CLI Session Rules
Multiple CLI session support is based on the amount of available memory. The internal Resource Manager reserves enough resources to support a minimum of six CLI sessions at all times. One of the six sessions is further reserved for use exclusively by a CLI session on the serial interface.
Additional CLI sessions beyond the pre-reserved limit are permitted if sufficient resources are available. If the Resource Manager is unable to reserve resources for a CLI session beyond those that are pre-reserved, users with administrator-privileges are prompted to create the new CLI session, even without reserved resources.
