For information about connecting to a switch port, refer to the switch hardware installation guide.
SNMP Network Management Platforms
You can manage switches by using an Simple Network Management Protocol (SNMP)-compatible
management station running such platforms as HP OpenView or SunNet Manager. CiscoWorks2000 and
CiscoView 5.0 are network-management applications that you can use to configure, monitor, and
troubleshoot Catalyst 2950 switches.
The switch supports a comprehensive set of Management Information Base (MIB) extensions and MIB
II, the IEEE 802.1D bridge MIB, and four Remote Monitoring (RMON) groups, which this IOS software
release supports. You can configure these groups by using an SNMP application or by using the CLI.
The four supported groups are alarms, events, history, and statistics.
This section describes how to access MIB objects to configure and manage your switch. It provides this
information:
• Using File Transfer Protocol (FTP) to access the MIB files
• Using SNMP to access the MIB variables
In a cluster configuration, the command switch manages communication between the SNMP
management station and all switches in the cluster. For information about managing cluster switches
through SNMP, see the “Using SNMP to Manage Switch Clusters” sectiononpage5-24.
When configuring your switch by using SNMP, note that certain combinations of port features create
configuration conflicts. For more information, see the “Avoiding Configuration Conflicts” section on
page 14-1.
SNMP Versions
This software release supports these SNMP versions:
• SNMPv1—The Simple Network Management Protocol, a Full Internet Standard, defined in RFC
1157.
• SNMPv2C, which has these features:
–
SNMPv2—Version 2 of the Simple Network Management Protocol, a Draft Internet Standard,
defined in RFCs 1902 through 1907.
–
SNMPv2C—The Community-based Administrative Framework for SNMPv2, an Experimental
Internet Protocol defined in RFC 1901.
SNMPv2C replaces the Party-based Administrative and Security Framework of SNMPv2Classic with
the Community-based Administrative Framework of SNMPv2C while retaining the bulk retrieval and
improved error handling of SNMPv2Classic.
Both SNMPv1 and SNMPv2C use a community-based form of security. The community of managers
able to access the agent’s MIB is defined by an IP address access control list and password. SNMPv2C
includes a bulk retrieval mechanism and more detailed error message reporting to management stations.
