Basic Layer 2 Setup and Buffer Tuning of the
S25P for Storage Environments
Introduction
This document is intended for the users of S-Series S25P switches running FTOS 7.8.1.0 and configured
for use in a storage environment. This document describes:
•
Using the console port to enable all ports on the switch for Layer 2 switching
•
Verifying that the installed FTOS software is FTOS 7.8.1.0
•
Setting up passwords for managing the switch. For details on management, see the Management
chapter in the FTOS Configuration Guide for the S-Series and the Control and Monitoring chapter in
the FTOS Command Reference for the S-Series.
•
Optimizing the buffer for use in pure storage environments
This document does not cover:
•
Installing optional modules. For installation details, see the document Installing S25P Systems. For a
configuration example, see
•
Adding the switch to an S-Series stack. For stacking configuration details, see the Stacking chapters in
the Configuration Guide and the Command Reference listed above.
•
Layer 3 (IP addressing) configuration. For details, see the Interfaces and IP Addressing chapters in the
Configuration Guide and Interface Commands chapter in the Command Reference listed above.

Page 2: Accessing The Console Port
Accessing the Console Port Step Task Install a straight-through RJ-45 copper cable (a standard Ethernet cable) between your system and the console port of the S-Series switch. The console port is at the far left of the faceplate. Turn on the switch by connecting it to power (there is no on/off button). After the switch boots up (the status messages stop), press Enter twice to get the EXEC mode prompt. -

- Page 5 Managing the Buffer Profile and Setting up Flow Control Buffer profile management, also called buffer tuning or buffer carving, enables you to modify the way your switch allocates buffers from its available memory, and helps prevent packet drops during a temporary burst of traffic.

- Page 7 To apply the configuration, above, to other stack members, use the following commands. The interface range used and port-pipes (“ ”) designated would depend on the S-Series model. The following port-set 0-1 sequence presumes that the subject stack member is an S25P model. For an example of configuring an S50N model, see Basic Layer 2 Setup and Buffer Tuning of the S50N for Storage Environments.
