Page 25: User Table
User Table This table contains authentication and configuration information for five types of users: Login, Network, Callback, Dial-out, and Manage. Login Network Callback Dial-out Manage User table entries override settings for the interface to which the user is connected. Local and Login Hosts The Local Hosts Table contains a list of local hosts and associated Internet Tables Protocol (IP) addresses.
Page 26: Facility Level Table
1: R HAPTER OUTER ONFIGURATION Facility Level Table This table is used to configure the log level of all facilities (software systems) on the RAS 1500. It contains each event facility and its associated log level. Each facility generates unique event messages during processing that can be sent to a SYSLOG server you define as a means of judging system performance.
Page 27: Snmp Configuration Tables
SNMP Configuration The RAS 1500 provides support for SNMP version 1 and industry standard Tables MIB-II variables. These variables are fully described in your MIB-II documentation. The SNMP Community Table stores information about which SNMP servers (if any) are permitted to make SET and GET requests, as well as Read and Write Communities.

Page 50: Network Address Formats
3: R HAPTER OUTER OMMAND Configuration changes are impermanent: they occur immediately but are lost on reboot unless you save them because the save all command places configuration changes in FLASH memory. These changes are lost by the SuperStack II Remote Access System (RAS) 1500, if power fails before saving them.
Page 51: Interface Ranges
mac_ address ipx_host address Interface Ranges Interfaces can be expressed as variants of the x/slot:y/mod:z format, where x is the unit type (either rm0 for the RAS 1500 base unit, pau0 for the Primary rate Access Unit (PAU), or pem0 or pem1 for the RAS 1500 Expansion unit), y is the slot number (the PAU always uses slot:1), and z is a modem number.
Page 52: Users
3: R HAPTER OUTER OMMAND Users A user entity is a table of parameters that are used when establishing a network connection. The add user and set user commands define the parameters of a user.

4: R HAPTER OUTER OMMAND initialization script to a switched interface, that string is sent to the serial line driver whenever a connection terminates, to ready the modem for the next connection. You need not assign init scripts to modems. The maximum is 32 initialization scripts.

Page 63: Add Ip Pool
Parameter <network_name> address frame interface enabled add ip pool initial_pool_address <IP_network_address/subnet> <pool_name> route [aggregate | no_aggregate] size <1-4096> state [public | private] Assigns a specified number of contiguous IP addresses for allocation by the RAS 1500. When dial-in network users are dynamically assigned IP addresses, those IP addresses are allocated from a pool which has the advantage of bundling several IP addresses into one to limit RIP advertisements.

Page 64: Add Ip Route
4: R HAPTER OUTER OMMAND The RAS 1500 automatically derives subnet masks for aggregate users but a mask can be configured for no_aggregate users. Users assigned to more than one pool receive an address from the last assigned pool in round robin fashion. Also, if the administrator reduces the size of the pool, users whose associated address pool was deleted wont be denied access until after their calls have terminated.

Page 65: Add Ip Udp_Bcast
Static routes are installed but not visible via the list ip routes command until the interface to the gateway is active (entered in the Forwarding Table). Parameter <network_ address> gateway metric add ip udp_bcast_ add ip udp_bcast_forwarding_port <port> forwarding_port Identifies the source port number from which User Datagram Protocol (UDP) packets on the private network are forwarded by the RAS 1500.

4: R HAPTER OUTER OMMAND Parameter <network_name> address interface enabled frame add ipx route gateway [ipx_host_address] <ipx_network_ metric [1-15] address> ticks [tick_number] Adds an IPX static route to the system IPX Route Table, which defines static routes to remote IPX networks. The command list ipx routes displays currently defined static routes.

Page 67 indicate the next router hop. To remove this service, use the delete ipx service command. See the show IPX settings command for more information. Parameter Description <service name> Designation of IPX service. Limit: 32 ASCII characters. address Internal network number for the IPX service on which this service resides.
Page 68: Add Login_Host
4: R HAPTER OUTER OMMAND add login_host address [IP_address] <host_name> preference [number] rlogin_port [TCP_port_number] telnet_port [TCP_port_number] clearTCP_port [TCP_port_number] Adds up to ten login hosts to the Login Host Table. You add login hosts so users of type login connecting to an IP host can reference the host by name.

Page 69: Add Nat Dynamic User
The default modem group, “all,” cannot be modified. Parameter <group_name > interfaces Example: add modem_group dialout interfaces rm0/slot:1/mod:[1-4],pem0/slot:1/mod:1 add nat dynamic user count <number of addresses> <user_name> public_pool_start<ip_address> Configures, and associates a name with, a specific number of ISP-assigned addresses for Dynamic Network Address Translation (NAT) by the RAS 1500.

Page 70: Add Nat Static User
4: R HAPTER OUTER OMMAND addresses that you configured by using this command. The RAS 1500 maintains a table of active IP addresses on the public network mapped to user IP addresses on the private network for the connection. Once the connection to the public network is closed, the information in the table is dropped and this IP address is free for the next connection.

Page 71: Add Network Service
Each time the IP address on the private network, “1.1.1.1” connects to the public network, Static NAT translates the IP address and connects it to the static assigned addresses, “2.2.2.2”. The RAS 1500 maintains a table of active mappings between IP addresses on the private network mapped to statically assigned IP addresses on the public network.

Page 72 4: R HAPTER OUTER OMMAND Parameter <service_name> close_active_ connections data enabled server_type socket The next table shows configurable parameters for network service, which are specified with the data value. EFERENCE Description Name of this type of service. Limit: 64 ASCII characters. Indicates whether to close any active connections when a service is disabled by the disable network_service command.

Page 241 TThis chapter contains the following information: IP Addressing Basics Administrators generally use three address classes in IP, with address ranges as follows: Class A - 0-127; Class B - 128 - 191; and Class C - 192 - 248. IP addresses are 32 bits long and generally written in dotted decimal notation: four decimal values separated by periods, followed by a forward slash and the associated subnet mask.
Page 242: Subnetting
C: A PPENDIX DRESSING CHEMES In the figure below, notice that the position of this line is determined by the position of the first zero bit in the address. Figure 1 Address Class Map Subnetting A large IP network can be subdivided into smaller subnetworks. This is done using a subnet mask (in this text, often called netmask), which tells a routing device how to further subdivide the Host ID portion of an IP address.

IP Subnet Mask Subnet masking is used to expand the number of networks due to the Address Table 32-bit limitation of the IP address field. When assigned an address by the NIC, the address can be further broken down to expand the single net number to many more by using host bits.
