HA firewall and Stack Switch

[MrBeginner]

I did HA deployment(Active /Passive).I aslo run two L2 cisco switches connected with stack cable. One uplink cable connect from actvie switch to active firewall and one cable are connected from standby switch to standby firewall.

So i would like to know those both uplink interface of both switch should run portfast ( stp disable) ? Should i turn on stp on both ports ?

The FW is l3 so it stop any broadcast, 

You can config portfast to both FW.

Only exception is when you run transparent mode of FW, here you must care of STP.

if that is for HA link, you can run that as Access port - what config you applied on switch port.

@balaji.bandi 

I applied switch port mode access and portfast on switch port. 

it will not be impact HA mode of firewall and traffic flow ,correct ?
