SNMP community strings 6
NOTE
If you issue a no snmp-server community public ro command and then enter a write memory
command to save that configuration, the “public” community name is removed and will have no
SNMP access. If for some reason the device is brought down and then brought up, the “no
snmp-server community public ro” command is restored in the system and the “public” community
string has no SNMP access.
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.
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.
Configuring snmp-server community private rw 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.
Brocade(config)#snmp-server community 0 private rw
Brocade(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
The view <viewname> parameter is optional. It allows you to associate a view to the members of
this community string. Enter up to 32 alphanumeric characters. If no view is specified, access to
the full MIB is granted. The view that you want must exist before you can associate it to a
community string. Here is an example of how to use the view parameter in the community string
command.
Brocade(config)#snmp-s community myread ro view sysview
