Configuring Basic Settings
Before you begin initial configuration, complete the following tasks:
- Install the routing platform in its permanent location, as described in the hardware installation guide or the Getting Started Guide for your routing platform.
- Gather the following information:
- Hostname for the router on the network
- Domain that the router belongs to on the network
- Password for the root user
- Time zone where the router is located
- IP address of a Network Time Protocol (NTP) server (if NTP is used to set the time on the router)
- IP address of a Domain Name System (DNS) server
- List of domains that can be appended to hostnames for DNS resolution
- IP address of the default gateway
- IP address to be used for the loopback interface
- IP address of the built-in Ethernet interface that you will use for management purposes
- Collect the following equipment:
- A management device, such as a laptop, with an Ethernet port
- An Ethernet cable
To configure basic settings with J-Web Initial Configuration:
- Enter information into the Initial Configuration Set Up page (see Figure 1), as described in Table 1.
- Click Apply to apply the configuration.
Figure 1: J-Web Set Up Initial Configuration Page
Note: For J Series routers only, after initial configuration is complete, the routing platform stops functioning as a Dynamic Host Configuration Protocol (DHCP) server. If you change the IP address of the management interface and have the management device configured to use DHCP, you lose your DHCP lease and your connection to the routing platform through the J-Web interface. To reestablish a connection, either set the IP address on the management device manually, or connect the management interface to the management network and access the routing platform another way—for example, through the console port.
Table 1: Initial Configuration Set Up Summary
Field | Function | Your Action |
|---|---|---|
| Identification | ||
Host Name (required) | Defines the hostname of the router. | Type the hostname. |
Domain Name | Defines the network or subnetwork that the machine belongs to. | Type the domain name. |
Root Password (required) | Sets the root password that the user “root” can use to log in to the router. | Type a plain-text password that the system encrypts. Note: After a root password has been defined, it is required when you log in to the J-Web user interface or the CLI. |
Verify Root Password (required) | Verifies that the root password has been typed correctly. | Retype the password. |
| Time | ||
Time Zone | Identifies the time zone that the router is located in. | From the list, select the appropriate time zone. |
NTP Servers | Specify an NTP server that the router can reach to synchronize the system time. | To add an IP address, type it in the box to the left of the Add button, then click Add. To delete an IP address, click it in the box above the Add button, then click Delete. |
Current System Time | Synchronizes the system time with the NTP server, or manually sets the system time and date. |
|
| Network | ||
DNS Name Servers | Specify a DNS server that the router can use to resolve hostnames into addresses. | To add an IP address, type it in the box to the left of the Add button, then click Add. To delete an IP address, click it in the box above the Add button, then click Delete. |
Domain Search | Adds each domain name that the router is included in to the configuration so that they are included in a DNS search. | To add a domain name, type it in the box to the left of the Add button, then click Add. To delete a domain name, click it in the box above the Add button, then click Delete. |
Default Gateway | Defines a default gateway through which to direct packets addressed to networks not explicitly listed in the routing table. | Type a 32-bit IP address, in dotted decimal notation. |
Loopback Address | Defines a reserved IP address that is always available on the router. If no address is entered, this address is set to 127.0.0.1/32. | Type a 32-bit IP address and prefix length, in dotted decimal notation. |
fe-0/0/0 Address (on J2300, J4300, and J6300 routers) ge-0/0/0 Address (on J4350 and J6350 routers) fxp0 Address (on M Series routers) | Defines the IP address and prefix length of the management interface. The management interface is used for accessing the router. The DHCP client sets this address to 192.168.1.1/24 if no DHCP server is found. | Type a 32-bit IP address and prefix length, in dotted decimal notation. Note: You must enter the address for the management interface on the Quick Configuration Set Up page before you click Apply. If you do not manually configure this address, you will lose your connection to the J-Web interface when you click Apply. |
| Management Access | ||
Allow Telnet Access | Allows remote access to the router by using Telnet. | To enable Telnet access, select the check box. |
Allow JUNOScript protocol over Clear-Text Access | Allows JUNOScript to access the router by using a protocol for sending unencrypted text over a TCP connection. | To enable JUNOScript access over clear text, select the check box. |
Allow SSH Access | Allows remote access to the router by using SSH. | To enable SSH access, select the check box. |
