Interfaces remain down

[qos]

Switch config on interface has the following:

dev 1

int g1/0/2

port link-mode route

combo enable copper

undo shutdown

ip address

dev 2

int g1/0/2

port link-mode route

combo enable copper

undo shutdown

ip address

dis int brief shows link and protocol down.

simulator config:

#
# Devices PC A
#
device_id = 1
device_model = SIM2100
board = SIM2101 : memory_size 512
host_ip = 10.1.1.1
#
device_id = 2
device_model = SIM2100
board = SIM2101 : memory_size 512
host_ip = 10.1.1.1
#
# Telnet Management Links
#
device 1: interface 1 <--> host : "VirtualBox Host-Only Ethernet Adapter"
device 2: interface 1 <--> host : "VirtualBox Host-Only Ethernet Adapter"
#
# Link Switch to Switch
#
device 1 : interface 2 <--> device 2 : interface 2

Removing host_ip = 10.1.1.1 from the simulator config brought the interfaces up.

Yes, we cannot give IP's to the devices from the simulator script. That is why interfaces were down.
