The RSTP component avoids this delay by calculating an alternate root port, and immediately switching over to the alternate port if the root port becomes unavailable. Thus, using RSTP, the switch immediately brings the alternate port to forwarding state, without the delays caused by the listening and learning states. The RSTP component conforms to IEEE standard 802.1D 2004. RSTP enhancements is a set of functions added to increase the volume of RSTP in Mellanox switches. It adds a set of capabilities related to the behavior of ports in different segments of the network. For example: the required behavior of a port connected to a non-switch entity, such as Mellanox Technologies 70 Mellanox Technologies Confidential

Spanning Tree

The operation of Rapid Spanning Tree Protocol (RSTP) provides for rapid recovery of connectiv-

ity following the failure of a bridge/bridge port or a LAN. The RSTP component avoids this

delay by calculating an alternate root port, and immediately switching over to the alternate port if

the root port becomes unavailable. Thus, using RSTP, the switch immediately brings the alternate

port to forwarding state, without the delays caused by the listening and learning states. The RSTP

component conforms to IEEE standard 802.1D 2004.

RSTP enhancements is a set of functions added to increase the volume of RSTP in Mellanox

switches. It adds a set of capabilities related to the behavior of ports in different segments of the

network. For example: the required behavior of a port connected to a non-switch entity, such as

switch (config vlan 10) # exit

switch (config) #

switch (config) # interface ethernet 1/35

switch (config interface ethernet 1/35) #

switch (config interface ethernet 1/35) # switchport mode hybrid

switch (config interface ethernet 1/35) #

switch (config interface ethernet 1/35) # switchport hybrid allowed-vlan add 10

switch (config interface ethernet 1/35) #

switch (config interface ethernet 1/35) # exit

switch (config) #

switch > enable

switch # configure terminal
