Solved: Cisco 3560 L2 or L3?

Hieu Cao · ‎10-15-2009

Is there a simple way to really verify that the cisco 3560 is a layer 2 or layer 3 switch? or is it actually dependent upon the ios image that it's running?

Switch model number is WS-C3560-48PS-S

Thanks.

3560 is L2/L3 switch

if you do not enable ip routing the switch will operate as L2

switch

use this command to make it L3

ip routing

to make only L2

no ip routing

good luck

I would try and setup 2 gateways, connect 2 hosts and see if they can ping eachother;

example:

Int vlan 100

ip adress 10.10.10.1 255.255.255.0

no shut

conf t

int gi 0/1

switchport mode access

switchport access vlan 100

no shut

connect host 1 to gi 0/1

repeat for 2nd host

Hi,

i am trying to configure 2 vlan with different network

vlan10 - 192.168.10.1/24

vlan50 - 192.168.50.1/24

port assigned to vlan10 is fa0/1-4 and fa0/5-8 for vlan50

client ips are

192.168.10.11-14 /24 for vlan10 with gateway 192.168.10.1

192.168.50.11-14 /24 for vlan 50 with gateway 192.168.50.1

however they cant reach each other, i am trying Layer3 switching and i am did the ip routing as what you advise but did not work..

please advise if i did wrong.. thanks and advance.!!

Have you try with interface VLAN ?

(Config)#Int VLAn 10

#ip address 192.168.10.1 255.255.255.0

(Config)#Int VLAn 50

#ip address 192.168.50.1 255.255.255.0

Please try this and let me know if its working or not

I have c3560cx-12pd-s and i am not able to reach a host on the second vlan(20). I can ping to vlan 10, vlan 20, but the host in vlan 20 is unreachable for me. Can anybody advice me please? Is it necessary to use two switches or I am able to rout on this switch(c3560cx)?
