MSTP is used to eliminate loops in a LAN. It is compatible with STP and
RSTP. This document describes:
Introduction to MSTP
Configuring MSTP
LLDP enables a device to maintain and manage its own and its immediate
neighbor's device information, based on which the network management
system detects and determines the conditions of the communications
links. This document describes:
Introduction to LLDP
Performing Basic LLDP Configuration
Configuring CDP Compatibility
Configuring LLDP Trapping
Using the VLAN technology, you can partition a LAN into multiple logical
LANs. This document describes:
Introduction to VLAN
Types of VLAN

Introduction and Configuration of Voice VLAN
GVRP is a GARP application. This document describes:
GARP overview
GVRP configuration
GARP Timers configuration
As defined in IEEE802.1Q, 12 bits are used to identify a VLAN ID, so a
device can support a maximum of 4094 VLANs. The QinQ feature
extends the VLAN space by allowing Ethernet frames to travel across the
service provider network with double VLAN tags. This document
describes:
Introduction to QinQ
Configuring basic QinQ
Configuring Selective QinQ
Configuring the TPID Value in VLAN Tags
BPDU tunneling enables transparently transmission of customer network
BPDU frames over the service provider network. This document
