Glossary RMA ROMMON round-trip time RPC RSM RTP RTT RU Return Materials Authorization. The Cisco program for returning faulty hardware and obtaining a replacement. Read-Only-Memory Monitor. ROMMON lets you TFTP system images onto the sensor for recovery purposes. See RTT. remote-procedure call. Technological foundation of client/server computing. RPCs are procedure calls that are built or specified by clients and are executed on servers, with the results returned over the network to the clients. Router Switch Module. A router module that is installed in a Catalyst 5000 switch. It functions exactly like a standalone router. Real-Time Transport Protocol. Commonly used with IP networks. RTP is designed to provide end-to-end network transport functions for applications transmitting real-time data, such as audio, video, or simulation data, over multicast or unicast network services. RTP provides such services as payload type identification, sequence numbering, timestamping, and delivery monitoring to real-time applications. round-trip time. A measure of the time delay imposed by a network on a host from the sending of a packet until acknowledgement of the receipt. rack unit. A rack is measured in rack units. An RU is equal to 44 mm or 1.75 inches. S SCP SCEP SDEE SDEE Server Secure Shell Protocol security context Security Monitor Switch Configuration Protocol. Cisco control protocol that runs directly over the Ethernet. Simple Certificate Enrollment Protocol. The Cisco Systems PKI communication protocol that leverages existing technology by using PKCS#7 and PKCS#10. SCEP is the evolution of the enrollment protocol. Security Device Event Exchange. A product-independent standard for communicating security device events. It adds extensibility features that are needed for communicating events generated by various types of security devices. Accepts requests for events from remote clients. Protocol that provides a secure remote connection to a router through a Transmission Control Protocol (TCP) application. You can partition a single adaptive security appliance into multiple virtual devices, known as security contexts. Each context is an independent device, with its own security policy, interfaces, and administrators. Multiple contexts are similar to having multiple standalone devices. Many features are supported in multiple context mode, including routing tables, firewall features, IPS, and management. Monitoring Center for Security. Provides event collection, viewing, and reporting capability for network devices. Used with the IDS MC.
