GLOSSARY
A
ACL
Access Control List. A mechanism in computer security used to enforce privilege separation. An ACL
identifies the privileges and access rights a user or client has to a particular object, such as a server, file
system, or application.
activate
Places an entity into the resource pool for load balancing content requests or connections and starts the
keepalive function. See also suspend.
administrative
distance
The first criterion a router uses to determine which routing protocol to use if two protocols provide
route information for the same destination. Administrative distance is a measure of the trustworthiness
of the source of the routing information. Administrative distance has only local significance, and is not
advertised in routing updates.
The smaller the administrative distance value, the more reliable the protocol. The values range from 0
(zero) for a connected interface and 1 for a static route, to 255 for an unknown protocol.
AES
Advanced Encryption Standard. One of the possible encryption algorithms available for use in SNMP
communications.
ARP
Address Resolution Protocol. Internet protocol used to map an IP address to a MAC address. Defined
in RFC 826.
B
BVI
Bridge-Group Virtual Interface. Logical Layer 3-only interface associated with a bridge group when
integrated routing and bridging (IRB) is configured.
C
CCM
Cisco CallManager. A Cisco product that provides the software-based, call-processing component of
the Cisco IP Telephony Solutions for the Enterprise, part of Cisco AVVID (Architecture for Voice,
Video, and Integrated Data). CallManager acts as a signaling proxy for call events initiated over other
common protocols such as SIP, ISDN (Integrated Services Digital Network), or MGCP (Media
Gateway Control Protocol).
