I have two Cisco 2950 switches connected with a Dell 7810 machine to provide network redundancy.
The machine is equipped with one built in (On Mother Board) Ethernet port and with a dual port NIC “Intel X520-T2 Dual Port 10GbE”. Here I have been facing problem in communicating the dual port NIC with the switch. The built in port is working fine in all cases.
From the adapter settings/properties when the “Speed” of NIC is selected to “Auto Negotiate” it didn’t communicate with the switch. For that switch port is additionally configured and adjust the switch port Speed to “Auto”, after both adjustments a healthy communication is established.
Here can anyone be kind enough to let me know that why the communication didn’t established when only configured from adapter (NIC) settings/properties (Why the switch port configuration need is felt when the adapter is been configured to “Auto”)?
One more thing, as per my understanding the CISCO has now stopped the support for 2950. So if the access to the switch port configuration is not available through Internet Explorer, what should be the alternate to resolve the problem (keeping in mind the switches and machine are in always running mode)?
