## Symptoms

- When accessing the Top Interfaces view in SmartView Monitor, a pop-up message is presented: "An Invalid Argument was encountered".

## Cause

The 'Top Interfaces' view is part of Real Time Monitoring.

By default, the code for Real Time Monitoring supports up to 64 interfaces (including VLANs).

In case the customer has more than 64 interfaces (including VLANs), and the Top Interfaces view is trying to present an interface whose index is higher than 64, we receive an Invalid Argument.
