Command | Purpose |
Force10# configure |
Enter configuration mode. |
Force10(conf)# protocol spanning-tree rstp |
Enter RSTP configuration mode. |
Force10(conf-rstp)# bridge-priority 4096 (primary peer) Force10(conf-rstp)# bridge-priority 8192 (secondary peer) |
Optional: Configure RSTP bridge priority.*These priorities are not unique to the VLT pair and are used to show preference for the primary. Use a higher multiple of 4096 to avoid the primary becoming the root bridge. |
Force10(conf-rstp)# no disable |
Enable the spanning tree protocol. |
Command | Purpose |
Force10# configure |
Enter configuration mode. |
Force10(conf)# interface range fortyGigE 0/56 , fortyGigE 0/60 |
Enter interface configuration mode. Be aware of the spaces needed before and after the comma. |
Force10(conf-if-range-fo-0/56,fo-0/60)# no shutdown |
Enable the range of interfaces. |
Force10(conf-if-range-fo-0/56,fo-0/60)# interface port-channel 100 |
Enter port channel configuration mode. |
Force10(conf-if-po-100)# channel-member fortyGigE 0/56,60 |
Add the physical interface to the port channel. |
Force10(conf-if-po-100)# no shutdown |
Enable the port channel. |
Command | Purpose |
Force10# configure |
Enter configuration mode. |
Force10(conf)# vlt domain 1 |
Enter VLT domain configuration mode for domain ID 1-1000. |
Force10(conf-vlt-domain)# primary-priority 10 (primary peer) Force10(conf-vlt-domain)# primary-priority 20 (secondary peer) |
Optional: Specify the VLT priority for each peer switch. 1-65535 (highest to lowest) |
Force10(conf-vlt-domain)# back-up destination 1.1.1.2 (primary peer) Force10(conf-vlt-domain)# back-up destination 1.1.1.1 (secondary peer) |
Specify the management IP address of the peer switch. This sets up the Heartbeat that monitors the peer system status. |
Force10(conf-vlt-domain)# peer-link port-channel 100 |
Associate the VLTi LAG to the VLT domain. |
Force10(conf-vlt-domain)# system-mac <mac-address>Also, configure the same MAC address on the VLT peer switch. This command is used to minimize the time required for the VLT system to synchronize the default MAC address of the VLT domain on both peer switches when one peer switch reboots.
Command | Purpose |
Force10# configure |
Enter configuration mode |
Force10(conf)# interface tengigabit 0/20 |
Enter interface configuration mode |
Force10(conf-if-te-0/20)# port-channel-protocol lacp |
Enter LACP configuration mode |
Force10(conf-if-te-0/20-lacp)# port-channel 20 mode active |
Set the port channel as "mode active" for LACP LAG |
Force10(conf-if-te-0/20-lacp)# interface port-channel 20 |
Enter port channel configuration mode |
Force10(conf-if-po-20)# portmode hybrid |
Portmode hybrid allows the interface to pass tagged and untagged traffic. |
Force10(conf-if-po-20)# switchport |
Switchport puts the interface in layer 2 mode. |
Force10(conf-if-po-20)# vlt-peer-lag port-channel 20 |
Assign the port channel as a VLT port channel |
Force10(conf-if-po-20)#end |
Exit configuration mode |
Force10# write |
Save configuration |
