This chapter provides information on the following procedures:
Using SNMP, the FastHub communicates with the third-party network-management application through its in-band management interface (the SNMP agent). The management information used to configure and monitor a FastHub are represented as objects in a database called a MIB. The FastHub can be managed in-band through any SNMP-compatible workstation or through Telnet. The FastHub supports standard MIB-II objects, RFC 1516 repeater MIB objects, as well as custom extensions found in the enterprise-specific MIB. The extensions provide access to unique FastHub features and other management functions.
In general, you use SNMP network-management applications to locate the FastHub icon and access the table of FastHub objects. You can then view the characteristics and counters describing the FastHub and set object values as defined in the FastHub-supported MIBs.
CiscoWorks applications, one method of SNMP network management, are integrated on several SNMP-based network management platforms, including SunNet Manager, HP Open View, and IBM NetView. Contact your authorized Cisco sales representative for detailed information on CiscoWorks.
The complete set of FastHub MIB objects are listed by function (user action) in the "Standard MIBs and MIB Extensions" section in this chapter. These MIB objects and other SNMP-based management techniques are described in detail in a separate manual, the FastHub 300 Series MIB Reference Manual, available only on the Cisco Connection Documentation, CiscoPro Solutions CD, previously called the Cisco UniverCD. To order the Cisco Connection Documentation, CiscoPro Solutions CD in North America, contact your local reseller; international customers, contact your local Cisco sales office. The CD is available both as a single CD and as an annual subscription. You can also access CiscoPro product documentation on the World Wide Web URL http://www.cisco.com.
Before beginning any in-band management, the FastHub must be configured for SNMP management. To do this, assign an IP address to the FastHub by using the IP Configuration menu described in the "IP Configuration Menu" section in the "Out-of-Band Management" chapter.
You can use any Telnet TCP/IP package to access the management console. The FastHub supports up to seven simultaneous Telnet sessions. The Telnet package must support VT-100 terminal emulation. See the "Out-of-Band Management" chapter for details on using the management console.
The FastHub must be configured with an IP address before you can use in-band management. You can assign an individual address to each FastHub, or you can use the BOOTP/DHCP protocol to maintain a centralized database of these addresses.
You need a host machine with a BOOTP/DHCP server program to use BOOTP/DHCP. A database containing a list of physical MAC addresses and corresponding IP addresses must be set up on this host. Other information, such as the corresponding subnet masks, default gateway addresses, and host names, can also be stored in the database, but this information is optional. The FastHub must be able to access the BOOTP/DHCP server through one of its ports.
After a system reset, the FastHub searches its nonvolatile random-access memory (NVRAM) for a configured IP address, and if it exists, then searches for a default gateway address and an IP subnet mask.
If an IP address has not been configured, the FastHub transmits a BOOTP/DHCP request to all physically connected ports, requesting a mapping for the port's physical MAC address. A valid response includes the IP address, which is mandatory, along with the subnet mask, the default gateway, and the host name, which are optional.
The reception of a valid BOOTP/DHCP response immediately activates the rest of the system's protocol suite, without requiring a system reset. The information is also saved in the NVRAM, so the next reset does not have to use BOOTP/DHCP.
For more information about using BOOTP/DHCP, see the BOOTP/DHCP server documentation.
This section lists the actions you use to configure and manage a FastHub and the MIB objects associated with each action. A complete description of the objects, their defaults, and possible values is included in the FastHub 300 Series MIB Reference Manual, available on CD-ROM only.
The following are the seven supported MIBs:

A trap client is a management workstation configured to receive and process traps. The FastHub supports up to four trap clients with separate community strings. At least one trap client must be defined before any traps are generated. See the section "SNMP Management Menu" in the "Out-of-Band Management" chapter for instructions on defining trap clients.
The FastHub generates the traps described in the following sections.
A user is repeatedly trying to log on to the management console using an invalid password. You can define the number of invalid passwords permitted before this trap is generated. The FastHub can shut down the management console following the generation of this trap.
The FastHub issues this trap when its power-on self-test (POST) does not pass all tests. However, note that some failures are catastrophic, preventing the generation of this trap.
An RPS is connected to the FastHub but a failure exists in the power system.
This trap is issued when the NMM is unable to complete its DHCPDISCOVER/DHCPREQUEST process, when it fails to extend the lease for the current address, or when it accepts an address change from the user.
This trap conveys information related to the operational status of the FastHub. This trap is sent either when the value of rptrOperStatus changes or when a nondisruptive test completes.
This trap is sent when a change occurs in the group structure of the FastHub. This occurs only when a group is logically or physically removed from or added to a repeater.
This trap conveys information related to the operational status of the FastHub. This trap is sent on completion of a reset action (such as an SNMP Set on the rptrReset object).
This SNMP trap is generated when an alarm entry crosses its rising threshold and generates an event that is configured for sending SNMP traps.
This SNMP trap is generated when an alarm entry crosses its falling threshold and generates an event that is configured for sending SNMP traps.
Generated when the repeater is reset or after the completion of a firmware upgrade.
Generated upon a power-up reset.
This trap is currently not generated by the FastHub.
This trap is currently not generated by the FastHub.
Generated when the FastHub receives an SNMP message that is not accompanied by a valid community string.
