Cisco LightStream 100 Release Note for Software Release 3.1(2)

This release note describes new features, caveats, and modifications for Cisco LightStream 100 Software Release 3.1(2).

Documentation

The Cisco LightStream 100 User Guide is available for the LightStream 100 Switch. This document is available in print or on the Cisco Connection Documentation, Enterprise CD-ROM.

Software Features

Release 3.1(2) Features

Software Release 3.1(2) supports the following feature in addition to those found in Software Release 3.1(1).

Maximum VPI/VCI bit learning between the LightStream 100 Switch and end stations, such as the Catalyst 5000 Series Switch.

This feature lets the LightStream 100 learn and select the number of VPI/VCI bits supported by end stations via the ILMI protocol. VPI/VCI bit values are compared with configured values for the interface between the switch and end station. The minimum of the two values is selected, and takes effect immediately.

These values can be configured on the LightStream 100 on a per-interface basis using the set interface command. Changes made to the command line interface (CLI) must be saved to nonvolatile memory and take effect after the switch is reset.

An end station, such as the Catalyst 5000 series ATM module, configures the VPI/VCI bits using the set atm vc-per-vp command, and saves the changes to nonvolatile memory. These changes take effect after the reload command is executed from the console.

For example, an end station's interface is configured to support a maximum VPI bit value of 2 and a minimum VCI bit value of 10. The corresponding interface on the LightStream 100 is configured to support a maximum VPI bit value of 4 and a minimum VCI bit value of 8. As the LightStream 100 runs through its startup procedures, it learns the end station's VPI/VCI bit values via ILMI, and selects a maximum VPI bit value of 2 and a maximum VCI bit value of 8 for the interface.

Release 3.1(1) Features

Supports point-to-multipoint switched virtual circuits (SVCs).
Supports standard TCP-UDP/IP protocol stack implementation:
- In-band ATM and out-of-band Ethernet.
- ICMP support over management virtual circuit channels.
- ICMP reply over Ethernet.
Supports two IP addresses: one for Ethernet and one for ATM.
Fully interoperable with all Cisco LAN emulation products.
Provides ILMI support in the following ways:
- ILMI address registration on UNI 3.0. (This feature has been tested successfully with the Cisco ATM Router Processor, the Catalyst 5000 Series Switch, and Cisco NIC cards.)
- LECS address discovery by the host.
- ILMI and the IP address of the neighbor.
- UNI/NNI differentiations.
Provides additional SNMP MIB objects. (These MIBs are located on cisco.ftp.com at /ftp/pub/mibs/v1/LS100-R2-MIB.my.)
Provides Enhanced SNMP/network management support.
Operation Administration and Maintenance (OAM) through both the command line interface and MIBs, including the following:
- Segment loopback generation and reporting .
- End-to-end loopback pass through.
- VPC/VCC alarm indication signals (AIS) and far end reporting failure (FERF).
Provides the following new commands, which are documented in detail in the
Cisco LightStream 100 User Guide:
- generate
- set ilmi
- delete ilmi
- display ilmi
- set compareroute
- display compareroute
- display dynamicroute
- set lbpoint
- delete lbpoint
- display lbpoint
- set configserver
- delete configserver
- display configserver

Software Release 3.1(1) and 3.1(2) Caveats

The following caveats apply to both Software Release 3.1(1) and 3.1(2).

If a default static route matches any 13-byte ILMI network prefix used on the same switch, the switch will use the default static route instead of the dynamic route to the end station. (CSCdi48021)

Workaround:

Static routes should not be configured to an address prefix that matches any 13-byte ILMI network prefixes used on the same switch. In particular, default static routes should not be configured.

The LS-100 incorrectly allows duplicate NSAP entries to exist. If a static entry for an NSAP address is entered in the LS-100 and then a station with the same NSAP address attempts to dynamically register the address on a different port, the LS-100 allows the end station to dynamically register. When routing signalling messages, the switch searches the static and dynamic routing tables and encounters the duplicate NSAP address. (CSCdi42343)

Workaround:

Avoid using the same NSAP address for different stations.

Note The LightStream 100 Switch was formerly known as the HyperSwitch A100.

Software Release 3.1(2) Modifications

The following modifications are specific to Software Release 3.1(2):

Soft PVC/PVP call forwarding originating from the LightStream 1010 has been corrected. (CSCdi51514 and CSCdi52670)
SVCs not being released when a router interface connected to the LightStream 100 is shut down has been corrected. (CSCdi51285)
OID in LECS address, GetNext, has been corrected. (CSCdi58489)

Upgrading the Software

This section provides the procedure to upgrade software stored in Flash read-only memory (ROM). This procedure uses TFTP to download new software installed on a server workstation.

Required Equipment for Upgrading Software

Have the following equipment available when upgrading the software:

Server workstation that contains new software files
LightStream 100 switch and a console terminal
Ethernet cable

Upgrade Considerations

Before performing the upgrade, consider the following important information:

Put the software images in the /tftpboot directory on the server workstation.
Do not edit the rboot.dat file on a PC. The PC removes carriage returns and line feeds from the file, making the file unreadable to the LS-100. You can edit the rboot.dat file only on a UNIX workstation.
This procedure assumes that the server workstation, a console terminal, and the LightStream 100 switch are properly installed and configured. For information on using a server workstation, refer to the system manual for that device.

Performing the Software Upgrade

To perform the upgrade, follow these steps:

Step 1 Set the power switch on back of the LightStream 100 main unit to the ON (|) position.

Step 2 Enter the enable command at the user prompt, as follows:


LS100> enable

Step 3 Enter your password when prompted, as follows


Input password: ********


LS100#

Step 4 Enter the server IP address, default route, and boot filename:

Case 1: The server and the switch have the same IP network address.

The boot filename is /tftpboot/etc/rboot.dat.

Enter the set server command and your server's address, as follows:


LS100# set server

your_server_address

Case 2: The server and the switch have different IP network addresses.

The boot filename is /tftpboot/etc/rboot.dat.

Enter the set server command, your server address, and default router IP address, as follows:


LS100# set server your_server_address default_router_ip_address

Step 5 Enter the switch IP address, as follows:


LS100# set local

switch_name switch_ip_address switch_ip_mask

Step 6 Change the boot mode to one of the following two options:

Case 1: Clear the configuration data, as follows:


LS100# set boot initialize

Case 2: Keep the configuration data, as follows:


LS100# set boot network

Step 7 Save the configuration with the save command, as follows:


LS100# save

Caution To avoid losing the configuration data you entered, after entering the save command and before pushing the Reset button, wait for the displayed output "system data has been saved." The save process can take over five minutes.

Step 8 Connect the Ethernet cable to a server workstation and the LightStream 100 switch.

Step 9 Wait until the system prompt at the console terminal is displayed, execute the reset command to reset the LightStream 100 if the switch is in a remote location or push the Reset button on the LightStream 100 front panel. The switch will load the software from the TFTP server (this can take five minutes). Verify that the yellow Status LED lights, which indicates the loading procedure is complete.

Step 10 Verify the software and ROM versions using the show version command, as follows:


LS100# show version
