Connecting a VLT Domain

To connect a VLT domain to an attached access device, use the following commands.

For more information, refer to Verifying a VLT Configuration.
  1. Configure the VLT domain with the same ID in VLT peer 1 and VLT peer 2. VLT DOMAIN vlt domain domain id
  2. Configure the VLTi between VLT peer 1 and VLT peer 2. LACP/Static LAG can be configured between the peer units (not shown). CONFIGURATION mode interface port-channel port-channel id
    • NOTE: To benefit from the protocol negotiations, Dell Networking recommends configuring VLTs used as facing hosts/switches with LACP. Both peers must use the same port channel ID.
  3. Configure the peer-link port-channel in the VLT domains of each peer unit. INTERFACE PORTCHANNEL mode channel-member
  4. Configure the backup link between the VLT peer units. Configure the peer 2 management ip/ interface ip for which connectivity is present in VLT peer 1. EXEC Privilege mode show running-config vlt
  5. Configure the peer 1 management ip/ interface ip for which connectivity is present in VLT peer 1. EXEC mode or EXEC Privilege mode show interfaces interface
  6. Configure the VLT links between VLT peer 1 and VLT peer 2 to the top of rack unit. Configure the static LAG/LACP between ports connected from VLT peer 1 and VLT peer 2 to the top of rack unit. EXEC Privilege mode show running-config entity
  7. Configure the VLT peer link port channel id in VLT peer 1 and VLT peer 2. EXEC mode or EXEC Privilege mode show interfaces interface
  8. In the top of rack unit, configure LACP in the physical ports. EXEC Privilege mode show running-config entity
  9. Verify VLT is running. EXEC mode show vlt brief show vlt detail
  10. Verify the VLT LAG is running in both VLT peer units. EXEC mode or EXEC Privilege show interfaces interface
In the following sample VLT configuration steps, VLT peer 1 is FN IOM-2, VLT peer 2 is FN IOM-4, and the ToR is FN IOM-1.
  • NOTE: If you use a third-party ToR unit, Dell Networking recommends using static LAGs with VLT peers to avoid potential problems if the VLT peers are rebooted.

Configure the VLT domain with the same ID in VLT peer 1 and VLT peer 2

fniom-2(conf)#vlt domain 5
                                 fniom-2(conf-vlt-domain)#
                                 
                                 fniom-4(conf)#vlt domain 5
                                 fniom-4(conf-vlt-domain)#
                              

Configure the VLTi between VLT peer 1 and VLT peer 2

  1. LACP/Static LAG can be configured between the peer units (not shown).
  2. Configure the peer-link port-channel in the VLT domains of each peer unit.
fniom-2(conf)#interface port-channel 1
                                 fniom-2(conf-if-po-1)#channel-member TenGigabitEthernet 0/4-7
                                 
                                 fniom-2(conf)#no shutdown
                                 fniom-4(conf)#interface port-channel 1
                                 fniom-4(conf-if-po-1)#channel-member TenGigabitEthernet 0/4-7
                                 fniom-4(conf)#no shutdown
                              

Configure the backup link between the VLT peer units

  1. Configure the peer 2 management ip/ interface ip for which connectivity is present in VLT peer 1.
  2. Configure the peer 1 management ip/ interface ip for which connectivity is present in VLT peer 2.

Configure the VLT links between VLT peer 1 and VLT peer 2 to the top of rack unit

In the following example, port Te 0/40 in VLT peer 1 is connected to Te 0/48 of TOR and port Te 0/18 in VLT peer 2 is connected to Te 0/50 of TOR.

  1. Configure the static LAG/LACP between ports connected from VLT peer 1 and VLT peer 2 to the top of rack unit.
  2. Configure the VLT peer link port channel id in VLT peer 1 and VLT peer 2.
  3. In the top of rack unit, configure LACP in the physical ports (shown for VLT peer 1 only. Repeat steps for VLT peer 2. The highlighted vlt-peer-lag port-channel 2 indicates that port-channel 2 is the port-channel id configured in VLT peer 2).
