Overview

ESA objects in the NFM-P navigation tree

When the NFM-P discovers applicable 7750 SR chassis, Release 20.5 R1 and later, the ESAs group object appears automatically in the navigation tree. The ESA operates as a resource server that provides packet buffering and processing, and is connected to the 7750 SR using standard SR interface ports.

The ESAs group objects are children of 7750 SR device objects. They appear above logical group objects in the navigation tree. ESA objects are children of ESAs group objects, and as such appear below the ESAs group object in the navigation tree. The ESA hosts up to four Virtual Machine (VM) instances for multiservice processing. VM objects are created in the navigation tree as children of the ESA object.

See the NSP NFM-P Network Element Compatibility Guide for information about which SR devices support ESAs.

Working with ESA objects

An ESA hosts up to four VM instances for multiservice processing.

An ESA VM may use up to four host ports. Each physical port can be used to bring up each VM within an ESA. With four host ports, four VMs can be operationally up. ESA VMs can be different types or the same type.

ESA VMs are configured as a desired type and size (number of cores and amount of memory).

Multiple ESAs may be configured per IOM and per system as needed for scale. See the node documentation for more information.
