SRC Configuration and Management Tools
The SRC software provides the following configuration and management tools for the SRC module:
The SRC CLI is the software interface that you use to configure, monitor, and manage a C Series Controller and SRC software, including the SRC module. The SRC CLI uses the same operational model as the Junos OS CLI, which you use to configure and monitor routers running Junos OS.
The CLI provides numerous commands and statements and organizes them in a hierarchical fashion. Commands that perform a similar function are grouped together under the same level of the hierarchy. You type commands on a single line, and the commands are executed when you press the Enter key. The CLI provides command help and command completion, and supports Emacs-style keyboard sequences that allow you to move around on a command line and scroll through recently executed commands.
The C-Web interface is an application that allows you to configure, monitor, and manage a C Series Controller and SRC software by means of a Web browser through Hypertext Transfer Protocol (HTTP) or HTTP over Secure Sockets Layer (HTTPS). The C-Web interface uses the same operational model as the J-Web interface, which you use to configure and monitor routers running Junos OS.
The C-Web interface supports the configuration, monitoring, and management tasks that you can perform with the SRC CLI. Figure 3 shows a C-Web configuration page for the SAE.
Policy and Management
The SRC software works with Juniper Networks routers and PacketCable Multimedia Specification (PCMM) compliant CMTS platforms to provide differentiated QoS. SRC policies define how the router or the CMTS device treats subscriber traffic. Policy management is responsible for defining policies and deploying the policies in an SRC network.
For routers running Junos OS, the SRC software supports class-of-service (CoS), firewall filters, policing, stateful firewall, stateless firewall, and Network Address Translation (NAT) services.
For routers running JunosE Software, the SRC software supports policy routing, rate limiting, QoS classification and marking, packet forwarding, and packet filtering.
The Policies, Services, and Subscribers CLI and the Policies, Services, and Subscriptions subtasks in the C-Web interface allow easy specification and validation of policies. The policies are stored in the Juniper Networks database. It works closely with a policy engine, which performs dynamic policy decisions while activating services, leveraging on the directory content to decide which policies to use in a given context.
SRC SNMP Agent
The SRC SNMP agent monitors system performance and availability, system resources, and SRC processes that are running on the system. The agent obtains information from traps through SNMP. The SRC SNMP agent is preconfigured to monitor SRC processes. Additionally, it provides detailed monitoring and configuration of SRC server components such the SAE, NIC hosts, and the policy engine.
The master agent determines the SNMP version that supports integration with other network management systems. The SRC SNMP agent runs as a subagent to an installed master agent using the Agent Extensibility (AgentX) protocol. The SRC SNMP agent cannot act as a master agent.
