Presentation transcript:

SNMP Terms SNMP Agent (network element to monitor) SNMP Management Station Community String (password) SMI (Structure of Management Info) MIB (Management Information Base) ASN.1 (Abstract Syntax Notation 1)

ASN.1 - Abstract Syntax Notation SNMP uses a subset of ASN.1 datatypes –Integer, Octet, String, Object Identifier, Sequence, Null Basic encoding rules compile language into sequence of octets Lexographic ordering allows agent to answer requests without knowing data object size

SNMP Control Flow Management Station Polls Agent –Typically every 5 minutes Agent Sends Unsolicited SNMP Traps –Agent alerts management station as needed

Agent Commands set-request –Set a variable or cause an action, need Read/Write access get-request –Fetch a data object get-next-request –Walk through a table get-bulk-request –Get in bulk for efficiency

Data Object Naming Naming hierarchy uses numbers or names, relative or absolute naming –system.sysDescr.0 –1.1.0 –1.sysDescr.0 – –.iso.org.dod.internet.mgmt.mib.system.sysdescr.0 – sysdescr.0
