Virtual LAN. A group of devices on one or more LANs that are configured (using management

Voice over IP. VoIP carries normal voice traffic, such as telephone calls and faxes, over an IP-based
VoIP
network. DSP segments the voice signal into frames, which then are coupled in groups of two and
stored in voice packets. These voice packets are transported using IP in compliance with ITU-T
specification H.323.

VPNs between clients, such as PCs, or a headend, such as the FWSM.

Virtual Router Redundancy Protocol. VRRP is an election protocol that dynamically assigns
VRRP
responsibility for one or more virtual router(s) to the VRRP router(s) on a LAN, allowing several
routers on a multiaccess link to utilize the same virtual IP address.

This lets different vendors have VSAs of the same number. The combination of a vendor number and
a VSA number makes a VSA unique. For example, the cisco-av-pair VSA is attribute 1 in the set of
VSAs related to vendor number 9. Each vendor can define up to 256 VSAs. A

subattributes.
