Configure NEM24p-0

1. Start the configuration with all ports and the default VLAN shut down.

   Also, enable the Uplink port trailing feature.

   ---

   Tip  - It is a best practice to start the configuration with all the ports and default VLAN shut down. Disable GVRP and GMRP, because dynamic VLAN learning is not suggested.

   NEM24p-0 SEFOS# configure terminal
   NEM24p-0 SEFOS(config)# set gvrp disable
   NEM24p-0 SEFOS(config)# set gmrp disable
   NEM24p-0 SEFOS(config)# set port-channel enable
   NEM24p-0 SEFOS(config)# set uplink-trailing enable
   % Enabling Uplink Trailing Module 
   NEM24p-0 SEFOS(config)# interface vlan 1
   NEM24p-0 SEFOS(config-if)# shutdown
   NEM24p-0 SEFOS(config-if)# no ip address
   NEM24p-0 SEFOS(config-if)# exit
   NEM24p-0 SEFOS(config)# interface range extreme-ethernet 0/1-24
   NEM24p-0 SEFOS(config-if-range)# shutdown
   NEM24p-0 SEFOS(config-if-range)# end
   

2. Create and enable port-channel between switches according to the topology.

   NEM24p-0 SEFOS# configure terminal
   NEM24p-0 SEFOS(config)# interface port-channel 12
   NEM24p-0 SEFOS(config-if)# no shutdown
   NEM24p-0 SEFOS(config-if)# exit
   NEM24p-0 SEFOS(config)# end
   

3. Configure VLANs manually.

   You must add at least one port to the VLAN before you can assign the VLAN a name.

   NEM24p-0 SEFOS# configure terminal
   NEM24p-0 SEFOS(config)# vlan 300
   NEM24p-0 SEFOS(config-vlan)# ports add port-channel 12 name vlan-1
   NEM24p-0 SEFOS(config-vlan)# vlan active
   NEM24p-0 SEFOS(config-vlan)# exit
   NEM24p-0 SEFOS(config)# vlan 301
   NEM24p-0 SEFOS(config-vlan)# ports add port-channel 12 name vlan-2
   NEM24p-0 SEFOS(config-vlan)# vlan active
   NEM24p-0 SEFOS(config-vlan)# exit
   NEM24p-0 SEFOS(config)# end
   

4. Create an uplink trailing group.

   The group number can be 1 to 65355.

   NEM24p-0 SEFOS# configure terminal
   NEM24p-0 SEFOS(config)# uplink-trailing 10
   %  Uplink Trailing Group 10 Created
   NEM24p-0 SEFOS(config-ultr)# description "Uplink-trailing between NEM24p-0 & ToR72p -1"
   NEM24p-0 SEFOS(config-ultr)# end
   

5. Configure the port-channel to allow all VLANs.

   NEM24p-0 SEFOS# configure terminal
   NEM24p-0 SEFOS(config)# interface port-channel 12
   NEM24p-0 SEFOS(config-if)# switchport mode trunk
   NEM24p-0 SEFOS(config-if)# exit
   NEM24p-0 SEFOS(config)# end
   

6. Enable the ports and add them to the appropriate port-channels.

   Assign the ports to the uplink-trailing group as uplink or downlink to bind them together

   NEM24p-0 SEFOS# configure terminal
   NEM24p-0 SEFOS(config)# interface range extreme-ethernet 0/1
   NEM24p-0 SEFOS(config-if-range)# description "connected to ToR72p-1"
   NEM24p-0 SEFOS(config-if-range)# channel-group 12 mode active
   NEM24p-0 SEFOS(config-if-range)# uplink-trailing group 10 uplink
   NEM24p-0 SEFOS(config-if-range)# no shutdown
   NEM24p-0 SEFOS(config-if-range)# exit
   NEM24p-0 SEFOS(config)# interface extreme-ethernet 0/18
   NEM24p-0 SEFOS(config-if)# description "connected to Linux blade, Host-2"
   NEM24p-0 SEFOS(config-if)# switchport mode trunk
   NEM24p-0 SEFOS(config-if)# uplink-trailing group 10 downlink
   NEM24p-0 SEFOS(config-if)# no shutdown
   NEM24p-0 SEFOS(config-if)# exit
   NEM24p-0 SEFOS(config)# end
   

7. Save the configuration.

   NEM24p-0 SEFOS# copy run start
