What is Broadcast Address?

[sharapov]

To set up Cisco 5500 swith I need IP address, network mask and broad cast address. I know what are the first two are (ex. IP: 192.33.1.10, Network Mask: 255.255.255.0) But what is the broadcast address? How do I determine which one to use. Can somebody explain?

Thanks.

As you are aware, an IP address consists of a network part and a host part. In you case you are using a Class C address (refer to your netmask) and so your network number part is 192.33.1 and your host part is 10.

The broadcast host address is all bits set to 1 so in your case it is 255. Therefore the full broadcast address is the combination of the network part and the host part - 192.33.1.255
