SNMP (PSM_Root)

This topic provides information about configuring the Network device monitor using Central Monitoring Administration. The Network device (SNMP) monitor type is used to configure network devices such as Switches, Routers ,Load Balancers, Servers and so on to collect data based on SNMP data-collection. The following steps are required for configuration:

In the Add Monitor Types dialog box, with the Monitoring Profile set to SNMP, and the Monitor Type set to Network device , provide the following details:

FieldDescription

Network devices

Network device details

Device name/IP

Enter the alias name, host name or IP address of the network device you want to monitor.

If you have provided alias name as the device name, then you must configure the device IP address by providing the IP address in the Forced IP Address field.

Forced IP Address

(Optional) Enter the IP address of the network device you want to monitor.

You can leave this field blank if you have provided the actual host nameor IP address in the Device name/IP field.

Category

Enter a category name to group network devices. The default category is "Network".

Port

Enter the port number of the SNMP agent.

The default port number is 161.

Poll interval (sec)Select the polling interval time in seconds. The default value is 300 seconds. The minimum value is 10 seconds and the maximum value is 3600 seconds.
Retries count

Select the number of retries for sending SNMP queries to the network device. The default value is 2. The minimum value is 1 and the maximum value is 4.

Timeout (sec)Enter the timeout in seconds to wait for each reply of SNMP queries. The default value is 2 seconds. The minimum value is 1 second and the maximum value is 300 seconds.
Community string

Enter the community string to allow access to the network device.

SNMP Community strings are used only by devices which support SNMPv1 and SNMPv2c protocol. SNMPv3 uses the user name and password authentication, along with an encryption key.

Version

Select one of the following SNMP version, which is supported by the network device:

  • 1
  • 2C
  • 3

V3 settings

Authorization user credentials

If you have selected SNMP version 3, provide the following details:
User NameEnter the user name to configure the SNMP.
PasswordEnter a password.
Confirm PasswordRe-enter the password to confirm.
Authorization protocol

Select one of the following authentication protocol to authenticate the user:

  • MD5
  • SHA
Privacy protocol

Select one of the following privacy protocol:

  • CBS-DES
  • CFB-AES-128

The privacy allows for encryption of SNMP v3 messages to ensure confidentiality of data. These protocols provide a higher level of security than is available in SNMP v1 and v2c, which use community strings for security.

Privacy passowordEnter a password to access the SNMP agent.
