Configuring your NMS
37
The encrypted parameter means that the MD5 or SHA password will be a digest value. MD5 has
16 octets in the digest. SHA has 20. The digest string has to be entered as a hexadecimal string.
In this case, the agent need not generate any explicit digest. If the encrypted parameter is not
used, the user is expected to enter the authentication password string for MD5 or SHA. The agent
will convert the password string to a digest, as described in RFC 3414.
The auth md5 | sha parameter is optional. It defines the type of encryption that the user must
have to be authenticated. Choose between MD5 or SHA encryption. MD5 and SHA are two
authentication protocols used in SNMP version 3.
The <md5-password> and <sha-password> define the password the user must use to be
authenticated. These password must have a minimum of 8 characters. If the encrypted parameter
is used, then the digest has 16 octets for MD5 or 20 octets for SHA.
NOTE
Once a password string is entered, the generated configuration displays the digest (for security
reasons), not the actual password.
The priv [encrypted] des <des-password> parameter is optional after you enter the md5 or sha
password. The priv parameter defines the type of encryption that will be used to encrypt the
privacy password. If the "encryption" keyword is used, enter a 16-octet DES key in hexadecimal
format for the des-password. If the "encryption" keyword is not used, enter a password string of at
least 8 characters. The agent will generate a suitable 16-octet DES key from the password string:
• If DES is the privacy protocol to be used, enter des followed by a 16-octet DES key in
hexadecimal format for the <des-password-key>. If you include the encrypted keyword, enter a
password string of at least 8 characters.
• If AES is the privacy protocol to be used, enter aes followed by the AES password key. For a
small password key, enter 12 characters. For a big password key, enter 16 characters. If you
include the encrypted keyword, enter a password string containing 32 hexadecimal characters.
Displaying the engine ID
To display the engine ID of a management module, enter a command such as the following.
BigIron RX(config)# show snmp engineid
Local SNMP Engine ID: 800007c70300e05290ab60
Engine Boots: 3
Engine time: 5
Syntax: show snmp engineid
The engine ID identifies the source or destination of the packet.
The engine boots represents the number of times that the SNMP engine reinitialized itself with the
same engine ID. If the engineID is modified, the boot count is reset to 0.
The engine time represents the current time with the SNMP agent.
Displaying SNMP groups
To display the definition of an SNMP group, enter a command such as the following.
