There are 2 ways to allow a Cisco Catalyst 2950 Switch to own an IP address so that it can be pinged by hosts on the network. First, you may try to run the command 'setup' in Priviledged EXEC mode and follow the instructions of the setup program that follows. If I remember correctly, there is a portion in the setup that prompts you to enter an IP address for the switch. You do, however, need to answer 'YES' when prompted to configure the switch for management in order to see the prompt for an IP address I think.
Second, by default, all the FastEthernet ports on the Cisco Catalyst 2950 Switches fall under a Virtual LAN, VLAN1. An IP address may be assigned to this VLAN1. This would basically mean that you are giving an IP address that would define the whole switch, which is what you are trying to do anyway. What you have to do is to get into Priviledged EXEC mode first by using the 'enable' command. Following this, issue the 'config terminal' command to get into Configuration mode. Then, issue an 'interface VLAN1' command to get into the configuration context of VLAN1. From here, you can set the IP address for the switch by issuing the command "ip address x.x.x.x m.m.m.m" (Where x.x.x.x is the IP address you want, m.m.m.m, the subnet mask). Remember to save :)
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
