2.7 PING Setup/TestLink turn-up veries connectivity to a DSLAM. PING testing takes the turn-upprocedure one step further and veries connectivity to the far end network.PING is a common method to discover whether two remote LAN segmentsusing TCP-IP protocol are connected. When receiving a PING message,Internet devices acknowledge it by sending an echo message back.After turning up the link, enter Ping Setup/Test from the main menu. Therst set of screens contain conguration items for the PING test. Enter theproper protocol used by the circuit, as well as the necessary IP addresses.The rst setting is MODE.

Note : Before performing a PING test, conrm that the link is established.

ModeOptions: LLC-BRG, LLC-RTE, CLIPoA, PPPoE, or PPPoAPress and select the protocol mode for the PING test

LLC-BRG: LLC-Bridge protocol. This follows RFC 1483 bridge encap -sulation. It supports both static and dynamic IP management.

LLC-RTE: LLC-Routed protocol. It supports only static IP addressing. CLIPoA: This refers to Classical IP over ATM according to RFC 2225.

Used only in STATIC mode.

PPPoE: PPP over Ethernet, according to standard RFC 2516 PPP overEthernet. PPPoE supports dynamic IP addressing. PPPoA: PPP over ATM, according to standard RFC 2364, PPP over AAL5.

PPPoA supports dynamic IP addressing.

The actual conguration settings depend on the selected mode, hence thefollowing subsections describe setup and PING results for each mode.

sulation is used when multiple protocol are encapsulated over a singleATM Virtual Connection.

VC MUX: This is used when only one protocol is carried over a single

ATM Virtual Connection. AUTO: Automatically detect the setting.

VPIRange: 0 through 255The default is 8, which is a typical Ethernet assignment. Along with VCI,VPI identies the next destination of a cell as it moves through a series ofATM switches on the way to its destination. This is typically assigned bythe service provider.

VCIRange: 0 through 65535The default is 35, which is a typical Ethernet assignment. Along with VPI,VCI identies the next destination of a cell as it moves through a series ofATM switches on the way to its destination. This is typically assigned bythe service provider.

IP Add

Options: STATIC or DHCP STATIC: This type of IP management means that the user has a perma -

nent IP address. For STATIC, enter the Local IP; this will be the valueused during the test.

DHCP: This refers to dynamic IP management. If selected, enter the IPaddress for the destination.


18/44

18 SA965

Dynamic management provides a way for computers to obtain protocolconguration parameters (like the local IP address) dynamically from thenetwork. In this case, the IP address is not permanent to the terminal;instead, the terminal requests an address from the DHCP server onthe network. When selecting DHCP for IP Address, the test set sends arequest to the DHCP server; the DHCP server responds and providesan IP address. Upon selecting DHCP, the Loc. IP line disappears; thenetwork dynamically assigns an IP address.

Loc. IPEnter a local IP address of the circuit under test. For LLC-BRG static modeand LLC-RTE, this is the local IP address used. For LLC-BRG DHCP mode,there is no LOCAL IP mode since a dynamically assigned local IP addressis used.

Dest. IPEnter the destination address of the device to be pinged. If pinging a gate-way, enter the gateways address for the Destination IP. Pinging the gatewayveries connectivity to the ISP.

GatewayIf required, enter a gateway address. A gateway is a device that connectsdissimilar networks and passes information between them. In TCP/IP, thedefault gateway address is the address where the Internet Protocol sendspackets destined for remote networks, unless a different route is congured.Since LLC-RTE is a pure routed mode, there is no gateway setting. Thissetting applies only to LLC-BRG mode.

2.7.2.1 LLC-BRG, LLC-RTE, and CLIP Mode PING ResultsAfter conguring, press or to begin the test. As the test proceeds,the test set displays an In Prog message.

The test set will send 10 pings at one-second intervals. One or more

responses from the destination is considered a pass. Figure 13 showsa pass sample.

Figure 13 LLC PING Test Passed

PING: PASS means the destination has received the PING messageand properly responded to the test set. This indicates that the test setcan connect to the Internet.

If the test set does not receive a response, it will display PING: FAIL.This indicates that either the destination did not receive the PING mes-sage or it did not reply.

Press to stop the test, press it again or press to restart test-ing.

Press or to PING the Dest. IP again after PING: PASS isdisplayed.

In addition to the test results, the screens also report:Loc : Provides the local IP address for the test set. For LLC-BRG static andLLC-RTE, this is the same Loc. IP address entered in the PING SETUPscreen. For LLC-BRG DHCP, Loc IP shows all zeros until the DHCP server as-

signs an IP address. When assigned, the Loc line will display this address.Dst : Provides the Destination IP address for the PING messages. This isdetermined in the conguration screen.

ST : Start Time of the test.

ET: Elapsed Time since the test was started or restarted.

If selecting LLC-BRG, DHCP IP Add, the PING results screen differs slightlyfrom Figure 13. For DHCP, the network must assign the local IP address.

There are two steps for the results:1. When the test rst begins, the Loc IP address line shows all zeros. As soon

as the DHCP server provides an IP address, it updates and DHCP displaysPass as in Figure 14:

2.7.3 PPPoA and PPPoE Mode SetupPPP (Point-to-Point Protocol) allows one or more user sessions to tunnelacross the link. This includes provisions for security and protocol negotia-tions. The test set supports two versions of PPP: PPPoE (PPP over Ethernet)and PPPoA (PPP over ATM). See Section 4.1 for protocol details.

When selecting PPP, the network security and authentication requiresnegotiation. Refer to Figure 16:

Choose the encapsulation method for carrying trafc over AAL Type 5 overATM. For details, see Section 2.7.1-Encap.

AuthOptions: NONE, PAP or CHAP

The authentication layer ensures that only a valid device establishes a con-nection with the network. Choose the following:

NONE: Use this setting when authentication is not required. Note that theUser ID and Password screens are not displayed if NONE is selected.

PAP: Password Authentication Protocol as de ned in RFC 1334. PAP isthe simplest method for authentication. It involves a two-way handshakewhere one peer sends a user name and ID to another peer element inthe network. The second peer returns an authentication-acknowledgemessage either accepting or rejecting the user name and password.

CHAP: Challenge Handshake Authentication Protocol as de ned in RFC1994. It involves a three-way handshake, in which the test set sends achallenge containing its user name. The server responses with a spe-cic identier expected for this transaction. The test set then accepts orrejects this response, when accepted the test set starts sending data.

For PPP PING results there are three stages to the test:

ROUTER: This stage identi es the connection to the Broadband RemoteAccess Server or ISP.

PPP: Identi es the account with the ISP and ensures that account veri -cation (with authentication enabled) is established.

PING represents the connection/response to the destination IP ad -dress.

PPP- PPP: In Prog means that the handshaking procedure is currently

in progress. A local IP address is not yet assigned, as indicated byall zeros for the LOCAL IP. If static IP management were selected,the LOCAL IP entered in the conguration screen would be used.

- PPP: PASS means that the authentication handshaking was suc -cessful and a local IP address has been assigned, as displayed onthe Loc line.

PING- PING: This stage has not begun yet. PING will begin as soon as

the PPP stage is completed.- PING: In Prog means that the PING test is currently in process.

As soon as the test set receives a response from the destination,it will display PASS. If the test set receives no response from thedestination, it will display FAIL.
