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
describes:
Introduction to BPDU Tunneling
Configuring BPDU Transparent Transmission
Configuring Destination Multicast MAC Address for BPDU Tunnel
Frames
Ethernet OAM is a tool monitoring Layer-2 link status. It helps network
administrators manage their networks effectively. This document
describes:
Ethernet OAM overview
Configuring Basic Ethernet OAM Functions
Configuring Link Monitoring
Enabling OAM Loopback Testing
Connectivity fault detection is an end-to-end, per-VLAN link-layer OAM
mechanism for link connectivity detection, fault verification, and fault
location. This document describes:
Connectivity Fault Detection Overview
Basic Configuration Tasks
Configuring CC on MEPs
Configuring LB on MEPs
Configuring LT on MEPs
RRPP is a link layer protocol designed for Ethernet rings. RRPP can
prevent broadcast storms caused by data loops when an Ethernet ring is
healthy, and rapidly restore the communication paths between the nodes
after a link is disconnected on the ring. This document describes:
