C H A P T E R 4 MGX 8220 Service Modules Introduction The MGX 8220 shelf contains 16 slots. Each slot can accommodate a front card and a back card. Six slots are reserved for common equipment modules as described in Chapter 2, “Common Equipment Description”. The remaining ten slots (slots 5 through 14) are reserved for Service Modules (SMs). Service Modules provide functionality for such services as Frame Relay, ATM, and Circuit Emulation.
Chapter Frame Relay Service Modules (FRSMs) Frame Relay Service Modules (FRSMs) The primary function of the FRSM is to convert between the Frame Relay formatted data and ATM/AAL5 cell-formatted data. There are two main types of FRSMs, those for T1 or E1 lines and those for high speed serial lines.
Chapter Frame Relay Service Modules (FRSMs) FRAD (router) BPX 8620 Network with Networking Interworking Connections Frame Relay DS1 FRSM BPX 8620 network Frame Relay DS1 FRAD MGX 8220 FRSM (router) MGX 8220 PVCs IPX FRP Frame Relay DS1 FRAD (router) H8267 Figure 4-1 Cell Loss Priority and Congestion Indication for NIW connections In addition to frame-to-cell and DLCI to VPI/VCI conversion, the network interworking feature maps cell loss priority (CLP) and congestion information from Frame Relay
Chapter Frame Relay Service Modules (FRSMs) PVC Status Management The management of the ATM layer and FR PVC Status Management can operate independently. The PVC status from the ATM layer will be used when determining the status of the FR PVC. However, no direct actions of mapping LMI A bit to OAM AIS will be performed.
Chapter Frame Relay Service Modules (FRSMs) Frame Relay–to–ATM Direction Each Frame Relay–to–ATM service interworking connection can be configured as one of the following Discard Eligibility (DE) to cell loss priority (CLP) schemes: • DE bit in the Frame Relay frame is mapped to the CLP bit of every ATM cell generated by the segmentation process of the frame. • CLP is always 0. • CLP is always 1.
Chapter Frame Relay Service Modules (FRSMs) ATM to Frame Relay Direction The least-significant bit of the CPCS-UU is mapped to the C/R bit of the Frame Relay frame. Translation and Transparent Modes Each service interworking (SIW) connection can exist in either translation or transparent mode. In translation mode, the FRSM translates protocols between the FR NLPID encapsulation (RFC 1490) and the ATM LCC encapsulation (RFC 1483). In transparent mode, the FRSM does not translate.
Chapter Frame Relay Service Modules (FRSMs) ATM-to-FUNI Direction If the EFCI field in the last ATM cell of a received segmented frame is set to 1, the CN bit in the FUNI header is set to 1. The two reserve bits (the same positions as C/R and BECN in Frame Relay header) are always set to 0. FRSMs for T1 and E1 lines There are two types of FRSM modules for T1 and E1 lines—Franctional (unchannelized) modules and channelized modules.

The HSSI ports can operate either as DTE or DCE.
Chapter Frame Relay Service Modules (FRSMs) • The very high-speed FRSM (MGX-FRSM-HS2) supports all the features of the standard FRSM (service interworking, FR/ATM network, FUNI, and so on). • As with the other high-speed frame service modules, 1:1 hot-standby redundancy is supported using Y-cabling on the back cards.
Chapter Frame Relay Service Modules (FRSMs) An application of a STUN connection is shown in Figure 4-5. An SNA/SDLC device is connected to a FRASM port using SDLC protocol. The traffic is first converted to Frame Relay and then to ATM cells for transmission over the network. At the other end, the traffic is first converted back to Frame Relay and the SDLC traffic is then extracted for transmission to a front-end communication processor and then to the IBM mainframe.
Chapter Frame Relay Service Modules (FRSMs) An application of a BSTUN connection is shown in Figure 4-6. A Bisync device, such as an IBM 3270, is connected to a FRASM port using Bisync protocol. The traffic is first converted to Frame Relay and then to ATM cells for transmission over the network. At the other end, the traffic is first converted back to Frame Relay and the Bisync traffic is then extracted for transmission to a front end communication processor and then to the IBM mainframe.

Chapter Configuring the Clock Source Configuring the Clock Source IMATM has a T3/E3 interface and multiple T1/E1 interfaces. It is supposed to replace a physical long distance T3/E3 ATM trunk by a group of long distance T1/E1 lines. Had there been a physical T3/E3 line, the clock sync info automatically reaches from one end to other along with T3/E3 data traffic.
Chapter Configuring the Clock Source Thus, when we configure clock source at END B as being DS1_1 or DS1_2, and so on, we are assuming that the incoming DS1 to the END B card has a valid clock present on its T1 lines inserted by a clock derived from the END A’s T3).

This step downloads the new boot code into the ASC. c. Enter the chkflash command. This command calculates and compares the Flash checksum to verify whether the boot code is correct. d. Enter the version command. This command displays the version of the boot code currently stored in Flash memory.
Appendix C Firmware Upgrade and Downgrade Procedures Graceful Upgrade and Downgrade Procedures Procedure 24—Graceful Downgrade, 1-Core Card Set (SM only) Procedure 24 is used for 4.x to 4.y, 4x to 5.x, and 5.x to 5.y. Step 1 Check compatibility. With any downgrade technique, there is always the issue of compatibility. Any release can be downgraded to any other release, but in many instances configuration information will be lost. Hardware incompatibilities can prevent some downgrades.
Appendix C Firmware Upgrade and Downgrade Procedures Graceful Upgrade and Downgrade Procedures Step 9 For all primary and stand-alone SMs in all redundancy groups, enter the dsptotals command. This step is to examine the number of shelf connections, lines, ports, and channels after the upgrade or downgrade. The values can be compared to those before the download and, therefore, it can be established that the configuration has remained the same. Restore ASC and SM configurations if necessary.
Appendix C Firmware Upgrade and Downgrade Procedures Graceful Upgrade and Downgrade Procedures Step 6 Step 7 d. Enter the version command. This command displays the version of the boot code currently stored in Flash memory. This step downloads new firmware into the ASC. e. Enter the switchcc command to switch to the other ASC. f. Enter the tftp put AXIS_ASC_BACKUP.FW command. This step downloads the new boot code into the second ASC. g. Enter the chkflash command.
Appendix C Firmware Upgrade and Downgrade Procedures Description of Upgrade/Downgrade Terminology Description of Upgrade/Downgrade Terminology Standard A standard upgrade/downgrade technique is the simplest and fastest method for upgrading/downgrading between a pair of firmware and/or backup boot code releases. A standard technique trades traffic loss for simplicity and speed. Graceful A graceful upgrade/downgrade technique attempts to minimize traffic loss at the expense of added complexity and time.
Appendix C Firmware Upgrade and Downgrade Procedures Description of Upgrade/Downgrade Terminology tftp put The UNIX TFTP (Trivial File Transfer Program) is used to write firmware or backup boot code to the ASC Flash or disk, and to the SM Flash. Example: tftp shelf tftp> bin tftp> put AXIS_. tftp> quit The number of bytes reported as being sent by the TFTP routine should be compared with the size of the firmware or backup boot code file.
Appendix C Firmware Upgrade and Downgrade Procedures Description of Upgrade/Downgrade Terminology dspfwrevs The dspfwrevs command was first introduced in Releases 2.1.25 and 4.0.02 and later in Release 3. Any time ASC firmware is TFTP put to an ASC card running Release 2.1.25 or Release 4.0.02 (or greater), the dwpfwrevs command can be used to ensure that the ASC firmware was successfully TFTP-put to the disk. Any time SM firmware is TFTP-put to an ASC card running Release 4.0.
Appendix C Firmware Upgrade and Downgrade Procedures Description of Upgrade/Downgrade Terminology flashStartAddr and flashEndAddr The flashStartAddr and flashEndAddr commands are simply variables that determine where within Flash memory a file will be written. The ASC flashStartAddr defaults to 0xbfc00000 (ASC backup boot code) and need never be changed (the ASC firmware resides on the ASC disk in Releases 2, 3, and 4). The ASC flashEndAddr defaults to 0xbfc80000.
Appendix C Firmware Upgrade and Downgrade Procedures Description of Upgrade/Downgrade Terminology dspadrxlat Any upgrade that involves resetting the active ASC card and any downgrade in which the configuration is preserved should compare the number of shelf connections before and after the upgrade/downgrade. This is accomplished by entering the MGX 8220 ASC CLI command. shelf.1.<3|4>.ASC.
Appendix C Firmware Upgrade and Downgrade Procedures Description of Upgrade/Downgrade Terminology clrallcnf The MGX 8220 active ASC CLI command, clrallcnf, is used in place of the resetsys command as part of a downgrade in which the configuration information can not be maintained for compatibility reasons. The clrallcnf command will terminate all Telnet sessions. You must reinitiate a Telnet session after an ASC card returns to the active state.
Appendix C Firmware Upgrade and Downgrade Procedures Description of Upgrade/Downgrade Terminology Save/Restore SM Configuration The ASC card stores service module (SM) configuration information on the disk in a configuration (PRI) file. The file contains a revision which identifies the format of the configuration information. The format can change from release to release.
