CATx are physical cable wiring standards, specifying physical wiring characteristics of the cable, like impedance, number of conductors, twist rate, etc. Switches do not care about the physical properties of the cable. All they care about is whether or not the cable is able to successfully transmit data. It is assumed that cabling used will be within spec ...

Your switch is old. Replace the switch. The device went End-of-Sale in 2004. That's 11 years ago. There's no reason to be running a critical device that old without support. Plus, it's 10/100 Megabit. You could look at the front panel and see if there are any error lights. Switches like that can have fan failures. But it's not worth repairing. A decent ...

So many things: Switches don't give computers internet access. Switches provide physical connectivity to the physical network. Routers give computers internet access. Your computers all need to have a valid ip address configuration. If the switch has internet access then most of the work is already done. All you need to do is to give the computers a ...

On page 9-10 of the manual it states that: This implies that the mac address limit will be reached, and will be remembered until flushed out manually. A port in Static learn mode (learn-mode static) retains a learned MAC address even if you later reboot the switch or disableport security for that port: From documentation: You can authorize specific ...

LACP is the most popular way to do this nowadays since it allows for total bandwidth aggregation and link redundancy. However you rightly point out that you cannot do this with two separate switches, unless they can be stacked together to form a single logical switch. A lot of intel NIC's provide several options in the driver / management application for ...

After many hours fighting this... I believe I have an answer to my own question: In order to set up VLAN's on this switch, I had to set up two things: VLAN Membership (saying which ports belong on which VLAN, as tagged or untagged) PVID Configuration (saying which Port-VLAN-Id is assigned in each port) So, I set both to mimic each other, and traffic is ...

As long as your bond's IP (192.168.49.11) is reachable VIA either switch, you're fine in mode 1. If you have console access to the server, this is easy enough to test - just bring each of the slave interfaces down one at a time and verify you still have connectivity to the outside world (or wherever you need to reach). However, I wouldn't recommend doing ...

Since you are not being provided DHCP through the wall LAN port you'll have to do one of the following: Connect a switch to the wall LAN port and configure a static IP, gateway, netmask, and DNS servers on each computer. Each computer will require its own static IP. Connect a router to the wall LAN port and use it to provide NAT for the computers. I'm ...

So Im assuming your WiFi clients are being served and allowed to be served by the servers. If there is a public address hitting a server that it shouldnt, I suggest there is a port forward or a NAT rule on your router that points any traffic on an outside port of your router to the IP and port of that server. If the public IP always hits the same internal ...

Could it be that the switch is set up to use Spanning Tree Protocol (STP)? 3com has a broken implementation on some older models that will stop forwarding packets for two minutes whenever a link goes up. That bug is fixed in more recent firmware, but might explain why it happens often in the morning (when people turn on their computers), and seldom in the ...
