VSB Interconnect Link Configuration

In a VSB enabled system, 40GbE port interconnections provide distribution between chassis. VSB supports either 2 (7100G-Series) or 4 (7100K-Series) 40GbE interconnection links between chassis It is recommended that you consider optimization of interconnect redundancy and optimization of bandwidth when determining the number and location of VSB interconnect links configured between bonded chassis.

Configure the VSB chassis using the set bonding chassis command (see VSB Chassis Configuration for details) before enabling VSB 40GbE interconnect ports.

Use the set bonding port enable command, specifying the 40GbE interconnect port, to enable the VSB interconnect port. The VSB interconnect port must be enabled on all chassis in the VSB stacking system. Port designation is based upon the standard physical chassis slot and port designation until VSB is globally enabled for the VSB system (See Globally Enabling and Disabling the VSB System). A minimum of one VSB interconnect link must be configured between bonded chassis before globally enabling VSB for the intended system to bond. Once VSB is globally enabled, VSB interconnect links can be added or modified.

See VSB Chassis Configuration for details concerning chassis slot numbering before and after a VSB system is globally enabled.

In a VSB system of x chassis that is globally enabled:

• Chassis 1 ports are specified as fg.1.x where x is the port number
• Chassis 2 ports are specified as fg.2.x where x is the port number
• Chassis x ports are specified as fg.x.y where x is the chassis number and y is the port number

When modifying interconnect ports in a globally enabled VSB system, use the globally enabled port designation to specify ports.
