atmf management subnet
Overview
This command is used to assign a subnet that will be allocated to the AMF
management and domain management VLANs. From the address space defined
by this command, two subnets are created, a management subnet component
and a domain component, as explained in the Usage section of this command
description.
AMF uses these internal IPv4 subnets when exchanging its inter nodal status
packets. These subnet addresses must be reserved for AMF and should be used for
no other purpose.
The new management subnet will not become effective until all members of the
AMF network have been updated and all its units rebooted.
Use the
no
variant of this command to remove the assigned subnet VLANs.
Syntax
atmf management subnet
<a.b.0.0>
no atmf management subnet
Default
172.31.0.0. Asubnet mask of 255.255.0.0 will automatically be applied.
Mode
Global Configuration
Usage
Typically a network administrator would use this command to change the default
subnet address to match local network requirements.
As previously mentioned, running this command will result in the creation of a
further two subnets (within the class B address space assigned) and the mask will
extend from /16 to /17.
For example, if the management subnet is assigned the address 172.31.0.0/16, this
will result in the automatic creation of the following two subnets:
•
172.31.0.0/17 assigned to the
atmf management vlan
•
172.31.128.0/17 assigned to the
atmf domain vlan
.
Examples
To change the AMF management subnet address on node node-1 to 172.25.0.0:
node-1#
configure terminal
node-1(config)#
atmf management subnet 172.25.0.0
Parameter
Description
<a.b.0.0>
The IP address selected for the management subnet. Because a
mask of 255.255.0.0 (i.e. /16) will be applied automatically, an IP
address in the format a.b.0.0 must be selected.
Usually this subnet address is selected from an appropriate
range from within the private address space of 172.16.0.0 to
172.31.255.255, or 192.168.0.0 as defined in RFC1918.
