+There has been a bug with V1.7 which led to complete PCIe Links loss after setting VLAN parameter, e.g. by loading the nat_mch_running_cfg.txt file.
+To update the AVR for the Hub Module use:
+Update via Web access: {{ :projects:cupid:mch_pcie_webupdate.tar |V1.8}}
+Use the MCH web access, there Update MCH. Upload the tar ball.
+Update via script:
+The hex file for V1.8 is offered at fsl00c tftp server under /lobi/firmware/mch_pcie_x80_avr_pcb1_2_v1_8.hex
+An example script also can be found in the same folder via asl740:/common/tftp/lobi/firmware which needs to be edited before usage.
+The script requires telnet access without pw to the MCH.
+Update manually via CLI on MCH:
