SSL Secure Socket Layers (SSL) version 3 enables secure HTML session s between a Sentry Remote Power Manager and a remote user. SSL provides two chie f features designed to make TCP/IP (Internet) transmitted data more secure: • Authentication – The connecting client is assured of the identity of the server.
SSH Secure Shell (SSH) version 2 enables secure netw ork terminal sessions between a Sentry Remote Power Manager and a remote user over insecure networ k. SSH provides an encrypted terminal sessions with strong authentication of both the server and client, using public-key cry ptography and is typically used as a replacement for unencrypted Telnet.
SNMP The Sentry family of products supports the Simple Network Management Protocol (SNMP). This allows network management systems to use SN MP requests to retrieve information and control power for the individual outlets. The Sentry includes an SNMP v2c agent supporting standard MIB I and MIB II objects.
Setting the trap timer The Set Traptime command sets the timer period between repeated error-condition traps. The valid range for the timer period is 1 to 65535 (in seconds). The default value for the timer period is 60 seconds. To set the trap timer: At the Sentry: prompt, type set traptime , followed by the tim er period and press Enter .
SNMP Traps The Sentry supports three types of SNMP traps. Trap s are enabled at the tower (T), infeed (I) or outlet (O) level. Trap Summary Name Level(s) Description Status T, I, O Operational status .
Load Trap The Load trap is generated whenever the total input lo ad on an infeed exceeds a preset threshold. Load traps include the reported input load, load status, Location of the Sentry, and identifier and name of the affected infeed. Any error state generates a Load trap and triggers the trap timer.
Enabling or Disabling a Load trap The Set Trap Infeed Load command is used to enable or disable an Infeed Load trap. To Enable or Disable a Load tra p: At the Sentry: prompt, type set trap infeed load , followed by the infeed name, and on or off .

LDAP The Sentry family of products supports Lightweight Di rectory Access Protocol (LDAP) Version 3. This support enables authentication with LDAP servers; user accou nts do not need to be individually created locally on each Sentry device.
Enabling and Setting up LDAP Support There are a few configuration requirements for properly enabling and setting up LDAP support. Below is an overview of the minimum requirements. Directory Services server configuration requirements: 1. Define at least one LDAP group.
Setting the search bind Distinguished Name (DN) The Set LDAP BindDN command is used to set the fully-qualified distinguished na me (FQDN) for user accounts to bind with. This is required for direct ory services that do not support anonymous binds. This field is used ONLY with Simple Binds.
