Return Materials Authorization. The Cisco program for returning faulty hardware and obtaining a
RMA
replacement.
Read-Only-Memory Monitor. ROMMON lets you TFTP system images onto the sensor for recovery
ROMMON
purposes.
See RTT.
round-trip time
remote-procedure call. Technological foundation of client/server computing. RPCs are procedure calls
RPC
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
RSM
like a standalone router.
Real-Time Transport Protocol. Commonly used with IP networks. RTP is designed to provide
RTP
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
RTT
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
Switch Configuration Protocol. Cisco control protocol that runs directly over the Ethernet.
SCP
Simple Certificate Enrollment Protocol. The Cisco Systems PKI communication protocol that
SCEP
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
SDEE
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.
SDEE Server
Protocol that provides a secure remote connection to a router through a Transmission Control Protocol
Secure Shell
(TCP) application.
Protocol
You can partition a single adaptive security appliance into multiple virtual devices, known as security
security context
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
Security Monitor
network devices. Used with the IDS MC.
