Device Telemetry |
Important: Cisco is constantly striving to advance our products and services. Knowing how you use our products is key to accomplishing this goal. To that end, Cisco will collect device and licensing systems information through Cisco Smart Software Manager (CSSM) for product and customer experience improvement, analytics, and adoption. Cisco processes your data in accordance with the Cisco End User License Agreement, the Cisco Privacy Statement and any other applicable agreement with Cisco. To modify your organization’s preferences for device and licensing systems information, use the pae command. See Network Management Commands → pae.
Introduces the support for device telemetry. This feature allows for the collection of non-personal usage device systems information for Cisco products, which helps in continuous product improvements. This feature is enabled by default. Use the no form of the pae command to disable this feature.
The following commands are introduced as part of this feature:
|

Behavior Change |
Description |
---|---|
Deprecation of snmp-server enable traps license global configuration command |
The command was deprecated. The associated MIB, CISCO-LICENSE-MGMT-MIB, is also no longer supported. In place of the deprecated command and unsupported MIB, use CISCO-SMART-LIC-MIB. |
New flag for the IPv6 SGACL monitor mode |
A new flag has been introduced for the IPv6 SGACL monitor mode. This was introduced to address hardware limitation of a single counter shared for IPv4 and IPv6 traffic. The HW_Monitor counter gets incremented irrespective of the type of traffic, which in turn updates the monitor mode flag. With a separate flag for IPv6 and IPv4 SGACL monitor mode, only the corresponding protocol flag is updated depending on the type of traffic. |
show power and show power detail command output |
The show power and show power detail command outputs are modified to display the correct power information of the standby switch. |
