Connecting an x86 Server to the Network
For minimum hardware requirements, see Installation Prerequisites.
To establish basic TCP connectivity to the network, you must connect your x86 64-bit network appliance (running the CSD-Topology software) directly to a switch or router.
Before configuring the x86 server to connect to the network, download and install the RPM bundle as described in Installing the CSD-Topology Software Using the RPM Bundle.
After installing the RPM bundle, the following default settings apply:
host management:internal network=172.16.16.1/24
The Path Computation Server (PCS) runs native on the host machine, and the host address is the PCS.
The following default values are also configured for the JunosVM configuration:
JunosVM internal IP address: 172.16.16.2
JunosVM internal netmask: 255.255.255.0
The JunosVM internal IP and netmask should not be changed.
For network security, by default, JunosVM SSH and telnet access is restricted and available only from the host server (PCS server) using the 172.16.16.2 IP address. To remove this restriction, you can manually remove the firewall filter on the JunosVM lo0 (loopback) configuration.
Figure 1 shows the default interfaces and preconfigured addresses on the x86 appliance.
To establish basic connectivity between the x86 network appliance and a switch or router:
- Power on the x86 network appliance.
- Use one of the following options to access the x86 console:
Use a serial cable to connect to the serial console.
You can use an SSH client (hypertem, minicom, or securecrt) to connect to the serial console.
To set up the serial port connection, refer to your hardware manual.
The serial port setting should be
9600-8-N-1with hardware control enabled.
If your network appliance has two or more Ethernet ports, use an Ethernet cable to connect to the x86 appliance management interface.
Connect an Ethernet cable from a laptop computer to 1-Gigabit Ethernet port 1 on the x86 appliance.
Configure the IP address on your laptop to 172.16.17.10/24.
Using an SSH client, connect to the x86 appliance at IP address 172.16.17.1.
- On the network appliance, connect a 1-Gigabit Ethernet
or 10-Gigabit Ethernet port to the LAN switch or router that you will
use to access the network.
The Ethernet interface on the switch or router must be configured in
- From prompt, log in to the x86 system with the username root and password password.
- To configure the required network settings, access the
Main Menu:[root@csd-topo ~]# /opt/csd-topology/utils/net_setup.py
The Main Menu, shown in Figure 2, displays the options that you can select to configure the host and JunosVM settings, verify network settings, perform maintenance and troubleshooting, and collect trace and log files.
To establish connectivity between the x86 network appliance and a switch or router, the host IP and JunosVM IP addresses (including netmask and default gateway) must be from the same subnet.
To create the host configuration:
You must provide settings for the host external IP address, host external netmask, and host default gateway. All other host settings are optional.
Type A at the prompt and press Enter to update the host configuration.
The current CSD-Topology host configuration settings are displayed.
For each host setting you want to configure, enter the number that corresponds to the specific host parameter (host external IP address, host external netmask, host management IP address, host default gateway, and so forth), and enter the appropriate value.
After you configure the required host settings, type B to apply the host settings.
To create the JunosVM configuration:
You must provide settings for the JunosVM external IP address, JunosVM external netmask, JunosVM default gateway, and BGP AS number. All other JunosVM settings are optional.
Type B at the prompt and press Enter to update the CSD-Topology JunosVM configuration.
The current JunosVM configuration settings are displayed.
For each JunosVM setting you want to configure, enter the number that corresponds to the specific JunosVM parameter (JunosVM external IP address, JunosVM external netmask, JunosVM management IP address, JunosVM default gateway, and BGP AS number), and enter the appropriate value.
After configuring the required JunosVM settings, type C to apply the JunosVM settings.
Verify the host and JunosVM configurations and deploy.
- Type C at the prompt and press Enter to view all current host configuration and JunosVM configuration settings.
- To apply all updated host and JunosVM configuration settings to the CSD-Topology, type Y and press Enter.
