Creating a Connection Profile
You use a connection profile to specify connectivity-related parameters for devices added to Junos Space Network Management Platform using the Modeling devices feature. A connection profile contains device interface details, and the protocol used to assign IP addresses to devices. If you choose to use a NAT server between managed devices and Junos Space Platform, the connection profile uses the NAT configuration configured in the Administration workspace. You create connection profiles from the Connection Profiles page in the Devices workspace.
To create a connection profile:
- On the Network Management Platform user interface, select Devices > Model Devices > Connection Profiles.
The Connection Profiles page is displayed.
- Click the Create Connection Profile icon on the Actions
menu.
The Create Connection Profile page is displayed.
- In the Name field, enter a name for the new connection
profile.
The connection profile name cannot exceed 255 characters and can contain letters, numbers, spaces, and special characters. The special characters allowed are period (.), hyphen (-), and underscore (_). The connection profile name cannot start with letters or numbers and cannot contain leading or trailing spaces.
- (Optional) In the Description field, enter a description
for the new connection profile.
The description cannot exceed 256 characters.
- Select the type of device interface on which you want
to configure the IP address: Ethernet, ADSL,
or T1.
By default, the Ethernet option button is selected.
- (Optional) In the Interface field, enter the appropriate
device interface number.
The default Ethernet interface number is ge-0/0/0. The default ADSL interface number is at-1/0/0.
- Select the format of the IP address for the devices to
be modeled using this connection profile. By default, the IPv4 option button is selected.
If you want to model devices by using an IPv6 address, select the IPv6 option button.
Note:The contents of the configlet generated differ based on the format of the IP address.
- (Optional) Select the NAT'd IP Address for Junos
Space check box to use the NAT configuration specified in the
Administration workspace.
By default, this check box is cleared. If you are not using a NAT server or have disabled or not enabled the NAT configuration, this field is dimmed.
Note:You need to configure the NAT server with the same format of the IP address that you chose to model devices by using this connection profile.
Refer to http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xhtml for the list of restricted IPv4 addresses and http://www.iana.org/assignments/ipv6-address-space/ipv6-address-space.xhtml for the list of restricted IPv6 addresses.
- (Optional) From the IP Assignment via drop-down
list, select how the IP address is assigned to the devices. By default,
DHCP is selected. The options presented hereafter depend on the type
of device interface on which you configure the IP address and how
the IP address is assigned to the devices.
You can assign IP addresses by using the following options for Ethernet and T1 interface:
Manually (Static)
Dynamic Host Configuration Protocol (DHCP)
Point-to-Point Protocol over Ethernet (PPPoE)
You can assign IP addresses by using the following options for the ADSL interface:
Manually (Static)
Dynamic Host Configuration Protocol (DHCP)
Point-to-Point Protocol over ATM (PPPoA)
If you want to assign an IP address to the device manually:
Select Static from the IP Assignment via drop-down list
If you select Static, you should enter the IP addresses of the devices manually when you create a modeled instance.
If you select DHCP from the drop-down list:
From the Attempts selector, use the up and down arrows to specify the maximum number of attempts that the DHCP server will make to reconfigure the DHCP clients before the reconfiguration is considered to have failed.
The default value is 4 attempts.
From the Interval selector, use the up and down arrows to specify the initial value in seconds between successive attempts to reconfigure the DHCP clients.
The default value is 4 seconds.
(Optional) Select the DHCP Server Address check box to configure the properties of the DHCP server.
In the IP Address field, enter the IP address of the DHCP server.
Note:You can enter the IP address in either IPv4 or IPv6 format.
If you want the DHCP clients to propagate the TCP/IP settings to the DHCP server, select the Update Server check box.
Select one of the option buttons in the Lease Time section: Default Value, Lease Never Expires, or Lease time. By default, the Default Value option button is selected.
This option specifies the time taken by the DHCP server to negotiate and exchange DHCP messages with the DHCP clients.
If you want the DHCP server to negotiate and exchange DHCP messages with the DHCP clients, select the Default Value option button.
If you want the DHCP server to assign permanent IP addresses, select the Lease Never Expires option button.
If you want to specify a time interval after which the lease expires, select the Lease Time option button and use the up and down arrows in the Interval selector to specify the time interval.
The default value is 4 seconds.
If you select PPPoE from the drop-down list:
From the Authentication Type drop-down list, select the type of authentication.
Junos Space Network Management Platform supports Challenge Handshake Authentication Protocol (CHAP) and Password Authentication Protocol (PAP) for authentication.
In the Username field, enter the username for PPPoE authentication using CHAP.
In the Password field, enter the password for PPPoE authentication using CHAP.
In the Confirm Password field, reenter the password for PPPoE authentication using CHAP.
In the Access Profile Username field, enter the username for PPPoE authentication.
This field is not mandatory for PAP authentication.
In the Access Profile Password field, enter the password for PPPoE authentication.
This field is not mandatory for PAP authentication.
In the Access Profile Confirm Password field, reenter the password for PPPoE authentication.
This field is not mandatory for PAP authentication.
(Optional) In the Concentrator Name field, enter the name of the concentrator.
(Optional) In the Service Name field, enter the name of the service you are using.
In the Auto Connect time Interval field, use the up and down arrows to specify the time interval in seconds for connecting automatically. The default value is 1 second.
In the Ideal time before disconnect field, use the up and down arrows to specify the time interval in seconds before disconnecting. The default value is 1 second.
If you select PPPoA from the drop-down list:
From the Authentication Type drop-down list, select the type of authentication.
Junos Space Network Management Platform supports Challenge Handshake Authentication Protocol (CHAP) and Password Authentication Protocol (PAP) for authentication.
In the Username field, enter the username for PPPoE authentication using CHAP.
In the Password field, enter the password for PPPoE authentication using CHAP.
In the Confirm Password field, reenter the password for PPPoE authentication using CHAP.
In the Access Profile Username field, enter the username for PPPoE authentication.
This field is not mandatory for PAP authentication.
In the Access Profile Password field, enter the password for PPPoE authentication.
This field is not mandatory for PAP authentication.
In the Access Profile Confirm Password field, reenter the password for PPPoE authentication.
This field is not mandatory for PAP authentication.
In the VPI field, use the up and down arrows to specify the Virtual Private Identifier (VPI) for the DSL network of your service provider. The range is 1 to 6000. The default value is 1.
In the VCI field, use the up and down arrows to specify the Virtual Channel Identifier (VCI) for the DSL network of your service provider. The range is 1 to 6000. The default value is 1.
From the Encapsulation Type drop-down list, select the type of encapsulation: atm-ppp-vc-mux or atm-ppp-llc. atm-ppp-vc-mux provides PPP over ATM AAL5 multiplex encapsulation and atm-ppp-llc provides PPP over AAL5 LLC encapsulation.
