SNMP is a commonly supported management protocol for most routers and switches. It is a simple protocol where a management system (such as Traverse) queries devices (such as routers and switches) for metrics, and the devices respond with the values for the queried metrics. Traverse supports all versions of SNMP: v1, v2c and v3.
SNMP Version - 1, 2c or 3 - The SNMP protocol version.
SNMP Community String
If SNMP Version 1 or 2c is selected - Enter the community name in the SNMP Community String field. The default read/write community name is public. The default read-only community name is private.
If SNMP Version 3 is selected - Enter the username, password and encryption_phrase in the SNMP Community String field using the following format: username:password:encryption_phrase. Example: myUser:myPassword:encryptMe
SNMP Agent Port - Defaults to 161.
SNMP Query Optimization - Enabled or Disabled (not recommended) - If enabled, increases the performance and efficiency of the SNMP monitor and reduces Traverse-initiated network communications. If disabled, Traverse stops grouping SNMP queries targeted for that device in a single packet. Each test is executed through a new UDP packet with a single SNMP GET request. This will allows Traverse to monitor older devices that are unable to process multiple queries in a single request, or devices that restrict packet sizes. Disabling SNMP Query Optimization adversely affects overall scalability and should be done only when absolutely necessary.
SNMPv3 Authentication Protocol - None, MD5, or SHA1 - Sets the password encryption method.
SNMPv3 Encryption Protocol - None, DES, AES - Sets the data encryption method.
Test Parameters
Field
Description
Test Name
Enter/modify the name of the test.
Interval
Use the drop-down menu to specify the interval at which Traverse executes the test.
Thresholds (warn/critical)
Enter/modify the threshold levels that cause the test to change to (a state of) Warning or Critical, respectively.
