Step 4. Change back to config mode. Run:

Step 5. Enter the interface context. Run:

Step 6. From within the interface context, configure the interface mode to Hybrid. Run:

Step 7. From within the interface context, configure the allowed VLAN membership. Run:

Step 8. Change to config mode again. Run:

5.4 MAC Address Table

5.4.1 Configuring Unicast Static MAC Address

You can configure static MAC addresses for unicast traffic. This feature improves security and

reduces unknown unicast flooding.

 To configure Unicast Static MAC address:

Step 1. Log in as admin.

Step 2. Enter config mode. Run:

Step 3. Run the command

mac-address-table static unicast <destination mac address> vlan <vlan

identifier(1-4094)> interface ethernet <slot>/ <port>

5.5 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

switch (config) # mac-address-table static unicast 00:11:22:33:44:55 vlan 1 interface
