Configure Port Redundant on Summit Stacked Switches

[Ken_Johnathan]

Hi Experts,

Can we configure Port Redundant on Summit Stacked Switches, like below:

Where the Primary Port and Redundant Port are located on 2 Members (A and B respectively) of a SummitStack Switches. Thx.

br,

Hi,

The following article will help you to validate redundant port

Hey Ken. Where are these ports going? If they are going to a redundant core than MLAG will work nicely allowing these ports to be in a LAG. Just throwing it out there. P

yes this must be possible.
Its not docucmented in concepts guide in limitations.
Guidelines for Software-Controlled Redundant Ports and Port GroupsSoftware-controlled redundant ports and port groups have the following guidelines and 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.)
• 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.
• 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
