There are no new hardware features in this release.
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.

Feature Name |
Description |
---|---|
IP SLA Probe Configuration Modification Capability |
Introduces support to reconfigure the parameters of a scheduled IP SLA session using the configure replace command.
|
mDNS Protocol Options |
The mDNS protocol option is introduced in the device sensor filter spec command. This allows the user to apply the mDNS protocol TLV filter list to the device sensor output. The device sensor filter list mdns command is introduced to create a mDNS protocol filter containing a list of Type-Length-Value (TLV) fields that can be included or excluded in the device sensor output. The tlv command is introduced to configure the list of Type Length Value (TLVs) in mDNS protocol configuration mode.
|
OSPF Local RIB Path Limit Enhancement |
The OSPF Local RIB Path Limit feature is designed to restrict the number of paths stored by OSPF in its Local RIB, offering enhanced control over network path selection. With the maximum-paths command enabled, the network administrators can now control the number of paths OSPF installs in the Local RIB for a specific prefix.
|
Precision Time Protocol |
Precision Time Protocol (PTP) is defined in IEEE 1588 as Precision Clock Synchronization for Networked Measurements and Control Systems, and was developed to synchronize the clocks in packet-based networks that include distributed device clocks of varying precision and stability. This feature is implemented on the Cisco Catalyst 9200CX Compact Series Switches. |
Programmability:
|
The following programmability features are introduced in this release:
|
show reload history command |
The show reload history command is introduced. It displays the reason for device reload and its history.
|
spanning-tree bpdu sender-conflict command |
This feature allows the user to enable spanning tree protocol BPDU sender conflict feature using the spanning-tree bpdu sender-conflict command. When the device is in RSTP mode, BPDU packets are transmitted every two seconds from a designated port to a non-designated port. When you use the spanning-tree bpdu sender-conflict command, if there is any change in the RSTP mode due to sender conflict, the device generates a notification.

Switch Integrated Security Features (SISF) – Enhanced Throttling Limit for ARP Packets |
In Cisco IOS XE Amsterdam 17.3.1, a throttling limit was introduced to mitigate high CPU utilization scenarios. In a five second window, a maximum of 50 ARP broadcast packets per source IP were processed by SISF. In Cisco IOS XE 17.14.1, this limit is increased to a maximum of 100 ARP broadcast packets for each source IP. When the limit is reached, incoming ARP packets are dropped. |
