SNMP Configuration

This chapter describes how to configure the Simple Network Management Protocol (SNMP) to manage network elements.


The Simple Network Management Protocol (SNMP) is a standard network management protocol widely used on TCP/IP networks. The SNMP framework manages network elements using a central computer, known as a network management station (NMS), on which network management software is installed. There are three SNMP versions: SNMPv1, SNMPv2c, and SNMPv3. An SNMP system can run one or more SNMP versions.

  • SNMPv1 and SNMPv2c lack of authentication capabilities, resulting in vulnerability to security threats. When security is a concern, SNMPv3 is recommended.

  • After an NMS accesses a device from the admin-VS through SNMP, the NMS can access non-admin-VSs by carrying the VSID in the community (SNMPv1/v2c) or context (SNMPv3) field of packets. If the NMS accesses a non-admin-VS from the admin-VS, the NMS is authenticated only in the non-admin-VS. For example, if community is set to public123 for the admin-VS, the NMS can use public123@vs=1 (1 indicates the VSID) to access VS1.
  • An NMS cannot access a non-admin-VS from another non-admin-VS.
