How to get mac address table from snmp

Getting MAC addresses using SNMP on EX2300/EX3400

Case in point - today i found a mac address i'd never seen before. I found it. Wasn't hard to do. Simplified SNMPv3 settings window. It is also saved to the history database. Additional switch brands beyond HP and Cisco will now report. Generic switch stack report added to web page report. A new LAG interface section has also been added to the web page reports both for post-mapping and for reviewing a mapping from the history database. The new location is saved in the registry. For single switch mappings the software will then exit.

For switch list mappings it will exit when the list is complete. This overrides any saved or default user database directory locations.

Use SNMP to figure out which port a MAC address is reachable on

If the full path is omitted, it will now save to the Documents directory or the last used 'save' directory. This information has been added to the web browser Switch Mapping Analysis report. It is also saved to the History database for later review. These videos show many typical tasks you might do while mapping a switch or set of switches.

You can now delete a one or more selected devices from the list rather than just one at a time. You can now delete a one or more selected switch groups from the list rather than just one at a time. You can now delete a one or more selected switch groups from the switch list rather than just one at a time. This information appears in the web browser switch mapping analysis report. Now detects if the libeay Update links to obtain libeay Note that libeay It is strange that the 64 bit version does not have 64 in the filename.

IPv6 will be supported in a later release. The hidden option must be used in conjunction with the -postexit option. More improvements to this table are planned for a future release. This button is used to select previously used switches and switch groups. Use it to avoid re-entering switch settings. Changes to the device IP address are now migrated to all database tables.

They are all temporary and are deleted at the end of the session. It also now shows the path, size and attributes of the current history database.

About the Revision History Page

Problem was normally seen while showing MAC addresses. Default is to remove entries older than seconds 1 hour. The columns will be reset to defaults in order to support adding this new column.

This will improve the importing process into spreadsheets. Expanded switch properties gathering for Extreme Networks switches. If ifIndex is not visible a warning is displayed when you start a manual mapping. Any problems importing the list are now specifically detailed, ie.

Problem with reimporting a list fixed. There is a new checkbox in Global Settings that limits these column widths to twice the header text width. The checkbox is enabled by default. They will always be positive or indeterminate. Switch firmware must be v2. This should reduce confusion with 'config' as defined by Cisco. This also extends to Switch Lists - in previous versions Ping Sweep was only done at the beginning of the Switch List execution. Ping Sweep ranges should be chosen to be the active IP ranges handled by the switch.

Ping Sweep now also allows setting of ping packet timeout and retries. Note: on first use of 2. You will need to edit the Ping Sweep range for each switch. Now the user can turn on or off a port on that switch without manually loading the switch settings. Selections labeled 14 days and older were not working correctly.

The switch was mapping correctly and the warning did not need to be shown - it only occurred if VLAN 1 was not used at all. Previously, it was copying the data from the device 2 field to both the device 2 and device 1 fields as it moved the selection up in the list. This made a switch list mapping not work correctly because the device 1 field may not be in the switch configuration list. Also added command line options to turn on Switch List show individual reports, save to XML reports disk and show final report after doing the Switch List from a text list.

Changed 'unknown' to 'not advertised' when LLDP data was not received by the switch. The Supported Capabilities are now correctly parsed.

  7. Changed 'unknown' to 'not advertised' when CDP data was not received by the switch. Some switches may show more ports than they did before, an example is more loopbacks. If there is no alias, the IP is used. This will not affect normal operation, some very old switches may now map. Has anyone be successful in getting this information? If so, what OID did you use?
