27 Virtual Link Trunking (VLT) Virtual link trunking (VLT) allows physical links between two chassis to appear as a single virtual link to the network core. VLT domain configuration is automatic and you must connect the base module ports for VLT interconnect (VLTi) communication. In VLT mode, port 0/9 is added in the LAG 127 and the LAG 127 is used as VLTi. If you change to VLT mode, reboot the I/O aggregator. VLT mode VLT provides Layer 2 multipathing, creating redundancy through increased bandwidth, enabling multiple parallel paths between nodes and load-balancing traffic where alternative paths exist. To enable VLT in FN2210S, convert the ports 9 and 10 to ethernet mode of operation. The VLT commands described in this chapter are: • show vlt backup-link • show vlt brief • show vlt detail • show vlt role • show vlt statistics • stack-unit iom-mode vlt show vlt backup-link Displays information on the backup link operation. Syntax Default show vlt backup-link Not configured. Command Modes Command History EXEC Version 9.4(0.0) Supported on the FN I/O aggregator.
