N7K keepalive issue

Dear All,

we have two CISCO nexus 7010, we was originally have one link between two nexus for keepalive, we decided to make it two links for redundancy purpose,

we made L3 port channel with below configuration,

interface Ethernet1/1                                     
  channel-group 100 mode active
  no shutdown

interface Ethernet2/1
  channel-group 100 mode active
  no shutdown

interface port-channel100
  vrf member vrf_ka
  ip address 192.168.1.2/24

vpc domain 10
  peer-keepalive destination 192.168.1.1 source 192.168.1.2 vrf vrf_ka
  peer-gateway
  reload restore

note: module 1 is Base-T, while module 2 is SFP-based

since that time we recieve below errors, and we can`t recognize the reson of such error

Nexus_BK %VPC-6-PEER_KEEP_ALIVE_RECV_INT_LATEST: In domain 10, VPC peer-keepalive received on interface Po100
Nexus_BK %VPC-2-PEER_KEEP_ALIVE_RECV_FAIL: In domain 10, VPC peer keep-alive receive has failed
Nexus_BK %VPC-6-PEER_KEEP_ALIVE_RECV_INT_LATEST: In domain 10, VPC peer-keepalive received on interface Po100
Nexus_BK %VPC-6-PEER_KEEP_ALIVE_RECV_SUCCESS: In domain 10, vPC peer keep-alive receive is successful
Nexus_BK %VPC-6-PEER_KEEP_ALIVE_RECV_INT_LATEST: In domain 10, VPC peer-keepalive received on interface Po100
Nexus_BK %VPC-2-PEER_KEEP_ALIVE_RECV_FAIL: In domain 10, VPC peer keep-alive receive has failed
Nexus_BK %VPC-6-PEER_KEEP_ALIVE_RECV_INT_LATEST: In domain 10, VPC peer-keepalive received on interface Po100
Nexus_BK %VPC-6-PEER_KEEP_ALIVE_RECV_SUCCESS: In domain 10, vPC peer keep-alive receive is successful

we also notice that HSRP between two nexus flapping right after the above errors

if anyone has any clue for this issue

thanks in advance

/Ali
