Device Profile

 

Navigate to Administration>Device Profile to open the Device Profile window where you can:

  • Set up or modify the device list. Initially, the device list contains all the devices discovered from the TED. The device IP address (if not already discovered) and the PCEP IP address for each device are required. The PCEP IP address is the local address of the PCC located in the PCE statement stanza block.

  • Supply a hostname for each router for OSPF networks. This is necessary because the TED does not contain hostnames for OSPF networks.

  • Specify an MD5 key to secure PCEP communication between the NorthStar Controller and the PCC.

  • Specify device SNMP parameters for SNMP connectivity.

  • Test connectivity of devices using ping, SSH, and SNMP.

Figure 1 shows the Device Profile window.

Figure 1: Device Profile Window
Device Profile Window

The Device Profile window consists of the following panes:

  1. Device List (upper pane)—Lists all the devices that are part of the profile selected in the profile names list.

  2. Device Detail (lower pane)—Displays detailed information about the device selected in the device list.

Device List Pane

The Device List pane shows all the devices in the profile along with many of their properties. You can change the order of the devices in the list by clicking and dragging rows. Sorting, column selection, and filtering options are available when you hover over a column heading and click the down arrow that appears. Figure 2 shows these options.

Table 2 describes the data entry fields under the Access Parameters tab.

Table 2: Add New Device Access Field Descriptions

Field

Description

Autofill device from the selected profile entry

Select a device on which to model the new device using the drop-down menu. The properties of the selected device populate the new device window. You can modify the imported fields.

Device Name

Name of the network device, which should be identical to the hostname. During configuration collection, the software uses this name as part of the name of the collected configuration file. The configuration filename uses the format ip.name.cfg. If the device name is left blank, the configuration filename uses the format ip.cfg.

Device IP

Required field: IP address of the network device.

Management IP

Management IP address for the device. NorthStar Controller first attempts connection using the management IP address if it is specified, and then the IP address.

Note: The management IP address is required for out-of-band management access.

Vendor (Type)

Select the device vendor from the drop-down menu. The default is GENERIC. The vendor is displayed in the Device List under the column heading Type.

Model

Model number of the device.

OS

Type of operating system installed on the device.

OS Version

Version number of the operating system build installed on the network device. The default value is > 14.2x.

Note: For routers configured with PCEP using Junos OS Release 14.2x and earlier, select <= 14.2x for this parameter.

SSH Timeout

Number of milliseconds after which a connection attempt times out. The default is 300. To enter a different value, type the number of milliseconds in the field or use the up and down arrows to increment or decrement the displayed value.

SSH Retry

Number of times a connection to the device is attempted. The default is 3. To enter a different value, type the number of retries in the field.

SSH Command

Command to use for SSH connection. The default is ssh. To enter a different value, type the command in the field. Include the full path of the command and options used for ssh, such as /usr/bin/ssh -1 -p 8888.

Enable Netconf

Select this checkbox to enable Netconf communication to the device.

Netconf Retry

Enter the number of times a Netconf connection is to be attempted. The default is three.

Note: A value of 0 means an unlimited number of retries - connection attempts never stop.

PCEP IP

The local address of the PCC located in the PCE statement stanza block.

Note: We highly recommend that this field be populated.

PCEP MD5 String

Message Digest 5 Algorithm (MD5) key string, also configured on the router. Configuring MD5 provides information on configuring MD5 authentication.

Note: All the routers in the network must have their PCEP IP addresses in the profile. This is especially important if any router in the network is configured with an MD5 authentication key.

Login

Login ID for the network device.

Password

Password for the network device.

Privilege Login

Login ID for situations that require a higher-security login.

Privilege Password

Password for situations that require a higher-security login.

The fields on the SNMP Parameters tab are required to set up for SNMP collection. The SNMP parameters are described in Table 3.

Table 3: SNMP Parameters

SNMP Parameter

Description

SNMP Version

Use the drop-down menu to select SNMPv1, SNMPv2c, or SNMPv3. The default is SNMPv2c.

SNMP Port

SNMP port. The default is 161. Must match the port configured on the router.

Click Submit to complete the device addition. The new device appears in the device list.

Modify Device

The Modify button opens the Modify Device window, which has the same fields as the Add New Device window. Edit the fields you want to change and click Submit. Click the Save button (disk icon) to complete the modification. You can wait until you have completed all your device modifications to click the Save button, which will have turned red to indicate there are unsaved changes.

To modify one or more fields in the same way for multiple devices, Ctrl-click or Shift-click to select the devices in the device list and click the Modify (pencil) button. On the resulting Modify Device(s) window, you can make changes that affect all the selected devices.

Note

As an alternative to opening the Modify Device window, you can change some of the device properties directly in the Device List pane by double-clicking the fields.

Delete Device

To delete a device, select the device row in the Device List and click the Delete button. A confirmation window is displayed as shown in Figure 7.

Click Yes to complete the deletion.

Figure 7: Delete Device Confirmation Window

Click Browse to specify the CSV file that contains the devices to be added, and indicate the appropriate delimiter by selecting the corresponding radio button. A preview of the data appears in the Data Preview box.

Click Import to complete the import. The imported devices appear in the device list.

Device Detail Pane

The Device Detail pane displays the properties of the device that is highlighted in the Device List pane. There are two ways to minimize this pane:

  • Click the down arrow at the top center of the pane. Click the up arrow to maximize the pane.

  • Click the down arrow in the top right corner of the pane. Click the up arrow to maximize the pane.

Click and drag the top margin of the pane to resize the pane.

Configuring MD5

MD5 can be used to secure PCEP sessions as described in RFC 5440, Path Computation Element (PCE) Communication Protocol (PCEP). MD5 authentication must be configured on both the NorthStar Controller (in the Device Profile window) and on the router (using the Junos OS CLI). The authentication key must be the same in both configurations. The device profile acts as a “white list” when MD5 is configured. The NorthStar Controller does not report LSPs or provision LSPs for the routers not included in the device profile.

Note

The first time MD5 is enabled on the router, all PCEP sessions to routers are reset to apply MD5 at the system level. Whenever the MD5 enabled status on a router or the MD5 key changes, that router resets the PCEP connection to the NorthStar Controller.

In the NorthStar Controller Device Profile window, perform the following steps to configure MD5 for the PCEP session to a router.

  1. Select a router in the Device List pane.
  2. Click to open the Modify Device(s) window.
  3. In the MD5 String field, enter the MD5 key string. Click Modify.
  4. Click to save your changes. The PCEP MD5 Configured field for the router changes from no to yes.Note

    All the routers in the network must have their PCEP IP addresses in the profile. When you save your changes, you might receive a warning, reminding you of this.

In the Junos OS CLI on the router, perform the following step to configure MD5 for the PCEP session to the NorthStar Controller.

  1. Use the set authentication-key command at the [edit protocols pcep pce] hierarchy level to configure the MD5 authentication key.
