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
Isolate-user-vlan configuration
Introduction and Configuration of Voice VLAN
An isolate-user-VLAN adopts a two-tier VLAN structure. In this approach,
two types of VLANs, isolate-user-VLAN and secondary VLAN, are
configured on the same device. This document describes:
Overview
Configuring Isolate-User-VLAN
Displaying and Maintaining Isolate-User-VLAN
A voice VLAN is configured specially for voice traffic. After assigning the
ports connecting to voice devices to a voice VLAN, you can configure
quality of service (QoS) parameters for the voice traffic, thus improving
transmission priority and ensuring voice quality. This document describes:
Overview
Configuring a Voice VLAN
Displaying and Maintaining Voice VLAN
GVRP is a GARP application. This document describes:
GARP/GVRP 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
describes:
Introduction to BPDU Tunneling
Configuring BPDU Tunneling
Port mirroring copies packets passing through a port to another port
connected with a monitoring device for packet analysis to help implement
network monitoring and troubleshooting. This document describes:
