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 4-11 SNMP Tab Settings
on page 76 .
SNMP v3
Full-featured HP Jetdirect print servers include an SNMP v3 (Simple Network Management Protocol,
version 3) 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 an initial SNMP v3 account on the print server is created. Once
the account is created, any SNMP management application, if properly configured, can access or disable
the account.
CAUTION: If you use HP Web Jetadmin to manage your devices, you should use HP Web
Jetadmin to seamlessly configure SNMP v3 and other security settings on the print server.
Using the embedded Web server to create the SNMP v3 account will erase any existing SNMP
v3 accounts. In addition, the SNMP v3 account information will need to be implemented on the
SNMP management application.
You may create the initial account by specifying the HMAC-MD5 authentication and CBC-DES data
privacy encryption keys used by your SNMP v3 management application.
CAUTION: You should disable Telnet and ensure secure embedded Web communications
through HTTPS is enabled before creating the initial SNMP v3 account. This will help to prevent
access or interception of account information over a connection that is not secure.
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.
Other
Use this tab to enable or disable various protocols supported by the print server for printing, print
services, and management. See
Table 4-17 Other Protocols on page 92 .
Table 4-17 Other Protocols
Item Description
Enable Print Protocols Enable or disable network protocols supported by the print server: IPX/SPX, AppleTalk,
DLC/LLC. For example, you should disable unused protocols to prevent printer access
using those protocols.
For network environments that use these protocols, see Introducing the HP Jetdirect Print
Server on page 1 .
Because it uses TCP/IP, the embedded Web server does not allow disabling TCP/IP.
NOTE: HP Jetdirect 635n print servers: except for TCP/IP, network protocols
are disabled by factory default.
