SNMP Support
Built-in support for Simple Network Management Protocol (SNMP) allows users to integrate a SFS 7024
into their existing management frameworks. SNMP allows users access to all statistics, trend analysis,
alarm handling, filtering, and performance monitoring capabilities supported by these management
frameworks.

SNMP MIBs

SNMP Management Information Bases (MIBs) are management elem ents that are used by industry
frameworks to monitor information about the SFS 7024 switch. The SFS 7024 switch supports MIBs
from the following sources:
• Switch-sourced MIBs: MIBs from the CMU of the SFS 7024 provide status information regarding
the physical environment of the switch. Additionally, the CMU MIBs provide status and activity
information for all line cards residing in the switch.
