VLT DOMAIN CONFIGURATION modeprimary-priority valueThe priority values are from 1 to 65535. The default is 32768.If the primary peer fails, the secondary peer (with the higher priority) takes the primary role. If the primary peer (with the lowerpriority) later comes back online, it is assigned the secondary role (there is no preemption).6 (Optional) Prevent a possible loop during the bootup of a VLT peer switch or a device that accesses the VLT domain.CONFIGURATION modelacp ungroup member-independent {vlt | port-channel port-channel-id}LACP on VLT ports (on a VLT switch or access device), which are members of the virtual link trunk, is not brought up until the VLTdomain is recognized on the access device.7 Repeat Steps 1 to 5 on the VLT peer switch to configure the IP address of this switch as the endpoint of the VLT backup link and toconfigure the same port channel for the VLT interconnect.Configuring a VLT Backup LinkTo configure a VLT backup link, use the following command.1 Specify the management interface to be used for the backup link through an out-of-band management network.CONFIGURATION modeinterface managementethernet slot/portEnter the slot (0-1) and the port (0).2 Configure an IPv4 address (A.B.C.D) or IPv6 address (X:X:X:X::X) and mask (/x) on the interface.MANAGEMENT INTERFACE mode{ip address ipv4-address/ mask | ipv6 address ipv6-address/ mask}This is the IP address to be configured on the VLT peer with the back-up destination command.3 Ensure that the interface is active.MANAGEMENT INTERFACE modeno shutdown4 Configure a VLT backup link using the IPv4 or IPv6 address of the VLT peer’s management interface.MANAGEMENT INTERFACE modeback-up destination {ip address ipv4-address/ mask | ipv6 address ipv6-address/ mask}5 Repeat Steps 1 to 4 on the VLT peer switch.To set an amount of time, in seconds, to delay the system from restoring the VLT port, use the delay-restore command at any time.For more information, refer to VLT Port Delayed Restoration.Configuring a VLT Port Delay PeriodTo configure a VLT port delay period, use the following commands.1 Enter VLT-domain configuration mode for a specified VLT domain.998 Virtual Link Trunking (VLT)
