The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Enabling Third-Party Optics During AutoInstall |
During AutoInstall, the system will detect, third-party optics automatically. Unlike the default boot up process, the third-party optics will not move to err-disabled state during AutoInstall. In the default boot up process, you need to configure the service unsupported-transceiver command to detect the third party optics after system boot. When AutoInstall is successful, the third-party optics are enabled. In all other cases, these optics will be in the err-disabled state. The service unsupported transceiver command is not saved into the startup configuration, and when the configuration is saved using the write memory command, and the system is reloaded, the third-party optics will move into the err-disabled state. This feature is enabled by default. You can use the no service unsupported-transceiver command to disable the third-party optics, after the auto install is complete. |
There are no behavior changes in this release.

|
IP DHCP Server Changes to Limit IP Assignment to Next Hop only |
Allows you to assign DHCP IP address only to the neighbouring device in an interface using the ip dhcp restrict next hop command. When this command is enabled, the DHCP server in the interface uses the MAC addresses in the DHCP packet and compares it with the addresses in the Cisco Discovery Protocol (CDP) or Link Layer Discovery Protocol (LLDP) cache table. If the MAC addresses match, then the DHCP IP address is assigned to that device.
