Configure Switch ES1-24p-1 for L2 PVRST LLA Active/Active on the Servers

Configure Switch `ES1-24p-1` for L2 PVRST LLA Active/Active on the Servers

Start the configuration with all ports and the default VLAN shutdown.

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

ES1-24p-1 SEFOS# configure terminal
ES1-24p-1 SEFOS(config)# set gvrp disable
ES1-24p-1 SEFOS(config)# set gmrp disable
ES1-24p-1 SEFOS(config)# interface vlan 1
ES1-24p-1 SEFOS(config-if)# shutdown
ES1-24p-1 SEFOS(config-if)# no ip address
ES1-24p-1 SEFOS(config-if)# exit
ES1-24p-1 SEFOS(config)# interface range extreme-ethernet 0/1-24
ES1-24p-1 SEFOS(config-if-range)# shutdown
ES1-24p-1 SEFOS(config-if-range)# end

Create and enable port-channels between switches per the topology.

See L2 and L3 Topology.

ES1-24p-1 SEFOS# configure terminal
ES1-24p-1 SEFOS(config)# interface port-channel 131
ES1-24p-1 SEFOS(config-if)# no shutdown
ES1-24p-1 SEFOS(config-if)# exit
ES1-24p-1 SEFOS(config)# interface port-channel 132
ES1-24p-1 SEFOS(config-if)# no shutdown
ES1-24p-1 SEFOS(config-if)# exit
ES1-24p-1 SEFOS(config)# interface port-channel 100

ES1-24p-1 SEFOS(config-if)# no shutdown
ES1-24p-1 SEFOS(config-if)# exit
ES1-24p-1 SEFOS(config)# end

Configure VLANs manually.

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

ES1-24p-1 SEFOS# configure terminal
ES1-24p-1 SEFOS(config)# vlan 300
ES1-24p-1 SEFOS(config-vlan)# ports add port-channel 131 name external-vlan-1
ES1-24p-1 SEFOS(config-vlan)# vlan active
ES1-24p-1 SEFOS(config-vlan)# exit
ES1-24p-1 SEFOS(config)# vlan 301
ES1-24p-1 SEFOS(config-vlan)# ports add port-channel 131 name external-vlan-2
ES1-24p-1 SEFOS(config-vlan)# vlan active
ES1-24p-1 SEFOS(config-vlan)# exit
ES1-24p-1 SEFOS(config)# vlan 302

ES1-24p-1 SEFOS(config-vlan)# exit
ES1-24p-1 SEFOS(config)# vlan 200
ES1-24p-1 SEFOS(config-vlan)# ports add port-channel 131  name internal-vlan-1
ES1-24p-1 SEFOS(config-vlan)# vlan active
ES1-24p-1 SEFOS(config-vlan)# exit
ES1-24p-1 SEFOS(config)# vlan 201
ES1-24p-1 SEFOS(config-vlan)# ports add port-channel 131  name internal-vlan-2
ES1-24p-1 SEFOS(config-vlan)# vlan active
ES1-24p-1 SEFOS(config-vlan)# exit
ES1-24p-1 SEFOS(config)# vlan 202
ES1-24p-1 SEFOS(config-vlan)# ports add port-channel 131  name internal-vlan-3
ES1-24p-1 SEFOS(config-vlan)# vlan active
ES1-24p-1 SEFOS(config-vlan)# exit
ES1-24p-1 SEFOS(config)# vlan 203
ES1-24p-1 SEFOS(config-vlan)# ports add port-channel 131  name internal-vlan-4
ES1-24p-1 SEFOS(config-vlan)# vlan active
ES1-24p-1 SEFOS(config-vlan)# end

Configure the port-channels to allow all VLANs.

ES1-24p-1 SEFOS# configure terminal
ES1-24p-1 SEFOS(config)# interface port-channel 131
ES1-24p-1 SEFOS(config-if)# switchport mode trunk
ES1-24p-1 SEFOS(config-if)# exit
ES1-24p-1 SEFOS(config)# interface port-channel 132
ES1-24p-1 SEFOS(config-if)# switchport mode trunk
ES1-24p-1 SEFOS(config-if)# exit
ES1-24p-1 SEFOS(config)# interface port-channel 100
ES1-24p-1 SEFOS(config-if)# switchport mode trunk
ES1-24p-1 SEFOS(config-if)# exit
ES1-24p-1 SEFOS(config)# interface port-channel 101
ES1-24p-1 SEFOS(config-if)# switchport mode trunk
ES1-24p-1 SEFOS(config-if)# exit
ES1-24p-1 SEFOS(config)# end

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

Configure the host port to allow all VLANs.

Configure the LLA role.

Specify the inter-switch link and port-channel connecting to host to be part of LLA.

Note - These settings take effect after saving the configuration and resetting SEFOS.

ES1-24p-1 SEFOS# configure terminal
ES1-24p-1 SEFOS(config)# lla
ES1-24p-1 SEFOS(config-lla)# role primary
ES1-24p-1 SEFOS(config-lla)# isl port-channel 100
ES1-24p-1 SEFOS(config-lla)# lla port-channel 101
ES1-24p-1 SEFOS(config-lla)# exit
ES1-24p-1 SEFOS(config)# end

Enable the configured LLA and port-channels.

Note - These settings take effect after saving the configuration and resetting SEFOS.

ES1-24p-1 SEFOS# configure terminal
ES1-24p-1 SEFOS(config)# set port-channel enable
ES1-24p-1 SEFOS(config)# set lla enable
ES1-24p-1 SEFOS(config)# end

Change the spanning-tree mode to PVRST and configure the bridge priority such that ToR72p-1 is root for all internal VLANs.

ES1-24p-1 SEFOS# configure terminal
ES1-24p-1 SEFOS(config)# spanning-tree mode pvrst
Spanning Tree enabled protocol is MSTP, now MSTP is being shutdown PVRST is started.
 PVRST Module status is changed

ES1-24p-1 SEFOS(config)# spanning-tree vlan 1 brg-priority 40960
ES1-24p-1 SEFOS(config)# end

Modify the spanning-tree cost on all VLANs for port-channels configured in the switch.

With this setting, the spanning-tree makes port-channel 100 a designated port connecting ES1-24p-1 and ES1-24p-2. This port is in the forwarding state.
