Configuring Interfaces

Hello All,

I'm New with switch configurations and would like to get help.

I have the following scenarion for example:

Router with IP 172.16.3.1/30 on int e 0

that switch 1912 model connected to him with e 0/1 ip 172.16.3.2/30.

Another int on the switch ; e 0/2 connected to PC.

I've configured e 0/1 int, but when I'm trying to cinfigure the e 0/2 int, at the sh run I see the configuration of e 0/2 int on the e 0/1 int.

I don't know what should I do,

Need your help.

thanks ahead.

Re: Configuring Interfaces

Boris,

You cann't configure interfaces with IP addresses on a layer 2 switch.You can have only one VLAN with an IP address for management interfaces. This link has information about configuring your switch:

Re: Configuring Interfaces

What you need to do is after having assigned ip address to your router it should have been 172.16.3.1/24. Connect you 1912 switch assign it a managemetn IP of 172.16.3.2/24. This is because when you use /30 you have already exhausted your host addresses. Your LAN should probably have something like /24 subnets so u have more hosts. Your 1912. would not route for you. You can assign your PC's ip address range of 172.16.3.3 - 172.16.3.254 /24 with default gateway of 172.16.3.1. This would solve your problem
