Q: From the Automatic Configuration Management screen (Policies - Configuration Policies - Security), when trying to delete the community named "public" on the Security Policy page, why is the warning "removing public could cause device communication problems" displayed?
Deleting the community named "public" disables many network management functions such as Discovery, Traffic Monitoring, and Threshold Settings. If security for network management is a concern, it is recommended that you change the write access for the "public" community to "restricted".

Legacy Device Management Information
The device you selected can only be managed from
the HP Toptools for Hubs & Toptools Management Workstation
To obtain generic SNMP information about this device, select:
"Properties" from the Action menu on the Devices screen
To try and establish a telnet session to this device, select:

Q: What is an HP Toptools for Hubs & Toptools server? HP Toptools for Hubs & Toptools client? What are the differences?
The user installs and executes HP Toptools for Hubs & Toptools and its applications (such as HP Toptools for Hubs & Toptools for Hubs & Switches) on the HP Toptools for Hubs & Toptools server. The user may access the user interface on the server or, optionally, on a remote client running the Microsoft Internet Explorer Web browser (version 5.0 or greater) or Netscape Communicator 4.51 or greater. The only restrictions to using a remote client are that the user cannot access the Closeup View for certain older devices (see the list of devices that support the web browser interface) and the user cannot access the HP Toptools for Hubs & Download Manager for updating device software. Closeup View and HP Toptools for Hubs & Download Manager are available on the server.

Q: The Security LEDs on my devices light up after I install HP Toptools for Hubs & Toptools for Hubs & Switches. What's wrong?
Using HP Toptools for Hubs & Web JetAdmin on your network along with HP Toptools for Hubs & Toptools for Hubs & Switches will cause the security LED on network devices to light. This happens because HP Toptools for Hubs & Web JetAdmin tries to access network devices using a nonstandard community name, "internal". This community name conflicts with those already known to HP Toptools for Hubs & Toptools. HP Toptools for Hubs & Web JetAdmin does not otherwise affect the operation of your network devices.

Q: HP Toptools for Hubs & Toptools for Hubs & Switches runs progressively slower over time. What's wrong?
There are two possibilities:
- Running your web browser without interruption over time consumes virtual memory. Left unattended for a long enough period, it may slow the operation of HP Toptools for Hubs & Toptools and other applications running on that computer. To free up the lost virtual memory, close the browser window every couple days and re-invoke it, then bring up HP Toptools for Hubs & Toptools.
- Your Alert Log may be overloaded. Having too many alerts in the alert database can slow down CPU performance. Follow the instructions above in the FAQ "How do I clear the Alert Log Database?".

Q: My network does not have a DNS server, and the browser appears to hang. What's wrong?
If your network does not have a DNS server, there is a wait of at least 4 minutes when you attempt to access a device through the web browser interface; the browser will appear to hang. Thereafter, performance remains sluggish. If you do have a DNS server, this is not a problem. To workaround this issue, add the IP address and alias of every device you want to manage to the file "drivers/etc/hosts". This file must be edited on every PC from which net management will be done through the web browser interface.

Q: When I request a new map view, go to a segment view, or do a Locate from Traffic Monitor or the current map, I get an error message that I cannot connect to the server. What's wrong?
When you try to perform these actions, and if you have an incorrect version of the "vbajet32.dll" file in "\winnt\system32\", you will get an error message stating that you cannot connect to the server. The version of this file commonly found on computers which causes this issue is 5.0.7122. The correct version to use with HP Toptools for Hubs & Toptools is 3.0.6908, and is included on the HP Toptools for Hubs & Toptools for Hubs & Switches CD-ROM, and normally is installed unless the version on your system is read-only and you choose during installation not to overwrite it. To resolve the issue, copy the version of "vbajet32.dll" from the "\Toptools\HP Toptools for Hubs &wnd\system\" directory to your "\winnt\system32\" directory.

Q: How do I configure trap receivers for the HP Toptools for Hubs & Advancestack 10Base-T Switching Hubs and HP Toptools for Hubs & ProCurve 12- and 24-Port 10Base-T Hubs that I manage via my Web browser?
You cannot configure this SNMP information from the Web Browser user interface nor from the console. To access the SNMP configuration screen for these devices, perform the following steps:
| | 1. | Select the device from the appropriate topology map: |
| | |
• | For HP Toptools for Hubs & Advancestack Assistant for Windows: HP Toptools for Hubs & ASA Topology View |
| | • | For HP Toptools for Hubs & Advancestack Assistant for Openview NNM/NT: NNM Topology Map |
| | • | For HP Toptools for Hubs & Toptools for Hubs & Switches: Maps |
| | 2. | Right mouse click to bring up the popup menu. |
| | 3. | Select the SNMP menu item: |
| | |
• | For HP Toptools for Hubs & Advancestack Assistant for Windows: 'SNMP Config' |
| | • | For HP Toptools for Hubs & Advancestack Assistant for Openview NNM/NT: 'SNMP Configure Hub/Bridge' or use the menu selection 'Monitor->SNMP Configuration' |
| | • | For HP Toptools for Hubs & Toptools for Hubs & Switches: 'SNMP/TRAP Configuration...' |
| | 4. | The "Device Configuration" window will then appear. This window has the following areas, or tabs, for SNMP configuration: Thresholds, Trap Receivers, Community Names, & Authorized Managers. |

Q: Are RMON and RMON2 supported in HP Toptools for Hubs & Toptools?
RMON is supported, but RMON2 is not supported. HP Toptools for Hubs & Toptools does have the ability to manipulate set RMON thresholds in HP Toptools for Hubs & ProCurve devices and receive RMON events generated by those devices. It does not utilize the RMON2 functionality available in the HP Toptools for Hubs & ProCurve Switch 4108gl.
HP Toptools for Hubs & Toptools also utilizes the HP Toptools for Hubs & Extended RMON functionality to provide the Traffic Monitor feature (which provides TopN functionality similar to RMON groups 5 and 6) and NPA reporting.

|
|
Q: What are the differences between RMON, RMON2, and HP Toptools for Hubs & Extended RMON (XRMON)?
Each of these is a specification that is supported (primarily) by devices.
| | • | RMON is made up of 10 groups or functions. Most managed HP Toptools for Hubs & ProCurve devices support RMON by specifically supporting: |
| | |
• | group 1 (statistics) |
| | • | group 2 (history) |
| | • | group 3 (alarms) |
| | • | group 9 (events) |
| | • | RMON2 adds 9 more groups. The HP Toptools for Hubs & ProCurve Switch 4108gl supports the RMON groups listed above and adds group 19 (probeConfig) from RMON2. |
| | • | HP Toptools for Hubs & Extended RMON is a proprietary specification that defines a method for statistical sampling of network traffic in order to provide traffic analysis. With XRMON, HP Toptools for Hubs & has a solution to provide network-wide traffic analysis with very low overhead on network resources. |

Q: What happens if the HP Toptools for Hubs & Toptools "traffic data collector settings" is set to "manual" and you either do not add any device to be monitored or you add one device but do not select any of its ports for collection of HP Toptools for Hubs & extended RMON data?
You will receive a message in the NT application event log called "TrafficCD". You can ignore this message because the traffic collector will still collect the HP Toptools for Hubs & extended RMON data. The message does not indicate a problem with the configuration of the traffic data collector.
