This protocol is used as part of Packet Tracer 7.2.2 capabilities to transmit data between Packet Tracer and Cisco's CSR routing platform. [ 12 ] [ 13 ] As of mid-2022, little is known about this protocol or its functionality.
This is known as inter-VLAN routing. On layer-3 switches it is accomplished by the creation of layer-3 interfaces (SVIs). Inter VLAN routing, in other words routing between VLANs, can be achieved using SVIs. [1] SVI or VLAN interface, is a virtual routed interface that connects a VLAN on the device to the Layer 3 router engine on the same device.
Ethernet devices must allow a minimum idle period between transmission of Ethernet packets. [1] A brief recovery time between packets allows devices to prepare for reception of the next packet. While some physical layer variants literally transmit nothing during the idle period, most modern ones continue to transmit an idle pattern signal.
Cisco Inter-Switch Link (ISL) is a Cisco proprietary link layer protocol that maintains VLAN information in Ethernet frames as traffic flows between switches and routers, or switches and switches. [1] ISL is Cisco's VLAN encapsulation protocol and is supported only on some Cisco equipment over the Fast and Gigabit Ethernet links. It is offered ...
This port communicates with P-Ports and ports on the same community VLAN. Example scenario: a switch with VLAN 100, converted into a Private VLAN with one P-Port, two I-Ports in Isolated VLAN 101 (Secondary) and two community VLANs 102 and 103 (Secondary), with 2 ports in each. The switch has one uplink port (trunk), connected to another switch.
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.
IP routing is the application of routing methodologies to IP networks. This involves not only protocols and technologies but includes the policies of the worldwide organization and configuration of Internet infrastructure.
The SP has two switches, one in Seattle (S-Switch #1), and one in Tacoma (S-Switch #2). The customers interface to the SP network in switches designated A and B. Each customer has its own pair of A and B switches. Acme switch A is connected to S-Switch #1 through link A1; the rest of the links are labeled. S-Switch #1 and #2 are connected by ...
