Usage notes on CPU utilization and system CPU utility table
The device always insist on a password to be part of snAgGblPassword object. You can override this
requirement by entering the no snmp-server pw-check command.
By default, the object uses the value of the enable super-user password configured on the device
as the default password. To allow a device to use other authentication schemes, use the aaa
authen snmp-server default enable | local | none command.
The enable option instructs the device to use the configured enable super-user password. If the
enable super-user password is missing, then the device checks for the if implicit TACACS+ enable
password. The device stores a previous (unrelated to SNMP) implicit enable operation result and
remembers the enable password that was approved by TACACS+. You can enter the following
command to use this method.
SnmpSet(snAgGblPassword.0="<enable-password>", snAgEraseNVRAM.0=3)
The local option instructs the device to use a configured local username and password value. You
can enter the following SNMP command to use this method.
SnmpSet(snAgGblPassword.0="<username> <password>", snAgEraseNVRAM.0=3)
The none option instructs the device to ignore the value of snAgGblPassword and the
authentication check will always pass. You can enter the following SNMP command to use this
method.
SnmpSet(snAgGblPassword.0="<anything here>", snAgEraseNVRAM.0=3)
aaa authentication login default TACACS+
aaa authentication enable default TACACS+
aaa authentication enable implicit-user
The snAgGblPassword object must be set for the following objects:
• snAgCfgLoad
• snAgImgLoad
• snAgConfigFromNVRAM
• snAgEraseNVRAM
• snAgWriteNVRAM
• snAgGblTelnetPassword
• snAgReload
• snAgSystemLog
Usage notes on CPU utilization and system CPU utility table
There are three groups of CPU utilization MIB objects.
Group A consists of the following object and it is not to be used.
The object in this group can display management module CPU utilization. The data it displays is
from the last time that this object was read. If there is more than one management station reading
the object, conflict occurs because every read resets the CPU utilization until the next read. It is
recommended that this object not to be used.
