cost <value>
point-to-point
port-priority <value>
portfast
vlan <vlan-id>
cost <value>
port-priority <value>
vlan range <WORD>
NOTE: RSTP is backward compatible with STP and is enabled by default. For clarity, this RSTP command uses the spanning tree
keyword.
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
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:
l Fast Ethernet 10Mbs—100
l Fast Ethernet 100Mbs—19
l 1Gigabit Ethernet—4
l 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

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:
l FastEthernet IEEE 802.3—fastethernet
