The Network Convergence System 5500 Series routers deliver a programmable, high-capacity and modular answer for Core, Peering, and WAN Transport deployments. Running the latest version of Cisco IOS XR Software, the 5500 Series supports segment routing, advanced forwarding feature sets, and programmable network management.

This series of routers deliver:

  • High-Performance, High-Density 100 Gb centric deployments

  • Option for redundant route processors, fabric cards, power modules and system controllers

  • Extreme focus on optimized power consumption in watts/Gbps

  • An infrastructure for hosting applications

  • Programmability with YANG model based APIs

The latest release of Cisco IOS XR operating system opens up the architecture of Cisco IOS XR using a 64-bit Linux-based operating system to deliver greater agility, automation and simplicity, while reducing cost of operating the networks.

Behavior Change Introduced in Cisco IOS XR Release 6.2.3

Locking a Running Configuration in NETCONF

For a NETCONF client to change a configuration in Cisco IOS XR, it is recommended for the client to acquire a lock to prevent simultaneous update from another NETCONF client or CLI session.

To acquire a configuration lock, the NETCONF client sends a RPC request to lock the running datastore. In Cisco IOS XR 6.1.x and previous releases, the RPC request candidate data-store was the target for acquiring the lock. But from release 6.2.x and later, the request running data-store must be sent to successfully lock the configuration.

Example: NETCONF request with running data-store as target to successfully lock a configuration:


<rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
       <lock>
         <target>
           <running/>                                                                                   
         </target>
       </lock>
</rpc> 

Interface Name Modified

Prior to IOS XR Release 6.2.1, 1 Gigabit Ethernet and 10 Gigabit Ethernet interfaces were both named as TenGigE. Also, 40 Gigabit Ethernet and 100 Gigabit Ethernet interfaces were both named as HundredGigE. From Release 6.2.1 onwards, the names have been modified to:

Interface Type

Interface Name

1 Gigabit Ethernet

GigabitEthernet

10 Gigabit Ethernet

TenGigE

40 Gigabit Ethernet

FortyGigE

100 Gigabit Ethernet

HundredGigE


Note

After upgrading to Release 6.2.3, the old configurations applied to 1G and 40G interfaces will not be available. Therefore you must reconfigure the 1G and 40G interfaces using the new names.

Important Notes

  • The offline diagnostics functionality is not supported in NCS 5500 platform. Therefore, the hw-module service offline location command will not work. However, you can use the (sysadmin)# hw-module shutdown location command to bring down the LC.

  • Flow-aware transport pseudowire feature is not supported.

  • Use show mrib route summary command to gather correct number of (S,G) routes.
