This is not a cisco question but a switching question. Unfortunately I have a netgear switch. I bought a Cisco ASA but went cheaper on the switch we only have one in the network.
Internet ---- ASA ---- Switch (Netgear FS50T2 Smart Switch) ---- PCs and Single SBS Server
My switch was working great for about 6 months. Off of this switch I had a single Dynex 8 port switch in the conference room. All was well. Last week, it suddenly started dropping signal on ports. I believe this is about the time that I introduced a second Dynex switch in the network off another drop. THis was to allow a second PC to be put into the warehouse while we switched shipping software.
It worked for two days with no trouble before the port drops occurred. Suddenly, random PCs could not get anywhere in the network. They get the DHCP from the server. It is a single server environment. It cannot ping the server though.
All ports are in the same default VLAN. Nothing changed from when it worked to when it did not. It is a complete star topology. No errors show up in the switch.
I pull the cable from the switch and plug it into another port that is working. Now the PC works! So I am totally frustrated and it appears that the switch is failing on random ports. These failing ports grow over a couple days until I have about 10 not working.
I call netgear and they send me another switch. I hooked this new switch up last night. Everything is working! I walk around and test a bunch of ports. All is well!
This morning I check on everyone and everyone is working!
About 10:30 this morning one office stopped working again. Same issue. At 11:00 or so, another stopped and a few minutes ago, my warehouse PCs stopped working. I moved the cable from the port that warehouse PCs are plugged into and snapped it into an open port on the switch. It works!
Can someone please help me shed some light on why this is not working!? I am at my wits end and I don't think I can talk the folks into spending 1700 on a cisco catalyst just yet with my budget.
Thanks so much!
