| Description | A variable for setting the router's local engineID value.
Setting this variable will effect the value of snmpEngineID. Setting this
variable to the value '00 00 00 00 00'H will cause snmpEngineID to get
an automatically created value based on the device basic MAC address.
This method of setting the agent's engineID is recommended for stand-alone
systems. Setting this variable to any other (valid) value will set snmpEngineID
to this value. Setting this variable to all 'ff'H or all zeros is not
allowed, with the exception of the value '00 00 00 00 00'H.
The last method is recommended for stackable system, in order for the
engineID to be unique within an administrative domain.
Setting this value (to a value different then the default value)
is required before configuring users data in usmUserTable and
vacmSecurityToGroupTable.
Changing the value of this variable has 2 side-effects:
- All user data will be deleted, including: all usmUserTable configured entries and
vacmSecurityToGroupTable entries where vacmSecurityModel = 3.
- All snmpCommunityTable entries with snmpCommunityContextEngineID value
equal to old rlSnmpEngineID value, will be updated with the new
rlSnmpEngineID value. |
