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.
Context Rules
•
A maximum of 63 contexts may be configured per chassis.Enabling demux functions on an MIO card
reduces the maximum number of contexts to 10.
•
Interfaces per Context
◦
Prior to Release 15.0: Up to 16 interfaces can be configured within a single context.
◦
For Release 15.0 and higher: With the Demux MIO/UMIO/MIO2 feature enabled, up to 64
interfaces can be configured within a single context.
