NetBIOS Access Filters Example
The show lnm config command displays the logical configuration of this bridge, including all the pertinent information for configuring this router into LNM:
Wayfarer# show lnm config
Bridge(s) currently configured:
From | ring | 001, address 0000.0028.abcd |
Across bridge | 001 | |
To | ring | 008, address 4000.0028.abcd |
From | ring | 002, address 0000.3000.abc4 |
Across bridge | 002 | |
To | ring | 008, address 4000.3000.abc4 |
From | ring | 003, address 0000.3000.5735 |
Across bridge | 003 | |
To | ring | 008, address 4000.3000.5735 |
In this example, six station definitions must be entered at the LNM Station, one for each of the MAC addresses listed in this sample show lnm config display.
NetBIOS Access Filters Example
The following command permits packets that include the station name ABCD to pass through the router, but denies passage to packets that do not include the station name ABCD:
netbios
The following command specifies a prefix where the pattern matches any name beginning with the characters DEFG. Note that the string DEFG itself is included in this condition.
netbios
The following command permits any station name with the letter W as the first character and the letter Y as the third character in the name. The second and fourth letters in the name can be any character. This example would allow stations named WXYZ and WAYB; however, stations named WY and WXY would not be included in this statement, because the question mark must match some specific character in the name.
netbios
The following command illustrates how to combine wildcard characters:
netbios
The command specifies that the marketing list deny any name beginning with AC that is at least three characters in length (the question mark would match any third character). The string ACBD and ACB would match, but the string AC would not.
The following command removes the entire marketing NetBIOS access list.
no netbios
To remove single entries from the list, use a command such as the following:
no netbios
This example removes only the list that filters station names with the letters AC at the beginning of the name.
