EOS fallback is configurable from the CLI or via SNMP. Refer to the following section to configure
the feature on the CLI or
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
or cflash:xsr1800.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.
reload fallback primary-file {cflash: | flash:} duration [config | snmp
3. Enter the
[ip-address]] command. For example, type:
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
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 test duration to 10 minutes:
• Set test config and snmp values:
• Monitor SNMP requests from the PC with IP address 1.1.1.2:
.1.3.6.1.4.1.5624.1.2.47.1.1.7.0
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
