Syntax Description

slotid Specifies slot number for the node in a stack. The value can be from 1 to 8.

Default

N/A.

Usage Guidelines

Viewing statistics on a regular basis allows you to see how well your network is performing. When you keep simple daily records, you see trends emerging and notice problems arising before they cause major network faults. This way, statistics can help you get the best out of your network.

This information may be useful for your technical support representative if you experience a problem.

Depending on the software version running on your switch or your switch model, additional or different memory information might be displayed.

You can also use the show memory process name {slotslotid} command to view the system memory and the memory used by the individual processes.

SummitStack Only

When you issue the command with out any parameters:
  • From the stack manager or backup node, the stack displays the current system memory information for the master node and the back-up node in the Active Topology.
  • From a standby node, the stack displays the current system memory information for the master node and the standby node in the Active Topology.

Reading the Output

The show memory command displays the following information in a tabular format:
  • System memory information (both total and free).
  • Current memory used by the individual processes.

The current memory statistics for the individual process also includes the name of the process.

In general, the free memory count for a switch decreases when one or more running processes experiences an increase in memory usage.

If you observe a continuous decrease in the free memory over an extended period of time, and you have not altered your switch configuration, please contact Extreme Networks Technical Support.

Example

The following command displays current system memory information for a switch:
