Virtual Link Trunking (VLT) | 927
Use the delay-restore command at any time to set an amount of time, in seconds, to delay the system from
restoring the VLT port. Refer to VLT Port Delayed Restoration for more information.

2 Enter an amount of time, in seconds, to delay the

2 (Optional) After you configure the VLT domain on each
peer switch on both sides of the interconnect trunk, by
default, the FTOS software elects a primary and
secondary VLT peer device.
Use the primary-priority command to reconfigure the
primary role of VLT peer switches. To configure the
primary role on a VLT peer, enter a lower value than the
priority value of the remote peer.
Priority values are from 1 to 65535. Default: 32768.

CONFIGURATION
3 (Optional) When you create a VLT domain on a switch,
the FTOS software automatically creates a VLT-system
MAC address used for internal system operations.
Use the system-mac command to explicitly configure
the default MAC address for the domain by entering a
new MAC address in the format: aaaa.bbbb.cccc.
You must also reconfigure the same MAC address on
the VLT peer switch.
Use this command 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.
