LAG is Blocked on ICX 7250

[vchumakov]

Hello!

My switches : ICX 7250-48p in STACK Core

and a switch ICX 7250-48p with SPR firmware on the floor.

Yesterday upgraded the firmware to SPR0808080f from SPR08070b

And after rebooting, the floor switch lost connection to the network.

I inspected the ports on the core and found that the LAG is not reflecting between the core and the child switch.

Found that as well as state ports are in blocking.

Small output from the kernel.

Port 1/2/4:adm_3_link1 Realtime Information
Status: Up MAC Address: 60-9c-9f-98-13-3c
Actual Speed/Mode: 1G-full Monitor: None
Mirror: None Lock Adddress: Disable
QOS: 0 Flow Control: Enabled
Tag: Enabled Gig Port Default: Neg-Full-Auto
Trunk: 2 State: Blocked

When connecting to the switch via serial port, I found out that it is loaded with SPS firmware, I rebooted it with SPR firmware but it didn't help the situation.
