Hi Im pretty confused with the way how to configure Per vlan spanning tree on XOS because of the way extreme uses spanning tree domains. Can someone please post a sample configuration on how it would look if you would want RSTP betwen a cisco and a extreme summit switch? (from Samueltechking)

Its been a while since you posted this, but you could try setting the encapsulation mode of the port connecting to Cisco as pvst-plus?
* X250e-24p.2 # con add ports [u]
Execute the command
dot1d 802.1d mode
emistp EMISTP mode
pvst-plus PVST-Plus mode (from Shashank_S Kumar)

Hey Merab,

Below is example of dot1w interoperability with Cisco:

Extreme Configuration (EXOS)

configure vlan test add port 3 tagged

conf vlan "Default" del port 3

create stpd domain_test

conf stpd "domain_test" add vlan "test" ports 1,3 pvst-plus

conf stpd "domain_test" tag 10

con stpd "domain_test" mode dot1w

conf stpd "domain_test" default-encapsulation pvst-plus

conf stpd "domain_test" ports link-type point-to-point 1,3

enable stpd "domain_test"

disable edp port 3

[i] Cisco Configuration (IOS)

interface gigabitEthernet 0/3

no cdp enable
