Command History
Version 9.0(1.3) Introduced on the S5000.
Usage
Information
When you create a VLT domain on a switch, FTOS automatically assigns a unique unit ID (0 or
1) to each peer switch. The unit IDs are used for internal system operations. Use the unit-id
command to explicitly configure the unit ID of a VLT peer. You must configure a different unit ID
(0 or 1) on each peer switch.
Use this command to minimize the time required for the VLT system to determine the unit ID
assigned to each peer switch when one peer reboots.
vlt domain
Use this command to enable VLT on a switch, configure a VLT domain, enter VLT-domain configuration mode, set a VLT
port delay time, set VLT priorities and configure a VLT peer link.
S5000
Syntax
vlt domain domain-id
Parameters
domain-id
Enter the Domain ID number. You must configure the same domain ID
on the peer switch. VLT uses the domain ID to automatically create a
VLT MAC address for the domain. The range of domain IDs is 1 to
1000.
