Licensing (S-Series)

VSB entitlement is by chassis. If one module in the chassis is entitled to VSB, the chassis is VSB entitled. VSB is supported by default on the S155 and S180 module, and any module that has a VSB hardware interconnect port present. A license is required when globally enabling VSB on chassis containing only S130 and S150 modules. When a VSB enabled S155 module is hot swapped with an S130 or S150 module or a license expires, VSB is not disabled on the new or license expired module. If no other module in the chassis is entitled to VSB, an error message will display every five minutes until a valid license is configured on the module.

The displayed error message will be similar to:

System[2]Virtual Switch Bonding (VSB) is enabled on chassis-2 without a valid license. This message will continue until the license is configured or VSB is disabled.
System[1]Virtual Switch Bonding (VSB) is enabled on chassis-1 without a valid license. This message will continue until the license is configured or VSB is disabled.

A feature entitlement verification check occurs when attempting to enable VSB globally. If only modules not entitled to VSB are installed in the system, you must activate a VSB license on each chassis in the system before attempting to globally enable VSB.

Use the set license vsb command, specifying the license key and VSB chassis ID, to configure the module with a valid license. The show license command displays license status per chassis, before the VSB system is globally enabled, or for both chassis once the VSB system is globally enabled.
