I was hoping someone can provide some information on how to set an IP address on the FastEthernet interface. i.e FastEthernet0/0/3. When I try to set the IP address, I get the following error:
"IP addresses may not be configured on L2 links."
So I tried a few options, but all failed:
Option 1: "no switchport" command.
this failed with : no switchport Command rejected: Not a convertable port.
Option 2: make it via a Vlan
This failed as well. Below is my configuration for vlan. I can ping address 10.75.22.1, but I can't ping the adj. router i.e 10.75.22.2. I think this may be an issue with arp? Notice below that Vlan100 is using the mac address of the GE interface??? What am I doing wrong?
switchport trunk native vlan 100
switchport mode trunk
ip address 10.75.22.1 255.255.255.252
vlan-id dot1q 100
