Author: Luis Fernandes Updated

Summary

high rx and tx for loopback interface

Overview

The loopback interface on the Exinda Appliance can show high traffic.

You can find it under System > Diagnostics > NIC.

For example, the entry below shows that the loopback received and sent 5.7 TebiBytes.

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:14663604525 errors:0 dropped:0 overruns:0 frame:0
          TX packets:14663604525 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:6307971471326 (5.7 TiB)  TX bytes:6307971471326 (5.7 TiB)
 

Cause

The Exinda Appliance uses the loopback for internal communications process accessing services like the web server, the database server and acceleration.

Resolution

The high packets that are seen do not indicate an error, just normal Exinda operation.
