Chapter 7 Configure Switch Features
Cryptographic IOS With IOS version 15.2(5)EA.fc4 and later, the default firmware that ships
from manufacturing is the cryptographic IOS. The cryptographic IOS
provides increased network security by encrypting administrator traffic during
SNMP sessions. The cryptographic IOS supports all features of the standard
IOS and these protocols:
• Secure Shell (SSH) Protocol v2
• SNMPv3
• HTTPS
With the cryptographic IOS, HTTPS is the default protocol for accessing
Device Manager. For instructions on accessing Device Manager via secure
connection, see
Access Device Manager on page 48 .
Non-cryptographic IOS software is available to download from the
Product Compatibility and Download Center on
http://www.ab.com .
If you upgrade an existing configuration from IOS 15.2(4)EA3 or earlier to
IOS 15.2(5)EA.fc4 or later, the default switch settings are as follows:
• If you upgrade the switch to the cryptographic IOS, Telnet remains
enabled, SSH remains disabled, but HTTPS becomes the default
protocol for Device Manager.
• If you upgrade the switch to the non-cryptographic IOS, Telnet remains
enabled, SSH remains disabled, and HTTP remains the default
protocol for Device Manager.
Device-level Ring (DLR) DLR is available on Stratix 5400 switches and some models of Stratix 5700 and
ArmorStratix 5700 switches. For a list of switches that support DLR, see
page 21 .
This section covers the following topics:
• Overview
• DLR Port Choices
• DLR Considerations
• Redundant Gateways
• DHCP for Ring Devices
• Multiple Rings
• Configure DLR via Device Manager
• Configure DLR via the Logix Designer Application
