This article describes how you can assign an ip address on a cisco. I know you looked into it, but sometimes we miss something that others can see. First off, let me see if i have this straight:
We can now ping sw1 from host a: I am trying to put an ip address on my 2950 switch and what i understand is that you just put an ip address on your vlan and. Sometimes they don’t respond/operate if there is nothing in the vlan (other than the vlan interface).
To verify the ip address set on a switch, we can use the show int vlan 1 command: This means that you can buy a cisco switch, plug in the right cables to connect various devices to the switch,. Then you should be able to remove the address off vlan 1. By default, cisco switches forward ethernet frames without any configuration.
Is there a specific reason why a vlan interface needs to be assigned to a port to be in an up state, like a security reason? Is vlan 20 assigned to any physical interfaces? Or a reason related to how the software/hardware is created? As suggested by previous poster you need to configure vlan 211 and apply an ip address to that interface.
