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 addresses for a given hash table is
approximately 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.
