Hi Ali,

Let me take an example and you can use in your setup

If your access switch as interface vlan 1 with an ip address 1.1.1.1 255.255.255.0 then you must be having one SVI for this vlan 1 on your core switch also like 1.1.1.2 255.255.255.0 so in this scenario your default gateway on access switch should be 1.1.1.2.

NOW I will make the ip default-gateway on the access switch belong to vlan 100 as the following:

core

int vlan 100

ip address 100.x.x.2/24

access switch:

ip default-gateway 100.100.100.2

2)default-gateway for users in vlan 100

D/G: 100.100.100.2

Hi,

1,2,3 is okay. Are you using stp?

You can use any of your gig for etherchannel. People choose them for their own sanity (standard), documentation, simplicity, availability, neat cabling :).

Your sup WS-X4515 has two gig each, The sup in slot 1 is primary while the sup in slot 2 is secondary. For etherchannel you only have a total of 2 gig both first port in sup.

Hi Ali,

Port channels using ports on different modules in same chassis is supported but instaed of using ports from all 4 modules you can use 3/1,3/2,4/1 and 4/2 again it is just a recommendation but you can design the way you want. Also run a command "sh port capability" and confirm if the ports on line card support etherchannel, it should but still you can confirm.

Because you have sup 4 in your chassis all 4 ports on supervisor cannot be active at a same time. Only gig1/1 and 2/1 will be active and once they go down 1/2 and 2/2 will become active.
