit of four vlanids can be associated with userid in
the CP access list.
vlanid is a number from 1 to 4094.
SET VSWITCH
If VLAN vlanid is not specified, the default VLAN for the userid is the default
VLAN ID as specified on the DEFINE VSWITCH command or statement.
If an External Security Manager (ESM) is in control of the virtual switch, it may
override the CP access list.
REVOKE userid
specifies userid is removed from the CP access list for this virtual switch. This
prevents user userid from connecting an adapter to virtual switch switchname.
Existing connections to the virtual switch are not affected. If an External
Security Manager (ESM) is in control of the virtual switch, it may override the
CP access list.
PORTname portname
is a 1- to 8-character name that identifies the OSA Express adapter. You can
specify a maximum of 3 port names. Multiple port names are used when
different port names are needed for the multiple rdevs specified on the RDEV
operand. See Usage Note 5 on page 1423 for more information.
RDEV rdev
is a real device address to be used to connect the virtual switch to a QDIO
OSA Express device. Specify each real device number as a 1- to 4-digit
hexadecimal number. You can specify a maximum of 3 real device numbers. If
you specify more than one device number, each must be separated from the
others by at least one blank.
Each real device address represents a trio of devices. For example, specifying
RDEV 111 222 333 means that the first devices, 111-113, are used to provide
the connection to the real hardware LAN segment. If there is a problem with the
connection, devices 222-224 are used next to provide the connection, and if
those devices fail to connect, devices 333-335 are used. This feature provides
dynamic recovery for OSA Express device failures.
RDEV NONE means that the virtual switch should not be connected to the real
LAN segment.
CONnect
indicates that the device identified by the RDEV keyword must be activated,
and traffic must flow through the device to the real LAN segment. If an error
occurs with one of the backup devices, issue the SET VSWITCH switchname
CONNECT command to refresh the backup device once the problem is
corrected.
