As in the case with the Layer 2 design, every switch in the network has redundant paths upstream and downstream except each individual
Apr 03, 2026
By access layer redundancy I mean devices that connect to multiple access layer switches for redundancy purposes. For example, a server connecting to two access layer switches,
Oct 21, 2025
What I''d like to know is: if I buy two Layer 3 switches such as the SG550X, what is the best way to configure redundancy to the servers they''re connected to? The best option I found was

Each peer switch processes half of the data volume from the access layer (active/active technology). In contrast to stacking, they remain independent instances and it is only the connected ports that
Aug 01, 2025
The loop-free U topology design provides a Layer 2 access solution with active uplinks and redundancy via an inter-switch link between the access layer switches.

Daisy Chaining Access Layer Switches (2) Here the core switch sees both distribution switches advertise the VLAN 2 subnet, doing equal cost load balancing for traffic destined to VLAN 2 between
Feb 20, 2026
To address this requirement, the MCLAG is extended down to the access layer by using a pair of high-end switches to create redundant uplinks to the aggregation layer. Enough bandwidth is left to the

We provide the reasons for implementing a redundant network, the benefits, the side effects, and the solution for avoiding Layer 2 loops.
Jun 16, 2026
In our server rooms I have a stacked switch pair acting as a distribution switch for every other access switch in the room. I configured LAGs on both ends so LAG uplink ports 1 & 2 on an
