What Minimum Configuration Do Network Devices Require for Junos Space Software
to Manage Them?
For the Junos Space software to discover and manage devices, the following minimum
configuration is expected as a prerequisite on the devices:
•
A static management IP is configured on the device. It could be in-band or out-of-band.
This IP address must be reachable from the Junos Space server.
•
A user ID belonging to the superuser class exists on the device. The Junos Space
software uses this user ID to authenticate the SSH connection with the device.
•
If you plan to use SNMP to probe devices as part of device discovery, SNMP must be
enabled on the device with appropriate read-only V1/V2C/V3 credentials created.
•
SSH v2 is enabled on the device. Use the following command to enable SSH v2.
set system services ssh protocol-version v2

Documentation
•
Ping/SNMP is enabled on the device. Ping/SNMP is used to confirm whether the device
is reachable and whether it is a Juniper Networks device before adding it to the system.

Junos Space Frequently Asked Questions
What Port on the Junos Space Node Does a Device Connect To?
As devices are brought under Junos Space management, they connect to port 7804 on
the Junos Space node.
Does Using Junos Space Software to Discover Devices That Are Connected to AIS and
SRC Affect Those Connections?
When the Junos Space software discovers and manages these devices, it will
automatically configure them to connect to the Junos Space server by having a new
client entry under the system/services/outbound-ssh stanza. This connectivity will not
interfere with any existing connections that these devices might have.
IPv6 and Junos Space
You can use Configuration Editor or Device Templates to configure IPv6 on devices
running Junos Release 10.2 and above.

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?
You might be experiencing a VMware slow connection, which can occur when you connect
over a VPN or slow wireless. To address this problem you can try increasing the type
delay for slow connections to virtual machine consoles by changing the
keyboard.typematicMinDelay setting, which you perform from the .VMX file for the virtual
machine. You can edit the *.VMX files directly, but we recommend that you configure
this value with the vSphere Client for a virtual machine template. For additional
information on the keyboard.typematicMinDelay setting, access the VMware Knowledge
Base at http://kb.vmware.com/selfservice/microsites/microsite.do and search on article

How Does Junos Space Look For a Topology?
Junos Space uses SNMP to discover network elements (devices, links, ports) that are
connected to the specified target devices and subnets. The Junos Space server uses
SNMP probes to contact the targeted devices and get the relevant management
information base (MIB) information needed to compute the topology.

Working with Topology
What Is a Target Device in Topology Discovery?
A device target acts as a seed device in initiating a topology discovery. Junos Space
searches for all the devices and subnets that are connected to the specified device. You
can specify either the hostname or IP address of the device target. You can also use a
range of IP addresses or an IP subnet to initiate the topology discovery.

Devices running the worldwide version of Junos OS use the Telnet protocol instead of
the Secure Shell protocol (SSHv2) 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.

What Steps Do I Need to Take When One of the High Availability Nodes in the Cluster
Shows the Status “Down”?
The first step is to collect all the logs from the cluster as you will want these logs for
troubleshooting later on. Navigate to the Network Management Platform > Administration
> Space Troubleshooting workspace to download troubleshooting data and logs from
the cluster. Then try to log in to the console of the appliance that is down. If you are able
to log in, access the debug shell and check to see whether the jmp-watchdog and jboss
services are up. If the services are not up, do a restart on them and wait 15 to 20 minutes
to see if the node status changes to “Up”. If not, perform a reboot. Once these services
are up, navigate to the Network Management Platform > Administration > Fabric workspace
to add the appliance back to the cluster. If the node does not come up, perform a reboot
and wait 15 to 20 minutes for the node status to change to “Up” in the Network
Management Platform > Administration > Fabric workspace.
If you are unable to log in to the console, or a reboot does not solve the issue, navigate
to the Network Management Platform > Administration > Fabric workspace and delete
the node from the cluster. You can then promote another node (if available) as an HA
node.
You can then try to re image the appliance from a USB stick that has the same version
of Junos Space that is currently running on the other nodes in the cluster. If you are unable
to re-image the appliance, you must get a replacement appliance and re image it.
Copyright © 2015, Juniper Networks, Inc.
27
Junos Space Frequently Asked Questions
NOTE: Whether you re-image the existing appliance or get a replacement
appliance, you must reconfigure the appliance with exactly the same network
settings that were configured previously.
Once the appliance is configured, navigate to the Network Management Platform >
Administration > Fabric workspace to add the appliance back to the cluster.
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
(Ibmethod=byrequests), which provides a weighted round-robin algorithm. However,
because all nodes in the cluster have the same weight, 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 Network Management
Platform User Interface Session?
Open you browser’s dialog, which lists all the stored cookies, then find the site with the
VIP address of the Junos Space cluster and expand it. The content of the cookie named
JSESSIONID contains the hostname of the node which is serving your current session.
How Do I Determine Which Device Connections Are Being Handled by a Node?
The easiest way is to SSH to the console of the node and use the netstat command, as
shown in Figure 1 on page 28. The output will show one line for each device connected
to this node. In this example, the node includes two device initiated connections and five
space initiated connections. The IP addresses of the devices are displayed in the fifth
column.
Figure 1: Using the netstat Command to SSH to the Console of 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.
28
Log in to the console of the node and enter “service heartbeat stop”.
Copyright © 2015, Juniper Networks, Inc.
Chapter 10: High Availability
The heartbeat service on this node will shut down, at which point a message is
automatically sent to its peer node. The peer node will take over the VIP in response
to this message.
2. You can monitor the /var/log/messages file on both nodes to view the log entries
related to the failover.
As the messages will show, VIP failover is almost instantaneous in this case.
