I'm working on managing a ruckus network of 15 switches and trying to configure and optimize spanning tree.
i'm cisco trained and understand how to do it well on that platform. finding the ruckus version to be kind of confusing.
in the environment here i have uplinks connected to other switches, all of them on the 1/3/1-4 ports
i've got a bunch of ubiquti wireless on the 1/1/23 or 24 ports, the rest are computer device ports, edge ports.
i don't want spanning tree enabled on the edge ports, just the uplinks.
i've got a handful of vlans so vlan config looks something like this:
vlan 33 name Camera1 by port
tagged ethe 1/1/12 ethe 1/1/24 ethe 1/3/1 to 1/3/2
spanning-tree 802-1w
on 1/3/1
interface ethernet 1/3/1
port-name IDF11
optical-monitor
spanning-tree 802-1w admin-pt2pt-mac
interface ethernet 1/1/12
spanning-tree 802-1w admin-edge-port
no inline power
stp-bpdu-guard
show 802-1w vlan 33
Num Cost Mac Port ted cost bridge
1/1/12 128 20000 F T DESIGNATED FORWARDING 0 0000903a72282e80
we don't define 'edge ports' in cisco and conceptually i understand what an edge port is but what is this actually doing?
in addition to that what do these do?
#fast
port-span Fast spanning tree for end station ports
uplink-span Fast spanning tree for uplink ports
for example, this is so much simpler. can someone point out the differences?
interface GigabitEthernet0/1
switchport mode trunk
exit
interface GigabitEthernet0/2
switchport mode access
spanning-tree portfast <-- disables stp, sets designated forwarding
spanning-tree bpduguard enable <-- disables port if bpdu received
exit

If all switches are cascaded as you are showing, there wont be a loop. No matter who the root is. Probably the new switch B has a lower bridge id, which makes it the root bridge for VLAN 5. Check whats the priority for that switch in vlan 5, and if its too low cahnge it to something higher than the one in Core switch
