Extreme Summit X440 to Cisco Catalyst C2960X Spanning tree

[Edgar_Dattoli]

Hi.
I need to add and connect a X440 stack to an on-production Cisco switch ring.
Somebody can help me to know the right spanning tree configuration for the X440 to be compatible with the existing Cisco spanning tree configuration?
This is the spanning tree an uplink interfaces config at the Cisco switches:

spanning-tree mode rapid-pvstspanning-tree loopguard default
spanning-tree portfast default
spanning-tree extend system-id
spanning-tree vlan 1-4094 priority 61440

interface GigabitEthernet1/0/25
switchport mode trunk
switchport nonegotiate
load-interval 30
storm-control broadcast level 30.00
end

interface GigabitEthernet1/0/26
switchport mode trunk
switchport nonegotiate
load-interval 30
storm-control broadcast level 30.00
end

Exos version: 15.3.1.4

Thanks!

1.Yes the Extreme XOS configuration I provided is compatible with "spanning-tree mode rapid-pvstspanning-tree" on the Cisco side.

2. VLAN 10 in the example is the carrier VLAN for STPD "domain_test".

3. You should be able to add additional VLANs to same stpd using the command:
configure stpd "domain_test" add vlan ports pvst-plus

Must I specify the carrier VLAN at the Cisco configuration?

[Dorian_Perry]

VLAN 10 does not need to be created at all. The carrier VLAN can be an existing VLAN of your choosing.
See GTAC Knowledge article: What is a STP Carrier vlan?

Must I create the VLAN 10 (carrier VLAN) on all the CISCO Switches, or just in the CISCO Switches near to the X440 (Neighbors) ?
