Cost efficiency and ease of setup define network management while potential improvements in complexity handling are noted
Optimizing and configuring for network segmentation is the biggest thing for helping with segmenting traffic management. Configuring QoS on Linksys is pretty easy, especially compared to Cisco QoS, which I am certified in, as it helps ensure that the bandwidth for voice or other applications doesn't bleed over into the data links. In the past, Linksys has been pretty good at network protection, segmenting off that protection for unauthorized access or cyber threats. Cost savings and ease of use are the benefits I've seen from Linksys. It's a little bit less complex to set up and configure compared to Cisco switching. I utilized the VLAN support feature in the Linksys switches. A lot of the networks I have were broken up by VLAN, and I definitely configured them for different VLANs. The best feature of Linksys in my opinion is cost, as they tend to be more cost-effective compared to larger switches or Cisco switches.
