I'm new to cisco equipment. I have GNS3 emulating an L3 switch whose image is "i86bi-linux-l3-adventerprisek9-15.5.2T.bin". I want to create a cable network with 802.1x and vlan authentication. For this I have been following a video. It starts after configuring the Radius server to type the command "conf t" and then "vlan 10" but when I type the command "vlan 10" it returns "% Invalid input detected at '^' marker." The "^" is below number 1. I wonder why I can't create the vlans if my image is from an L3.
