help setting up second vlan on 3560 swt

[loveroots]

hi i would like to get help setting up a second vlan. I have a network which is in need of additional IP. I wanted to configure sample of how it could be done as below is what i nee to know.current setup for example 3 3560 switch with a default vlan call vlan 1.. Switch1 uplink to 2800 series router on ge0/0 fro swt port fe0/1

vlan1 vlan1 vlan 1
router ==3560 switch1==3560 switch2 =========3560 switch3

Below I want to create second vlan do I need to connect a cable from swt2 to router for vlan2
and also add vlan 2 ip network in my routing protocol and add a dhcp for it. vlan1 vlan2
router(ge0/0)===(fe0/1)3560switch==3560 switch===3560 switch
(ge0/1)===(fe0/24)

have you tried
config t
int vlan 5
ip address x.x.x.x
exit

sh vlan

Myself I would either run the 2nd router connection to the first switch and then just trunk vlan 2 to the other switches then you can put vlan 2 on any switch you want . You could also run both subnets off the existing connection using subinterfaces on the router and setting up a trunk port on switch 1.

Are your 3560s running IP routing or just Layer2?

You don't need a seperate physical link from your router to carry a 2nd VLAN (see: 802.1q trunking)

You shouldn't really daisy-chain your switches one off the other - install them in more of a "star" topology. Perhaps like this, if you only have 2 ethernet interfaces on your router:

Router) ===.1q trunk=== 3560#1 ===.1q trunk=== 3560#3
) ===.1q trunk=== 3560#2

Regardless, to add the new VLAN to the network you need to do this:

- create the new VLAN on all devices that will be using it.
- create the new VLAN's VLAN interface on your Layer3 device that does your routing.
- reconfigure the router-switch and switch-switch links interfaces so they are .1q trunks and add the newVLAN to each one
- configure the edge switch ports to the new VLAN where it's needed.
