Disable NetBIOS Duplicate-Filtering

This option disables duplicate frame filtering for bridging.


Disable NetBIOS Name-List

This option permanently disables the use of the name list.


Disable NetBIOS Route Caching

Route caching is the process of converting broadcast frames to specifically routed frames (SRFs) using the entries in the NetBIOS name cache.

This option disables route caching for bridging.


Enable NetBIOS Duplicate-Filtering

This option enables duplicate frame filtering for bridging.


Enable NetBIOS Route Caching

Route caching is the process of converting broadcast frames to specifically routed farems (SRFs) using the NetBIOS name cache.

This option enables route caching for bridging.


Set NetBIOS Cache Parms

This option sets name caching parameters that apply to bridging.

  1. Select the Significant characters in name. This selection determines whether the MSS considers 15 or 16 characters when it looks up the NetBIOS name.

    Default Value: 15

  2. Enter the Best path aging timeout.

    This is the amount of time the router considers the address and route for a name cache entry to be the best path to that station. When this timer expires, the router deletes the name cache entry and attempts to discover a new best path for the NetBIOS name.

    To determine the best path, the router considers transmission time between nodes on all possible routes connecting those nodes, as well as largest frame size. The router does not consider a path suitable if it cannot accommodate the largest NetBIOS frame that could be transmitted over the path.

    Valid Values: 1 to 100000 seconds

    Default Value: 60

  3. Enter a Reduced search timeout.

    When the router receives a Name-Query, Status.Query, or Datagram during the timeout period, it carries out a search based on current NetBIOS name cache information.

    If the router receives a duplicate frame after this timer expires, it assumes the previous route is not longer valid and it widens its search.

    Valid Values: 1.0 to 100.0 seconds

    Default Value: 1.5

  4. Enter a Unreferenced entry timeout value.

    The router keeps a name that is not referenced in its cache for this length of time before deleting it. If the cache fills up, the router removes entries sooner.

    Valid Values: 100 to 100000 minutes

    Default Value: 5000 minutes

  5. Enter a Max number local name cache entries.

    This is the maximum number of locally-learned entries the router saves in the name cache.

    You can lower this value to save router memory. To optimize memory usage, processor usage, and the amount of broadcast traffic, the number of local name cache entries should be set as close as possible to the total number of NetBIOS stations (servers and clients) that are active on this router'slocal bridge network.

    Valid Values: 1 to 30000

    Default Value: 500

  6. Enter the Max nbr remote name cache entries.

    This is the maximum number of remote entries the router saves in the name cache.

    Valid Values: 1 to 30000

    Default Value: 100

    You can lower this value to save router memory.

Select the Submit button.


Set NetBIOS General

This option sets the duplicate frame timeout, command frame entry retry count and timeout.

This option sets duplicate frame timeout, duplicate frame-detect timeout, and the command frame retry count and timeout.

  1. Enter the Duplicate frame filter timeout you want to configure.

    This parameter applies only to bridged traffic if duplicate-filtering is enabled.

    During this timeout period, the router filters all duplicate frames it receives.

    Valid Values: 0.0 to 100.0

    Default Value: 1.5

    Note: A value of 0 disables duplicate frame checking.

  2. Enter the Duplicate frame detect timeout you want to configure.

    This is the amount of time the router saves entries in its duplicate frame filter database. When this timer expires, the router creates new entries for new frames it receives.

    Valid Values: 0.0 to 100.0

    Default Value: 5

Select the Submit button.


Set NetBIOS Bridge Filters

This option sets filtering for bridging on or off.

  1. Click yes to enable Filter Name Conflict frames.

  2. Click yes to enable Filter General Broadcast frames.

  3. Click yes to enable Filter Trace Control frames.

Select the Submit button.


Test NetBIOS Cache

This option tests NetBIOS cache.

Enter the NetBIOS Name.

Valid Values: Any character string up to 15 characters in length

Default Value: none
