How to Check Real Time Sessions on an Avi SE


The show commands – show serviceengine <foo> flowtable and show serviceengine <foo> tcp-flows is used to check the real-time connections to a pool on an Avi Service Engines. These commands can be used to troubleshoot the issue when a pool or a server is down.

Note: If the traffic coming to the virtual service is high, then these commands may cause the SE crash. The crash issue is fixed in 17.2.8 version. It is not recommended to run these commands on Avi Vantage 17.2.6 and previous versions.


The show serviceengine <foo> flowtable and show serviceengine <foo> tcp-flows commands apply to the entire SE. It is recommended to add the desired filters to these commands to filter the output based on the requirement.

conn_type frontend, backend, or both
core_num Core number
ip_addr Ip address of either src or dst in dotted decimal
ip_mask Ip mask in dotted decimal
listening_ports Listening sockets only
port Src port or Dst Port

> show serviceengine flowtable filter
core_num Core num
dst_ip_addr Destination IP address
dst_ip_mask Destination IP address mask
dst_port Dst port range 1
dst_port_hi Dst port range 2
