Move the cable to a known good port to troubleshoot a suspect port or module. The show module command can indicate faulty, which can indicate a hardware problem. How to solve the problem of port overloading with multiple devices? When a port on a network switch becomes overloaded due to multiple devices drawing too much bandwidth or power, it can lead to network instability, poor performance, or even device failures. One solution would be to create Multiple Spanning Tree (MST) instances, which basically means grouping VLANs together and thereby decreasing the number of spanning tree instances. Core port rate-limiting causing issues on 'tenanted' switching infrastructure We have a 5400zl (J8697a) chassis with 2 J8702a 24 port 10/100/1000 PoE modules installed acting as a core switch in a large 8 switch deployment. A server node uses NIC teaming to create a 4 Gbps channel link from four 1 Gbps ports to a workgroup switch, while the workgroup switch bonds its uplink transceivers to create a 20 Gbps channel to a router. Port channel 1 vlans are 10, 20, 30, 40, 50,101 Port channel 2 vlans are 10, 20, 30, 40, 50, 102 The above port channels are on HP switches. On the Extreme core switch side, I can see the uplink from the HP switches to 2x Extreme.
