AMF external removable media
All AMF master nodes require external storage media (e.g. USB memory stick, SD card) to
be installed. This external storage is used to hold a backup of all relevant files from all
nodes within the AMF network, including other master nodes, so it must be large enough
to be able to accommodate all of the backed up files. Files that are backed up include all
configuration files, release files, and scripts, but not core dumps, exception logs, or
technical support files.
Typically a 4GB capacity external media device would be of sufficient size to hold backups
for a 40 node AMF network.
AMF interaction with QoS and ACLs
It's important that ACL and QoS rules do not block any traffic on VLANs 4091 and 4092
because they are the default AMF control VLANs. Similarly, ACL and QoS rules should not
block any Layer 3 traffic on 172.31.0.* or 172.31.128.* as these are the default AMF
management traffic subnets. Packets with protocol type 0xfbae and BPDU packets that
use the MAC address: 0180.c200.002e should also not be blocked.
NTP and AMF
AMF uses NTP to synchronize the system clocks across nodes within the network. For this
to operate there must either be one or more external NTP servers configured on the
network, or one single AMF node must be configured as the NTP 'master' using the

Note
The AMF control VLANs and AMF management subnets can be manually
changed
Note
It is invalid to have an NTP master configured on an AMF node anywhere in the
network if any external NTP servers exist, because this will prevent clock
synchronization.
