Most existing Junos OS configuration statements and operational mode commands
are supported (for example, interfaces, VLANs, protocols, and firewall filters).
To view QFabric system components and check connectivity of the system, issue the
show fabric administration inventory
commands.
•
Alias configuration for Director devices, Interconnect devices, and Node
devices
—Enables you to set user-defined aliases for QFabric system Director devices,
Interconnect devices, and Node devices to facilitate usability of the QFabric system
as it scales. Aliased names appear in the output of many QFabric system operational
commands, such as
show fabric administration inventory
. To map the hardware serial
number of a Director device, Interconnect device or Node device to a user-defined
name, see
“Configuring Aliases for the QFabric System” on page 382 .
• Node group configuration —Enables you to cluster several Node devices together to
provide redundancy, resiliency, and high availability at the ingress and egress points
of the QFabric system. There are two types of Node groups you can configure:
•
Redundant server Node group —Enables the grouped Node devices to connect the
QFabric system to local servers and storage devices. A redundant server Node group
can contain a maximum of two Node devices and supports LAG connections that
can span both devices.
NOTE: The Node devices in a redundant server Node group must be of
the same type, either a QFX3500 Node or a QFX3600 Node. You cannot
add a QFX3500 and a QFX3600 Node device to the same redundant
server Node group.
• Network Node group —Enables the grouped Node devices to connect the QFabric
system to external networks and run routing protocols such as BGP and OSPF. A
network Node group can contain up to eight Node devices and supports LAG
connections.
NOTE:
•
The name of the network Node group in the default partition, NW-NG-0,
is preset. You must use this name when adding Node devices to the
network Node group. You cannot specify a different name.
• When you configure routing protocols on the QFabric system, you must
use interfaces from the Node devices assigned to the network Node
group. If you try to configure routing protocols on interfaces from the
Node devices assigned to server Node groups, the configuration commit
operation fails.
To configure a redundant server Node group, include two Node devices with the
node-device node-device-name statement at the [edit fabric resources node-group
node-group-name ] hierarchy level.
To configure a network Node group, include the network-domain statement at the [edit
fabric resources node-group NW-NG-0] hierarchy level. In addition, include between
