The S7900E series switches are typically equipped with two SRPUs to
provide active-standby backup. This document describes:
Dual-SRPU system overview
Ignoring Version Check of the SMB
Restarting the SMB
Manually Configuring Switchover Between the AMB and SMB
Virtual Router Redundancy Protocol (VRRP) combines a group of
switches (including a master and multiple backups) on a LAN into a virtual
router called VRRP group. VRRP streamlines host configuration while
providing high reliability. This document describes:
VRRP overview
IPv4-Based VRRP configuration
IPv6-Based VRRP configuration
Smart Link is a solution for active-standby link redundancy backup and
rapid transition in dual-uplink networking. This document describes:
Smart Link Overview
Configuring a Smart Link Device
Configuring an Associated Device
Monitor link is a port collaboration function used to enable a device to be
aware of the up/down state change of the ports on an indirectly connected
link. This document describes:
Monitor Link Overview
Configuring Monitor Link
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:
RRPP overview
Creating an RRPP Domain
Configuring Control VLANs
Configuring Protected VLANs
Configuring RRPP Rings
Activating an RRPP Domain
Configuring RRPP Timers
Configuring RRPP Fast Detection
Configuring an RRPP Ring Group
In the use of fibers, link errors, namely unidirectional links, are likely to
occur. DLDP is designed to detect such errors. This document describes:
Introduction to DLDP
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
