Description
DLDP
In the use of fibers, link errors, namely unidirectional links, are likely to
occur. DLDP is designed to detect such errors. This document introduces
the commands for:
z
Enabling DLDP
z
Setting DLDP Mode
z
Setting the Interval for Sending Advertisement Packets
z
Setting the DelayDown Timer
z
Setting the Port Shutdown Mode
z
Configuring DLDP Authentication
z
Resetting DLDP State
Smart Link
Smart Link is a solution for active-standby link redundancy backup and
rapid transition in dual-uplink networking. This document introduces the
commands for:
z
Configuring a Smart Link Device
z
Configuring an Associated Device
LLDP
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 introduces the commands for:
z
Performing Basic LLDP Configuration
z
Configuring the Encapsulation Format for LLDPDUs
z
Configuring the Encapsulation Format of the Management Address
z
Configuring CDP Compatibility
z
Configuring LLDP Trapping
VLAN
Using the VLAN technology, you can partition a LAN into multiple logical
LANs. This document introduces the commands for:
z
Configuration of Super VLAN
z
Configuration of Isolate-User-VLAN
z
Configuration of Voice VLAN
GVRP
GVRP is a GARP application. This document introduces the commands
for:
z
GVRP configuration
z
GARP Timers configuration
QinQ
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
introduces the commands for:
z
Configuring basic QinQ
z
Configuring Selective QinQ
z
Configuring the TPID Value in VLAN Tags
z
Configuring an Inner-Outer VLAN 802.1p Priority Mapping
BPDU Tunneling
BPDU tunneling enables transparently transmission of customer network
BPDU frames over the service provider network. This document
introduces the commands for:
z
Configuring BPDU Transparent Transmission
z
Configuring Destination Multicast MAC Address for BPDU Tunnel
Frames
