Enterasys Networks X-PeditionTM manual Configuring EOS Fallback on the CLI

Utilizing the Command Line Interface

•If the power to XSR fails, try another reload

•If a syntax error is indicated, examine your configuration for errors

•If XSR crashes, do not retry reloading. Contact Technical Support

EOS fallback is configurable from the CLI or via SNMP. Refer to the following section to configure the feature on the CLI or “Configuring EOS Fallback via SNMP” on page 2-35for SNMP configuration instructions.

Configuring EOS Fallback on the CLI

1.Upgrade the bootrom. Because EOS fallback is implemented partially in bootrom and partially in the router image, both the bootrom and image must be upgraded. Minimum requirements are as follows on each router type: XSR 1800 Series - bootrom 3.4, XSR 1200 Series - bootrom 1.1, XSR 3000 Series - bootrom 1.7.

Refer to “BootRom Upgrade Choices” on page 2‐29 for directions.

2.Copy the new EOS file to the XSR’s Flash or Compact Flash memory as flash:xsr1800.fls or cflash:xsr1800.fls. If you do not stipulate the flash directory, the default chosen is flash:.

Note: The XSR Series 1800 Flash directory can contain only one image, so you must load the file to

cflash:. Flash RAM in Series 1200 routers has a 16-Mbyte capacity and can hold two image files.

3.Enter the reload fallback primary-file {cflash: flash:} duration [config snmp

[ip-address]] command. For example, type: reload fallback cflash:xsr3004.fls 6 config snmp 1.1.1.2.

Refer to the CLI Reference Guide for more information on the command.

Configuring EOS Fallback via SNMP

The following procedure configures EOS fallback through the SNMP Enterasys-image-validation- mib and Enterasys-configuration-management-mib.

Caution: You must enable EOS Fallback on the CLI before specifying the primary image and rebooting the XSR. Refer to “Configuring EOS Fallback on the CLI” in the previous section.

1.Enable EOS fallback by setting the etsysImageValidationEnable OID in the Enterasys-Image-Validation-MIBto enabled.

2.Configure other parameters in this MIB. For example, set etsysImageValidationOperations to 0xa0 to enable the config and snmp tests during EOS fallback verification as follows:

•	Enable EOS fallback: set 1.1.1.1 .1.3.6.1.4.1.5624.1.2.47.1.1.1.0	1
•	Set test duration to 10 minutes: set 1.1.1.1 .1.3.6.1.4.1.5624.1.2.47.1.1.2.0		10
•	Set test config and snmp values: set 1.1.1.1 .1.3.6.1.4.1.5624.1.2.47.1.1.3.0		a0

•Monitor SNMP requests from the PC with IP address 1.1.1.2: set 1.1.1.1

.1.3.6.1.4.1.5624.1.2.47.1.1.7.0 01010102

Note: The etsysImageValidationOperations for ping is not supported.

3.Add a row to the Configuration Management Change Table that specifies the primary image: set 1.1.1.1 .1.3.6.1.4.1.5624.1.2.16.2.7.1.11.1 5

4.Set the primary file name which include the file (x.fls) and device name (flash: or cflash:): set 1.1.1.1 .1.3.6.1.4.1.5624.1.2.16.2.7.1.2.1 file://cflash:/xsr3004.fls
