SNMP Configuration

●The engine ID identifies the ETEP as a unique SNMP entity. The ETEP’s engine ID must be configured on every trap recipient before traps can be authenticated and processed by the trap host.

●Three security levels are available to control access to the management information: no authentication and no encryption, authentication and no encryption, and authentication and encryption.

●Trap host users define the destination that receives the traps, plus security information about communication between SNMPv3 entities. Trap host users are defined by a user name, security level, IP address, and optional authentication and encryption parameters. The ETEP supports IPv4 and IPv6 addresses.

In order to exchange messages between an SNMP manager and ETEP agent, both parties have to be configured with the same user. The manager also has to know the ETEP’s engine ID. If you want to authenticate communications, the authentication algorithm and authentication key must be known to both parties. For encryption, two more pieces of information are necessary: the encryption algorithm and encryption key. The keys are generated from the authentication and encryption passwords.

Other notes about the SNMPv3 implementation on the ETEP:

●Traps apply globally to all trap host users. The ETEP does not support trap filtering to individual hosts.

●The ETEP supports SMNPv3 MIB walks when authentication is enabled (security level set to authNoPriv or authPriv).

●To use SNMPv3 with encryption when in FIPS mode, SNMP traffic for each trap host must be secured in an IPsec tunnel.

When using SNMPv3 on the ETEP, do the following:

1Configure the system information and community string.

2Select the traps to enable on the ETEP.

3Select a method for generating the engine ID.

4Configure the SNMPv3 trap host users.
