Contains the VLAN statistics data.
The statistics collected represent a distribution based
on the IEEE 802.1Q VLAN-ID (VID), for each good frame
attributed to the data source for the collection.
This function applies the same rules for attributing frames
to VLAN-based collections. RMON VLAN statistics are collected
after the Ingress Rules defined in section 3.13 of the VLAN
Specification [20] are applied.
It is possible that entries in this table will be
garbage-collected, based on agent resources, and VLAN
configuration. Agents are encouraged to support all 4094
index values and not garbage collect this table.
