Firewall SNMP MIB OID ordering changes after firewall reboot

SNMP walk before firewall reboot:

ENTITY-MIB::entPhysicalName.1 = STRING: PA-3220
ENTITY-MIB::entPhysicalName.2 = STRING: Fan Tray
ENTITY-MIB::entPhysicalName.3 = STRING: Fan #1 RPM
ENTITY-MIB::entPhysicalName.4 = STRING: Fan #2 RPM
ENTITY-MIB::entPhysicalName.5 = STRING: Fan #3 RPM
ENTITY-MIB::entPhysicalName.6 = STRING: Temperature: Broadwell MP Core
ENTITY-MIB::entPhysicalName.7 = STRING: Temperature @ Rear Left[U54]
ENTITY-MIB::entPhysicalName.8 = STRING: Temperature @ Front Left[U62]
ENTITY-MIB::entPhysicalName.9 = STRING: Temperature @ Rear Right[U121]
ENTITY-MIB::entPhysicalName.10 = STRING: Temperature @ Front Right[U101]
ENTITY-MIB::entPhysicalName.11 = STRING: Temperature: 73XX DP Core

• PAN-OS 10.1.x
• SNMP

Software Design.

1. New command is introduced to fix the MB ordering issue.
2. This command will reset the SNMP OID database and restart the snmpd.
3. Run the command on firewall with is rebooted, or having mis-ordered SNMP MIB table.
