Description |
||||
---|---|---|---|---|---|
The Managed Cellular Activation solution provides a programmable subscriber identity module (SIM), called an eSIM, a physical SIM card that you can configure with a cellular service plan of your choice. When ordering a pluggable interface module (PIM) to provide cellular connectivity for your router, choose a PIM model with a preinstalled eSIM. The Managed Cellular Activation solution comes with a “bootstrap” cellular plan to provide internet connectivity with a limited amount of data intended only for Day 0 onboarding of the device to your cellular plan. For information about configuring Cisco SD-WAN Manager with the details of your cellular plan in preparation for onboarding the device, see the Cisco Managed Cellular Activation Configuration Guide. Prepare the configuration in Cisco SD-WAN Manager before powering on and onboarding the device, to avoid running out of the limited data in the bootstrap cellular plan. Added Cisco Managed Cellular Activation (eSIM) support for the following Pluggable Interface Module (PIM) model:

---|---|---|---|
This feature allows you to perform management operations for SD-Routing devices using Cisco Catalyst SD-WAN Manager. You can use a single network manage system (Cisco Catalyst SD-WAN Manager) to monitor all the SD-Routing devices and therefore help in simplifying solution deployments. |
|||
Segment Routing (SR) can currently be applied on Multiprotocol Label Switching (MPLS) dataplane. From Cisco IOS XE 17.12.1a, SR is supported over the IPv6 dataplane for the following protocols:
In addition, the following functionalities are available for Segment Routing over IPv6 dataplane:
|
|||
This feature allows you to delete the entries from the logging buffer. You can configure the local syslog retention period after which the entries are purged from the device automatically. To enable this feature, use the logging purge-log buffer days command. |
|||
This feature helps users to set a minimum frame size of 72 bytes on an EPA interface using the plim min-frame-length 72byte command. |
|||
Cisco Unified Border Element (CUBE) Features | |||
From Cisco IOS XE Dublin 17.12.1a onwards, High Availability in CUBE supports IPv6 flows. |
|||
From Cisco IOS XE Dublin 17.12.1a onwards, VoIP Trace for SIP messages displays cause code in the cover buffer. |
