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 primary, backup, or subordinate based on its ability to run the VCM. By default, the
SNMP agent is enabled on VC-Enet modules with a read community string of "public."
The following restrictions and limitations apply:
•
You must have Administrative privileges to configure SNMP capabilities. The type of privilege required
depends on the item you are configuring.
•
The VCM GUI and CLI do not support configuration of threshold trap parameters (high-water mark,
low-water mark, and averaging period).
•
For Flex-10 connections, threshold and link state change traps reflect the state of the entire physical port.
These traps are not generated for individual FlexNICs. For more information on Flex-10 connections,
see "Flex-10 overview (on page
)."
•
When upgrading from a VC release prior to 3.00, if Fibre Channel SNMP traps were defined with the
DNS type of the Trap Destination address, upon completion of the upgrade, SNMP settings are not
applied to the VC-FC modules. As a solution, use the GUI or CLI to edit any FC SNMP trap destinations
that have a DNS name for the trap destination, and change the DNS name to an IPv4 address.
•
VC 3.00 and higher limits the number of FC PortStatus traps you can configure through the CLI to five.
Prior releases did not enforce this restriction. If you have more than five FC PortStatus traps configured
in an earlier version of VC firmware, and then you upgrade to VC 3.00 or higher, then those traps are
retained. Similarly, if you restore a configuration from an earlier version of VC firmware that contains
more than five configured FC PortStatus traps in VC 3.00 or higher, you will have more than the allowed
number of configured FC PortStatus traps. Use caution not to exceed the maximum number of
configured FC PortStatus traps in these scenarios.
The following table provides a list of MIBs and where they are supported. FlexFabric modules support the
Fibre and Fabric MIBs in addition to the Enet MIBs.

The VC Module MIB is a VC-specific MIB that describes the state of a specific VC module. In addition to
unique VC module attributes, it defines traps for reporting alerts on port statistics, such as throughput, errors,
