Configuration, Initial Setup

This chapter contains configuration procedures.

This chapter contains the following:

• BPX Switch Management

• Initial Node Configuration Summary

• IP Setup and IP Relay Configuration

• Configuring the LAN Port

The BPX switch 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 Cisco WAN Manager Network Management Station (NMS) can issue BPX switch 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 Cisco WAN Manager provides end-to-end configuration management using the Connection Manager. When an IPX or IGX 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 the Cisco WAN Manager via the Connection Manager over an in-band LAN connection. (Telnet can be used to access an interface shelf (e.g., IPX or IGX shelf or MGX 8220 shelf) if a Cisco WAN Manager workstation is not available to provide in-band management.)

BPX Switch Management

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

For detailed configuration information, refer to the Cisco WAN Switch Command Reference publication.

Initial Node Configuration Summary

Adding Nodes, Adding Trunks, Shelves, etc.

Refer to the applicable reference publications, Cisco IPX Reference, Cisco BPX 8600 Series Reference, Cisco IGX 8400 Series Reference, and Cisco MGX 8220 Reference, 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 (addtrk or addshelf), as applicable. Connections can also be added now or later, after configuring the nodes for operation with the Cisco WAN Manager NMS manager.

The basic tasks to configure a BPX switch are as follows:

• Set up the node.

  • Configure the node name (cnfname).

  • Configure the time zone (cnftmzn).

  • Configure date (cnfdate).

  • Configure time (cnftime).

  • Configure the LAN interface (cnflan).

  • Configure the auxiliary or terminal ports to support any necessary external devices such as a local printer, an autodial modem, or an external multiplexer attached to the unit (cnfprt, cnfterm, cnftermfunc).

• Set up the trunks to other routing nodes.Verify the correct cards are in both the local and remote nodes (dspcds).

  • Up the trunk(s) at each node (uptrk).

  • Configure any parameters required for the trunk at each node (cnftrk).

  • Add the trunk(s) at each node (addtrk).

  • Set up Y redundancy if desired (addyred).

• If using an IPX/IGX Interface Shelf, configure it as shelf.

  • Up the trunk from the AIT/BTM to the BPX switch using (uptrk). Shelf trunks for the IPX/IGX must be upped on both the BPX routing switch and the shelf before the shelf can be joined to the Routing Network.

  • Contact Customer Service to configure the IPX/IGX shelf option.

  • At the BPX switch, add the IPX/IGX switch as a shelf to the BPX (addshelf).

The following two examples are of the screens displayed when "dspnode" is entered at a BPX switch and at one of its IPX shelves, respectively. The "dspnode" screen displayed at the "hubone' BPX switch 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 switch via AIT trunk 8.

• Adding the MGX 8220 Shelf.

  • At the BPX switch, add the MGX 8220 as a shelf to the BPX switch (addshelf).

• Set up ATM service lines and ports.

  • Activate the line (upln).

  • Configure the line (cnfln).

  • Activate the ports (upport).

  • Configure the ports (cnfport).

• Set up ATM connections.

  • Add connections (addcon).

  • Configure a connection type (cnfcontyp).

• Set up ATM to Frame Relay (ATF) connections.

  • Add the connections (addcon).

  • Configure connection classes (cnfcls).

  • Configure connection groups (addcongrp).

• Set up Interface Shelf Frame Relay Connections in Tiered Networks.

  • Refer to the Cisco WAN Manager Operations publication.

  • Only Frame Relay connections are supported from the IPX Interface Shelf and these are added and managed by the Cisco WAN Manager Connection Manager via the SNMP protocol. All connections are treated as end-to-end.

  • Frame Relay connections terminated at an MGX 8220 Shelf are added and managed by the Cisco WAN Manager Connection Manager via the SNMP protocol. All connections are treated as end-to-end.

  • ATM connections terminated at an MGX 8220 Shelf are added and managed using the Cisco WAN Manager Connection Manager via the SNMP protocol. All connections are treated as end-to-end.

IP Setup and IP Relay Configuration

In setting up network management for a network, both the Cisco WAN Manager workstation and network nodes need to be configured. Cisco WAN Manager 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.

On IPX, BPX, IGX switches, the following commands are used to configure the nodes for operation with Cisco WAN Manager: cnflan, cnfnwip, cnfstatmast, cnfsnmp. The MGX 8220 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 as shown in Figure 12-1.

Figure 12-1: Cisco WAN Manager Physical LAN and IP Relay Network

Installing Cisco WAN Manager and Associated Applications

Refer to the Cisco WAN Manager Operations, Cisco WAN Switching Command Reference, and Cisco MGX 8220 Reference publications for additional information.

Configuring the Cisco WAN Manager Workstation (example)

Step 2   Enter physical IP addresses and physical LAN node names (with a letter "p", for example, such as "nw1bpx1p", to differentiate from IP relay name) in /etc/hosts and also enter IP relay addresses with actual configured node names ("nw1bpx1", for example).

If the workstation is connected to the corporate network for access to hosts on another network, add any IP addresses and associated names of the hosts that you may want to connect to your workstation, as the NIS is disabled.

Step 3   Enter the name or IP address of the gateway node in config.sv, using physical LAN name e.g., "nw1bpx1p". Note; normally a BPX switch is used for the gateway node because of its greater processing power.

0|Network1|nw1bpx1p|9600|0|7|6|0|30|1024|9.1|

or

0|Network1|204.179.61.104|9600|0|7|6|0|30|1024|9.1|

Step 4   Enter IP Relay subnet mask in /etc/rc2.d/S72inetsvc file as follows:

Configuring the LAN Port

Normally, the System Administrator will provide the IP addresses for the workstation and node. Refer to the Cisco WAN Manager Operations manual for instructions on configuring the Cisco WAN Manager workstation.

The addresses shown are just examples. Use the addresses obtained from your System Administrator. (This example is for a workstation named "hedgehog" at address 192.187.207.200. It also assumes that the BPX, IGX, or IPX switch LAN port for node sanfran has been assigned an IP address of 192.187.210.30 and a hostname of sanfran. Your own host name and addresses will be different.)

---

Note If an NIS is being used (e.g., corporate network), you will need to contact the system administrator.

---

---

Note 5120 is used for the LAN ports on all BPX/IPX switch ports.

---

Step 2   Configure the LAN port on the BPX/IPX switch using a dumb terminal or an RS-232 connection via the workstation (using the vt command, as applicable) to enter the appropriate cnflan parameters.

The cnflan command configures the node's communication parameters so that the node can communicate with a Cisco WAN Manager terminal over an Ethernet LAN using the TCP/IP protocol. The parameters contain address information about the Ethernet TCP/IP network that is used to connect the Cisco WAN Manager station to an IGX or BPX switch. The values used must conform to those of the network and should be supplied by the Ethernet network administrator.

• Active IP Address is the Internet Protocol address of the node used in the TCP/IP protocol.

• IP Subnet Mask is a 32-bit mask. The default for a Class C LAN network is 255.255.255.0. (Other than C Class masks may be used.)

• IP Service Port is the BPX/IGX.IPX switch LAN port number entered in the /etc/service file on the workstation. It is 5120 for all BPX/IGX/IPX switches.

• Default Gateway IP Address is the Internet gateway address. This is the gateway that traffic is routed through if the BPX, IGX, or IPX switch and workstation are on different networks. If they are on the same network, the gateway is not used. The default "none" is displayed in this case. (Note: If a gateway IP is entered and later you want to remove it, enter 255.255.255.255 opposite the "IP Subnet Mask" prompt and 192.0.0.0 opposite the "Default Gateway IP Address" prompt and "none" will again be displayed. (Note: The node will reset itself if you do this.)

A cnflan screen is shown in the following example for the LAN setup shown in Figure 12-2. An IP address of 192.187.210.30 has been entered as the active IP address for the node. The IP Subnet mask is entered as 255.255.255.0 for a Class C LAN network. The TCP service port is entered as 5120. Since the workstation and node are on different networks in this example, a gateway address of 192.187.207.1 (the address of the node serving as a gateway for Cisco WAN Manager, in this example), which must be obtained from your System Administrator, has been entered. If the workstation and node are both on the same network, no gateway address is needed. The "Maximum LAN Transmit Unit" and "Ethernet Address" parameters are not configurable by the cnflan command. The "Ethernet Address" is a hardware address that is different for every node controller card, e.g., BCC.

Example: Configuring a Control Port (Gateway Router Example)

Step 3   Connect the Cisco WAN Manager workstation and the BPX switch to a LAN network. The LAN port on the BPX switch provides a DB-15 connector that can be connected to a Y-cable which in turn is connected to an AUI.

Step 4   To test that a LAN connection to the BPX switch LAN port is okay, for example, for a hostname of "sanfran" entered in the config.sv file, you could enter the following at the Cisco WAN Manager workstation:

Figure 12-3 shows an example of a Cisco WAN Manager workstation LAN connection to a BPX switch on a network with no gateway router, nor connection to another LAN. This type of LAN connection could also be connected through a "Hub" which is essentially a signal splitter (passive or active).

Configuring the MGX 8220 for Cisco WAN Manager NMS Operation (example)

At installation, initial access to the MGX 8220 is provided by the control port. The following is a brief overview of initial configuration. Refer to the Cisco MGX 8220 Reference manual for detailed information. Also refer to appropriate release notes for applicable firmware and software versions.

Step 2   Login.

Step 3   Name the shelf.

Step 4   Set the date.

Step 5   Set the time.

Step 6   Enter Help for a list of commands.

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

Step 8   Enter Ethernet LAN port IP address.

   You are configuring ethernet port are you sure? enter yes/no: yes

Step 9   Enter IP Relay Address for SNMP Management and Stats Collection.

   You are configuring atm port are you sure? enter yes/no: yes

Step 10   Configure stat master address (IP of Cisco WAN Manager workstation).

Adding Virtual Trunks using BXM Cards

Starting with switch software Release 9.2, BXM cards support virtual trunks. For additional information, refer to Chapter 15, Configuration, BXM Virtual Trunks.

Adding Virtual Trunks using BNI and ASI Cards

This section details the steps for setting up a virtual trunk. Virtual trunking is an optional feature that must be enabled by Cisco prior to adding virtual trunks. Also, revision levels of ASI and BNI firmware must be current. The following procedure assumes that Cisco equipment is used in the ATM Cloud as well as in the Cisco WAN Switching subnetworks. In this case, a BNI output from the subnetwork is connected to an ASI UNI input at the ATM Cloud (see Figure 12-4). Proceed as follows:

Figure 12-4:
Virtual Trunks across a Cisco Wan Switching ATM Cloud

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