SNMP, or Simple Network Management Protocol, is an Internet standard protocol for remote management. You might use this instead of Enterprise Cloud Manager if you want to remotely manage a set of routers that include both CradlePoint and non-CradlePoint products.
- Enable SNMP: Selecting “Enable SNMP” will reveal the router’s SNMP configuration options.
- Enable SNMP on LAN: Enabling SNMP on LAN will make SNMP services available on the LAN networks provided by this router. SNMP will not be available on guest or virtual networks that do not have administrative access.
- LAN port #: Use the LAN port # field to configure the LAN port number you wish to access SNMP services on. (Default: 161)
- Enable SNMP on WAN: Enabling SNMP on WAN will make SNMP services available to the WAN interfaces of the router.
- WAN port #: Use the WAN port # field to configure which publicly accessible port you wish to make SNMP services available on. (Default: 161)
- SNMPv1: SNMP version 1 is the most basic version of SNMP. SNMPv1 will configure the router to transmit with settings compatible with SNMP version 1 protocols.
- SNMPv2c: SNMP version 2c has the same features as v1 with some additional commands. SNMPv2c will configure the router to use settings and data formatting compatible with SNMP version 2c.
- SNMPv3: SNMP version 3 includes all prior features with security available. SNMPv3 is the most secure setting for SNMP. If you wish to configure traps then you must use SNMP version 3.
- Get community string: The “Get community string” is used to read SNMP information from the router. This string is like a password that is transmitted in regular text with no protection.
- Set community string: The “Set community string” is used when writing SNMP settings to the router. This string is like a password. It is a good idea to make it different than the “Get community string.”
If you select SNMPv3, you have several additional configuration options for added security.
- Authentication type: Select the authentication and encryption type that will be used when connecting to the router from the following dropdown list. These settings must match the configuration used on any SNMP clients.
- MD5 with no encryption
- SHA with no encryption
- MD5 with DES encryption
- SHA with DES encryption
- MD5 with AES encryption
- SHA with AES encryption
- Username: Enter the Username configured on your SNMP host in the username field.
- Password: Enter the Password for your SNMP host in the password and verify password fields. This password must be at least 8 characters long.
- Enable SNMP traps: Enabling traps will allow you to configure a destination server, community, and port for trap notifications. Trap notifications are returned to the server with SNMPv1.
- Trap community string: The trap notifications will be returned to the trap server using this SNMPv1 trap community name.
- Address for trap server: Enter the address of the host system that you want trap alerts sent to.
- Trap server port #: Enter the port number that the remote host will be listening for trap alerts on. (Default: 162)
System information via SNMP is Read-Writable by default. However, if a value is set here, that field will become Read-Only.
- System Contact: Input the email address of the system administrator.
- System Name: Input the router’s hostname.
- System Location: Input the physical location of the router. This is simply a string for your own information.
