DVS-108 Series Managed Industrial Ethernet Switches User Manual 3.2.2.1 User Configuration The following default users are preconfigured for SNMPv3: admin: All admin users can access data with a read/write permission. guest: All IP guest users can access data with a read-only permission. SNMP User Configuration 3.3 Network Redundancy In some network environments, users need to set up redundant loops in the network to provide a backup path for disconnection or network device breakdown. But if there are many network devices in the network, then each host needs to spend more time and cross many network devices to associate with each other.
And sometimes the disconnection happens in a busy network, so the network must recover in a short time. Setting up redundancy on your network helps protect critical links against failure, protects against network loops, and keeps network downtime at a minimum. 3-40 Description Factory Default User Name Enter a case-sensitive string. The maximum length is 32 characters. None Authentication Protocol Specify the authentication protocol, if any, for the user: No Authentication: Users can access data without authentication. If you select this item, the Authentication Key, Privacy Protocol, and Privacy Key fields are masked out and can’t be configured. HMAC-MD5:
Users are authenticated by Hash-based Message Authentication Code (HMAC) with MD5. If you select this item, please enter a password in the Authentication Key field. HMAC-SHA: Users are authenticated by HMAC with SHA-1. If you select this item, please enter a password in the Authentication Key field. None Authentication Key If the authentication protocol is HMAC-MD5 or HMAC-SHA, please enter a case-sensitive string for password. The maximum length is 40 characters. None Private Protocol If the authentication protocol is HMAC-MD5 or HMAC-SHA, you can specify whether to use an SNMPv3 privacy protocol (encryption) for the user: No Privacy: The users can access data without encryption. DES:
User communication is encrypted by Data Encryption Standard (DES). You need to enter a password in the Privacy Key field. None Privacy Key If the privacy protocol is DES, please enter a case-sensitive string for password. The maximum length is 40 characters. None Access Mode Specify the access mode: ReadOnly: The client can only have read permission to get information.
