Plug one end of the serial cable into the maintenance console port on the Cayman 3220-H back panel. 9VDC DSL C ENAN MAINT OLE CONS E To Your Terminal or Terminal Emulator 3. Connect the other end of the serial cable to the serial port on your terminal (or terminal emulator) or the modem port of your computer. 4.
5. Turn on the Cayman 3220-H. The terminal console window will begin displaying startup messages from the Cayman 3220-H. 6. When the console displays STAY IN EPROM?, type Y. The Cayman 3220-H console prompt (BootPROM>) appears, indicating that the Cayman 3220-H is now operating in diagnostic (EPROM) mode. Using the Diagnostic Console You communicate with the diagnostic console via a simple command-line interface.
If a text string includes spaces or tabs, you must enclose the string with double quote marks. Basic Commands The defaults and help commands are especially useful for users not familiar with the diagnostic console. defaults The defaults command sets the EPROM settings in the Cayman 3220-H to their factory default values. After you reset the Cayman 3220-H EPROM values to their defaults, you must save them to non-volatile storage with the save command.
help [command] or command ? The help command displays a summary of the available commands. The help command displays the syntax and function of the command you specify. To access an overview of the diagnostic console commands, type help or ? at the console prompt.To access on-line help for a specific command, type help command or command ? at the console prompt.
clear The clear command clears the current and non-volatile copies of the Cayman 3220-H EPROM settings. Compare the erase options command, which clears the contents of the parameter flash. erase [ code | options | headers ] [yes] The erase command completely erases the specified flash memory area in the Cayman 3220-H. erase code clears the code flash in the Cayman 3220-H. erase options clears the parameter flash (not the EPROM settings).
revert The revert command retrieves the saved version of settings from non-volatile storage and overwrites any changes made since the last save. save The save command saves the EPROM settings you have entered or changed to non-volatile storage in the Cayman 3220-H. show The show command displays the current EPROM settings for the Cayman 3220-H and a brief explanation of those settings.
autoboot sequence tries to load an image from download sources in the following order: 1. If flash is enabled, start an image from the Cayman 3220-H code flash memory, using the configured image number; else 2. If ip is enabled, load an image via IP TFTP using the configured IP server, IP gateway, netmask and filename; else 3. If bootp is enabled, load an image from a BOOTP server on your IP network.
flash off disables downloading from flash (which removes the flash step from the boot and autoboot sequence). ip ip_address The ip ip_address command enables TFTP downloading and specifies the IP address of the Cayman 3220-H in dotted-decimal notation. Enter ip 0 to disable IP TFTP downloading. Changing the IP address of a Cayman 3220-H may result in ARP cache inconsistencies on your IP hosts.

C How Your Cayman 3220-H Works About ATM About Network Address Translation About Bridging and Routing About DHCP About PPP About PPP over Ethernet About ATM Asynchronous Transfer Mode (ATM) is a connection-oriented cell-based transport mechanism that allows very high-speed transfer of data, voice, and video from one point to another.An ATM network consists of a series of switches that connect one end of a virtual circuit to another.
ATM uses fixed-length cells to transport data. When data, such as an Ethernet packet, is passed to ATM, the data is segmented into a series of small (53-byte) cells. Each ATM cell consists of 5 bytes of header information (virtual path identifier, virtual circuit identifier, and CRC checksum) and 48 bytes of data. Information in the header identifies cells belonging to the same virtual channel, which is used to route the cell to its intended destination.
About Bridging and Routing Your Cayman 3220-H device functions as a network router for TCP/IP traffic and as a network bridge for other traffic, such as NetWare, DECnet, or AppleTalk. TCP/IP Routing As a TCP/IP router, your Cayman 3220-H keeps track of the networks that are accessible through each network interface.
addressed to a MAC address that isn't in its bridging table, the Cayman 3220-H relays the packet to all network interfaces other than the one from which it received the packet. If it later receives a reply from the destination host, it adds that host's MAC address and the interface appropriate for reaching that host to its bridging table. The Cayman 3220-H tracks the age of each entry in its bridging table, and deletes entries that aren't used after 10 minutes.
address, the Cayman 3220-H selects another address and repeats the sequence until it finds an address that is not in use. Dynamic allocation of IP addresses means that an IP address can be reused when it is not longer needed by the client to which it is assigned. Dynamic IP address allocation is particularly useful in situations where clients connect to a network temporarily or where a site needs to share a limited pool of IP addresses among a group of clients that do not need permanent IP addresses.
several Network Control Protocols (NCPs), which establish how datagrams for a specific higher-level protocol using PPP as a data link should be encapsulated. Network control protocols establish and configure different network-layer protocols, such as TCP/IP. PPP encapsulation provides for transmission of different network-layer protocols simultaneously over the same link. Once a PPP link is established, a PPP peer can negotiate the exchange of TCP/IP, IPX, or AppleTalk packets over standard telephone lines.
Dial-out -- If a port is configured as a dial-out interface, the router opens a PPP link when an internal Network Protocol routes a packet out the PPP interface. If PPP determines that the serial connection is not open, the router passes a telephone number and modem configuration information to the modem, which calls the modem connected to the remote peer. When the two modems establish a connection, the two peers begin negotiating the link configuration.
proposes new settings acceptable to the second peer. A Configure-Nak message may also include proposed configuration settings for options that the second peer requires but that the first peer did not include in its Configure-Request. Configure-Reject -- If one or more of the configuration options in a Configure-Request are not recognizable or are not acceptable for negotiation, the second peer returns a Configure-Reject message that identifies the rejected options.
The authentication method used by one peer can be different from the authentication method used by the other peer. For example, a peer at one end of a link may require authentication while the other end of the link may not. Similarly, one end of a link may use PAP to authenticate peers while the other end uses CHAP. A PPP interface can support one or both authentication methods.
Network Configuration After a PPP link has been established and authentication has been satisfied, PPP sends Network Control Protocol (NCP) packets to configure one or more network layer protocols, such as TCP/IP. Link Up Once a network-layer protocol is configured, the PPP link is considered up (open), and datagrams for that protocol are exchanged over the link. Either peer can close a network-layer connection without interfering with other network-layer connections or the LCP connection.
network. When the router receives a packet, it consults its routing table to decide where to send the packet. Static and Dynamic Routes Selecting the Most Efficient Route Routes to other networks can be entered and maintained manually (static routes) or acquired from other routers interactively (dynamic routes): Static routes identify pathways to destination networks that are stable over time or to networks that must always be available, even if a link is not currently open.
If the router has a static route and a dynamic route with the same metric, it uses the static route and discards the dynamic route. If a router has one dynamic route to a remote network but learns of another with the same metric, it retains the existing route and discards the new route. Under some circumstances, you may want your router to use the same path consistently to reach a remote network, even if another, more efficient route to the remote network exists.
Route flushing is especially important when a port is configured as a dial-in PPP interface, since the router will not be able to dial out to re-establish a link after it goes down. If route flushing is turned off, the router does not change the route's status or metric when the link goes down. Instead, it maintains its routing table entry and freezes the RIP timer for the route. When the link comes back up, the router continues aging the route without restarting its RIP timer.
PPP over Ethernet Stages PPPoE requires no additional knowledge on the part of the end user other than that needed for traditional dial-up Internet access. Multiple users can share a broadband connection without additional support or training costs, making it PPPoE ideal for small offices/home offices. Cayman’s implementation of PPPoE is compatible with networking products from Shasta/Nortel, Redback Networks, and other standard industry servers.
When the host receives the Confirmation packet from the Access Concentrator, negotiations are concluded and they can proceed to the PPP Session stage. PPP Session Stage Once the PPPoE session is operative, the host and Access Concentrator exchange PPP packets using the unique session identifier they negotiated during discovery. An Access Concentrator may periodically send ICMP Echo-Request packets to the host to verify connectivity.
