A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS, [1] they are used in several places, for example: To indicate the size of a network or subnet for some routing protocols, such as OSPF. To indicate what IP addresses should be permitted or denied in access control lists ...
A VLAN access control list (VACL) provides access control for all packets that are bridged within a VLAN or that are routed into or out of a VLAN. Unlike regular Cisco IOS access control lists that are configured on router interfaces and applied on routed packets only, VACLs apply to all packets.
In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1] Each entry in a typical ACL specifies a subject and an operation.
Note that in the diagram the incorrect label ESSID (Extended Service Set Identifier) refers to the service set identifier. In IEEE 802.11 wireless local area networking standards (including Wi‑Fi ), a service set is a group of wireless network devices which share a service set identifier ( SSID )—typically the natural language label that ...
A typical IP access controller supports 2 or 4 basic access control readers. IP access controllers may have an internal web server that is configurable using a browser or using software installed on a host PC. The main features that distinguish IP controllers from older generations of serial controllers are: IP controllers connect directly to ...
Packets that hold Internet Protocol data carry a 4-bit IP version number as the first field of its header. [ 1 ] [ 2 ] Currently, only IPv4 and IPv6 packets are seen on the Internet , having IP version numbers 4 and 6, respectively.
IP-CAN (or IP connectivity access network) is an access network that provides Internet Protocol (IP) connectivity. [1] The term is usually used in cellular context and usually refers to 3GPP access networks such as GPRS or EDGE , but can be also used to describe wireless LAN (WLAN) or DSL networks.
