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 2-35 for 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

cflash:xsr1800.fls. If you do not stipulate the flash directory, the default chosen is flash:.

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.

Configuring EOS Fallback via SNMP

The following procedure configures EOS fallback through the SNMP Enterasys-image-validation-

mib and Enterasys-configuration-management-mib.

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

Validation-MIB to

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

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

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.

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.

Note: The etsysImageValidationOperations for ping is not supported.
