Modem Administration

This section describes how to set up a point-to-point protocol (PPP) link between the Netra server and a remote host using a modem.

PPP enables two computers to be connected over a two-way communications link. The connection is established as needed. Using the Netra j interface, you can administer connections to a remote host system (for example, your ISP) using PPP. The following PPP protocol options are supported:

Connecting to a Remote Host Using a Modem

To connect to a remote host using a modem and PPP do the following general tasks:

  1. Define a modem.

    Examine the existing modem definitions in the Netra server using the View modem definitions option described on "To View Modem Definitions". If an initialization definition for your modem has already been created, skip this task. If not, add an initialization definition and a unique name for your modem using the Add a modem definition option described on "To Add a Modem Definition".

  2. Assign the modem to a port.

    Your modem must be physically connected to the Netra server on one of the serial ports. Assign your modem to a specific port by using "Modem Port Assignments".

  3. Add a remote host connection.

    After you assign a modem to a serial port, set up a connection to a remote host using "Connecting to a Remote Host Using a Modem". (Note that this option is not displayed until at least one modem is assigned to a port.)

Routing Administration

This section describes how to configure the Netra server as a router.

Routing is the mechanism by which systems on different networks can communicate with each other. Each network usually has at least one system called a router. A router is a system that is connected to multiple networks; it maintains information that defines routes between host systems and networks.

The Netra system can be configured as one of the following:

Dynamic Router

A dynamic router relies on information broadcast from other routers to update its routes and reflect changes in the network topology. It also broadcasts this information to other dynamic routers.

Dynamic routers are typically required when systems act as gateways between networks or within large networks where route information is constantly changing. The Netra server supports the following dynamic routing protocols:

If client host systems are required to use the dynamic router, they must either run programs that can communicate using these protocols, or they must specify the dynamic router as a default router.

When the Netra server is configured as a dynamic router, broadcasting RIP information over point-to-point (PPP) links can be enabled or disabled. If additional PPP links are defined after the dynamic router is configured, you must reconfigure the dynamic router to ensure that it is aware of the new links.

To Configure the Netra System as a Dynamic Router

  1. From the Main Administration page, under "Network Connection Administration," click Routing.

    The Routing Administration page is displayed.

  2. Click Configure dynamic router.

    The Dynamic Router Administration page is displayed.

  3. Complete the form using the information in the following table.

    Table 7-6 Dynamic Router Administration

    Option 

    Description 

    Host/Net 

    Specify if a destination address is a Network or a Host. If a value of "net" is entered incorrectly, the system attempts to add the routing entry as a "host." 

    Destination Address  

    Network/Host address to which information is routed. 

    Gateway Host Address 

    Host address of the gateway used for accessing the destination address. If the router is unreachable when this form is configured, it is not used for routing until dynamic routing is reconfigured or the Netra system is restarted. 

    Hop Count 

    A value of 0 or greater. 0 means the Netra server is the router; a value greater than 0 means that another system is the router. 

    Status 

    Active or Passive. Gateways marked "active" are removed from the routing information if they become inaccessible. Gateways marked "passive" are part of the routing information until explicitly removed. Routes to passive gateways are also not broadcast to the other systems on the network.  

    Dynamic Routing Information over Point-to-Point Links 

    Enables or disables RIP over PPP links. Choices: Yes or No. 

  4. Click OK.

To Modify a Dynamic Router

  1. From the Main Administration page, under "Network Connection Administration," click Routing.

    The Routing Administration page is displayed.

  2. Click Modify dynamic router.

  3. Complete the form using the information in Table 7-6.

Static Router

A static router relies on the manual addition of routes. Routing information is not exchanged with other routers.

Static routers are typically used in very stable, simple networks. An example of such a network would be a single LAN connected to the Internet or to another network over a PPP link.

If machines on the LAN require a static router, it must be specified as a default router.

To Configure the Netra System as a Static Router
Note -

Before using static routing over PPP links, configure a PPP connection to the remote host using "Modem Administration", and add a static route to the remote host's host address (IP address).

  1. From the Main Administration page, under "Network Connection Administration," click Routing.

    The Routing Administration page is displayed.

  2. Click Configure static router.

    The Static Router Administration page is displayed.

  3. Complete the form using the information in the following table.

    Table 7-7 Static Router Administration

    Option 

    Description 

    Default Router Host Address  

    Host address of the default router for the network. 

    Host/Net 

    Specify whether a destination address is a Network or a Host. If a value of "net" is entered incorrectly, the system attempts to add the routing entry as a "host." 

    Destination Address 

    Network/Host address to which information is routed. 

    Router Host Address 

    Host address of the router used for accessing the destination address.  

    Hop Count 

    A value of 0 or greater. 0 means the Netra server is the router; a value greater than 0 means that another system is the router. 

Note -

If a host address is unreachable at the time of configuration, it is accepted with a warning that the route cannot be accessed. To activate the route once it can be accessed, restart the Netra System, or reconfigure he static router.

To Modify a Static Router

  1. From the Main Administration page, under "Network Connection Administration," click Routing.

    The Routing Administration page is displayed.

  2. Click Modify static router.

  3. Complete the form using the information in Table 7-7.

Setting a Default Route Over a PPP Link

If you require a default route over a PPP link, choose one of the following options:

If both the local and the remote host addresses are dynamically assigned, you cannot use a default route over a PPP link.

Not a Router

A non-gateway system need not be a router in networks that already have dynamic routers. The Netra server listens for dynamic routers to broadcast route information using the RIP and the ICMP router discovery protocols.

To Configure the Netra System as Not a Router
Note -

Once the Netra server is already configured as "not a router," this option is not displayed.

  1. From the Main Administration page, under "Network Connection Administration," click Routing.

    The Routing Administration page is displayed.

  2. Click Turn off routing, then confirm the operation.

ATM Administration

This section describes how to set up a connection to an asynchronous transfer mode (ATM) network.

Note -

This option is displayed on the Main Administration page only if the relevant hardware and software has been installed. (See system's hardware installation manual for instructions on adding network interface hardware. See Netra System Administration for software installation instructions.)

ATM Requirements

ATM is a connection-oriented network protocol. To use this protocol, two communicating entities must establish a connection before data transfer can begin. The Transport Control Protocol/Interface Program (TCP/IP), on the other hand, is inherently connectionless.

The SunATM(TM) 2.1 software supports two protocols that reconcile the differences between the ATM and TCP/IP paradigms:

Both these protocols enable TCP/IP to run transparently over an ATM interface by resolving an IP address to an ATM address and establishing the connection to the host to which a message is addressed.

The Netra ATM administration module supports SunATM version 2.1 software and SunATM-155 version 2.1 hardware. (The SunATM-155/Mfiber SBus Adapter 2.1 and SunATM-155/UTP5 SBus Adapter 2.1 are single-wide SBus adapters that conform to the specifications of the ATM Forum.)

Classical Internet Protocol Interface

Classical IP supports the TCP/IP and the User Datagram Protocol/Interface Program (UDP/IP) protocols in an ATM environment. An ATM address resolution protocol (ATM ARP) server replaces the traditional ARP protocol by resolving IP addresses to ATM addresses. It is accessible to all hosts on a subnet. Each host must register with the ARP server when the ATM interface is brought up.

Classical IP has the following limitations because it does not support broadcast and multicast messaging.

Each ATM port (SBus card) on the Netra server supports only one Classical IP interface.

LAN Emulation Interface

LAN Emulation, which provides mechanisms to send broadcast messages, is another way of supporting the TCP/IP and UDP/IP protocols over an ATM network. A series of LAN Emulation services (such as the LAN Emulation Configuration Server -LECS-, the LAN Emulation Server -LES-, and the Broadcast and Unknown Server -BUS-) provide address resolution information. When a LAN Emulation interface is brought up, it joins the LAN by registering with these services. The LAN Emulation protocol provides a broadcast service to the upper layer protocols. Therefore, a LAN Emulation interface is not affected by the multicast and RIP limitations of Classical IP.

Each ATM port on the Netra server currently supports only one LAN Emulation interface.

Configuring ATM Interfaces

To configure ATM interfaces on the Netra server, you must perform the following general tasks:

  1. Set the type of framing interface.

    ATM switches use either the Synchronous Digital Hierarchy (SDH) or the Synchronous Optical NETwork (SONET) framing interface. (The framing interface used by the ATM switch should be in the switch product information.) Set the framing interface type using the Change Framing Interface option, as described on "Framing Interface".

  2. Set the User Network Interface (UNI) version for each ATM port.

    Each ATM port must be configured with a User Network Interface version. This version applies to all Classical IP and LAN Emulation interfaces configured on that port. Each port can be configured with a different version. Set the UNI version using the Change User Network Interface Version option, as described on "User Network Interface ".

  3. Configure a Classical IP and/or a LAN Emulation interface for each ATM port.

    Use the Configure a Classical IP Interface and Configure a LAN Emulation Interface options described on "Classical IP Interface " and "Configuring a LAN Emulation Interface ".
