cisco sip trunk configuration

The core switch is still quite common, So I studied the TRUNK configuration function of the core switch. Here I will share it with you and hope it will be useful to you. What is TRUNK? What application advantages can TRUNK bring to us? How to configure the TRUNK in a specifi

vswitch. The method to increase the bandwidth is effective when the connection between a single switch and a node cannot meet the load. The main function of TRUNK is to bind multiple physical ports to a logical channel, which works like a channel. After multiple physical links are bound together, not only the bandwidth of the entire network is increased, but the data can also be The transmission of multiple bound physical links has the function of li

Role of the switch serial port (Trunk: The following two encapsulation types can be used for relay over Ethernet through the serial port of the switch: -IEEE 802.1Q -ISL (Inter Switch Link, Cisco private) Procedure Step 1: Add a VLAN to the vswitch Switch1 # vlan database Switch1 (vlan) # vlan 2 Switch1 (vlan) # vlan 3 Switch1 (vlan) # exit Step 2: add the interface to the corresponding VLAN Swital # conf

A 4506 switch is connected through the trunk port and 3550, and then 6 switches are connected through the trunk at 3550!The specific configuration is as follows:4506:Trunk, encapsulation dot1q on int gi4/1Vtp domain ciscoVtp mode server divides 10 VLANs3550:Six trunk ports a

that the admin domain is able to overwrite all branch switches. The Cisco switch is capable of supporting any media as a trunk, and it can use its own ISL tags for relaying. ISL (Inter-Switch link) is a protocol between switches, between switches and routers, and between switches and servers to transfer multiple VLAN information and VLAN data streams, configured with ISL encapsulation via ports directly c

The hybrid port and trunk ports can be added to multiple VLANs, enabling interoperability of the VLAN on the switch with

For example:Switch # show vlan 3 2. configuration of multiple switchesTo allow a VLAN to span multiple switches, you must configure the trunk (trunk) to connect to these switches.
