How can I config Port-channel from ASA to Core Switch and assign IP?

NetworkRookie

Level 1

I've got 2 ASA and 2 Core Switch stacked. How can I config Port-channel from ASA to Core Switch and assign IP to Port-Channel of ASA, Coreswitch. Look like gateway will be .1 in core and .2 in ASA. 
From ASA1, I already used 4 ports from g1/1 - g1/4 for port-channel and g1/1-2 from ASA2 
here my config: 
Core: 

Vlan 101 

vlan 102

int range g1/0/45-48 

channel-group 1 mode on 

int po1 

sw trunk encaps dot1q 

sw trunk native vlan 101 

sw mode trunk 

int range g1/0/43-44 

channel-group 2 mode on 

int po2 

sw trunk encaps dot1q 

sw trunk native vlan 102 

sw mode trunk 

 

ASA1: 

int g1/1

no sh 

channel-group 1 mode on 

int g1/2 

no sh 

channel-group 1 mode on 

int g1/3 

no sh 

channel-group 1 mode on 

int g1/4 

no sh 

channel-group 1 mode on 

int po1.101 

vlan 101 

ip add 10.1.0.2 255.255.255.248 

no sh 

nameif Inside 

security-level 100 

 

ASA2: 

int g1/1

no sh 

channel-group 2 mode on 

int g1/2 

no sh 

channel-group 2 mode on 

int po2.102 

vlan 102 

ip add 10.2.0.2 255.255.255.248 

security-level 50 

nameif Internal 

 

and here are subnets for 2 vlan: vlan 101: 10.1.0.0/29 vlan 102: 10.2.0.0/29

          You can't assign an IP address  to a layer2 interface , only to Vlan(SVI)

As you said. I can assign IP to int vlan 101 and vlan 102 in CoreSW, so how can I switch int po1 and int po2 access to vlan 101 and 102? 
I've read about Cisco ASA 5506 and higher removed vlan, so I can Switch port access to vlan in ASA5506

as per your question, you need to do as below on the Core switch :

 

 interface Vlan 101 

ip add 10.1.0.1 255.255.255.248 

no shutdown

interface vlan 102

ip add 10.2.0.1 255.255.255.248 

no shutdown

is this cluster deployment, then you need cluster link also.

it's stand alone deployment, not clustering or something like that. 
It's a simple network topo ASA1 > Core > ASA2. Stand alone. 

That above suggested config should work for you.

I've tried your suggest config but it's not work. maybe I did something wrong.
