Configuring VSDs

Use the VSD Add/Modify window to add or modify a VLAN Secure Domain (VSD). 

Adding a VSD

Procedure:

Step Action
1 In the VSD Add/Modify window, enter a name for the VSD, for example, math_dept.   A name can be composed of up to 32 ASCII-printable characters, except a question mark (?), must not include spaces, and must contain at least one alphabetic character. The name assigned must be unique.  You cannot create another VSD on the same module using the same name.

Assigning a name to a VSD is optional.

2 Enter a VNbus tag number. If you do not want to specify a tag number, you can specify none or leave the field blank.  The VNbus tag is a unique number used to link two or more VSDs, each of which is physically located on a different module in the same hub.  Assigning the same VNbus tag number to the VSDs effectively links the individual VSDs (on different modules) into a single, larger VSD.  The value can be any number from 66 through 128.  To connect VSDs on different hub modules, assign the same VNbus tag number to each.

For example, if you want to make VSD 3 on a VNswitch 900 AE module and VSD 2 on a VNswitch 900EE module members of the same VSD, assign the same VNbus tag number (66, for example) to both VSDs.

3

Enter a list of bridge ports you want to assign to the VSD. You can list the ports individually by separating each with a comma (for example, 1,2,3,4,5) or you can enter a range of ports by separating the first and last port numbers in the range with a hyphen (for example, 1-5). You can also combine a list of individual entries with a range of entries (for example, 1-4, 6,7). Spaces are not permitted between port numbers and the comma or a hyphen.

Assigning a port list is optional. If you do not want to assign a port list, you can specify none or leave the field blank.

Modifying a VSD

Procedure:

Step Action
1 To change the VSD name, in the VSD Add/Modify window, enter  a new name for the VSD, for example, math_dept.   A name can be composed of up to 32 ASCII-printable characters, except a question mark (?), must not include spaces, and must contain at least one alphabetic character. The name assigned must be unique.  You cannot create another VSD on the same module using the same name.

Assigning a name to a VSD is optional.

2 To change the VNbus tag number, enter a new number in the VNbus tag field.  If you do not want to specify a tag number, you can specify none or leave the field blank.

The VNbus tag is a unique number used to link two or more VSDs, each of which is physically located on a different module in the same hub.  Assigning the same VNbus tag number to the VSDs effectively links the individual VSDs (on different modules) into a single, larger VSD.  The value can be any number from 66 through 128.  To connect VSDs on different hub modules, assign the same VNbus tag number to each.

To change the bridge ports assigned to the VSD, enter the port numbers in the Ports field.  You can list the ports individually by separating each with a comma (for example, 1,2,3,4,5) or you can enter a range of ports by separating the first and last port numbers in the range with a hyphen (for example, 1-5). You can also combine a list of individual entries with a range of entries (for example, 1-4, 6,7). Spaces are not permitted between port numbers and the comma or a hyphen. 

Assigning a port list is optional. If you do not want to assign a port list, you can specify none or leave the field blank.
