SNMP overview
SNMP is used by network management systems to monitor network-attached devices for conditions that
require administrative attention. SNMP consists of a set of standards for network management, including
an Application Layer protocol, a database schema, and a set of data objects.
The SNMP configuration is controlled by the Virtual Connect Manager and applies to all modules in the
VC domain. The SNMP agent software residing on a primary module provides access to managed
information using SNMP protocol. The managed information is presented as a hierarchical database
called MIB. Each element of the managed information is identified by a unique identifier called Object ID.
Basic SNMP support is provided for both the VC-Enet module and the VC-FC module.
Each VC module has an independent SNMP agent that supports a set of MIBs. MIB support for each
module depends both on the type of module (VC-Enet or VC-FC) and the role of the module in the VC
domain. A VC-Enet module can be active, standby, or subordinate based on its ability to run the VC
Manager. By default, the SNMP agent is enabled on VC-Enet modules with a read community string of
"public."
The following restrictions and limitations apply:
• Users must have Administrative privileges to configure SNMP capabilities.
• The VCM GUI and CLI do not support configuration of threshold trap parameters (high-water mark,
low-water mark, and averaging period).
