Cisco NCS 560-4 Router Overview
Real time DOM data is collected from SFPs, SFP+, periodically and compared with warning and alarm
threshold table values.
The DOM data collected are transceiver transmit bias current, transceiver transmit power, transceiver receive
power, and transceiver power supply voltage.
RSP Modules (N560-4-RSP4 and N560-4-RSP4E)
The Cisco NCS 560-4 router supports both, N560-4-RSP4 and N560-4-RSP4E. Each RSP has 32GB CPU
memory.
When redundant RSPs are installed, the control and data plane are 1:1 redundant and the standby RSP
components are in hot-standby state, ready to take over as active in the event of a failover.
Note
A failover indicates a failure in the software or in the card due to reasons, such as RSP card OIR, host kernel
crash or virtual machine crash triggering heartbeat failure.
Whereas, switchover is a graceful operator-initiated task that leads to the RSP being brought down.
The RSP modules handle the data plane, network timing, and control plane functionalities for the router. The
RSP configuration allows you to use Cisco IOS XR software to control chassis management, redundancy,
external management, and system status indications on the router.
RSP features include:
• Redundant RSP management—The RSP manages detection of RSPs, exchange of health and status
• Traffic management, including buffering, queuing, and scheduling, Ethernet MAC functions
• Network clocking functions including phase and time-of-day for BITS, 1 PPS, 10 MHz, and 1588 PTP
• Storage of software images, system configuration, and SysLog
• In Service Software Upgrade (ISSU) capability with zero topology loss and minimum packet loss (50
• External management interfaces (RS232 console, management ENET, USB console, USB storage) and
• Centralized data plane, timing, and control plane functions for the system
• High-level control of interface modules
• Management functionalities for the router
• Control plane (host) CPU and associated memory in which IOS-XR and platform control software runs
Note
If your system includes redundant RSPs, both RSPs should be of the same type and have the same memory
size. We strongly recommend that you avoid configuring your router using mixed route processor cards.
