NETGEAR 8800 User Manual
You configure the software-controlled redundant port feature either to have the redundant link
always physically up but logically blocked or to have the link always physically down. The
default value is to have the link physically down, or Off.
always physically up but logically blocked or to have the link always physically down. The
default value is to have the link physically down, or Off.
By default, Smart Redundancy is always enabled. If you enable Smart Redundancy, the
switch automatically fails over to the redundant port and returns traffic to the primary port
after connectivity is restored on that port. If you do not want the automatic restoration of the
primary link when it becomes active, disable Smart Redundancy.

Guidelines for Software-Controlled Redundant Ports and Port
Groups
Software-controlled redundant ports and port groups have the following limitations:
•
You cannot have any Layer 2 protocols configured on any of the VLANs that are present
on the ports. (You will see an error message if you attempt to configure software
redundant ports on ports with VLANs running Layer 2 protocols.)
redundant ports on ports with VLANs running Layer 2 protocols.)
•
The primary and redundant ports must have identical VLAN membership.
•
The master port is the only port of a load-sharing group that can be configured as either a
primary or redundant port. Also, all ports on the load-sharing group must fail before the
software-controlled redundancy is triggered.
software-controlled redundancy is triggered.
•
You must disable the software redundancy on the master port before enabling or
disabling load sharing.
•
You can configure only one redundant port for each primary port.
•
Recovery may be limited by FDB aging on the neighboring switch for unidirectional traffic.
For bi-directional traffic, the recovery is immediate.
Configuring Software-Controlled Redundant Ports
When provisioning software-controlled redundant ports, configure only one side of the link as
redundant. In

membership.
To configure a software-controlled redundant port, use the following command:
configure ports <primaryPort> redundant <secondaryPort> {link [on | off]}
The first port specified is the primary port. The second port specified is the redundant port.
To unconfigure a software-controlled redundant port, use the following command and enter
the primary port(s):
