Software Features in Cisco IOS XE Dublin 17.11.1

Feature Name

Description

Default Limits for redistributed routes and LSA in OSPF

Default values have been assigned to the number of redistributed routes and LSAs in OSPF to prevent the device being flooded with routes. The default values for redistributed routes is 10240 routes. The default value for LSAs is 50,000 LSAs. You can customize the default values.

Deprecation of Weak Ciphers

The minimum RSA key pair size must be 2048 bits. The compliance shield on the device must be disabled using the crypto engine compliance shield disable command to use the weak RSA key.

Programmability

  • gNMI Dial-Out Telemetry

  • PROTO Encoding

  • YANG Data Models

The following programmability features are introduced in this release:

  • gNMI Dial-Out Telemetry: This feature introduces a tunnel service for gNMI dial-out connections. Using this feature, you can use the device (that acts as a tunnel client) to dial out to a collector (that acts as a tunnel server). The tunnel server forwards requests from gNMI or gNOI clients.

    (Network Essentials)

  • PROTO Encoding: gNMI protocol supports PROTO encoding. The gnmi.proto file represents the blueprint for generating a complete set of client and server-side procedures that instantiate the framework for the gNMI protocol.

  • YANG Data Models: For the list of Cisco IOS XE YANG models available with this release, navigate to: https://github.com/YangModels/yang/tree/master/vendor/cisco/xe/17111.

    (Network Advantage)

show aaa dead-criteria radius enhancement command

The show aaa dead-criteria radius enhancement command allows you to use the configured radius server name as the input to identify the unique server in the server group and print the server dead criteria configuration.

show access-session command

The info keyword was introduced for the show access-session command.

Silent Host Handling

The silent-host-detection keyword was introduced for the following commands:

  • database-mapping

  • show lisp instance-id ipv4 database

  • show lisp instance-id ipv6 database

  • show lisp instance-id ipv4 server

  • show lisp instance-id ipv6 server

TCN Flood

The no ip igmp snooping tcn flood command was introduced to disable the flooding of multicast traffic during a spanning-tree Topology Change Notification (TCN) event on STP non-edge ports. STP Edge Ports do not flood multicast traffic during a spanning-tree Topology Change Notification (TCN) event.

New on the WebUI

There are no new WebUI features in this release.

Hardware and Software Behavior Changes in Cisco IOS XE Dublin 17.11.1

Behavior Change

Description

Deprecation of snmp-server enable traps license global configuration command

The command was deprecated. The associated MIB, CISCO-LICENSE-MGMT-MIB, is also no longer supported. In place of the deprecated command and unsupported MIB, use CISCO-SMART-LIC-MIB.

New flag for the IPv6 SGACL monitor mode

A new flag has been introduced for the IPv6 SGACL monitor mode. This was introduced to address hardware limitation of a single counter shared for IPv4 and IPv6 traffic. The HW_Monitor counter gets incremented irrespective of the type of traffic, which in turn updates the monitor mode flag. With a separate flag for IPv6 and IPv4 SGACL monitor mode, only the corresponding protocol flag is updated depending on the type of traffic.

show power and show power detail command output

The show power and show power detail command outputs are modified to display the correct power information of the standby switch.
