# Class CIM_VLANStatistics
extends CIM_StatisticalData

Performance metrics for a either a VLAN or a port (endpoint). Depending on the switch's ability to collect statistics, these statistics may be associated with all endpoints on the port (i.e. port level stats) or they may be per VLAN per port stats. When a port (endpoint) is configured as an access port then port stats are equivalent to the VLAN stats. The AssociatedStatisticalData association is used to tie the VLAN Network (NetworkVLAN)with its statistics.

### Local Class Properties

Name | Data Type | Default Value | Qualifiers
--- | --- | --- | ---
Name | Data Type | Value
VLANId | uint16 |
Description | string | A 12-bit VLAN ID used in the VLAN Tag header.
MappingStrings | string | MIB.IETF|Q-BRIDGE-MIB.VlanId
MaxValue | sint64 | 4094
MinValue | sint64 | 1
VLANPortInFrameDiscards | uint64 |
Counter | boolean | true
Description | string | The number of valid frames received by this port from its segment which were classified as belonging to this VLAN which were discarded due to VLAN related reasons. Specifically, the IEEE 802.1Q counters for Discard Inbound and Discard on Ingress Filtering - RFC2674.
MappingStrings | string | MIB.IETF|Q-BRIDGE-MIB. Dot1qTpVlanPortHCInDiscards
VLANPortInFrames | uint64 |
Counter | boolean | true
Description | string | The number of valid frames received by this ProtocolEndpoint from its segment which were classified as belonging to this VLAN. Note that a frame received on this port is counted by this object if and only if it is for a protocol being processed by the local forwarding process for this VLAN. This object includes received bridge management frames classified as belonging to this VLAN (e.g. GMRP, but not GVRP or STP - RFC2674).
MappingStrings | string | MIB.IETF|Q-BRIDGE-MIB.Dot1qTpVlanPortHCInFrames
VLANPortOutFrames | uint64 |
Counter | boolean | true
Description | string | The number of valid frames transmitted by this port to its segment from the local forwarding process for this VLAN. This includes bridge management frames originated by this device which are classified as belonging to this VLAN (e.g. GMRP, but not GVRP or STP - RFC2674).
