5. Use Table 12-1 to configure the VLAN parameters:
6. Click APPLY to create the new VLAN, or CANCEL to restore previous settings.
Configuring VLAN Parameters
To configure all ports assigned to a VLAN:
1. In the Switching Parameters section of the Web Agent window, click Virtual
LANs. The VLAN Configuration dialog box opens.
2. Click on the Name of the VLAN whose members you want to view. The VLAN
Switch Ports dialog box opens.
3. Use Table 12-2 to configure the VLAN parameters:
Table 12-1. VLAN Parameters
Parameter Definition
Name Name assigned to this VLAN.
ID Identifier used throughout the network to identify this VLAN. If
you want ports on more than one device to participate in a
particular VLAN, you must use the same VLAN ID to identify the
VLAN on every device.
Initial Hash Table
Size Sets the number of Layer 2 address entries used to store
information for this VLAN. Use the default value.
The general implementation rule is: Use a smaller size when you
implement lots of VLANs (more than 50). Use a larger size when
you have lots of MAC addresses on the same VLAN in the
network (more than 16,000).
Note: The number of address for a given hash table is 4:1 (for
example, if you have a hash table of 16 bytes, the VLAN can hold
64 addresses in it’s table instance.
Auto Increment
HT Size Determines whether the number of memory “buckets” used by
this VLAN’s address table adjusts automatically when memory
use become inefficient. Select true if you want the HT size to
increase when the number of entries belonging to this VLAN
reaches a pre-defined threshold. Select false to disable this
feature.

Parameter Defines...
Port The VLAN switch port.
Port Name The user-assigned name for this port.
