Using the Console Interface Using Password Security Using Password Security There are two levels of console access: Manager and Operator. For security, you can set a password on each of these levels. Level Actions Permitted Manager: Access to all console interface areas. This is the default level. (That is, if a Manager password has not been set prior to starting the current console session, then anyone having access to the console can access any area of the console interface.)
Using the Console Interface Using Password Security N o t e If there is only a Manager password set (with no Operator password), and the Manager password is not entered correctly when the console session begins, the switch operates on the Operator level. If there are both a Manager password and an Operator password, but neither is entered correctly, access to the console will be denied.
Using the Console Interface Using Password Security b. Type a password of up to 16 characters and press [Enter]. (Remember that passwords are case-sensitive.) When prompted with Enter new password again, retype the new password and press [Enter]. d. To set another password, return to step 2a. Otherwise, go to step 3. Select Return to Main Menu to exit from the Set Password screen.
Using the Console Interface Rebooting the Switch Rebooting the Switch Rebooting the switch terminates the current console session and performs a reset of the operating system. Some of the reasons for performing a reboot include: Activating certain configuration changes that require a reboot Activating port modules that have been changed since the last reboot.

However, you must reboot the switch in order to implement any changes to any parameters in the following areas: IPX Service Internet (IP) Service Serial Link...
Using the Console Interface Resetting the Switch Resetting the Switch Resetting requires physical access to the front of the Switch 2000. There are two levels of reset: Hardware reset: Momentarily interrupts switch operation and performs a complete hardware self-test. This also clears the Event Log. Configuration reset: This is a drastic action that interrupts switch operation, clears any passwords, clears the event log, performs a com- plete self-test, and reboots the switch in its factory default configuration.
Configuring the Switch Overview This chapter provides an overview of the Switch 2000 configuration features. In its factory default configuration, the Switch 2000 automatically operates as a multiport learning bridge with network connectivity provided by the particular modules that you have installed. However, to “fine-tune” your switch for the specific performance and security needs in your network, you may choose to reconfigure certain switch parameters.
Configuring the Switch Overview N o t e In the factory default configuration, the Spanning Tree Protocol (STP) is off. However, if the topology of your network includes any redundant loops between switches or bridges, you should enable STP. See “Spanning Tree” (page 3-17).

Advanced Concepts Overview The switch provides support for these advanced features: Spanning Tree Protocol—STP (page 7-2) Port trunking (page 7-5) Filtering for enhanced bandwidth usage and in-band security (page 7-8) Virtual LANs—VLANs (page 7-14) IP Multicast—IGMP (page 7-23) Automatic Broadcast Control—ABC (page 7-30)
Advanced Concepts Spanning Tree Protocol (STP) Spanning Tree Protocol (STP) The switch uses the IEEE 802.1d Spanning Tree Protocol (STP) to ensure that only one path at a time is active between any two nodes on the network. In networks where there is more than one physical path between any two nodes, STP ensures a single active path between them by blocking all redundant paths.
Advanced Concepts Spanning Tree Protocol (STP) How To Configure Spanning Tree: In most cases, the default STP param- eter settings are adequate. In cases where it is not, use this procedure to make configuration changes. C a u t i o n If you enable STP (step 5), it is recommended that you leave the remainder of the STP parameter settings at their default values until you have had an opportunity to evaluate STP performance in your network.
Advanced Concepts Spanning Tree Protocol (STP) If the remaining STP parameter settings are adequate for your network, go to step 9. Use [Tab] or the arrow keys to select the next parameter you want to change, then type in the new value. (If you need information on STP parameters, press [Enter] to select the Actions line, then press H to get help.) Repeat step 7 for each additional parameter you want to change.
FDDI Module.) On the B-version of the Switch 2000 (J3100B) and on the Switch 800T, you can implement up to six port trunks in a switch, which enables the switch to function as a high-speed backbone. (The A-version of the Switch 2000—J3100A—allows only one port trunk, but can...
Advanced Concepts Port Trunking N o t e Using more than one media type and/or link speed in a port trunk is not supported. The console interface allows only links of the same media type within the same trunk. Similarly, it is recommended that all links in the same trunk have the same speed.
Advanced Concepts Port Trunking Trunk Assignment Figure 7-4. Example of Configuring a Port Trunk To assign another port to the trunk, repeat steps 3c, and 3d. When you are finished assigning ports to the trunk, press [Enter], then [S] (for Save) to save the new port trunk configuration and return to the Configuration menu.
Advanced Concepts Filters and Security Filters and Security To enhance the switch’s bandwidth usage and in-band security, configure per- port filters to forward desired traffic or drop unwanted traffic, as described below. The switch can support up to 50 filters. Table 7-1.
Advanced Concepts Filters and Security Protocol Filters. This filter type enables the switch to restrict traffic of a particular protocol type to a specific destination port or ports on the switch (or to be dropped for all ports on the switch). Filtered protocol types include: IP (Ethernet) IP (802.3 SAP) DEC LAT...
Advanced Concepts Filters and Security N o t e If a node designated by the Source MAC parameter is moved to a different port than its original source port, any traffic to or from that node will not be forwarded by the switch. Forwarding will resume if the node is moved back to the original source port.

Advanced Concepts Virtual LANs (VLANs) Virtual LANs (VLANs) The switch supports port-based virtual LANs (VLANs). A VLAN is a collection of ports that belong to a single broadcast domain. (That is, all ports carrying traffic for a particular subnet address would belong to the same VLAN.) This allows workgroups to be defined on the basis of their logical function instead of their physical location, and does not require recabling.
Advanced Concepts Virtual LANs (VLANs) Effect of VLANs on Other Switch Features IPX and IP Interfaces. There is a one-to-one relationship between a VLAN and an IP or IPX network interface. Since the VLAN is defined by a group of ports, the state (up/down) of those ports determines the state of the IP or IPX network interface associated with that VLAN.
Advanced Concepts Virtual LANs (VLANs) Adding a Switch 2000 Module. If you install a Switch 2000 module in a previously unoccupied slot, the ports in the module will be automatically added to the default VLAN. (To properly install a Switch 2000 module, refer to the documentation you received with the module.) Interswitch Link for VLAN A...
Advanced Concepts Virtual LANs (VLANs) If you are managing VLANs with SNMP in an IPX network, configure the IPX gateway encapsulation and gateway node. (An IPX node address is automatically assigned to each VLAN interface.) Refer to “IPX Service Features'' on page 3-7. How To Configure a VLAN In the factory default configuration, all ports on the Switch 2000 belong to a physical broadcast domain named “DEFAULT_VLAN”.

To assign a port on the switch to a different VLAN than the current selection: Press [E] (for Edit) to move the highlight to the VLAN column.
DECnet Currently, the problem of duplicate MAC addresses in IPX and IP Host- Only environments is addressed through the HP router OS version described below. However, for XNS and DECnet environments, a satis- factory solution is not available from any vendor at this time.
HP Router 470 (formerly Router LR) HP Router 480 (formerly Router BR) HP Router 650 Release A.09.70 (or later) is available electronically through the HP BBS service and the World Wide Web. Refer to the “Customer Support Services” card at the beginning of this manual.
Advanced Concepts IP Multicast (IGMP) IP Multicast (IGMP) In a network where IP multicast traffic is transmitted for various multimedia applications, you can use the switch to reduce unnecessary bandwidth usage on a per-port basis by configuring IGMP. How IGMP Operates The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP) suite.
Advanced Concepts IP Multicast (IGMP) Once the switch learns the port location of the hosts belonging to any partic- ular multicast group, it can direct group traffic to only those ports, resulting in bandwidth savings on ports where group members do not reside. The following example illustrates this operation.
Advanced Concepts IP Multicast (IGMP) The next figure (7-14) shows a network running IP multicasting using IGMP without a multicast router. In this case, the IGMP-configured switch runs as a querier. PCs 2, 5, and 6 are members of the same IP multicast group. IGMP is configured on switches 3 and 4.
Advanced Concepts IP Multicast (IGMP) N o t e IP multicast addresses occur in the range from 126.96.36.199 through 188.8.131.52. When IGMP is enabled, any Traffic/Security filters (page 7-8) configured with a “Multicast” filter type and a “Multicast Address” within the above range are disabled and an event log message indicating this action is logged .
Advanced Concepts IP Multicast (IGMP) N o t e If you move a port from one VLAN to another, that port will retain its IP multicast (IP Mcast) parameter setting. For example, suppose port A1 is in DEFAULT_VLAN with an IP Mcast setting of “Blocked”. If you create another VLAN named VLAN2 and then move port A1 to VLAN2, the IP Mcast setting will remain the same (Blocked).
Advanced Concepts IP Multicast (IGMP) Figure 7-16. Example of the (Default) IP Multicast (IGMP) Service Screen Press the Space bar to select Yes (to enable IGMP). Use [v] to highlight the Forward with High Priority parameter. If you want IGMP traffic to be forwarded with a higher priority than other traffic on the switch or VLAN, use the Space bar to select Yes.
Advanced Concepts IP Multicast (IGMP) Changing the Querier Configuration Setting.. The Querier feature, by default, is enabled and in most cases should be left in this setting. If you need to change the querier setting, you can do so using the IGMP Configuration MIB.
Advanced Concepts Automatic Broadcast Control (ABC) Automatic Broadcast Control (ABC) ABC helps to conserve bandwidth and processing power for IP and/or IPX traffic within a broadcast domain without adding the levels of cost and latency normally associated with routers. ABC achieves this by using the switch to reduce IP ARP and RIP broadcast traffic and IPX NSQ, RIP, and SAP broadcast traffic normally found on a network.
Advanced Concepts Automatic Broadcast Control (ABC) To learn host D’s MAC address, host A sends a broadcast ARP request. Because the switch does not yet know the location of host D, it floods the request out all ports. However, the switch also learns from the ARP request the location of host A and stores this information in its ARP cache.
Advanced Concepts Automatic Broadcast Control (ABC) Reducing RIP and SAP Broadcast Traffic. You can also configure ABC to limit IP RIP and IPX RIP and SAP broadcasts, which can further reduce broadcast traffic on your network. RIP and SAP broadcasts are normally forwarded on all ports.
Advanced Concepts Automatic Broadcast Control (ABC) Activates a broadcast limit for either all ports in the switch or, if VLANs are configured, for all ports in the selected VLAN. (You can accept the default broadcast limit setting, change it, or turn it off.) Enabling Both IP and IPX (IP_IPX) Enabling ABC for IP and IPX causes the switch to: Send a proxy IP ARP reply for hosts whose addresses the switch has...

File Transfers Overview You can download new switch software (operating system—OS) and upload or download switch configuration files. These features are useful for acquiring periodic switch software upgrades and for storing or retrieving a switch configuration.
Downloading an Operating System Downloading an Operating System You can use the switch console’s TFTP feature (Download OS), HP’s SNMP Download Manager, or the HP Update Utility (update.exe) to download a new operating system (OS) to the switch. Downloading a new OS does not change the current switch configuration.
This procedure assumes that an OS file for the switch has previously been stored on a TFTP server accessible to the switch. (The OS file is typically available from HP’s electronic services—refer to the card at the front of this manual.) Before you use the procedure, do the following: Determine the IP or IPX address of the TFTP server in which the OS file has been stored.
File Transfers Downloading an Operating System (upper or lower) that you specify for the filename in the Switch 2000 Download OS screen is the same case as the characters in the OS filenames in the TFTP server. In the Main Menu, select Download OS. You will then see this screen: This line appears only if VLANs are configured.
File Transfers Downloading an Operating System Example of a TFTP Server Address Example of a Remote File Name on a TFTP Server Figure 8-2. Example of the Download OS Screen During a Download A “progress” bar indicates the progress of the download. When the entire operating system has been received, all activity on the switch halts and the following message appears: WRITING SYSTEM SOFTWARE TO FLASH, BACK SOON...
If you have two or more Switch 800Ts and/or the B-version of the Switch 2000 (HP J3100B) networked together, you can download the OS software from one switch to another by using the Download OS feature in the switch console interface.
File Transfers Troubleshooting TFTP Downloads Troubleshooting TFTP Downloads If a TFTP download fails, the Download OS screen indicates the failure. Message Indicating TFTP Download Failure Figure 8-3. Example of Message for Download Failure To find more information on the cause of a download failure, examine the messages in the switch’s Event Log.
File Transfers Troubleshooting TFTP Downloads For a Unix TFTP server, the file permissions for the OS file do not allow the file to be copied. Another console session (through either a direct connection to a terminal device or through Telnet) was already running when you started the session in which the download was attempted.
File Transfers Transferring Switch 2000 Configurations Transferring Switch 2000 Configurations You can use the following commands to transfer Switch 2000 configurations between the switch and a PC or Unix workstation. Command Function Download a Switch 2000 configuration file from a networked PC or Unix workstation using TFTP.

BOOTP Operation Overview Bootp is used to download configuration data from a Bootp server to the switch or to a VLAN configured on the switch. Either a minimal IP configura- tion or a full configuration can be retrieved from the Bootp server. N o t e The Switch 2000 supports only the DHCP (Dynamic Host Configuration Protocol) implementations that are backwards compatible with Bootp.
If you have multiple switches that will be using Bootp to get their IP configuration, you should use a unique symbolic name for each switch. is the “hardware type” . For the HP AdvanceStack Switch 2000, set this to ether (for Ethernet). This tag must precede the ha tag .
BOOTP Operation Configuring Bootp Configuring Bootp In its default configuration, the switch is configured for Bootp operation. However, if an IP address has previously been configured or if the IP Config parameter has been set to Disabled, then you will need to use this procedure to reconfigure the parameter to enable Bootp operation.
MAC Address Management Overview The Switch 2000 assigns MAC addresses in the following three areas: Default MAC address assigned at the factory Automatically assigned MAC address(es) corresponding to any VLANs you configure in the switch The Spanning Tree Protocol (STP) uses either the default MAC address for the switch or, if VLANs are configured, the MAC addresses automati- cally assigned to the VLANs.
MAC Address Management Switch (Default) MAC Address Switch (Default) MAC Address A default MAC address is assigned to each Switch 2000 at the factory. This address is on the label below the Console RS-232 port (shown below): Label Showing Default MAC Address Figure F-1.
MAC Address Management VLAN MAC Addresses VLAN MAC Addresses If you add VLANs to the Switch 2000, each VLAN is automatically assigned a different MAC address. All ports in a particular VLAN will have the same MAC address. To determine the MAC address assigned to a particular VLAN, display the port data for any port assigned to that VLAN.
MAC Address Management MAC Addresses (for Spanning Tree Operation) MAC Addresses (for Spanning Tree Operation) When no VLANs are configured, STP uses the MAC address assigned to the switch. (This is the MAC address printed on the label on the front of the switch.) When VLANs are configured, STP must be configured separately for each VLAN.
