Color planes Mouse * The larger your IP network or the more HP OpenView Windows (ovw) sessions you run, the more memory you will need. A good guideline is 10 megabytes for every additional 500 nodes, or 25 megabytes of memory for every additional ovw session that you expect to run.
This ensures speed and accuracy of map generation. All HP 9000 Systems (manager stations or hosts) that are running HP-UX version 10.20 or HP-UX version 11.00 should also be running the HP OpenView SNMP Agent software as part of their networking software.

If you want to remove Network Node Manager, see the HP OpenView Network Node Manager Products Installation Guide. To remove products for HP-UX 10.20 or 11.00, use the HP System Administration Manager.
When using Hub & Switch Management, you can do the following: use HP OpenView functions to automatically discover and display the IP map (and submaps). HP hubs, bridges, and switches that are set up for SNMP/IP operation will be displayed as appropriate “connector” devices.
HP OpenView Network Management Platform HP OpenView Network Management Platform HP OpenView is a “platform” for network management applications. As a platform, it allows multiple network management applications that are OpenView compliant—such as HP Hub & Switch Management—to share platform functionality and a common display.
Internet Protocol (IP). The network management station used to run Hub & Switch Management is referred to as an SNMP manager system. HP devices with SNMP agents are called agent systems. Each network management operation requested by the manager system is executed by one or more agent systems.
What HP Devices Can Be Managed What HP Devices Can Be Managed For device management, HP Hub & Switch Management provides a Device View for most managed HP devices. You can display a Device View using your browser if this feature is supported for the device.

The port number. The port may be appended with one of the following: • Trkx - The port trunk to which this port belongs • Mesh - The port has been assigned to a switch mesh domain • MP - The port is a Monitor Port Port Type The MAC layer type, for example, 100VG or FDDI.
Port” that you can use with a network analyzer to monitor other ports on the switch. For the HP J3298A and HP J3299A you can only choose the Monitoring port and the port to be monitored. For other switches you can choose to have all the ports for one VLAN monitored, or you can select individual ports to be monitored.
Page 57
Switches are also a more cost-effective solution. You can create virtual LANs by assigning selected ports of your HP switch to a VLAN.
For example, if User A sends out a broadcast message to connect to its server, the request is sent out of all ports on the switch. When the server responds to User A, the switch intercepts the response and learns that the server is on that port.
Page 59
MAC address of a node that corresponds to the network layer address. When Broadcast Control is enabled, the switch intercepts the ARP packet on its way to the destination node. If this destination is unknown to the switch, the switch floods the ARP request to all ports. When the destination port responds, the switch stores information about the source and destination MAC addresses and layer 3 addresses in its ARP cache.
A set of queriers and hosts that send and receive data from the same set of sources is a multicast group. The HP switches have a standards-based IGMP implementation. The switches process IGMP packets by learning which of the switch’s interfaces are linked to hosts that are members of multicast groups and multicast routers.
Forward with High Priority When “Forward with High Priority” is checked, any IGMP packets received by the switch will be forwarded in a prioritized manner, preceding packets with normal priority. The Spanning Tree Protocol The Spanning Tree Protocol (IEEE 802.1d) maintains a loop-free topology in networks with redundant bridges or switches.

Setting Up Security for a Device Device Passwords Figure 8-1. Assign Passwords to a Device There are two categories of passwords: Operator (Read only): The Operator can view all pages except the Security pages. For switches, this password is the same as the console password. Manager (Full Read and Write permissions): The Manager can view all pages and make any changes in any page.
Manager passwords, which protect access to the browser interface and console settings. To set a Community Name for a device: Right mouse click on a device symbol and select SNMP Configure HP Hub/Switch Enter the passwords in the Set SNMP Passwords (Communities) page.
Setting Up Security for a Device Port Security (hubs only) Port Security (hubs only) You can assign security levels on hubs port by port. Select the Port Security button to view the current settings for each port. This feature is not available for switches.
Eavesdrop Prevention Eavesdrop Prevention is a feature of several HP devices that stops a computer or other device from seeing network traffic that is not intended for that port. When Eavesdrop Prevention is configured on a port, the port’s authorized MAC address is compared with the destination address of any outbound packets.
Note: In order for traps to function, you must also set the trap in the Thresholds dialog box, as follows: Using the right mouse button, click on the device symbol in the HP Network Node Manager map. Select SNMP Configuration.
Setting Up Security for a Device Set Security Policy for Selected Ports (hubs only) port will not be disabled when a new address is learned if the setting is Continuous. Set Security Policy for Selected Ports (hubs only) You can set the security policy port by port, or by selecting a group of ports. Select one port by clicking on the entry in the Port Security page.

Setting Up Security for a Device The Intrusion Log (hubs only) Intruder Address - Address of the intruder. The IP address is displayed for SNMP agent violations. The MAC address is displayed for port violations. The port violation must be cleared before another port violation will display.
Performing Diagnostics Using HP Hub & Switch Management, you can help isolate faults by running device self-tests, Link tests, and Ping tests (IP networks). Note: For older HP devices that cannot be managed with a Web browser, read the chapter “Management for Non-Browserable Devices”...
Performing Diagnostics Rebooting a Device Figure 9-1. Ping/Link Test The number of successes or failures of the test packets reaching the Destination IP or MAC Address are displayed at the top of the page. A failure means that either the device at the destination address did not respond within the timeout specified, or the data returned from the device indicated an error.
Performing Diagnostics Resetting a Hub to Factory Default Settings Resetting a Hub to Factory Default Settings Resetting the hub to the factory default settings removes any configuration changes that you have made since installing the device, and restores the factory defaults. The IP address is also removed; you must enter an IP address before the device will operate on your network, unless you have Bootp or DHCP.

Use the online help for more information about specific device functions. About Closeup Views HP Hub & Switch Management provides direct access to HP hub, bridge, and switch management for devices that are not manageable with a Web browser through graphical control panels, or Closeup Views. If you have switching hubs, you can also use the Closeup View to create and modify segments in your network.
From an HP OpenView map, use the left mouse button and double-click on a hub, bridge, or switch symbol. On an HP OpenView map, select a hub, bridge, or switch symbol. Then display the Monitor menu and select HP Hub/Switch.
The number of Closeup Views that you can display at one time depends on your free system resources available (such as available memory). If the HP device can be managed with your browser, the menu option SNMP Configure HP Hub/Switch will also display when you right-mouse-click on a device symbol.
Overview of Toolbar Functions HP Hub & Switch Management device functions in the Closeup Views allow you to configure, monitor and manage HP hubs, bridges, and switches. The following table summarizes the Toolbar menu functions in the Closeup Views.
