Management Plane Protection Commands

This module describes the commands used to configure management plane protection (MPP).

For detailed information about management plane protection concepts, configuration tasks, and examples, see the Implementing Management Plane Protection chapter in the System Security Configuration Guide for Cisco ASR 9000 Series RoutersSystem Security Configuration Guide for Cisco 8000 Series Routers .

address ipv4 (MPP)

To configure the peer IPv4 or IPv6 address in which management traffic is allowed on the interface, use the address ipv4 command in interface peer configuration mode. To remove the IP address that was previously configured on this interface, use the no form of this command.

address {ipv4 | ipv6} peer-ip-address |peer-ip-address/ length

no address {ipv4 | ipv6} peer-ip-address| peer-ip-address/ length

Syntax Description

peer-ip-address

(Required) Peer IPv4 or IPv6 address in which management traffic is allowed on the interface. This address can effectively be the source address of the management traffic that is coming in on the configured interface.

peer ip-address/length

(Required) Prefix of the peer IP address and IPv4 address or IPv6 format:

  • IPv4—A.B.C.D/length
  • IPv6—X.X:X.X

Command Default

If no specific peer is configured, all peers are allowed.

RP/0/RP0RSP0/CPU0:router(config-telnettftp-peer)# address ipv4 10.1.0.0/16

address ipv6 (MPP)

To configure the peer IPv6 address in which management traffic is allowed on the interface, use the address ipv6 command in interface peer configuration mode. To remove the IP address that was previously configured on this interface, use the no form of this command.

address ipv6 {peer-ip-address | peer-ip-address/ length}

Syntax Description

peer-ip-address

Peer IPv6 address in which management traffic is allowed on the interface. This address can effectively be the source address of the management traffic that is coming in on the configured interface.

speer ip-address/length

Prefix of the peer IPv6 address.

Command Default

If no specific peer is configured, all peers are allowed.

Examples

The following example shows how to configure the peer IPv6 address 33::33 for management traffic: 


RP/0/RP0RSP0/CPU0:router# configure
RP/0/RP0RSP0/CPU0:router(config)# control-plane
RP/0/RP0RSP0/CPU0:router(config-ctrl)# management-plane
RP/0/RP0RSP0/CPU0:router(config-mpp)# inband
RP/0/RP0RSP0/CPU0:router(config-mpp-inband)# interface HundredGigabitEthernet 0/1/1/2
RP/0/RP0RSP0/CPU0:router(config-mpp-inband-if)# allow TFTP peer
RP/0/RP0RSP0/CPU0:router(config-tftp-peer)# address ipv6 33::33

allow

To configure an interface as an inband or out-of-band interface to allow all peer addresses for a specified protocol or all protocols, use the allow command in management plane protection inband interface configuration mode or management plane protection out-of-band interface configuration.

To disallow a protocol on an interface, use the no form of this command.

allow {protocol | all} [peer]

no allow {protocol | all} [peer]

Syntax Description

protocol

Interface configured to allow peer-filtering for the following specified protocol’s traffic:

  • HTTP(S)
  • NETCONF (version 1.1 protocol)
  • SNMP (also versions)
  • Secure Shell (v1 and v2)
  • TFTP
  • Telnet
  • XML

all

Configures the interface to allow peer-filtering for all the management traffic that is specified in the list of protocols.

peer

(Optional) Configures the peer address on the interface. Peer refers to the neighboring router interface in which traffic might arrive to the main router.

Command Default

By default, no management protocol is allowed on any interface except the management interfaces.

Command Modes

Management plane protection inband interface configuration

Command History

Release

Modification

Release 7.0.12

This command was introduced.

Usage Guidelines

If you permit or allow a specific protocol to an interface, traffic is allowed only for that protocol, and all other management traffic is dropped.

The IOS XR XML API provides a programmatic interface to the router for use by external management applications. This interface provides a mechanism for router configuration and monitoring utilizing XML formatted request and response streams. As one of the management services, XML should be capable of applying MPP. To secure XML MPP data, XML keyword has been added to the command.

Out-of-band refers to an interface that allows only management protocol traffic to be forwarded or processed. An out-of-band management interface is defined by the network operator to specifically receive network management traffic. The advantage is that forwarding (or customer) traffic cannot interfere with the management of the router.

vrf vrf-name

no vrf vrf-name

Syntax Description

vrf-name

Name assigned to a VRF.

Command Default

The VRF concept must be used to configure interfaces as out-of-band. If no VRF is configured during an out-of-band configuration, the interface goes into a default VRF.
