The Logical Management IP Interface is a virtual management IP interface. Configure the Logical Management IP Interface using the CLI syntax described in this section.

Note

A Logical Management Interface must include both physical management interfaces. Therefore, it should contain all four interfaces. Otherwise, this will result in a confd restart and ahealthcheck timeout (system down time) if the physical interface underlying the logical interface goes down.


Command Syntax

% set system logicalMgmtIpInterface <intfc_name>
	ipAddress <ip address>
	mgmtIpInterfaceGroupName <name>
	snmpListenOnlyOnThisInterface <false | true>
	state <disabled | enabled>
	useIpAddrAsSnmpSource <false | true>

Command Parameters

Parameter

Description

ipAddress

The logical IP address of the interface. The following IP address types are supported:

  • IPv4 – Uses dotted decimal format (for example 128.127.50.224).
  • IPv6 – Uses hexadecimal/colon format (for example, 1280:1276:3350:2224:2222:3333:8888:1245 or fd00:21:445:128::7880).

logicalMgmtIpInterface

The logical management IP interface name.

mgmtIpInterfaceGroupName

The name of the management IP interface group used by this logical IP interface.

snmpListenOnlyOnThisInterface

When this flag is set to True, and the flag "useIpAddrAsSnmpSource" is also set as True, the SBC receives SNMP requests only on this logical management IP address.

The options are:

  • false (default)
  • true

Note:

  • When this flag is set to True, and the flag useIpAddrAsSnmpSource is also set as True, the source address of all traps is the logical IP Address.
  • You cannot use this feature in cloud deployments where the SBC automatically registers to the EMS. This is because the EMS uses the SBC mgt0 IP used during the registration to check the reachability of the SBC. If the logic IP is only being used, then the EMS will not be able to reach the SBC and it will be marked offline.

state

Administrative state of the logical management IP interface.

  • disabled (default) – The logical management IP address is not being used for chassis management.
  • enabled – The logical management IP address is being used for chassis management.

useIpAddrAsSnmpSource

Set this flag to “true” to receive SNMP requests on this logical management IP address. Without snmpListenOnlyOnThisInterface also set to True, the source of the traps is not necessarily this address. 

  • false (default)
  • true

Note:

  • You can only enable this flag on one logical management interface at a time.
  • When using this feature in a cloud deployment where the SBC automatically registers to the EMS, a static route needs to be configured. For more information, refer to Management Static Route - CLI.
    This allows the SBC to send the message from a mgmt interface that the EMS recognizes. For deployments where the SBC is manually configured in the EMS, the static route is not required because the EMS can be provisioned to know about alternate SBC IPs.

Command Example

To display the logical management IP interface configuration:

% show system logicalMgmtIpInterface LogMgmt  
	mgmtIpInterfaceGroupName mgmtGroup;  
	ipAddress 3FFE:1900:4545:3:200:F8FF:FE21:67CF;  
	state enabled;
	useIpAddrAsSnmpSource true;
	snmpListenOnlyOnThisInterface true;

To display the logical management IP interface configuration for two subnets:

 % show system logicalMgmtIpInterface 
	logicalMgmtIpInterface AGMGM { 
		mgmtIpInterfaceGroupName mgmtGroup1; 
		ipAddress 10.xx.xx.50; 
		state enabled;
		useIpAddrAsSnmpSource disabled;
	} 
	logicalMgmtIpInterface HAMGM { 
		mgmtIpInterfaceGroupName mgmtGroup; 
		ipAddress 10.xx.xx.65; 
		state enabled; 
		useIpAddrAsSnmpSource disabled;
	}

 

Note

When configuring the management interfaces on two subnets, a logical management IP interface is needed for each subnet.
