Hi People,
I'd just like to say right at the beginning,.. I'm a complete n00b at this so please forgive me if these are really easy, stupid questions!!
Currently I have a 4510-48g HP\3COM switch as a core switch for my 4 VLAN network (which I hope to send back cause it doesnt do what I wanted it to do... PBR, which is what I need to route specific VLAN's to specific interfaces on the sonicwall,.. cause sonicwall dont understand trunk or spanning tree,. meh!) This may not happen so I've dug out an old CISCO 1800 sdsl router that has 1 FE0 port and 8 other ports, FE 1-8
The first thing I need to do is get everything to talk to each other. So I plugged the switch into it via its configured trunk port, and configured 4 sub interfaces on the router 1800 and all seemed happy as larry and working.
The problem I have is I dont seem to be able to create sub interfaces on the other ports!?
EXAMPLE:
User Access Verification
Password:
Router>en
Password:
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int fa0.100
Router(config-subif)#exit
Router(config)#itn fa1.100

% Invalid input detected at '^' marker.
Router(config)#
Why is this? I'm struggling to understand why you cant create 4 VLAN's and assign the VLAN the ip instead of the sub interface and then assign the port as a trunk
I dont know if I'm making any sense,.. but bassically,.. on the HP, you create 4 vlans,.. go into each vlan interface and assign the ip you need. then either assign the relevent port interface to access or trunk. if its a trunk, tell it which vlans you want to give access to and you away,... doesnt seem as simple on the cisco,.. can my device do this?
Many thanks in advance,.. Network drawing attached
