Configuring SNMP 143

„3des—Triple DES encryption is used.

„aes—Advanced Encryption Standard (AES) encryption is used.

If the encryption type is des, 3des, or aes, you can specify a passphrase or a hexadecimal key.

„To specify a passphrase, use the encrypt-pass-phrasestring option. The string can be from 8 to 32 alphanumeric characters long, with no spaces. Type a string at least 8 characters long for DES or 3DES, or at least 12 characters long for AES.

„To specify a key, use the encrypt-keyhex-stringoption. Type a 16-byte hexadecimal string.

Command Examples

The following command creates USM user snmpmgr1, associated with the local SNMP engine ID. This user can send traps to notification receivers.

WX1200# set snmp usm snmpmgr1 snmp-engine-id local success: change accepted.

The following command creates USM user securesnmpmgr1, which uses SHA authentication and 3DES encryption with passphrases. This user can send informs to the notification receiver that has engine ID 192.168.40.2.

WX1200# set snmp usm securesnmpmgr1 snmp-engine-id ip 192.168.40.2 auth-type sha auth-pass-phrase myauthpword encrypt-type 3des encrypt-pass-phrase mycryptpword success: change accepted.

Setting SNMP By default, MSS allows nonsecure SNMP message exchanges. You can Security configure MSS to require secure SNMP exchanges instead.

Depending on the level of security you want MSS to enforce, you can require authentication of message exchanges only, or of message exchanges and notifications. You also can require encryption in addition to authentication.

SNMPv1 and SNMPv2c do not support authentication or encryption. If you plan to use SNMPv1 or SNMPv2c, leave the minimum level of SNMP security set to unsecured.
