Cisco A9K-ISM-100= Network Switch Module Networking

Cisco® ASR 9000 Series Integrated Service Module (ISM) is a universal service foundation for Cisco ASR 9000 Aggregation Services Routers. The module provides a highly scalable modular services delivery platform for delivering multiple types of services. Currently the Integrated Services Module (Figure 1) supports the following services:
● Carrier Grade Network Address Translation (NAT): CGN
● Dual-Stack Lite
● Stateful NAT64
● Mapping of Address and Port Translation (MAP-T)
The service hosted on an ISM may be changed at any time by changing the service image loaded on the ISM. Multiple services can coexist on multiple ISMs in the same Cisco ASR 9000 system.
