you can directly enter them, as shown in Figure 4-34. If the read and write communities
have been set before and need to be modified, select Modify SNMP community first
and modify the read and write communities, as shown in Figure 4-35.
If you select ALL, the NMS can connect to the SNMP card by using either of the
preceding methods. Set NMS Address and Permission Setting for any of the three
options.
You are advised to use the secure protocol SNMPv3. When SNMPv3 is changed to
ALL/SNMPv1&SNMPv2c, the system prompts "SNMP V1/V2 is Insecure protocol". When
SNMPv1&SNMPv2c is used, the correct read/write community name must be configured for the
NMS to connect to the SNMP card.
The standard encryption algorithms MD5 and DES have security risks. You are advised to use the
secure encryption algorithms SHA and AES.
Figure 4-33 Add SNMPv3 User dialog box
Before you add an SNMPv3 user, set SNMP version to SNMPv3 or ALL.
When you choose SNMPv1&SNMPv2c to manage the UPS, the read community and write
community must be the same as those for the SNMP card. The read community must be different
from the write community.
