Layer 3 routing not possible on this switch. Its a layer 2 switch

ARE you sure .. ?

some one tell me that this switch is layer three

• WS-X4232-RJ-XX—Cisco Catalyst 4000 Layer 3 Services
32-10/100 (RJ-45), plus modular uplink slot


it is showing layer three

Hi Arif,

You are indeed right, it does support Layer3 features. i didn't notice the 4232 card which you mentioned.

So you need to enter the RSM module (4232 card) from the switch by typing session (slot number where this card is installed). Passing the login prompts you will be in the enable mode which would be simply like a router prompt.

There you can assign IP address under each interface VLAN command and can run any simple routing protocol to make things easier.

interface vlanxx

ip address  10.10.1.1 255.255.255.0

interface vlanyy

ip address 10.10.2.1 255.255.255.0

.

.

.

.

configure router rip/eigrp/ospf and make all the above VLANs to be member of it.

Thanks,

Hello Arif,

as explained by colleague you can perform intervlan routing on the L3 module but you probably need to use subinterfaces on port-channel interface that connects to layer2 main switch

I have two devices like this

from the L3 engine you see as CDP neighbor the L2 switch on port-channel subinterfaces

LL3-engineC-1>sh cdp n
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
                  S - Switch, H - Host, I - IGMP, r - Repeater

Device ID        Local Intrfce     Holdtme    Capability  Platform  Port ID
FOX04163236 Switch)
                 Port-channel1.1    161         T S       WS-C4006  3/1
FOX04163236(XX-C-1)
                 Port-channel1.1    161         T S       WS-C4006  3/2
RT-RM-TLD066-WEB-E-1
                 Gig 1              121        R S I      WS-C6506  Gig 3/8
RT-RM-SXR000-WEB-C-1>

the member links are Gig3 and Gig4 in my case ang 3/1 and 3/2 on the switch because it is in slot 3

follow that document to configure the L3 engine.

Hope to help

Giuseppe
