Re: N1108 Series -- "Uplink" ports do not forward

I have defaulted two switches to original. 

Assigned them an IP address only, and set up two extra vlans that are not tagged .

Default setup is Access on all ports 1-12  with vlan 1

Here is the basic config in two switches : 57 and 58

>>

console#show run

!Current Configuration:
!System Description "Dell EMC Networking N1108P-ON, 6.4.1.4, Linux 3.6.5"
!System Software Version 6.4.1.4
!
configure
vlan 2-3
exit
vlan 2
name "Vlan2"
exit
vlan 3
name "Vlan3"
exit
slot 1/0 2 ! Dell EMC Networking N1108P-ON
stack
member 1 2 ! N1108P-ON
exit
interface vlan 1
ip address 192.168.99.58 255.255.255.0
exit
username "admin" password dce0dd972055a72af7c14fd7310c5a98 privilege 15 encrypted
application install SupportAssist auto-restart start-on-boot

exit

I have a PC plugged into 57/1

If i plug a link cable from 57/8 (client) to 58/8 (client) i am able to ping 57 and 58 thru the network

If i move that link cable to 57/9 (uplink) to 58/9 (uplink) i am able to ping 57, but not 58 

It would appear that the uplink ports are not forwarding VLAN1 traffic, even though all ports are set the same.

Below is the SHOW INTERFACES and the SHOW SPANNING-TREE DETAIL  (reduced due to size limits)

This is most annoying, as this fault makes absolutely no sense, and i have to deploy these switches asap.
