Switches with large MAC address table?

view story

http://serverfault.com – Does anyone know which switches have a large MAC address table ? I see most switches having only 8K, but we need to store way, way more than that (hundreds of K). I know this may seem odd, but trust me, there's no other way we can make our setup work. The only thing we seem to be able to do is install Juniper routers that store up to 1M addresses, but that will get quite costly and we'd rather avoid doing that. ()

Stories similar to Switches with large MAC address table?

I'm learning the network basics at my university this semester. I had a question on the mid-term exam and unfortunately ,I answered it wrong. I have a final exam about an hour from now, and I still don't know what the correct answer of that question is. However, here is my question:

A network of several PCs, switches, and one router. PC 1 has a MAC address X.

How can I see the MAC address table of a Windows network bridge? Is it possible trough command line to find this information?

EDIT: I am interested to see the same table that it is possible to see in the managed switches (e.g. like the Cisco's show mac-address-table or Linux brctl showmacs br0)

I have 6 Juniper switches (EX - 2200) connected to each other as shown in the network topology below. I have two PC's that I am using

PC1 - (used for configuring the 6 switches via minicom) PC2 - to monitor the traffic between the switches via the Ports that are marked with arrows in the diagram.

STEP 1:

I create a new vlan On Switch 3 (SW3) that includes Port 12 and Port 22. I also assign l3-

Configuring Cisco switches is much easier to routers. Layer 3 switches are designed to route packets between different LAN segments similarly to dedicated routers. However, Layer 3 switches do not completely replace the need for routers on a network. How to configure a Cisco layer 3 switch?...

We are planning to purchase new switches for our network. We have three buildings in the same area that are all connected by fiber. Our main building is very large and needs to be connected by fiber from north to south.

Juniper this week unveiled a version of its fabric switches for mid-sized data centers and also increased the scalability of its core Ethernet switches.

Can someone help me with the answer? Thanks in advance
