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.

BGP EVPN VXLAN
|
The following BGP EVPN VXLAN features are introduced in this release:
|
device tracking export oper data command |
The device tracking export oper data command is introduced. This command is used to export information like Switch Integrated Security Features (SISF) IP addresses and MAC address tables to the Crimson database.
|
Distributed Processing for IPsec |
Distributed processing increases the IPsec throughput which was earlier limited to 100G. On the Cisco Catalyst 9300X Series Switches, IPsec throughput is increased to 200G.
|
hw-module ecomode serdes-disable command |
The hw-module ecomode serdes-disable command is introduced. Empty SFP ports have ecomode enabled and are powered down by default to save power. Use the hw-module ecomode serdes-disable command to turn off ecomode.
|
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.
|
NAT SSO support with StackWise Virtual |
Introduces support for synchronization of the NAT state information across active and standby devices so that if the active device fails, the standby device can take over smoothly and update its software without interrupting In-Service Software Upgrade (ISSU).
|
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.
|
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.
|
Smart LEDs |
The hw-module switch ecomode command is introduced. Use this command to turn off all port LEDs at once.
|
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.

New on the WebUI |

show crypto engine accelerator statistic command |
The show crypto engine accelerator statistic command is now available on the Cisco Catalyst 9300 Series Switches and Cisco Catalyst 9300X Series Switches. |
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. |
