This chapter describes how to use Telnet or SNMP to access the FastHub through a workstation and configure the FastHub for SNMP management using the Bootstrap Protocol/Dynamic Host Control Protocol (BOOTP/DHCP). The chapter lists the actions for managing and configuring a FastHub, the Management Information Base (MIB) objects associated with each action, and the traps generated by the BMM.
Using SNMP, the BMM communicates with a third-party network-management application through its in-band management interface (the SNMP agent). The BMM can be managed in-band through any SNMP-compatible workstation or through Telnet.
You can use any Telnet TCP/IP package to access the management console. The BMM supports up to seven simultaneous Telnet sessions. The Telnet package must support VT100 terminal emulation. See the "Out-of-Band Management" chapter for details on using the management console.
Before beginning any in-band management, you must configure the BMM for SNMP management by assigning an IP address to the BMM. You can assign an individual IP address to each BMM or use the BOOTP/DHCP protocol to maintain a centralized database of these addresses. To assign an individual IP address to a BMM, use the IP Configuration menu described in the "IP Configuration Menu" section in the "Out-of-Band Management" chapter.
To assign an IP address to a BMM using BOOTP/DHCP protocol, set up a database containing a list of physical MAC addresses and corresponding IP addresses on a host machine with a BOOTP/DHCP server program. You can store other information in the database, such as the corresponding subnet masks, default gateway addresses, and host names, but this information is optional. The BMM must be able to access the BOOTP/DHCP server through a BMM port.
After a system reset, the BMM searches its nonvolatile random-access memory (NVRAM) for a configured BMM IP address. If one exists, the BMM then searches for a default gateway address and an IP subnet mask.
If a BMM IP address has not been configured, the BMM transmits a BOOTP/DHCP request to all physically connected ports, requesting a mapping for each 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 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.
In general, you use SNMP network-management applications to locate the FastHub icon and access the table of BMM objects. You can then view the characteristics and counters describing the BMM and set object values as defined in the BMM-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 BMM 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 the software code comments of each MIB.
This section lists the actions you use to configure and manage a BMM and the MIB objects associated with each action. The following MIBs are supported:

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.
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.
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 BMM can shut down the management console following the generation of this trap.
The BMM 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.
A redundant power source is connected to the BMM, but a failure exists in the power system.
This trap is issued when the BMM supervisor 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 is issued when broadcast storm control is enabled and the number of broadcast packets per second received from a port is higher than the broadcast threshold. Use the object mrBridgeBroadcastStormAlert to enable or suppress the generation of this trap.
This trap is issued when a bridge becomes the new spanning-tree root. The trap occurs at the end of the time period provided by the Topology Change Timer.
This trap is issued when a bridge port transitions from learning mode to forwarding mode, or from forwarding mode to blocking mode. The trap is not issued if a newRoot trap is issued for the same transition.
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.
