Configuring auto topology
Use the auto topology feature to automatically form an inter-switch link (ISL) between two switches. You need to enable the feature and specify the mgmt-vlan. The mgmt-vlan is the VLAN to use for the native VLAN on ISL ports and the native VLAN on the internal switch interface.
NOTE: Do not use the same VLAN for the mgmt-vlan and an existing switch virtual interface (SVI).
config switch auto-network
set mgmt-vlan <1-4094>
set status {enable | disable}
end
For example:
config switch auto-network
set mgmt-vlan 101
set status enable
end
config switch interface
edit "internal"
set native-vlan 101
set allowed-vlans 100-102,4094
set stp-state disabled
set snmp-index 53
next
end
