clsEmergencyImageVersion

Module: CISCO-LWAPP-SYS-MIB

OID (symbolic): CISCO-LWAPP-SYS-MIB::clsEmergencyImageVersion

OID (numeric): 1.3.6.1.4.1.9.9.618.1.3.1

Node type: OBJECT-TYPE

Type: SnmpAdminString

Access: read-only

Description: This object represents Cisco recommends installing Cisco Unified Wireless Network Controller Boot Software , (*_ER.aes , where star denotes the version of the controller image ) on all controller platforms. If this ER.aes is not installed, the controller would not be able to show the Emergency Image Version correctly(or Field Recovery Image Version), and would be shown as 'N/A'. The ER.aes files are independent from the controller software files. Any controller software file can be run with any ER.aes file. However, installing the latest boot software file (*_ER.aes , where star denotes the controller version) ensures that the boot software modifications in all of the previous and current boot software ER.aes files are installed.

What is clsEmergencyImageVersion?

Reports the version of the Cisco emergency/recovery boot software (ER.aes) image installed on the wireless controller, which is needed for the controller to recover from certain failures.
