Troubleshooting SRX reth interface with a cisco trunk port

I have an SRX connected to a cisco switch. The srx is configured with reth interfaces with VLAN-tagging and without lacp enabled. From the cisco side, the port is a normal trunk port.

The ping between SRX and cisco is not coming up, after troubleshooting and researching it doesn't seem to be any weird requirement for cisco switch.

did anybody face this issue and resolved it?

PS: all security zones and policies are properly configured.

SRX:

root@SRX-Active# show interfaces reth0

vlan-tagging;

redundant-ether-options {

redundancy-group 1;

}

unit 10 {

description Servers;

vlan-id 10;

family inet {

address 192.168.1.1/24;

}

}

Cisco Switch:

interface GigabitEthernet1/0/24

description **Link to SRX1 ge-0/0/6**

switchport mode trunk

end
