Using VLANs, Spanning Tree, and Hunt Groups (Layer 2 and Layer 3)

5.Use Table 12-1 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

Sets the number of Layer 2 address entries used to store

Size

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

Determines whether the number of memory “buckets” used by

HT Size

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.

 

 

6.Click APPLY to create the new VLAN, or CANCEL to restore previous settings.
