[c-nsp] ME3600X - Hairpinning/Local Connect

[Ivan]

Hi,

I have seen in the config guides at way of send traffic in and out the
same port or even different ports

http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/15-3_1_S/configuration/guide/3800x3600xscg/swevc.html#wp1051612

I was looking to use the connect statement which seems to be there but
maybe not supported??  Here is what I was trying

interface GigabitEthernet0/5
description Local Connect Test
switchport trunk allowed vlan none
switchport mode trunk
mtu 9216
load-interval 30
no cdp enable
spanning-tree portfast
spanning-tree bpdufilter enable
spanning-tree bpduguard enable
service instance 123 ethernet
 encapsulation dot1q 123
 no rewrite ingress tag pop 1 symmetric
 no shut

interface GigabitEthernet0/6
description Local Connect Test
switchport trunk allowed vlan none
switchport mode trunk
mtu 9216
load-interval 30
no cdp enable
spanning-tree portfast
spanning-tree bpdufilter enable
spanning-tree bpduguard enable
service instance 123 ethernet
 encapsulation dot1q 123
 no rewrite ingress tag pop 1 symmetric
 no shut

ME1(config)#connect test gigabitEthernet 0/5 123 gigabitEthernet 0/6  123
%CONN: invalid segment 1
%CONN: Invalid Command
ME1(config)#

IOS is me360x-universalk9-mz.153-1.S1.bin.  Have I done something wrong or
is this not supported?

Thanks

Ivan
