AMF AND AMF PLUS COMMANDS
SWITCHPORT
ATMF-CROSSLINK
switchport atmf-crosslink
Overview This command configures the selected port, statically aggregated link or dynamic
channel group (LACP) to be an AMF crosslink. Running this command will
automatically place the port or aggregator into trunk mode (i.e. switchport mode
trunk).
The connection between two AMF masters must utilize a crosslink. Crosslinks are
used to carry the AMF control information between master nodes. Multiple
crosslinks can be configured between two master nodes, but only one crosslink
can be active at any particular time. All other crosslinks between masters will be
placed in the blocking state, in order to prevent broadcast storms.
Note that AlliedWare Plus CentreCOM Series switches are AMF Edge nodes and do
not support virtual links or crosslinks. This is because each edge node can only
have a single physical AMF link.
Use the no variant of this command to remove any crosslink that may exist for the
selected port or aggregated link.
Syntax
switchport atmf-crosslink
no switchport atmf-crosslink
Mode Interface Configuration for a switchport, a static aggregator or a dynamic channel
group.
Usage notes Crosslinks can be used anywhere within an AMF network. They have the effect of
separating the AMF network into separate domains.
Where this command is used, it is also good practice to use the switchport trunk
native vlan command with the parameter none selected. This is to prevent a
network storm on a topology of ring connected devices.
Example 1 To make switchport port1.0.1 an AMF crosslink, use the following commands:
Node_1# configure terminal
Node_1(config)# interface port1.0.1
Node_1(config-if)# switchport atmf-crosslink
Example 2 This example is shown twice. Example 2A is the most basic command sequence.
Example 2B is a good practice equivalent that avoids problems such as broadcast
storms that can otherwise occur.
Example 2A To make static aggregator sa1 an AMF crosslink, use the following commands:
Node_1# configure terminal
Node_1(config)# interface sa1
Node_1(config-if)# switchport atmf-crosslink
