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.
On router platforms with software-only forwarding (e.g., Cisco 7200), most traffic handling, including access control list filtering and forwarding, is done at interrupt level using Cisco Express Forwarding (CEF) or dCEF (Distributed CEF).
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.
IOS XE is a release train of Cisco Systems' widely deployed Internetworking Operating System (IOS), introduced with the ASR 1000 series. [2]It is built on Linux [3] [4] and provides a distributed software architecture that moves many operating system responsibilities out of the IOS process [5] [6] and has a copy of IOS running as a separate process. [7]
Cisco routers running the Cisco IOS operating system can be configured using the command line interface: [11] > enable # configure terminal (config) # ip route 10 .10.20.0 255 .255.255.0 192 .168.100.1
IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
It is based on Wind River Linux and is inter-operable with other Cisco operating systems. [citation needed] The command-line interface of NX-OS is similar to that of Cisco IOS. [2] Recent NX-OS has both Cisco-style CLI and Bash shell available. On NX-OS 7.0(3)I3, the output from uname with the -a command line argument might look like the text ...
