For each encryption strength, specify ciphers to identify the weakest cipher allowed. NOTE: Cipher suites support different levels of encryption strength. The cipher suites currently supported for encryption and decryption are data encryption standard (DES, 56-bit), RC4 (40-bit or 128bit), and 3DES (168-bit). SNMP Use this tab to enable or disable SNMP v1, v2c and v3 agents on the print server, depending on the print server model. For a description of SNMP selections, see Table 4-12 SNMP tab settings on page 78. SNMP v3 Full-featured HP Jetdirect print servers include an SNMP v3 agent for enhanced SNMP security. The SNMP v3 agent employs a user-based security model for SNMP v3 (RFC 2574), which features user authentication and data privacy through encryption. The SNMP v3 agent is enabled when you create an initial SNMP v3 account on the print server. Once created, any properly configured SNMP management application can access or disable the account. CAUTION: Creating SNMP v3 accounts with the embedded Web server removes existing accounts. Also, you must implement the account information on the SNMP management application.

print server model. For a description of SNMP selections, see

SNMP v3
Full-featured HP Jetdirect print servers include an SNMP v3 agent for enhanced SNMP security. The
SNMP v3 agent employs a user-based security model for SNMP v3 (RFC 2574), which features user
authentication and data privacy through encryption.
The SNMP v3 agent is enabled when you create an initial SNMP v3 account on the print server. Once
created, any properly configured SNMP management application can access or disable the account.
CAUTION:
Creating SNMP v3 accounts with the embedded Web server removes existing accounts.
Also, you must implement the account information on the SNMP management application.
It is recommended that you use HP Web Jetadmin to configure SNMP v3 and other security settings on
the print server.
To prevent access or interception during SNMP v3 account creation, disable Telnet and enable secure
embedded Web communication using HTTPS.
Create the initial SNMP account by specifying the HMAC-MD5 authentication and CBC-DES data
privacy encryption keys used by your SNMP v3 management application.
CAUTION:
SNMP v1 and v2c agents can coexist with the SNMP v3 agent. However, to fully secure
SNMP access, you should disable SNMP v1 and v2c.

services, and management. The items are described in

Because the embedded Web server uses TCP/IP, you cannot disable this protocol.
NOTE:
On HP Jetdirect 635n print servers, all network protocols except TCP/IP are
disabled by factory default.
