You can determine the disk I/O speed of a node in the Junos Space fabric by logging in
to the node as an admin user and executing the following command:
dd if=/dev/zero of=./test bs=8k count=500000
where test is the name of the file to which the command output is copied.
The following is the command output:
500000+0 records in
500000+0 records out
4096000000 bytes (4.1 GB) copied, 15.944 seconds, 257 MB/s
where 257 MB/s indicates the I/O speed of the disk.
We recommend that you delete the test file after determining the I/O speed.
NOTE: The minimum disk I/O speed recommended for Junos Space Virtual
Appliance is 200 Mbps.
Can I Change the IP address of a Junos Space Node That Has Been deployed?
You can do modify the IP address and other settings from the Administration workspace
in Junos Space Network Management Platform; refer to the Modifying the Network Settings
of a Node in the Junos Space Fabric (in the Workspaces Feature Guide) for details.
You can also modify the IP address and other settings by using the Junos Space CLI. For
more information, refer to Changing Network and System Settings for a Junos Space
Appliance (in the Junos Space Appliance documentation) and Changing the Network and

Frequently Asked Questions
System Settings of a Junos Space Virtual Appliance (in the Virtual Appliance
documentation).
After Installing a Junos Space Virtual Appliance, Why Do I Get a “Login Incorrect” Error When I
Try To Log In To the Virtual Appliance From the Console?
This could occur because of a slow VMware connection, which can occur when you
connect over a VPN or a slow wireless connection. To address this problem you can try
increasing the “type delay” for slow connections to virtual machine consoles by changing
the keyboard.typematicMinDelay setting in the the *.VMX file for the virtual machine. You
can edit the *.VMX files directly, but we recommend that you configure this value for a
virtual machine template by using the vSphere Client. For additional information on the
keyboard.typematicMinDelay setting, access the VMware Knowledge Base article 196 at
http://kb.vmware.com/selfservice/microsites/microsite.do .
Can You Install Junos Space Network Management Platform on NSM3000?
From Junos Space Network Management Platform Release 12.2 onward, Junos Space
can be run on NSM3000, which is an appliance version of Network and Security Manager
(NSM).
NOTE: The NSM3000 shares the same hardware specifications as the JA1500
Junos Space Appliance.
To install Junos Space on an NSM3000, follow the steps in the Installing a Junos Space
Image on a Junos Space Appliance by Using a USB Drive topic (in the Junos Space Appliance
documentation).

What Minimum Configuration Do Network Devices Require for Junos Space Network
Management Platform to Manage Them?
To discover and manage network devices, Junos Space software requires that the devices
have the following minimum configuration:
•
An in-band or out-of-band static management IP address configured on the device.
This IP address must be reachable from the Junos Space server.
•
A user ID belonging to the superuser class or a class that has at least the permissions
mentioned in the Knowledge Base article KB21884 exists on the device. Junos Space
uses this user ID to authenticate the SSH connection with the device.
•
SSH version 2 is enabled on the device. You can use the following command to enable
SSH version 2 on the device:
set system services ssh protocol-version v2
•
Ping and SNMP are enabled on the device. Ping and SNMP are used to confirm whether
the device is reachable and whether it is a Juniper Networks device before the device
is managed by Junos Space.
•
SNMP is enabled on the device with appropriate read-only version 1 (SNMPv1), version
2C (SNMPv2C), or version 3 (SNMPv3) credentials if you plan to use SNMP to probe
devices as part of the device discovery process.
NOTE:
•
For device-initiated connections, you do not need to configure a static
management IP address on the device. However, some features of Junos
Space Platform might not be available.
•
Although ping and SNMP are not strictly required, we recommend that you
enable both on the device. SNMP is used for the Network Monitoring
functionality of Junos Space Platform, whereas ping speeds up the process
of device discovery when you are discovering multiple IP addresses.
Which Port on the Junos Space node Does a Device Connect To?
Devices managed by Junos Space connect to port 7804 on the Junos Space node.
26
Copyright © 2016, Juniper Networks, Inc.
Chapter 1: Junos Space Network Management Platform FAQ
Does Using Junos Space To Discover Devices That Are Connected To AI-Scripts and SRC Affect
Those Connections?
No. Using Junos Space Network Management Platform to discover devices that are
connected to AI-Scripts and Session and Resource Control (SRC) does not affect the
existing connections these devices might have. When Junos Space discovers and manages
these devices, it automatically configures them to connect to the Junos Space server by
adding a new client entry at the [edit system services outbound-ssh] hierarchy level.
Does Junos Space Support IPv6?
From Junos Space Network Management Platform Release 14.1R2 onward, you can
discover and manage devices by using IPv6 addresses. Junos Space Platform supports
the management of devices configured with only IPv4 addresses, only IPv6 addresses,
or both.
From Junos Space Network Management Platform Release 15.1R1 onward, you can
configure nodes in the Junos Space fabric with only IPv4 addresses or both IPv4 and IPv6
addresses (dual stack).
For more information, see Junos Space IPv6 Support Overview (in the Workspaces Feature
Guide).

How Is Connecting To Devices Running Worldwide Junos OS Different From Connecting To
Devices Running the Domestic Version of Junos OS?
Devices running the worldwide version of Junos OS use the Telnet protocol instead of
the SSH protocol (SSH version 2) for communication. Because Junos Space does not
support Telnet, it uses an adapter to act as a medium to connect to these devices. For
more information, see Worldwide Junos OS Adapter Overview (in the Workspaces Feature

How Does Junos Space Gather Topology Data?
Junos Space Network Management Platform uses SNMP to discover network elements
(devices, links, and ports) that are connected to the specified target devices and subnets.
The Junos Space server uses SNMP probes to contact the targeted devices and obtain
the relevant management information base (MIB) needed to compute the topology.
How Is Topology Discovery Different From Device Discovery?
The topology discovery job discovers both devices and how they are connected (link
association).
The device discovery job discovers only devices.

•
Can a Junos Space fabric Contain a Mix of Hardware Appliances and Virtual
Appliances? on page 29
Can a Junos Space Fabric Contain Both JA1500 and JA2500 Junos Space Appliances?
Yes. A Junos Space fabric can contain both JA1500 and JA2500 Junos Space Appliances,
provided all the nodes are installed with the same version of Junos Space Network
Management Platform and, if applicable, Junos Space applications.
We recommend that you configure the JA2500 appliance as the primary VIP node because
the JA2500 appliance has better hardware specifications than the JA1500 appliance.
Can a Junos Space fabric Contain a Mix of Hardware Appliances and Virtual Appliances?
Yes. A Junos Space fabric can contain only hardware appliances (JA1500, JA2500, or
both), only virtual appliances, or a combination of both hardware and virtual appliances.

Frequently Asked Questions
What Steps Do I Need To Take When One of the High-Availability Nodes in the Cluster Shows
the Status “Down”?
1.
Collect all troubleshooting data and logs for the fabric (cluster) from the Space
Troubleshooting page (Administration > Space Troubleshooting).
NOTE: For information about how to download the troubleshooting data
and log files, refer to the following topics (in the Workspaces Feature
Guide):
•
Downloading the Troubleshooting Log File in Server Mode
•
Downloading the Troubleshooting Log File in Maintenance Mode
•
Downloading Troubleshooting System Log Files Through the Junos Space
CLI
These logs might be needed later for troubleshooting.
2. Try to log in to the console of the node that is down.
If you are able to log in to the console, proceed to step 3. If you are unable to log in to
the console, go to step 4.
3. If you are able to log in to the console:
a. Using the Junos Space Settings menu, access the debug shell.
b. Check whether the jmp-watchdog and jboss services are up by executing the
following command: service service-name status, where service-name is the name
of the service; for example, jboss.
c.
•
If the services are down:
i.
Restart the services by executing the following command: service service-name
restart, where service-name is the name of the service; for example, jboss.
ii. Wait for 15 to 20 minutes and check the status of the node on the
Administration > Fabric page.
If the node status is still Down, go to step 4
•
If the services are up, but the node status is still Down, open a case with the
Juniper Networks Technical Assistance Center (JTAC).
4. If you are unable to log in to the console or if the node status is still Down after
restarting the services, reboot the node.
For more information, see the Shutting Down or Rebooting Nodes in the Junos Space
Fabric topic (in the Workspaces Feature Guide).
5. Wait for 15 to 20 minutes and check the status of the node in the Administration >
Fabric page.
If the node status is still down, proceed to step 6.
30
Copyright © 2016, Juniper Networks, Inc.
Chapter 1: Junos Space Network Management Platform FAQ
6. Delete the node from the Junos Space fabric (on the Administration > Fabric page).
NOTE: If another node is available in the fabric that can be prompted as
a high availability node, you are prompted to enable high availability on
that node before deleting the node that is down.
For more information, see Deleting a Node from the Junos Space Fabric (in
the Workspaces Feature Guide).
7. For the deleted node, depending on whether you are using a virtual appliance or a
hardware appliance, you can redeploy the virtual appliance or reimage the hardware
appliance by using a USB drive. For more information, refer to the Junos Space
hardware or virtual appliance documentation at
http://www.juniper.net/techpubs/en_US/release-independent/junos-space/index.html.
NOTE: Ensure that the Junos Space version that you are reimaging or
redeploying is the same version as the Junos Space version running on
other nodes in the fabric.
8. (Optional) If you are unable to reimage the hardware appliance or redeploy the virtual
appliance, you might need to procure a new hardware or virtual appliance as a
replacement.
9. Reconfigure the hardware or virtual appliance with exactly the same network settings
that were previously configured.
10. Navigate to the Fabric page (Administration > Fabric) and add the node back to the
fabric.
For more information, see the Adding a Node to an Existing Junos Space Fabric topic
(in the Workspaces Feature Guide).
What Algorithm Does the Apache HTTP Load Balancer Use To Distribute Load Among Nodes
in the Cluster?
Junos Space uses the mod_proxy load balancer module within the Apache HTTP server.
The load balancer module is configured to use the default load-balancing method
(lbmethod=byrequests), which provides a weighted round-robin algorithm. However,
because all nodes in the cluster have the same weight, this means that a round-robin
strategy is used for load distribution. The load balancer is also configured to use sticky
sessions (using the JSESSIONID cookie), which ensures that all HTTP requests that are
part of the same login session are forwarded to the same node in the cluster.
How Do I Determine Which Node in the Cluster Is Handling My Junos Space Platform UI Session?
Open your browser’s dialog box that lists all the stored cookies. Find the website with
the VIP address of the Junos Space cluster and expand it. The contents of the cookie
named JSESSIONID includes the hostname of the node that is serving your current session.
Copyright © 2016, Juniper Networks, Inc.
31
Frequently Asked Questions
The following is an example of the JSESSIONID cookie:
Name: JSESSIONID
Content: "dfyRgUZaYqfXEhDq3YOnKaKAVz+qxdl84D1qfnV0lF1
Qt3c9fxQDfhMnN7xSSK0dqg8_.space-0050568c1466:server1"
Host: 192.0.2.0
Path:/
Send for : Encrytpted sessions only
Expires: At end of the session
In this example, space-0050568c1466 is the hostname of the node serving the session.
How Do I Determine Which Device Connections Are Being Handled By a Node?
1.
Connect to the node by using SSH.
2. Using the Junos Space Settings Menu, access the debug shell.
3. Execute the netstat -tnp | egrep ":7804|:22|:23" | grep ESTABLISHED | grep java
command.
A sample output of this command is shown in Figure 1 on page 32
The output displays one line for each device connected to this node. In this example,
the node includes two device initiated connections and five Junos Space initiated
connections. The IP addresses of the devices are displayed in the fifth column.
Figure 1: Sample Output of a netstat Command Executed on a Node
How Can I Simulate a Virtual IP (VIP) Failover?
To simulate a VIP failover, you can shut down the heartbeat service on the node that
currently owns the VIP.
1.
Log in to the console of the node.
2. Using the Junos Space Settings Menu, access the debug shell.
3. At the command prompt, run the following command: service heartbeat stop.
The heartbeat service on this node shuts down and a message is automatically sent
to its peer node. The peer node takes over the VIP in response to this message.
4. Monitor the /var/log/messages file on both nodes to view the log entries related to
the failover.
As the messages show, VIP failover is almost instantaneous in this case.
