If you compare the last couple of versions the main differences actually are: Release highlights In this release, we are excited to support the following features and enhancements. Below are the key highlights: Introducing a new onboarding flow for cloud and hybrid operating modes: two powerful ways to manage your Catalyst 9000 switches from the Meraki dashboard. These modes give you the flexibility to choose between a fully cloud-managed experience (cloud operating mode) or a hybrid approach (previously referred to as cloud monitoring), that offers configuration via an embedded cloud CLI while leveraging the cloud for monitoring and troubleshooting. Learn more http://cs.co/9000F98vQ (Note that the new onboarding process for hybrid and cloud operating modes will be rolled out in phases. If you don’t see the new UI while adding your Catalyst switches to a network, please be assured it will be available soon. We appreciate your patience and understanding as we work to bring this feature to all eligible organizations.) Configuration Templates now supports C9200L switches Intelligent Capture now works with non master devices in stacks of C9300/MS390 Meraki Authentication (Meraki Auth) Alternate Management Interface (AMI) Port Schedules SNMPv3 Encrypted Traffic Analytics Energy Efficient Ethernet MAC Allow Lists Before you upgrade or migrate: key considerations Layer 3 switches with a DHCP management IP address are not supported. Please configure a static IP address for the management interface to avoid network disruptions and improper traffic flow. If the L3 switch’s default route and management interface gateways are NOT the same prior to the upgrade, after the upgrade to IOS XE all switch traffic will use the management interface’s DHCP acquired gateway as a next hop. Layer 3 switches cannot run DHCP servers on uplink interfaces. Please note that interfaces that have been designated as a preferred uplink cannot also run a DHCP server. Interfaces with both Preferred Uplink and DHCP server configurations will have the DHCP server configuration disabled on that interface. Switches using the Alternative Management Interface (AMI) will require an L3 SVI to be configured for the same vlan assigned to AMI. For AMI to work, your network must have AMI configured and your switch must have an SVI configured matching that AMI vlan. New known issues Clients Static DHCP reservation cannot be changed. Workaround requires removing static reservations and recreating them. Configuration application fails due to bad-cli errors related to et-analytics during each config push. Changing destination port configuration for encrypted traffic analytics, while active, can corrupt config. As a workaround, disable then re-enable with new port config. Named VLAN column is not displaying any values in the switches client summary table. IPv6 route for DNS is set with an empty Gateway IP, leading to configuration application failure. Devices lose all configurations after an upgrade from 17.15.2 to 17.15.3. Rebooting or shutting down a switch shortly after upgrade (17.15.2 to 17.15.3) might not preserve “safe-config”. Please wait 30 min after upgrade to ensure configuration is marked ‘safe’. MTR live tool does not function from the dashboard. 9200L 8-member stack: Stack merge occurs due to incompatibility when installing a new image. 8-member stacks may experience longer boot or upgrade times. Issue with upgrading a stack of 8 members on the 9200L series from one cloud-native IOS XE version to another. The Default VLAN profile API appends new configurations instead of overwriting existing ones potentially leading to unexpected behavior. The device uptime displayed for stack standby members is incorrect. Fixed issues Port scheduling is supported on this version. LACP is not functioning on the network module ports of NM-2Y modules. Transitioning from cs to ios xe 17.15: unsupported features The following CS features are not supported in this release: Sticky MAC Client Tracking does not work on 10G-MGig, 25G, 40G and 100G C9K ports Geo-cloud Certain features will be added to the IOS XE versions in future releases.
