Examples of CPE types include modems, routers, gateways, set-top boxes, and VoIP-phones. TR-069 was first published in May 2004, with amendments in 2006, 2007, 2010, July 2011 (version 1.3), [ 1 ] and November 2013 (version 1.4 am5) [ 2 ] The Home Gateway Initiative (HGI), Digital Video Broadcasting Project (DVB) and WiMAX Forum have endorsed CWMP.
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.
With a VLAN Management Policy Server (VMPS), an administrator can assign switch ports to VLANs dynamically based on information such as the source MAC address of the device connected to the port or the username used to log onto that device. As a device enters the network, the switch queries a database for the VLAN membership of the port that ...
QinQ allows multiple VLAN tags to be inserted into a single frame, an essential capability for implementing metro Ethernet. In a multiple-VLAN-header context, out of convenience, the term VLAN tag or just tag for short is often used in place of 802.1Q VLAN header. QinQ allows multiple VLAN tags in an Ethernet frame; together these tags ...
Some devices with dual-band wireless network connectivity do not allow the user to select the 2.4 GHz or 5 GHz band (or even a particular radio or SSID) when using Wi-Fi Protected Setup, unless the wireless access point has separate WPS button for each band or radio; however, a number of later wireless routers with multiple frequency bands and ...
As traffic passes from the network to the Internet, NAT translates the source address in each packet from a private address to the router's public address. The router tracks basic data about each active connection (particularly the destination address and port). When the router receives inbound traffic from the Internet, it uses the connection ...
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.
A Private VLAN divides a VLAN (Primary) into sub-VLANs (Secondary) while keeping existing IP subnet and layer 3 configuration. A regular VLAN is a single broadcast domain, while private VLAN partitions one broadcast domain into multiple smaller broadcast subdomains. Primary VLAN: Simply the original VLAN. This type of VLAN is used to forward ...
