New and Changed Software Features in Cisco IOS XE 17.16.1a
|
Feature |
Description |
|---|---|
| Configure Source Interface for High Speed Logging |
From Cisco IOS XE 17.16.1a, you can configure source interfaces for High-Speed Logging (HSL) and SysLog for security logging in Cisco SD-WAN Manager. You can also enable HSL for your firewall messages, to allow a firewall to log records with minimum impact to packet processing. |
|
Disablement of Weak SSH Algorithms |
From Cisco IOS XE 17.16.1a, the ssh-rsa algorithm is disabled by default on port 22 to improve security. |
| When Cisco IOS-XE autonomous devices transition to Cisco SD-Routing mode, the Unified Threat Defense (UTD) Container Migration feature ensures that existing container functionalities are preserved. From Cisco IOS XE 17.16.1a you can detect, upgrade, and manage UTD Security Virtual Images through Cisco Catalyst SD-WAN Manager. For devices without pre-existing containers, you can also install and manage UTD images using policy groups. | |
|
From Cisco IOS XE 17.16.1a, Cisco Catalyst SD-WAN Manager enables site-to-site speed tests to measure bandwidth between devices over DMVPN tunnels. These tests check upload speed from the source device to the destination, and measure download speed from destination to the source device. |
|
|
If you have configured crypto VPN solutions such as DMVPN, FlexVPN or Layer 3 VPNs on SD-Routing devices, you can use Cisco Catalyst SD-WAN Manager to visualize the VPN solution deployed in the network and observe the functioning of the devices using various states, stats, charts and events.Having high visibility into the network can help identify errors in real time therefore reducing the network down time. |
|
|
In Cisco IOS XE 17.16.1a, you can now monitor TCP and RTP traffic on DMVPN tunnels for IKEv2 traffic using Application Response Time (ART) monitor and Media monitor respectively. This functionality is only supported on DMVPN tunnels with IKEv2 encryption. |
|
|
From Cisco IOS XE 17.16.1a onwards, you can retrieve events sent to the IOS process in the binary trace using the show logging process IOS module nhrp command, without enabling DMVPN event tracing. |
|
|
From Cisco IOS XE 17.16.1a onwards, you can use HTTP-based authentication for EST Client Support, using the enrollment http username command. |
|
|
From Cisco IOS XE 17.16.1a, the output for the show cellular 0/x/0 connection command includes Access Point Name (APN), and Cellular Link Uptime parameters. |
|
|
From Cisco IOS XE 17.16.1a, asymmetric carrier delay is supported on Cisco Catalyst 8500 Series Edge Platforms. |
|
|
From Cisco IOS XE 17.16.1a, two new keywords detail and history) are introduced for the show power command. The detail keyword provides power usage information for each component, and the history keyword provides the power consumption history for the device. |
|
|
From Cisco IOS XE 17.16.1a, Segment Routing over IPv6 dataplane supports these functionalities:-
