This chapter describes IBM's configuring and monitoring of NetBIOS over bridged networks and over DLSw networks. It includes the following topics:
NetBIOS configuration commands are available at the ASRT/DLSW config> prompt. Changes you make to the router's configuration are not effective immediately. They become part of the router's configuration memory when you restart it. This chapter refers to configuration changes as permanent.
NetBIOS monitoring commands are available at the ASRT/DLSW>prompt. Monitoring commands take effect immediately, but are not saved in the router's non-volatile configuration memory. Thus, while monitoring commands allow you to make real-time changes to the router's configuration, these changes are temporary. The router's configuration memory overwrites them when the router restarts. This chapter refers to changes you make at the monitoring prompt as static.
You can display the NetBIOS config> prompt from either the ASRT configuration environment or the DLSw configuration environment. Changes you make at the NetBIOS config> prompt affect both bridging and DLSw.
| Note: | The NetBIOS configuration commands are not effective immediately. You must restart or reload the device before they become effective. |
To display the NetBIOS config> prompt from the ASRT configuration environment:
Config>protocol asrt Adaptive Source Routing Transparent Bridge user configuration ASRT config>NetBIOS NetBIOS Support User Configuration NetBIOS config>
To display the NetBIOS config> prompt from the DLSw configuration environment:
Config>protocol dls DLSw protocol user configuration DLSw config>NetBIOS NetBIOS Support User Configuration NetBIOS config>
You can display the NetBIOS> prompt from either the ASRT monitoring environment or the DLSw monitoring environment.
Changes you make at the NetBIOS> monitoring prompt affect both bridging and DLSw.
To display the NetBIOS> monitoring prompt from the ASRT monitoring environment:
+ protocol asrt ASRT>NetBIOS NetBIOS Support User Console NetBIOS>
To display the NetBIOS> prompt from the DLSw monitoring environment:
+ protocol dls DLSw>NetBIOS NetBIOS Support User Console NetBIOS>
If you are sending NetBIOS traffic over DLSw, use this procedure at the DLSw config> prompt:
Open NetBIOS SAPs on both sides of the link to enable DLSw to transmit NetBIOS frames.
DLSw config> open-sap Interface # [0]? Enter SAP in hex(range 0-F0),'SNA', or 'NB'[4]? nb SAP F0 opened on interface 0
You can prioritize SNA and NetBIOS traffic to prevent one type of session from using up too much of the available bandwidth during network congestion. To do so, enter priority to set a priority for SNA sessions and NetBIOS sessions. You also set a message allocation that corresponds to a session's priority.
Use the set priority command as shown in the following example:
DLSw config> set priority Default priority for SNA DLSw session traffic (C/H/M/L) [M]? C Default priority for NetBIOS DLSw session traffic (C/H/M/L) [M]? L Default priority for SNA DLSw explorer traffic (C/H/M/L) [M]? H Default priority for NetBIOS DLSw explorer traffic (C/H/M/L) [M]? M Message allocation by C/H/M/L priority (4 digits) [4/3/2/1]? Maximum NetBIOS frame size (516, 1470, 2052, or 4399) [2052]? 516
The default message allocation of 4/3/2/1, provides the following allocation to sessions:
The router uses the priority and message allocation to selectively limit the burst length of specific types of traffic. For example:
and
the router processes four SNA frames before it processes two NetBIOS frames. Once the router processes two NetBIOS frames, it processes four SNA frames, and so on.
In this scenario, the router dedicates two-thirds of available bandwidth to SNA traffic (a ratio of 4 to 2). Note that the router counts frames, rather than bytes, when allocating bandwidth according to the priorities you assign.
You can change the message allocation for sessions from the default of 4/3/2/1. You must always enter four digits, from 9 to 1, in descending order. For example, if the SNA priority is Critical and the NetBIOS traffic is Medium, and you change the message allocation to 8/7/6/5, the router processes eight SNA frames before it processes six NetBIOS frames.
You can also use the DLSw set priority command to change the maximum NetBIOS frame size. The default is 2052. Set this parameter to the largest frame size you expect to need, and no larger. Setting the frame size larger than needed reduces the number of available buffers.
Use the DLSw set memory command to set the number of bytes the router allocates as a buffer for NetBIOS UI frames. If the TCP transmit buffer becomes full, the router uses this buffer for NetBIOS UI frames.
Note that the number of bytes allocated for NetBIOS is global, and not per session.
DLSw config> set memory Number of bytes to allocate for DLSw (at least 26368) [141056]? Number of bytes to allocate per LLC session [8192]? Number of bytes to allocate per SDLC session [4096]? Number of bytes to allocate for NetBIOS UI-frames [40960]?
Table 12 lists the NetBIOS configuration and monitoring
commands.

The NetBIOS configuration (Talk 6) commands are not effective immediately. They remain pending until you issue the reload or restart command.
Adds a new name cache entry to the router's permanent or static configuration, or adds a NetBIOS name list entry used to limit remote station access to local DLSWs. You can add name cache entries for DLSw neighbors only. The router ignores entries that you add for ASRT traffic.
Syntax:
The router prompts you for the 16th character in hex only if you have indicated via set cache-parms that 16 characters are relevant in a NetBIOS name.
Multiple entries with different IP addresses may be added for a single NetBIOS name. This allows the name to be accessed through multiple DLSw neighbors.
| Note: | The NetBIOS name is case sensitive and must match the case of the network NetBIOS name. |
Example: add cache-entry
Enter up to 15 characters of NetBIOS name (no wild cards) Enter NetBIOS name[]? Accounting Enter last character of NetBIOS name in hex [0]? 01 Enter IP Address [0.0.0.0]? 20.2.1.3 Name cache entry has been created
From the configuration prompt, adds a permanent name list entry. The change does not take effect until the router is restarted or the change is committed from the NetBIOS> prompt using set name-list command.
From the monitoring prompt, adds a temporary name list entry. The change does not take effect until the change is committed from the NetBIOS> prompt using set name-list command. The change is lost when you restart the router.
The NetBIOS name qualifier represents one or more NetBIOS names reachable on this router's locally bridged network that are to be made reachable to other routers through DLSw.
The NetBIOS name qualifier may contain the following two types of wildcard characters:
Notes:
Example: add name-list
Enter up to 16 characters of NetBIOS name qualifier (wild cards OK). Enter name qualifier []? NY_SERV* NetBIOS name qualifier type (I=individual, G=group) [I]? Name list entry has been created For the new entry to take effect, restart or commit the change using 't 5' : 'SET NAME-LIST'.
Deletes name cache entries or NetBIOS name list entries.
Syntax:
From the configuration prompt, deletes name cache entries from the router's permanent configuration. The router prompts for a record number, which is the number of the entry you want to delete. To see a list of entry numbers, enter list cache all.
From the monitoring prompt, deletes name cache entries from the router's static configuration or active cache. The router prompts for a cache entry name. To see a list of entries, enter list cache conf or list cache active.
| Note: | The NetBIOS name is case sensitive. |
Example for Configuration: delete cache-entry
Enter name cache record number [1]? 2
Name cache entry has been deleted
Example for Monitoring: delete cache-entry
Enter up to 15 characters of NetBIOS name (no wild cards)
Enter NetBIOS name []? ADMIN
Name cache entry NOT found in Active list for name entered
Name cache entry has NOT been deleted from Active list
Static name cache entry deleted from Config list
From the configuration prompt, deletes a permanent name list entry. The router prompts for a record number that is the number of the entry you want to delete. To see a list of entry numbers, enter the list name-list all command. The change does not take effect until the router is restarted or the change is committed from the monitoring prompt using the set name-list command.
From the monitoring prompt, temporarily deletes a name list entry. The router prompts for a record number that is the number of the entry you want to delete. To see a list of entry numbers, enter the list name-list config command. The change does not take effect until the change is committed from the monitoring prompt using the set name-list command. The change is lost if the router is restarted.
Example: delete name-list
Enter name list record number [1]? 1 Name list entry NY_SERV* / INDIVIDUAL has been deleted. For the deletion to take effect, restart or commit the change using 't 5' : 'SET NAME-LIST'.
Disables duplicate frame filtering, use of NetBIOS name lists, or route caching.

Sets name caching parameters, turns frame type filtering on or off for either bridging or DLSw, adjusts duplicate frame filtering timers and frame retry timers, and sets NetBIOS name list parameters. Also displays the NetBIOS name and byte filtering prompt.
Syntax:
Example: set cache-parms
Significant characters in name [15]? Best path aging timeout value in seconds [60.0]? Reduced search timeout value in seconds [1.5]? Unreferenced entry timeout value in minutes [5000]? Max nbr local name cache entries [500]? Max nbr remote name cache entries [100]? Cache parameters set
The default is 15.
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.
The default is 60 seconds. The range is 1.0 to 100000.0 seconds.
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. The router forwards the duplicate frame to both bridges and DLS. DLS broadcasts the corresponding SSP message to all possible DLS partners.
The default is 1.5 seconds. The range is 1.0 to 100.0 seconds.
The default is 5000 minutes. The range is 1 to 100 000 minutes.
The default is 500. The range is 100 to 30 000. You can lower this value to save router memory. To optimize memory usage, processor usage, and the amount of broadcast traffic, set the number of local name cache entries as close as possible to the total number of NetBIOS stations (servers and clients) that are active on this router's local bridge network.
The default is 100. The range is 100 to 30 000. You can lower this value to save router memory. To optimize memory usage, processor usage, and the amount of broadcast traffic, set the number of remote name cache entries to the number of remote NetBIOS servers that are to be accessed by NetBIOS clients on this router's local bridge network, plus about 25%.
Example: set filters bridge
Filter Name Conflict frames? [No]: y Name conflict filtering is ON Filter General Broadcast frames? [No]: General broadcast filtering is OFF Filter Trace Control frames? [No]: Trace control filtering is OFF
From the NetBIOS > monitoring prompt, displays the NetBIOS filtering monitoring prompt (NetBIOS Filter>). Monitoring NetBIOS filtering is explained in "Monitoring NetBIOS Filtering".
This parameter allows you to access NetBIOS byte filtering.
Example: set filters byte
NetBIOS Filtering configuration NetBIOS Filter config>
Example: set filters dlsw
Filter Name Conflict frames? [Yes]: Name conflict filtering is ON Filter General Broadcast frames? [Yes]: General broadcast filtering is ON Filter Trace Control frames? [Yes]: Trace control filtering is ON
From the NetBIOS > monitoring prompt, displays the NetBIOS filtering monitoring prompt (NetBIOS Filter>). Monitoring NetBIOS filtering is explained in "Monitoring NetBIOS Filtering".
This parameter allows you to access NetBIOS name filtering.
Example: set filters name
NetBIOS Filtering configuration NetBIOS Filter config>
Example: set general
ATTENTION! Setting Duplicate Frame Filter Timeout to zero... disables duplicate frame checking! Duplicate frame filter timeout value in seconds [1.5]? Duplicate frame detect timeout value in seconds [5.0]? General parameters set
If DLSw is enabled, the software also prompts you for:
Command frame retry count [5]? Command frame retry timeout value in seconds [0.5]?
The range is 0.0 to 100.0 seconds. Zero disables duplicate frame checking. The default is 1.5 seconds.
The range is 0.0 to 100.0 seconds. The default is 5 seconds.
Number of duplicate NetBIOS UI frames the target DLSw router sends to its locally attached LAN. These frames are sent at intervals specified by the command frame retry timeout.
The range is 0 to 10. The default is 5.
The range is 0.0 to 10.0 seconds. The default is 0.5 seconds.
From the configuration prompt, permanently sets the local NetBIOS name list parameters. The change does not take effect until either the router is restarted or the change is committed from the monitoring prompt using set name-list command.
From the monitoring prompt, this command temporarily sets the local NetBIOS name list parameters. The command also commits any NetBIOS name list changes that have been made from the configuration or monitoring prompts.
Allows testing of real NetBIOS names against the current NetBIOS cache or the NetBIOS name list.
Syntax:
Example (no corresponding NetBIOS cache entry): test cache ABC
Destination NetBIOS name being tested .... ABC <20> Name cache entry NOT found. How frame destined for this NetBIOS name is forwarded to DLSw partners ..... Send to all partners.
Example (corresponding NetBIOS cache entry): test cache LA_SERV01

This section describes dynamic reconfiguration (DR) as it affects Talk 6 and Talk 5 commands.
NetBIOS does not support the CONFIG (Talk 6) delete interface command.
The GWCON (Talk 5) activate interface command is not applicable for NetBIOS. There are no interface-specific NetBIOS parameters.
The GWCON (Talk 5) reset interface command is not applicable for NetBIOS. There are no interface-specific NetBIOS parameters.
NetBIOS supports the following GWCON commands that temporarily change the operational state of the device. These changes are lost whenever the device is reloaded, restarted, or you execute any dynamically reconfigurable command.
The following commands do not affect any NetBIOS functions already active
at the time of the command unless otherwise noted. The changes do apply
to all subsequent NetBIOS operations and traffic.
