atmf management subnet
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 internodal 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.
Syntax atmf management subnet <a.b.0.0>
no atmf management subnet
Default
172.31.0.0 (Note that a subnet 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.
Parameter Description
amf management subnet A subnet that is assigned for AMF management
purposes.
<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 to 172.31.255.255, or 192.168.0.0 as
defined in RFC1918.
