ECS 3.5.0.1 Administration Guide

SNMP servers

Simple Network Management Protocol (SNMP) servers, also known as SNMP agents, provide data about network managed device status and statistics to SNMP Network Management Station clients.

To allow communication between SNMP agents and SNMP Network Management Station clients, you must configure both sides to use the same credentials. For SNMPv2, both sides must use the same Community name. For SNMPv3, both sides must use the same Engine ID, username, authentication protocol and authentication passphrase, and privacy protocol and privacy passphrase.

To authenticate traffic between SNMPv3 servers and SNMP Network Management Station clients, and to verify message integrity between hosts, ECS supports the SNMPv3 standard use of the following cryptographic hash functions:

• Message Digest 5 (MD5)
• Secure Hash Algorithm 1 (SHA-1)

To encrypt all traffic between SNMPv3 servers and SNMP Network Management Station clients, ECS supports encryption of SNMPv3 traffic by using the following cryptographic protocols:

• Digital Encryption Standard (using 56-bit keys)
• Advanced Encryption Standard (using 128-bit, 192-bit or 256-bit keys)
