What model Cisco switch? &nbsp;Do you have spanning tree enabled on it? &nbsp;<br />
<br />
Could be that when the D-Link switch is re-booting, the Cisco switch is going through the learning process which if the switch is not configured correctly will cause all traffic to stop for about 30 seconds.

Hi,<br />
<br />
We have a D-link network stack on our network, along with a Cisco switch. The D-link stack and other D-link switches were introduced a number of weeks ago and all has been working fine, until a few days ago.<br />
<br />
The issue we are experiencing seems to be down to the main D-link stack switches (D-Link DGS-3420-52T) One of the switches in the stack appears to be having issues booting and seems to knock the other switches off the network. &nbsp;There is also a Cisco switch on board (existing one prior to the upgrade) this switch seems to be freezing when the D-link switch is attempting to boot.<br />
<br />
Is anyone able to provide any details on what could possibly cause this?<br />
<br />
Thanks

Network switch issues

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
