From “show interface” output, the rx/tx counters of TenGE4/0/0 matches that of tx/rx counters of 4/0/1. So L2XC is working between them. For the other L2XC pair, the rx counter of TenGE7/0/1 matches that of the tx counter of 7/0/0 so that also seem fine. The rx of TenGE7/0/0 and tx of 7/0/1 are all 0’s which also matches. Thus both L2XC pairs appear to function as expected. Are you expecting packets in the TenGE7/0/0 to 7/0/1 direction and so think it is not working there? Then you need to find out why TenGE7/0/0 is not receiving any packets. -John

I want to only do vpp# set interface l2 xconnect x1 x2 vpp# set interface l2 xconnect x2 x1 vpp# set interface l2 xconnect y1 y2 vpp# set interface l2 xconnect y2 y1 so that all traffic from port x1 is sent to port x2 and vice versa , also all traffic from port y1 is sent to port y2 and vice versa. but only one set of them works at the same time , for example only x1 and x2 works but y1 and y2 not working if i change the mode of x1 and x2 interface to L3 mode , y1 and y2 interface will work in L2 mode I test this situation with l2 bridge and i have the same problem. May i know ,why it doesn't work if i set l2 (xconnect or bridge) for multiple interface ??? here is my configuration and commands : for l2 xconnect test : vpp# set int state TenGigabitEthernet4/0/0 up vpp# set int state TenGigabitEthernet4/0/1 up vpp# set int state TenGigabitEthernet7/0/0 up vpp# set int state TenGigabitEthernet7/0/1 up vpp# set interface promiscuous on TenGigabitEthernet4/0/0 vpp# set interface promiscuous on TenGigabitEthernet4/0/1 vpp# set interface promiscuous on TenGigabitEthernet7/0/0 vpp# set interface promiscuous on TenGigabitEthernet7/0/1 vpp# set interface l2 xconnect TenGigabitEthernet4/0/0 TenGigabitEthernet4/0/1 vpp# set interface l2 xconnect TenGigabitEthernet4/0/1 TenGigabitEthernet4/0/0 vpp# set interface l2 xconnect TenGigabitEthernet7/0/1 TenGigabitEthernet7/0/0 vpp# set interface l2 xconnect TenGigabitEthernet7/0/0 TenGigabitEthernet7/0/1 vpp# show interface Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count TenGigabitEthernet21/0/0 5 down 9000/0/0/0 TenGigabitEthernet21/0/1 6 down 9000/0/0/0 TenGigabitEthernet24/0/0 7 down 9000/0/0/0 TenGigabitEthernet24/0/1 8 down 9000/0/0/0 TenGigabitEthernet4/0/0 1 up 9000/0/0/0 rx packets 2803151 rx bytes 700562045 tx packets 3693049 tx bytes 3791177782 tx-error 62 TenGigabitEthernet4/0/1 2 up 9000/0/0/0 rx packets 3693049 rx bytes 3791177782 tx packets 2803151 tx bytes 700562045 TenGigabitEthernet7/0/0 3 up 9000/0/0/0 tx packets 4799610 tx bytes 3764207865 TenGigabitEthernet7/0/1 4 up 9000/0/0/0 rx packets 4799610 rx bytes 3764207865 local0 0 down 0/0/0/0 vpp# show mode l3 local0 l2 xconnect TenGigabitEthernet4/0/0 TenGigabitEthernet4/0/1 l2 xconnect TenGigabitEthernet4/0/1 TenGigabitEthernet4/0/0 l2 xconnect TenGigabitEthernet7/0/0 TenGigabitEthernet7/0/1 l2 xconnect TenGigabitEthernet7/0/1 TenGigabitEthernet7/0/0 l3 TenGigabitEthernet21/0/0 l3 TenGigabitEthernet21/0/1 l3 TenGigabitEthernet24/0/0 l3 TenGigabitEthernet24/0/1 I have checked connectivity and sure that's correct Regards, david
