The Switch Load display (see Figure 1-18) provides you with an approximation of the current traffic load across the backplane. The Supervisor Engine III Switch Load display has a vertical orientation but functions the same as the Switch Load display in Supervisor Engines I, II, II G, and III G. The Supervisor Engine Switch Load display indicates the current aggregate traffic load across all buses.
The console port allows you to perform the following functions:
The console port is a data communications equipment (DCE) DB-25 receptacle, which supports a DCE EIA/TIA-232 interface.
|
Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a standard by the Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA). |
|
Note The auxiliary (AUX) port is currently not supported. |
The console port is an EIA/TIA-232 asynchronous, serial, full-featured data terminal equipment (DTE) connection with hardware flow control and an RJ-45 connector. A console port accessory kit with the necessary cabling and adapters is provided for making your terminal connection.
For detailed information on using this port, see the "Connecting a Terminal to the Console Port" section.
|
Note The RSFC is an optional feature of the Supervisor Engine II G and Supervisor Engine III G. |
The RSFC console port is an EIA/TIA-232 asynchronous, serial, full-featured data terminal equipment (DTE) connection with hardware flow control and an RJ-45 connector. A console port accessory kit with the necessary cabling and adapters is provided for making your terminal connection.
The RSFC console port allows you to configure your Catalyst 5000 family RSFC
(if present) for multiprotocol routing using IOS software.
To install the RSFC, see the "Installing the RSFC" section. To configure the RSFC, refer to the Layer 3 Services Software Configuration Guide for your switch.
The console port mode switch allows you to connect a terminal to the supervisor engine using a Catalyst 5000 family Supervisor Engine III console cable.
|
Note The cable and adapters shipped with the switch are the same ones used on the Cisco 2500 series routers (and other Cisco products). |
You also can connect a modem to the console port using the cable and adapter provided with the switch.
Use the console port mode switch as follows:
For more information on using the console port, see the "Connecting a Terminal to the Console Port" section.
The Flash PC card slots are for additional system Flash memory. You can use Flash memory to store and run IOS images or to serve as an I/O device.
For detailed information on using the Flash PC cards, see the "Installing Flash PC Cards (Supervisor Engine III)" section. For detailed information on configuring the supervisor engine to boot from Flash memory, refer to the Software Configuration Guide for your switch.
Supervisor engine Fast Ethernet ports operate in full- or half-duplex mode. The connector and physical media type depends on the supervisor engine model. These connector and cable types are available:
The Gigabit Ethernet ports operate in full-duplex mode only. These ports support the 1000BASE-SX MMF and 1000BASE-LX/LH MMF and SMF interfaces, using SC connectors with multimode fiber-optic cabling.
Supervisor Engine III G has Gigabit Ethernet ports that you can configure with GBICs. See the "Connecting Gigabit Ethernet Modules" section for more information.
For detailed information on using these ports, see the "Connecting 100BASE-FX, 1000BASE-SX, and 1000BASE-LX/LH (Single-Mode or Multimode Fiber-Optic) Connectors" section.
The Catalyst 5000 family switch architecture is based on high-speed switching network principles, using a queuing model for input. Each switch port maintains its own frame buffer memory. Each frame is stored in a frame buffer before it is forwarded to the next port.
Bus arbitration and hardware-based switching are shared among all ports. These features control the destination of packet transfers and access to the data switching bus. The switch uses central bus arbitration and address recognition logic for all modules. Multiple copies are not required for high-speed broadcast and multicast frame forwarding because all ports simultaneously receive the same copy of the frame when it is sent on the backplane.
The Catalyst 5500 series switches feature a 3.6-Gbps backplane; the Catalyst 5000 switch and Catalyst 5002 switch feature a 1.2-Gbps backplane. The Catalyst 5000 family media-independent backplanes support a three-level priority-request scheme. Two priorities are user-selected, and the third is backplane-based.
Buses allow each port to perform a local flush and maintain a packet retry mechanism for outbound port congestion.
Hardware-based switching learns source MAC addresses and VLAN and port information automatically, saves them in a RAM address table, and uses these learned entries to forward packets to their destination addresses.
Supervisor Engine III is available with the NFFC or NFFC II daughter cards, which accommodate all the core-switching logic and allow you to perform Multilayer Switching (MLS) and other Layer 3 functions.
Supervisor Engine II G and III G have an onboard NFFC II chipset, allowing them to perform the same Layer 3 functions as the Supervisor Engine III.
The Supervisor Engine II G and III G are available with the RSFC, an optional daughter card that performs multiprotocol interVLAN routing using Cisco IOS software.
The Catalyst 5000 family switches have the following features:
All modules (including the supervisor engine if you have redundant supervisor engines), fans, and dual power supplies support hot swapping. Hot swapping allows you to add, replace, or remove modules without interrupting the system power or causing other software or interfaces to shut down.
The supervisor engine enables switching and controls data across the switch backplane. Therefore, one supervisor engine must be present for the system to operate, or if redundant, one must be active for the system to operate during hot swapping.
When you remove or insert a switching module, the system does the following:
1. Scans the backplane for configuration changes.
2. Initializes all newly inserted switching modules, notes any removed interfaces, and places them in the administratively shutdown state.
3. Places any previously configured interfaces on the switching module back to the state they were in when they were removed. The system puts any newly inserted interfaces in the administratively shutdown state, as if they were present (but unconfigured) at boot time. If you reinsert a similar switching module into a slot, its ports are configured and brought online up to the port count of the original switching module.
The system runs diagnostic tests on any new interface. If the tests pass, the system is operating normally. If the new switching module is faulty, the system resumes normal operation but leaves the new interfaces disabled. If the diagnostic tests fail and the system fails, remove and replace the switching module.
 |
Caution To avoid erroneous failure messages, allow at least 15 seconds for the system to reinitialize. Note the current configuration of all interfaces before you remove or insert another switching module. |
Environmental-monitoring functions constantly monitor the internal temperature of the chassis and the power supply voltage levels. These monitoring functions allow you to retrieve and display the present values of measured parameters and to display alarms on the console if any of the monitored parameters exceed defined thresholds.
Three status levels indicate the condition of the system:
The processor monitors the temperature inside the module compartment, and the power supplies use the normal and critical status levels to monitor power supply voltages. If the power supply temperature exceeds a defined threshold, the power supply turns off.
|
Note For temperature and voltage thresholds for the processor-monitored levels, refer to the Catalyst 5000 Family Installation Guide. |
The processor uses the normal and alarm status levels to monitor the air temperature in the module compartment. Sensors on the supervisor engine monitor the temperature of the cooling air that flows through the module compartment. If the air temperature exceeds a defined threshold, the system processor indicates an alarm condition using the supervisor engine System Status LED, SNMP traps, and CLI displays. The processor stores the current alarm configuration for both the temperature and DC voltage in nonvolatile random-access memory (NVRAM). You can retrieve information about these alarms as a report of the last shutdown parameters.
|
Note For complete environmental and power specifications, refer to the Catalyst 5000 Family Installation Guide. |
The Catalyst 5000 family switches support different combinations of network switching modules with different maximum port densities. Refer to the Catalyst 5000 Family Module Installation Guide for detailed module functionality.
Each interface (or port) in the switch is designated by two types of addresses: physical and MAC-layer.
The physical interface address is the actual physical location (slot and port) of the interface connector within the chassis. The system software uses the physical interface addresses to control activity within the switch and to display status information. Physical interface addresses are not used by other devices in the network; they are specific to the individual switch and its internal components and software.
The MAC-layer address is a standardized data-link layer address that is required for every port or device that connects to a network. Other devices in the network use these addresses to locate specific ports in the network and to create and update routing tables and data structures. The switches assign and control the MAC-layer addresses on their interfaces.
The supervisor engines use the following onboard memory:
Refer to the Catalyst 5000 Family Release Notes for the minimum memory requirements for each supervisor engine.
|
Note Throughout this publication, the term PC card is used in place of the term PCMCIA Card. |
The Supervisor Engine III supports a Flash file system. You can use a variety of commands to manage the file system (such as cd, pwd, dir, delete, and copy). The file system includes the following devices:
For detailed information on the Flash PC cards, see the "Installing Flash PC Cards (Supervisor Engine III)" section. For detailed information on configuring the supervisor engine to boot from Flash PC card memory, refer to the Software Configuration Guide for your switch.
An electronically erasable programmable read-only memory (EEPROM) component on the supervisor engine stores module-specific information, such as the module serial number, part number, controller type, hardware revision, configuration information, and other details unique to each module. The supervisor engine EEPROM also contains an address allocator, which is a bank of 1024 hardware or MAC-layer addresses, one for each possible VLAN in the system.
You can install redundant supervisor engines in your switch if the following conditions are met:
For more information on configuring supervisor engines for redundant operation, refer to the Software Configuration Guide for your switch.
