Configuration and Management

BPX Configuration (Preliminary)

This chapter contains preliminary procedures. Refer to the Command Reference, the AXIS Reference Manual, and StrataCom ISC for more detailed information.

The BPX node can be accessed through a local control port (over an RS-232 or Ethernet TCP/IP link. An administration screen from a control terminal or from the StrataView Plus Network Management Station (NMS) can issue BPX commands. Remote control terminal access is possible using a Virtual Terminal (vt) command if the node has been configured with a name and at least one trunk to the network has been established.

For frame relay connections in both tiered and non-tiered networks StrataView Plus provides end-to-end configuration management using the Connection Manager. When the IPX is configured as an Interface Shelf, it can not be reached by the vt command, and frame relay end-to-end connections are configured from StrataView Plus via the Connection Manager over an in-band LAN connection. (Note: Telnet can be used to access an interface shelf (e.g., IPX shelf or AXIS shelf) if a SV+ workstation is not available to provide in-band management.)

The only type of IPX shelf connections supported for Rel. 8.2 are frame relay to frame relay connections and frame relay interworking connections. However, on the IPX, all types of DAXCONS (connections in and out the same IPX shelf) are supported, voice, data, etc. For Release 8.2, the AXIS shelf includes frame relay interworking connections, ATM connections, and FUNI connections.

Initial Setup

The basic tasks to configure an BPX are as follows:

Figure 3-1 and Figure 3-2 are examples of the screens displayed when "dspnode" is entered at a BPX and at one of its IPX shelves, respectively. The "dspnode" screen displayed at the "hubone' bpx node shows that it is connected to the "shlf3ipx" node via BNI trunk 3.3. The "dspnode" screen displayed at the "shlf3ipx" node show that it is connected to the bpx via AIT trunk 8.

Adding Virtual Trunks

This section details the steps for setting up a virtual trunk. Virtual trunking is an optional feature that must be enabled by StrataCom prior to adding virtual trunks. Also, revision levels of ASI and BNI firmware must be current. The following procedure assumes that StrataCom equipment is used in the ATM Cloud as well as in the StrataCom subnetworks. In this case, a BNI output from the subnetwork is connected to an ASI UNI input at the ATM Cloud (Figure 3-3). Proceed as follows:

    1. In the ATM cloud network, physically connect an ASI port at the cloud edge to each BNI port in the StrataCom Network that is intended to have virtual trunks.


Figure 3-3:
Virtual Trunks across a StrataCom ATM Cloud

    2. Configure the cloud ASI ports. For each ASI port connected to a BNI virtual trunk port, do the following:

  upln <slot.port>
  upport <slot.port>
  cnfport <slot.port> and set the shift parameter to "N" for no shift if the cloud contains StrataCom nodes.

    3. Execute addcon. In the cloud network, add a virtual path ASI connection for each virtual trunk that is to route through the cloud. An example of this syntax for this is:

  addcon joker 5.1.1.* swstorm 6.2.10.*
  where 5.1 and 6.2 are ASI ports hooked up and configured for virtual trunking. Daxcons are acceptable.
  Note that the third number is the VPI which must correspond to the virtual trunk VPI configured with cnftrk in step 4.
  When the cloud is a public ATM service and not a StrataCom cloud, the VPI is provided by the carrier, as well as the guaranteed BW associated with the VPI.
  The CBR/VBR/ABR parameters must also correspond to the Virtual Trunk Type of the virtual trunk. For T3, set PCR to the bandwidth of the virtual trunk, and CDVT to 24000 for the connection so that the ASI does not drop cells. These are values that StrataCom recommends based on testing.

    4. Configure BNI virtual trunks. On the BNIs that connect to the cloud ASI ports, configure up to 32 virtual trunks, as follows:

  uptrk <slot.port.vtrk>
  cnftrk <slot.port.vtrk>
  For cnftrk, make sure that the virtual trunk type and the VPI correspond to the ASI Virtual Path connections that have been set up.
  addtrk <slot.port.vtrk>
  For further information, refer to the Command Reference Manual.

BPX Management

You can monitor, manage and troubleshoot the BPX using the StrataView Plus Network Management Station. Commands are issued to a BPX node through the Node Administration window. Frame Relay connections are added via the StrataView Plus Connection Manager. You can display and monitor the network's topology, monitor alarms, events, and statistics. Refer to the StrataView Plus Operations Guide for more information.

For detailed configuration information, refer to the Command Reference Manual.

IP, IP Relay Configuration (Preliminary)

In setting up network management for a network, both the SV+ workstation and network nodes need to be configured. SV+ communicates over a standard physical LAN network to a gateway node or nodes, but a separate in-band IP relay network is setup for all nodes via a gateway node for SNMP and TFTP in-band communication over the node trunks (Figure 3-4).


Figure 3-4: SV+ Physical LAN and IP Relay Network

Installing SV+ and Associated Applications

Refer to the StrataView Plus Installation manual, the Command Reference, and the AXIS Reference Manual for additional information.

Configure SV+ Workstation (example)

    1. Enter physical IP addresses and physcial LAN node names (with a letter"p", for example to differentiate from IP relay name) in /etc/hosts and enter IP relay addresses and actual node names.

beacon% more /etc/hosts # # Sun Host Database # # If the NIS is running, this file is only consulted when booting # 127.0.0.1 localhost # 204.179.61.121 beacon loghost # node physical ethernet LAN addresses 204.179.61.104 nw1bpx1p 204.179.61.71 nw1axi1p # node ip relay addresses 204.179.55.101 nw1ipx1 204.179.55.102 nw1ipx2 204.179.55.103 nw1ipx3 204.179.55.123 nw1igx1 204.179.55.111 nw1bpx1 204.179.55.105 nw1axi1
  If the workstation is connected to the corporate network, add any IP addresses and associated names of hosts that you may want to connect to your workstation, as the NIS is disabled.

    2. Enter name of gateway node in config.sv, using physical LAN name.g., nw1bpx1p. Note; normally, a bpx is used for the gateway node because of its greater processing power.

  0|Network1|nw1bpx1p|9600|0|7|6|0|30|1024|8.1|

    3. Enter IP Relay subnet mask at end of rc.local file:

  # route add for SV+
  route add net 204.179.55.0 nw1ipx1p 1

Note The route add command is for all nodes in the 204.179.55.0 subnetwork. The name "nw1bpx1p" is the name associated with the physical LAN port on the gateway node, e.g., nw1bpx1

    4. Contact Corporate Network Administrator, but in order for workstation to use /etc/hosts, it must not be able to access the NIS directory. A work around is to perform the following:

  mv /etc/defaultdomain /etc/defaultdomain_old

Network Node Configuration (Preliminary)

Adding nodes, adding trunks, shelves, etc.

Refer to the applicable Reference manuals, IPX, BPX, IGX, AXIS, etc., for node installation and operation.

As a minimum, the nodes need to be configured with name (cnfname), date (cnfdate), time (cnftime), timezone (cnftmzn), and trunks upped (uptrk) and added (uptrk or addshelf, as applicable. Connections can also be added now, or added later, after configuring the nodes for operation with the SV+ NMS manager.

Configuring the IPX, IGX, and BPX for SV+ NMS Operation

On IPX, BPX, IGX nodes the following commands are used to configure the nodes for operation with SV+: cnflan, cnfnwip, cnfstatmast, cnfsnmp. The AXIS is configured with cnfifip and cnfstatsmgr. The cnflan command is only necessary for nodes or shelves in which the LAN port is actually connected to a physical Ethernet LAN,

Configuring the AXIS for SV+ NMS Operation (example)

At installation, initial access to the AXIS is provided by the control port.

    1. Connect a terminal to the control port on the AXIS workstation.

    2. Login

login: "LoginID" password: card number: 3 xxxxAXIS.1.3.ASC.a >

    3. Name the shelf

xxxxAXIS.1.3.ASC.a > cnfname nw1axi1

    4. Set the date:

nw1nw1axi1.1.3.ASC.a > cnfdate 05/02/96

    5. Set the time:

nw1saxi1.1.3.ASC.a > cnftime 15:31:00

    6. Enter Help for a list of commands:

nw1saxi1.1.3.ASC.a > Help

    7. Check versions of ASC, and Service Module (e.g., FRSM, AUSM) Firmware

nw1axi1.1.3.ASC.a > version ***** Stratacom Inc. AXIS ASC Card *****2 Firmware Version = 2.1.12b_______ Backup Boot version = model-B BT_2.0.0_______ ASCFRSM Xilinx file = asc025.h ASCBNM Xilinx file = bnmt3andsrefix VxWorks (for STRATACOM) version 5.1.1-R3000. Kernel: WIND version 2.4. Made on Thu May 2 16:42:36 PDT 1996. Boot line: sl(0,0) cc

    8. Enter Ethernet LAN port IP address

nw1axi1.1.3.ASC.a > cnfifip cnfifip "-ip <ip addr> -if <Interface> -msk <NetMask> -bc <Brocast addr> " -ip <IP addr> where IP addr = nnn.nnn.nnn.nnn -if <Interface> where Interface = 26,28,37, 26: Ethernet, 28: Slip 37: ATM -msk <NetMask> where NetMask = nnn.nnn.nnn.nnn -bc <BrocastAddr> where BrocastAddr = nnnnnnnn, n is hexdecimal, ethernet only nw1axi1.1.3.ASC.a > cnfifip -ip 204.179.61.71 -if 26
