Hi,
  • you should first enable auto-bind, then add ports to the VLAN
  • on EXOS, RSTP needs a tag definition (implicitely taken from the VLAN if this has a specific tag), and it needs an untagged VLAN on every port
You did not define a tag for the rstp-test VLAN.

Hi Ahmed,

please take a look at the GTAC Knowledge article How to configure RSTP in EXOS.

The auto-bind feature works for ports that are added to the VLAN after auto-bind has been enabled, thus you might need to add some ports manually. You can use "show stpd s0 ports" to verify which ports are configured for spanning tree.

You need an untagged VLAN on any port participating in RSTP on EXOS, if you want to tagg all VLANs on that port you need to use MSTP instead. (Note that MSTP is compatible with RSTP.)

Best regards,
Erik

my config on extreme

Slot-1 Stack.6 # create vlan vlan100 tag 100
Slot-1 Stack.7 # configure "vlan100" add ports 1:1-6 tagged
Slot-1 Stack.8 # configure "vlan100" add ports 1:7-10 untagged

configure stpd s0 mode dot1w
enable stpd s0 auto-bind vlan "vlan100"
enable stpd "s0"

save
