Spanning tree MST Cisco vs HP

[bee7ch]

Hello,

I got the core network based on Nexus 3548 and access switches based on 2960 and HP3500

Here is my vision of STP MST configuration on the devices without vlan load balancing:

Is everything correct ? Or I missed something ?

In the edge of network I have 15x HP 3500 and 7x 2960.

Configs:

Nexus1:
spanning-tree mode mst
spanning-tree mst configuration
name LMUA
revision 1
instance 0 vlan 1-4094
spanning-tree mst 0 root primary
interface po17
spanning-tree mst 0 port-priority 32
interface po31
spanning-tree mst 0 port-priority 32
interface po19
spanning-tree mst 0 port-priority 32
 
Nexus2:
spanning-tree mode mst
spanning-tree mst configuration
name LMUA
revision 1
instance 0 vlan 1-4094
spanning-tree mst 0 root secondary
interface po17
spanning-tree mst 0 port-priority 32
interface po31
spanning-tree mst 0 port-priority 32
interface po19
spanning-tree mst 0 port-priority 32
 
Access switches 2960:
spanning-tree mode mst
spanning-tree mst configuration
name LMUA
revision 1
instance 0 vlan 1-4094
interface po1
spanning-tree mst 0 port-priority 32
 
HP:
spanning-tree mode mst
name LMUA
revision 1
instance 0 vlan 1-4094
spanning-tree Trk1 priority 32

Thanks in advance,

Dmytro

Everything seems ok to me. Although port-priority commands on Nexuses are unnecessary.

Спасибо, буду пробовать :))

And in case of load-balancing the configuration will be like this or I missed something?

**************
Nexus1:
spanning-tree mode mst
spanning-tree mst configuration
name LMUA
revision 1
instance 1 vlan 1,3,6,8,20,30,37,60,101,200,300
instance 2 vlan 2,5,7,15,21,36,40,100,110,201,2000
spanning-tree mst 0 root primary
spanning-tree mst 1 priority 24576
spanning-tree mst 2 priority 28672

**************
Nexus2:
spanning-tree mode mst
spanning-tree mst configuration
name LMUA
revision 1
instance 1 vlan 1,3,6,8,20,30,37,60,101,200,300
instance 2 vlan 2,5,7,15,21,36,40,100,110,201,2000
spanning-tree mst 0 root secondary
spanning-tree mst 1 priority 28672
spanning-tree mst 2 priority 24576

The main question how should I config my access switches in this case?

Thanks,

I think you need the spanning-tree mst cost commands that you need to use in your case
