I want to create ipip tunnel between h3c switch S5800 and cisco

on h3c configuration:

interface Tunel 0
ip address  10.10.250.1 24
source  x.x.x.z
destination x.x.x.y
tunnel-protocol ipv4-ipv4

 on cisco configuration:

interface Tunnel0
 ip address 10.10.250.2 255.255.255.0
 tunnel source x.x.x.y
 tunnel destination x.x.x.z
 tunnel mode ipip 

Tunnel0 current state: DOWN
Line protocol current state: DOWN
Description: Tunnel0 Interface

what is wrong ?

On H3C you need an service-loopback-interface:

[...]

service-loopback group 1 type tunnel

interface GigabitEthernet 1/0/3
   undo stp enable
   port service-loopback group 1
   quit

interface tunnel 1
   ip address 10.1.2.1 255.255.255.0
   tunnel-protocol ipv4-ipv4
   source vlan-interface 101
   destination 2.2.2.2
   service-loopback-group 1
   quit

[...]

I think on cisco it's the same

unfortunately my uplink interface is a trunk, and I cannot set it to "port service loopback group ":

Ten-GigabitEthernet1/0/28] port service-loopback group 1
 Only Access port can be configured as a Service Group.1

I think on h3c s5800 tunnel is not created

dis tunnel-info statistics

Tunnel Allocation Method :    GLOBAL
Avail Tunnel ID Value :       102400

Total Tunnel ID Allocated :   0
LSP :                         0
GRE :                         0
CRLSP :                       0
LOCAL IFNET :                 0
MPLS LOCAL IFNET :            0

Don't use the uplink, use a free port and don't connect a cable to it. This port is used to loopback the traffic between the ASICs. It will come UP without any connected cable ... believe it. :-)
