Page 5: Preface
This Preface provides an overview of this guide, describes guide conventions, and lists other publications that may be useful. Introduction This guide provides the required information to install the WM-4T1i, WM-4E1i, and WM-1T3i WAN modules in an Alpine 3800 series switch from Extreme Networks and perform the initial module configuration tasks. -
Page 6: Terminology -Vi
Terminology When features, functionality, or operation is specific to one of the WAN modules, the specific module name is used. Explanations about features and operations that are the same for both of the WAN modules simply refer to the product as the “module.” Conventions Table 1 and Table 2 list conventions that are used throughout this guide. - Page 7 Table 2: Text Conventions (continued) Convention Words in italicized type WAN Module Installation and User Guide Description Italics emphasize a point or denote new terms at the place where they are defined in the text.

T1/E1 physical links. The modules also have two general purpose 10/100 Mbps Ethernet ports. WM-4T1i is the designation of the T1 version, and WM-4E1i is the designation of the E1 version. Also included among the WAN modules is a one-port T3 module, designated WM-1T3i, that uses PPP for its traffic. - Page 10 Installing the WAN Module Installing the WAN Module All Alpine ™ 3800 series switch module cards (SMMi modules and I/O modules) are hot-swappable. You do not need to power off the system to remove or insert a module card. Caution: Service to Alpine modules should be performed by trained service personnel only.

Internal loopback ports are marked with the notation “iL” when displayed on the command line or with ExtremeWare Vista Web access. The WM-4E1i module has four E1 ports in place of the T1 ports found in the WM-4T1i module. It is identical in all other respects. -

New SMMi images and module images are released together, so if you upgrade both at the same time, you will be certain to have compatible images. If this is not feasible, see the Extreme Networks customer support website for compatibility information. - Page 15 Installing the WAN Module Software The module can store up to two images; a primary and a secondary. When you download a new image, you must select into which image space (primary or secondary) the new image should be placed. If not indicated, the primary image space is used. You can select which image the switch or module will load on the next reboot by using the following command: use image {slot <slot>} [primary | secondary]...

Page 17: Configuring The Wan Physical Link
Configuring the WAN Physical Link This chapter covers the following topics: • Configuring WAN Physical Links on page 2-2 • Monitoring WAN Physical Links on page 2-8 Overview In this document, WAN refers to either T1, E1, or T3 technologies. T1 is a mature technology originally developed for voice telephone transmission. -
Page 18: Red, Blue, And Yellow Alarms
Configuring the WAN Physical Link Red, Blue, and Yellow Alarms WAN links have error detection built into the link hardware. The hardware can detect different types of errors, labeled red, blue and yellow alarms. A red alarm occurs when the signal is lost or an out of frame error occurs. An out of frame error can be caused when the framing type configured for the local interface does not match the framing type of the incoming signal or when the incoming signal does not contain a framing pattern. -
Page 19: Cable Length
Configuring WAN Physical Links • Timeslots (E1) • Yellow Alarms (T1) Cable length Longer cable lengths cause greater losses for signals, so transmitter hardware must transmit at a higher level to transmit data successfully. However, too high a signal level can cause crosstalk from one cable to another. -
Page 20: Clock Source
Configuring the WAN Physical Link Clock Source A clock is used to synchronize data transmission on the line. Generally, one end of the link provides the master clock, and the other end of the link recovers the clock from the signal on the line. -
Page 21: Inband Loopback Detection
Configuring WAN Physical Links config ports <portlist> e1 framing [crc4 | no-crc4] The framing choices for T3 are C-bit and M13. To choose the T3 framing scheme, use the following command: config ports <portlist> t3 framing [c-bit | m13] Inband Loopback Detection When inband loopback detection is enabled, a specific sequence of data in the signal payload from the remote end of the T1 link will cause the local end to enter network line loopback mode and send any received signal back to the remote end. -
Page 22: Timeslots
Configuring the WAN Physical Link send an SNMP alert to the SMMi in the switch when red, yellow, or blue alarms are detected. If the module is configured to send SNMP alerts, and the switch is configured to send SNMP trap messages, then the switch will send a message to any SNMP trap receivers that have been configured. -

To configure yellow alarms, use the following command: config ports <portlist> t1 yellow [detection | generation | both | off] WAN Port Configuration Commands Table 2-1 describes the commands used to configure a WAN port.

Page 25: Near-End Loopback Modes
Monitoring WAN Physical Links to the remote end. At the remote end, the process is reversed as the framing bits are discarded and the data stream is passed to the remote system. Loopback can be enabled on the near-end of a WAN link, but only the T1 and T3 modules can enable loopback on the far-end of a link. - Page 26 Configuring the WAN Physical Link Local Loopback Mode. When the local port is enabled for local loopback, the local data stream goes into the framer and the framing bits are inserted into the data, but the data is not transmitted to the remote end. Instead, it is sent back through the local framer, the framing bits are discarded, and the original data is returned.
-
Page 27: Far-End Loopback Modes
Far-End Loopback Modes The far-end of T1 links can be enabled for the following two loopback modes: • Remote Line • Remote Payload The far-end of T3 links can be enabled for the following loopback mode: • Remote Line The remote line mode reflects the received signal back to the near-end. The remote payload mode reflects the data and regenerates the framing information back to the near-end. -

Configuring PPP and MLPPP This chapter covers the following topics: • Multilink PPP and Multilink Groups on page 3-2 • Configuring a PPP/MLPPP Link on page 3-3 • Monitoring PPP/MLPPP Links on page 3-6 • PPP/MLPPP Configuration Examples on page 3-7 Overview Point-to-Point Protocol (PPP) is used across the entire range of communication speeds and devices found on the internet. -
Page 32: Multilink Ppp And Multilink Groups
Configuring PPP and MLPPP Typically, you would create a multilink group, configure the multilink group by adding T1 or E1 ports and configuring PPP/MLPPP parameters, add the multilink group to a VLAN, and finally, enable the multilink group. For a T3 port, you would configure its PPP parameters and add it to a VLAN. Multilink PPP and Multilink Groups Each multilink PPP group is given a name, up to 16 characters in length. -
Page 33: Configuring A Ppp/Mlppp Link
<groupname> Authentication By default, no authentication is configured on PPP links since the WM-4T1i module will typically be used with leased lines—where both sides of the link are controlled and authentification is not required. If authentication is needed, the WM-4T1i module supports either PAP or CHAP. -
Page 34: Ppp Link Username
Configuring PPP and MLPPP config ppp authentication [off | chap | pap | chap-pap] [ports <portlist> | multilink <groupname>] PPP Link Username When the local end of a link initiates a PPP connection, the local end must send the appropriate authentication information. For PAP it sends the username and password, for CHAP it sends the username and must respond correctly to the challenge, and for no authentication it sends nothing. -
Page 35: Ppp/Mlppp Configuration Commands
Routed packets are transported across a PPP/MLPPP link using IP Control Protocol (IPCP), described in RFC 1332. This is the encapsulation that is familiar to most users of PPP. The routed packets do not contain Ethernet headers so cannot preserve VLAN tags. -
