private vlan configuration example

Experiment topology:Objective: To: (1) Disable pc3 access without affecting hosts on other LAN(2) enable all hosts in the LAN to access the Internet. (Only one public address is available)(3) automatically obtain the Host IP address in the LAN.(4) r1 provides single-arm routing and dhcp functions to implement inter-vlan CommunicationIn accordance with the above requirements, to allow all hosts to access the Internet with only one public IP address, yo

An example of how to configure an ACL to ensure the VLAN security of a vswitch. I would like to introduce the VLAN security problem of a vswitch to you. Many people may not understand the VLAN security problem of the vswitch. It does not matter. After reading this article, you will surely have a lot of GAINS, I hope th

Note: The vlan number of a vswitch starts from VLAN 2 because the vswitch has a default VLAN, namely VLAN 1, which includes all users connected to the vswitch. The VLAN configuration process is actually very simple. Only two steps

between switches. It is an information packet marking protocol. Frames sent on ISL interfaces are composed of a standard Ethernet frame and related VLAN information. As shown in, data from different VLANs can be transmitted on interfaces that support ISL. Iii. Virtual LAN (VLAN) routing instance. Example 1:The device uses the ipvst5500 switch 1, the installation

option is to submit only the specified name list (you can use show Security acl ip name editbuffer to view control entries not submitted to the content in the editing buffer ), the all option is used to submit all unwritten vacls.3. Map to VLANBoth vacl and ACL must be mapped to the target object after submission, for example, interface vlan1 // ip access-group 101 out: apply access-list 101 to the out direction of the vlan1 interface. 101 indicates

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 configuration for linux Nic in virtual deployment (1) This article from Bkjia "Drop water stone Sun Jie" blog, original address: http://xjsunjie.blog.51cto.com/999372/1633815 If the switch port connected to the server has been configured with TRUNK in advance and allows specific VLANs to pass through, the server Nic must be configured with the corresponding

network router end, you need to configure the server end. Here, we mainly set IP addresses and routes. Note that if the port is tagged, the server's IP address must be configured with the corresponding vlan id. Here, we use the solaris server as an example. On solaris 10, the network port configuration is as follows: root @ solaris :~ # Ls-lah/etc/hostname. *-rw

, reducing network complexity and improving server management capabilities and large-scale scalability. Each UCS rack server is equipped with a VIF interface card that provides two Gigabit Ethernet interfaces. using Cisco Network virtualization technology, it provides both management network interfaces and operating system network interfaces. FI is the old version of 6120, which is inconsistent with the new server version. Therefore, you need to set all versions to the latest version, for

three-tier switch with routing function. Among them, the three layer switch is suitable for dividing the large and medium VLAN network, the router is suitable to divide the small VLAN network. Therefore, for the general Enterprise network environment, the router way to build VLAN network is the most practical solution. In layman's parlance, the establishment of

Here, I will share with you a small configuration instance. This is a configuration example that I want to understand for a long time. It's a long time for me to study independently.
