Release Notes
Hot Extraction /Unit Failure/Stacking Cable Disconnection or Failure
Failure of a unit, hot extraction of a unit, or any stacking link failure causes a

VLAN Supported Features

VLANs are collections of switching ports that comprise a single broadcast domain.
Packets are classified as belonging to a VLAN based on either the VLAN tag or
based on a combination of the ingress port and packet contents. Packets sharing
common attributes can be grouped in the same VLAN.
Port Based Virtual LANs (VLANs)
Port-based VLANs classify incoming packets to VLANs based on their ingress
port.
Full 802.1Q VLAN Tagging Compliance
IEEE 802. 1 Q defines an architecture for virtual bridged LANs, the services provided in
VLANs and the protocols and algorithms involved in the provision of these services.
Protocol Based VLAN
VLAN classification rules are defined on data-link layer (Layer 2) protocol identification.
Protocol based VLANs are used for isolating Layer 2 traffic for differing Layer 3 protocols.
GVRP Support GARP
VLAN Registration Protocol (GVRP) provides IEEE 802. 1 Q-compliant VLAN pruning and
dynamic VLAN creation on 802. 1 Q trunk ports. When GVRP is enabled, the device
registers and propagates VLAN membership on all ports that are part of the active
underlying "Spanning Tree Protocol Features" topology.
Private VLAN Edge
A port can be defined as a Private VLAN Edge port of an uplink port, so that it will be
isolated from other ports.
