A Console Terminal Server with SNMP Support Capabilities Can Simplify Out of Band Management

A console terminal server with SNMP compatibility can provide network administrators with a number of extremely valuable tools that simplify the process of managing important network elements located at remote, off-site network equipment sites. SNMP compatibility enables administrators to use MIB objects to change configuration parameters, check unit status and add or remove user accounts, and in addition, also provides the ability to forward data collected from attached devices to the appropriate network support personnel.

When SNMP is supported, MIB objects can be used to change configuration parameters for remote console terminal server units. Remote configuration via MIB object is a pretty handy capability when your network infrastructure includes only one or two console terminal servers, but it is absolutely vital if your network includes dozens of console terminal server units, located at many different remote installation sites. Support for MIB objects allows administrators to configure a series of identical console terminal server units by simply sending the same MIB command file to each unit in the series. This allows network administrators to easily configure a number of console terminal server units with the same parameters, or same user account information by simply broadcasting or re-sending the MIB commands to each desired console terminal server.

SNMP support also comes in hand in applications where the console terminal server is used to collect data from the devices connected to the console terminal server serial ports. Data received at each serial port can be immediately forwarded via SNMP trap to the appropriate personnel as it is received.

In cases where the console terminal server is configured to generate environmental alarms or event alarms, SNMP traps can also be used to notify administrators when an alarm is triggered. Temperature alarms, invalid access alarms, ping response failure alarms, power condition alarms and lost communication alarms can all employ SNMP traps to notify personnel at up to three different addresses when the console terminal server detects that a condition or event has tripped an alarm.

SNMP capability is just one of many features that network administrators should look for when choosing a serial console server product. Ideally, the console terminal server unit should include an assortment features that make it easier for administrators to configure, control and access console terminal servers at remote network installations, without the requirement that the administrator travel to the remote network site in person, just to perform simple configuration, diagnostic or troubleshooting tasks.
