It is typically used to transmit data packets from one host to multiple hosts. To allow routers to distribute multicasts out one of its ports, they use a protocol called Internet Group Management Protocol (IGMP). Hosts send an IGMP join message to get a multicast stream. When a router receives an IGMP join message at one of its interfaces, it knows there are hosts … text/html 2020-10-24T05:52:59+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.3av.us/doku.php?id=cisco:switch:configure_intervlan_routing_on_layer_3_switches&rev=1603518779&do=diff CONFIGURE INTERVLAN ROUTING ON LAYER 3 SWITCHES Introduction This document provides the configuration and troubleshooting steps applicable to the creation of Layer 3 interfaces. VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing. On Catalyst switches it is accomplished by the creation of Layer 3 interfaces (switch virtual interfaces (SVIs) ). text/html 2020-10-26T04:16:19+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.3av.us/doku.php?id=cisco:switch:configure_port_to_vlan_interface_settings_on_a_switch_through_the_cli&rev=1603685779&do=diff CONFIGURE PORT TO VLAN INTERFACE SETTINGS ON A SWITCH THROUGH THE CLI Objective A Virtual Local Area Network (VLAN) allows you to logically segment a Local Area Network (LAN) into different broadcast domains. In scenarios where sensitive data may be broadcast on a network, VLANs can be created to enhance security by designating a broadcast to a specific VLAN. Only users that belong to a VLAN are able to access and manipulate the data on that VLAN. text/html 2020-11-10T05:36:38+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.3av.us/doku.php?id=cisco:switch:configuring_network_security_with_acls&rev=1604986598&do=diff CONFIGURING NETWORK SECURITY WITH ACLS This chapter describes how to configure network security on the Catalyst 2960 and 2960-S switches by using access control lists (ACLs), also referred to as access lists.
