Usage Guidelines
To ensure system security, change the community strings when you log in to the system for the first time.
The default read-only community string is "storage_public", read-write community string is "storage_private".
The community is subject to the following conditions:
1. the community consists of 4 to 32 characters and is case sensitive. Its length can be changed running the "change snmp safe_strategy" command;
2. the community must comply the password complexity requirements:
a) when the password complexity is 'Normal', the community must contain special characters and at least two types of the following characters: uppercase letters, lowercase letters, and digits;
b) when the password complexity is 'High', the community must contain special characters, uppercase letters, lowercase letters, and digits;
c) when the password complexity is 'Low', the community must contain any types of the following characters: special characters, uppercase letters, lowercase letters and digits.
3. the read-only community must be different from the read-write community.
NOTE:- To ensure compatibility, the system still supprts SNMPv1 and SNMPv2c. To ensure data security, it is strongly recommended to use SNMPv3.
- You can use the "change snmp safe_strategy" command to change the policies of the community.
- The special characters include ` ~ ! @ # $ % ^ & * ( ) - _ = + \ | [ { } ] ; : ' " , < . > / ? and 'space'.
