One of our customer faces with xconenct problem after upgrading ISR 1111 to 16.10.2 or 16.11.01a: I have an ISR1111-4P EoMPLS/xconnect setup running with IOS 16.09.02 and it works find. But when I upgrade to 16.10.02 or 16.11.01a, with the exact same configuration, the xconnect stays down. It's reproducible, I can jump between the versions, it's always the same: with 16.09 it's working, with 16.10 and 16.11 not. * Config here is simple: l2vpn xconnect context L2SERVICE member pseudowire100 member GigabitEthernet0/0/1 service-instance 100 interface pseudowire100 encapsulation mpls neighbor 217.14.74.127 100 control-word exclude interface GigabitEthernet0/0/1 no ip address negotiation auto service instance 100 ethernet encapsulation default l2protocol forward cdp stp vtp dtp pagp dot1x lldp lacp udld esmc elmi ptppd R4 R5 R6 R8 R9 RA RB RC RD RF * After upgrade to 16.10.2 we have next picture: With IOS 16.10.02 I see this ERROR messages: During the boot: *Aug 5 15:42:09.840: %AC-3-AC_SANITY:' title='http://www.cisco.com/cgi-bin/Support/Errordecoder/index.cgi?action=search&counter=0&paging=5&links=reference&index=all&query=%AC-3-AC_SANITY:>' target='_blank'>http://www.cisco.com/cgi-bin/Support/Errordecoder/index.cgi?action=search&counter=0&paging=5&links=reference&index=all&query=%AC-3-AC_SANITY:>;
