What's New in Software for Cisco IOS XE Dublin 17.12.1

Feature Description

Carrier Ethernet

Service Instance as Track Client

Track can be configured to check for reachability to IBR(Upstream router). If IBR is not reachable, the service instance is kept in admin down state. This avoids traffic drop until the route is installed which optimizes the convergence. Currently, IOS XE platforms do not have options to shutdown EFP based on track reachability.

CEM

BGP PIC with CEM

BGP PIC extends support to TDM CEM pseudowire to facilitate faster, sub-second BGP convergence and to improve fast failover.

CEM Description Command

You can add description for a cem group up to 200 characters using the description command.

DCC CLNP Interworking

This feature enables you to exchange Network Management System (NMS) management traffic between OSI Data Communication Channel (DCC) and Ethernet ports over Connectionless Network Protocol (CLNP) interworking. With this, you can maintain in-band communication between old Add/Drop Multiplexer (ADM) equipments to be managed from NMS.

Layer 2

MACsec support with PTP for 1GE A900-IMA8CS1Z-M Interface Module

You can now configure MACsec support with Precision Time Protocol (PTP) packets for mitigating security vulnerabilities on a router.
