ASA Trunking / Port channels

[J001]

Hi,

I have an ASA 5525 and would like to trunk the inside interface to 2 separate core switches on the same vlan (88) for resiliency. The two switches are Cisco 6500 switches that have Vlans using HSRP between them.

I am curently using version 8.6 on the ASA 5525.

How I can trunk the ports to two switches or do I use port-cahnnel ? The ip address will be configured on the core switches rather than on ASA so I just need 2 x trunk ports on same vlan to ASA.

I-----------switch 1 Vlan 88 HSRP .250
ASA5525 I I
I-----------switch 2 Vlan 88 HSRP .250



TIA
