Virtual Link Trunking (VLT) | 1025
To verify the configuration of a VLT domain, enter any of the show commands described in Verifying a
VLT Configuration.
For a sample configuration, see the following steps.

16
Configure the LACP port channel mode.

Repeat steps 1 through 15 for the VLT peer node in Domain 1.
19
Repeat steps 1 through 15 for the first VLT node in Domain 2.
20
Repeat steps 1 through 15 for the VLT peer node in Domain 2.

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

Configure the VLTi between VLT peer 1 and VLT peer 2.
1. LACP/Static LAG can be config-
ured between the peer units (not
shown).

CONFIGURATION
Note: To benefit from the protocol negotiations, Dell Force10 recommends VLTs used as facing hosts/switches are
configured with LACP. Both peers should use the same port channel ID.
2. Configure the peer-link port-chan-
nel in the VLT domains of each
peer unit.

INTERFACE PORTCHANNEL
Configure the backup link between the VLT peer units.
1. Configure the peer 2 management
ip/ interface ip for which connec-
tivity is present in VLT peer 1.

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