Establishing SNMP community strings
40
To add an encrypted community string, enter commands such as the following.
PowerConnect(config)#snmp-server community private rw
PowerConnect(config)#write memory
Syntax: snmp-server community [0 | 1] <string>
ro | rw [view <viewname>] [<standard-ACL-name> | <standard-ACL-id>]
The <string> parameter specifies the community string name. The string can be up to 32
characters long.
The ro | rw parameter specifies whether the string is read-only (ro) or read-write (rw).
The 0 | 1 parameter affects encryption for display of the string in the running-config and the
startup-config file. Encryption is enabled by default. When encryption is enabled, the community
string is encrypted in the CLI regardless of the access level you are using. In the Web Management
Interface, the community string is encrypted at the read-only access level but is visible at the
read-write access level.
The encryption option can be omitted (the default) or can be one of the following:
• 0 – Disables encryption for the community string you specify with the command. The
community string is shown as clear text in the running-config and the startup-config file. Use
this option if you do not want the display of the community string to be encrypted.
• 1 – Assumes that the community string you enter is encrypted, and decrypts the value before
using it.
NOTE
If you want the software to assume that the value you enter is the clear-text form, and to encrypt
display of that form, do not enter 0 or 1. Instead, omit the encryption option and allow the software
to use the default behavior.
NOTE
If you specify encryption option 1, the software assumes that you are entering the encrypted form
of the community string. In this case, the software decrypts the community string you enter before
using the value for authentication. If you accidentally enter option 1 followed by the clear-text
version of the community string, authentication will fail because the value used by the software will
not match the value you intended to use.
The command in the example above adds the read-write SNMP community string “private”. When
you save the new community string to the startup-config file (using the write memory command),
the software adds the following command to the file.
snmp-server community 1 <encrypted-string> rw
To add a non-encrypted community string, you must explicitly specify that you do not want the
software to encrypt the string. Here is an example.
PowerConnect(config)#snmp-server community 0 private rw
PowerConnect(config)#write memory
The command in this example adds the string “private” in the clear, which means the string is
displayed in the clear. When you save the new community string to the startup-config file, the
software adds the following command to the file.
snmp-server community 0 private rw
