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