Management Options

The EdgeIron 2402CF and EdgeIron 4802CF contain a comprehensive array of LEDs for at-aglance monitoring of network and port status. It also includes a built-in network management agent that allows the switch to be managed in-band using SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web browser, or remotely via Telnet. The switch provides an RS-232 serial port (DB-9 connector) on the front panel for out-of-band management. A PC may be connected to this port for configuration and monitoring out-of band via a null-modem cable. (See "Cables" on page 13-1 for wiring options.) These switches provide a wide range of advanced performance-enhancing features. Port-based and tagged VLANs, plus support for automatic GVRP VLAN registration and IGMP multicast filtering provide traffic security and efficient use of network bandwidth. CoS priority queueing ensures the minimum delay for moving real-time multimedia data across the network. Flow control eliminates the loss of packets due to bottlenecks caused by port saturation. Broadcast storm control prevents broadcast traffic storms from engulfing the network. For a detailed description of the switches' advanced features, refer to the Foundry EdgeIron User Guide.

Description of Hardware

10BASE-T/100BASE-TX Ports
These are dual-speed RJ-45 ports. Because all ports on this switch support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. (See 1000BASE-T Pin Assignments on page 13-5.) Each of these ports support auto-negotiation, so the optimum transmission mode (half or full duplex), and data rate (10 or 100 Mbps) can be selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually. Each port also supports IEEE 802.3x auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated.
These are combination Gigabit RJ-45 ports that are shared with Small Form Factor Pluggable (SFP) transceiver slots. If an SFP transceiver (purchased separately) is installed in a slot and has a valid link on the port, the associated RJ-45 port is disabled. The 1000BASE-T RJ-45 ports support automatic MDI/MDI-X operation, so you can use straightthrough cables for all network connections to PCs or servers, or to other switches or hubs. (See 1000BASE-T Pin Assignments on page 13-5.)

Operational Concepts

EdgeIron 24GS or 48GS switches can be stacked together as described later in this section. The stack functions as an integral system for easy management through a common interface. It provides robust and reliable operation through a centralized stacking topology in which one unit in the stack acts as the Master for configuration tasks and firmware upgrade. All of the other units function in Slave mode, but can automatically take over management of the stack if the Master unit fails. For management purposes, the stack functions as single integrated system. The Master Unit represents the whole stack for all of the normal configuration tasks, and can be accessed through any port (on any switch in the stack) that is assigned to the management VLAN. This allows you to use a single IP address to manage every unit in the stack. The Master unit processes each management request and forwards information on the required task to the slave units for completion. The EdgeIron 24GS or 48GS have two fixed stacking ports on the rear panel (i.e., one uplink port and one downlink port). Each stacking port operates up to 10 Gbps each way in full duplex mode, supporting a bandwidth of up to 20 Gbps, or a total stacking bandwidth of up to 40 Gbps when traffic is flowing between two different source-destination pairs on each of the stacking ports. Note however that overhead will have an impact on the throughput. EdgeIron 24GS or EdgeIron 48GS can be stacked together, but the number of units you can have in a stack depends on whether or not a 10GBASE module is installed in the units. Table 26.1 and Table 26.2 show the number of units permitted in a stack. If no optional 10GBASE modules are installed on the units, then you can stack up to eight 24GS or eight 48GS units.

Number of 10GBASE modules in a Stack 0 0
Permitted 24GS Yes Yes Yes Yes Yes Yes Yes Yes 48GS Yes Yes Yes Yes Yes Yes Yes Yes
However, if you install a 10GBASE module in the units, you can have up to eight 24GS in a stack, but only six 48GS in a stack.

Functionalities

2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port. 3. Connect one end of the cable to the LC or SC port on the switch and the other end to the port on the other device. Since LC and SC connectors are keyed, the cable can be attached in only one orientation. Figure 10-3. Making Fiber Port Connections
As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid.
10 Gbps Fiber Optic Connections
An optional 10 Gigabit transceiver (Xenpak or XFP) can be used for a backbone connection between switches. Warning: This switch uses lasers to transmit signals over fiber optic cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on. 1. Remove and keep the ports protective cover. When not connected to a fiber cable, the cover should be replaced to protect the optics. 2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port. 3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.
4. As a connection is made, check the Link LED on the module to be sure that the connection is valid.
Chapter 11 Managing the Device
This chapter describes how to enter and configure login parameters, and use the Command Line Interface (CLI) including how to configure basic, non-protocol features on EdgeIron devices. More detailed information can be found in the EdgeIron User Guide.

Accessing the CLI

When accessing the management interface for the switch over a direct connection to the servers console port, or via a Telnet connection, the switch can be managed by entering command keywords and parameters at the prompt. Using the switchs command-line interface (CLI) is very similar to entering commands on a UNIX system.
Connecting to the Console Port
The DB-9 serial port on the switchs front panel is used to connect to the switch for out-of-band console configuration. The command-line configuration program can be accessed from a terminal or a PC running a terminal emulation program. A null-modem console cable is provided with the switch. Attach a VT100-compatible terminal, or a PC running a terminal emulation program to the switch. You can use the console cable provided with the package, or use a null-modem cable that is compatible with the following console pin assignments. Figure 11-1. Serial Port (DB-9 DTE) Pin-Out

Console#copy running-config startup-config Startup configuration file name []: startup Console#
Enabling SNMP Management Access
The switch can be configured to accept management commands from Simple Network Management Protocol (SNMP) applications such as SMC EliteView. You can configure the switch to (1) respond to SNMP requests or (2) generate SNMP traps. When SNMP management stations send requests to the switch (either to return information or to set a parameter), the switch provides the requested data or sets the specified parameter. The switch can also be configured to send information to SNMP managers (without being requested by the managers) through trap messages, which inform the manager that certain events have occurred. The switch includes an SNMP agent that supports SNMP version 1, 2c, and 3 clients. To provide management access for version 1 or 2c clients, you must specify a community string. The switch provides a default MIB View (i.e., an SNMPv3 construct) for the default public community string that provides read access to the entire MIB tree, and a default view for the private community string that provides read/write access to the entire MIB tree. However, you may assign new views to version 1 or 2c community strings that suit your specific security requirements. Community Strings (for SNMP version 1 and 2c clients) Community strings are used to control management access to SNMP version 1 and 2c stations, as well as to authorize SNMP stations to receive trap messages from the switch. You therefore need to assign community strings to specified users, and set the access level.
11-Foundry Networks, Inc. May 2002
The default strings are: public - with read-only access. Authorized management stations are only able to retrieve MIB objects. private - with read-write access. Authorized management stations are able to both retrieve and modify MIB objects.
To prevent unauthorized access to the switch via SNMP version 1 or 2c clients, it is recommended that you change the default community strings. To configure a community string, complete the following steps: 1. From the Privileged Exec level global configuration mode prompt, type snmp-server community string mode, where string is the community access string and mode is rw (read/write) or ro (read only). Press <Enter>. (Note that the default mode is read only.) 2. To remove an existing string, simply type no snmp-server community string, where string is the community access string to remove. Press <Enter>.

Cables

Twisted-Pair Cable and Pin Assignments
For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards. Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation. Figure B-1 illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins. Figure 13-1. RJ-45 Connector Pin Numbers
100BASE-TX/10BASE-T Pin Assignments

Because all ports on this switch support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3 and 6 at the other end of the cable. The table below shows the 10BASE-T/100BASE-TX MDI and MDI-X port pinouts.
