AMF Introduction and Configuration
118 New and Enhanced Features in AlliedWare Plus 5.4.4 Major and Minor Versions
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.* these being 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, one or more external NTP servers must be configured on the network, and
every node on the network must be configured to use the external server or servers.
Alternatively, you can configure an AlliedWare Plus device as the NTP master, but this NTP
master must not be a member of the AMF network. Otherwise, NTP synchronisation
issues can occur.
To configure an AlliedWare Plus device as an NTP master, use the command:
The primary function of NTP within an AMF network is to ensure that time and date
stamps on backups are consistent across member nodes within the backup. This is
particularly important in an AMF network that has multiple AMF master nodes, to ensure
that node recovery is performed with the most up-to-date backup.
Configuring NTP on the AMF network
Before you configure NTP on the AMF network, we recommend setting all nodes in the
network to the same time, date, and timezone, to ensure NTP synchronisation. To do this,
create an AMF working-set of the whole network and set the date and time, for example:
Once you have configured all nodes with the same time, date and timezone, configure the
working-set of all nodes with the IP address of the NTP server, for example:
Note
The AMF control VLANs and AMF management subnets can be manually
changed.
