802.1q

802.1q

An IEEE standard for providing VLAN identification and quality of service (QoS) levels. Four bytes are added to an Ethernet frame, increasing the maximum frame size from 1518 to 1522 bytes. Three bits are used to allow eight priority levels (QoS) and 12 bits are used to identify up to 4096 VLANs. See virtual LAN.

IEEE 802.11ak provides protocols, procedures, and managed objects that enhance the ability of IEEE 802.11 media to provide internal connections as transit links within IEEE 802.1Q bridged networks, and wireless connectivity for fixed, portable, and moving stations within a local area.
Port and Tag based VLAN support for up to 1024 VLANs (802.1Q)
- Onboard 802.1Q VLAN Tagged Ethernet Screening Allows users to assign multiple subnets to each server and isolate devices within each VLAN from the rest of the network for better traffic control and security - Advanced Network Management Supports advanced features such as 802.3x Flow Control, Jumbo Frames and SNMP for network management and can easily interoperate with current networking equipment.
- MSSID and VLAN Support Supports up to eight BSSIDs with 802.1q VLAN tagging enabling users to provide employees and guests with access to the Internet while controlling access to network connected resources to protect sensitive data or resources.
It supports Ethernet virtual connections for IEEE 802.1Q VLAN tagging, 802.1ad or "QinQ," Resilient Ethernet Protocol, 802.3ad Link Aggregation Bundles, Layer 2 Protocol Tunneling (L2PT), and Ethernet over MPLS (EoMPLS), among other features.
2.: the switch port connected to the physical server machine is configured as 802.1Q VLAN trunk and the ports connected to the individual workplace networks are configured to pass only single VLAN.
* Fixed managed versions with a configuration EEPROM tailored to the application's requirements for the unimanaged switches including features such as 802.lp priority and port-based priority, port-based VLAN or IEEE 802.1q VLAN IDs.
IEEE 802.1q virtual LAN (VLAN) management, including double VLAN tagging and VLAN tunneling, supports network security and segmentation.
The integration of the switches, which support Packet 802.1Q, and the USR805453A Professional access point, which supports multiple Virtual APs, enables a single network to transport VLANs efficiently.
