New Network Essentials features with resolved caveats

Improvements

Day 0 Startup Enables Type-6 Passwords (Master-Key) in Addition to Type-7 Passwords

• The CLI Setup program now allows you to set the password encryption level for enchanced security.

Secure Data Wipe

• Secure data wipe is a Cisco wide initiative to securely erase or wipe sensitive, identifiable information on storage devices on all IOS XE based platforms. Secure data wipe uses NIST SP800-88r1 compliant secure erase commands to erase data when removing products due to RMA, upgrade/replacement, or system end-of-life.

Bug fixes

• CSCwb68465 - IE3x00: MRP IP connectivity issue.

Important Notes

Startup Config is Always Read from Flash

• Beginning in Cisco IOS XE Release 17.10.1, the startup configuration is always read from flash. The latest configuration is available only in flash when you save the running config, irrespective of the booted media (for example, flash, sdflash, or usbflash ) and the boot mode (install or bundle).

SMU Installation: Boot in Install Mode

• Software Maintainance Upgrade (SMU) installation has been supported in both bundle boot and install mode. However, beginning in Cisco IOS XE 17.9.1, the switch must be booted up in install mode to support SMU installation.

• SMU installation stops if the device is booted up in bundle mode. If the device is booted up in install mode, SMU installation continues to work as before.

IE3400: Hardware Changes may Require Action

• Some hardware components on the Cisco Catalyst IE3400 Rugged Series and Cisco Catalyst IE3400 Heavy Duty Series switches have changed. The changes, which are automatically handled by the IOS XE software, do not affect switch functionality or the ordering process. New units shipped after May 31, 2022 have the hardware change.

• However, you may need to upgrade the software, depending on which base switch and expansions module you have, as shown in the following table.
