Where this command is used, it is also good practice to use the switchport trunk native
vlan command with its parameter “none” selected. This is to prevent a network storm on a
topology of ring connected switches.
Example-1 To make a switchport 1.0.1 an AMF crosslink, use the following commands:
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:
Example-2B To make static aggregator sa1 an AMF crosslink, use the following commands for good
practice:
In this example VLAN 2 is assigned to the static aggregator, and the native VLAN (VLAN 1)
is explicitly excluded from the aggregated ports and the crosslink assigned to it.
