Description
Dell’s RSTP implementation interoperates with both PVST (Per VLAN Spanning Tree 802.1D) and Rapid-PVST
(802.1w) implementation on industry-standard router/switches. Syntax
Usage Guidelines
Dell supports global instances of RSTP and PVST+. Therefore, the ports on industry-standard routers/switches
must be on the default or untagged VLAN for interoperability with controllers.
ArubaOS supports RSTP on the following interfaces:
z FastEthernet IEEE 802.3—fastethernet
z Gigabitethernet IEEE 802.3—gigabitethernet
z Port Channel ID—port-channel
Note: RSTP is backward compatible with STP and is enabled by default. For clarity, this RSTP command uses the spanning tree
keyword.
Parameter Description Range Default
cost <value> Enter the spanning tree path cost. Use the
cost values to determine the most
favorable path to a particular destination:
the lower the cost, the better the path
1 - 65535 Default: Based on Interface type:
z Fast Ethernet 10Mbs—100
z Fast Ethernet 100Mbs—19
z 1Gigabit Ethernet—4
z 10 Gigabit Ethernet—2
point-to-point Set the interface to a point-to-point n/a Enabled
port-priority
<value>
Change the spanning tree priority. 0 - 255 128
portfast Change from blocking to forwarding n/a Disabled
vlan <vlan-id> Enter the keyword vlan followed by the
VLAN-ID
n/a —
cost <value> Enter th keyword cost followed by the
cost value to change the interface’s
spanning tree path cost.
1 - 65535
port-priority
<value>
Change the spanning tree priority. 0 - 255 128
vlan range <WORD> Enter the keywords vlan range followed
by the range of VLAN iID’s. Separate the
VLAN IDs with a hyphen, comma or both
to indicate the range.
For example: 2-3 or 2,4,6 or 2-6,11
