External switch configuration
The external switch requires the following configuration settings. Example
commands are shown for an HP procurve 3500yl switch with interfaces A1 and A4
connected to the FortiSwitch-5003A boards. This external switch acts as the root
for spanning tree instance 0.
1 Create an MSTP configuration that includes a name and a revision. For example,
if the name is tree_1 and the revision is 11:
spanning-tree config-name "tree_1"
spanning-tree config-revision 1
2 Configure the switch to add VLAN tag 100 to packets from the internal network
and VLAN tag 101 to packets from the external network and to send packets from
both networks to the FortiSwitch-5003A board.
vlan 100
name "VLAN100"
tagged 6,8,19,A1,A4
exit
vlan 101
name "VLAN101"
tagged 5,7,20,A1,A4
no ip address
exit
3 Add spanning tree instance 3 for packets from the internal network. Add VLAN tag
100 to this spanning tree instance. Set the priority of this spanning tree instance to
5.
spanning-tree instance 3 vlan 100
spanning-tree instance 3 priority 5
