Tags: color-o switch test one-arm routing access via interface implementation representationTo achieve inter-VLAN communication, in addition to configuring the SVI interface on the switch, you can also implement VLAN data forwarding by configuring sub-interfaces under the physical interface of the router.Configuration ideas:1 The access switch configures the corresponding VLAN and sets the access PC port to access mode2 Setting the physical interface of the router to which the switch is connecte
Nat[network address translation] In the absence of IP address in the case of a great use, it can not be normal Sisu network of the intranet address into a legitimate external network address on the public network to send and receive data. At the same time address translation function can also be very good to hide and protect the host network.Nat has static NAT (internal address and external address one-to-one) and dynamic NAT (internal address pool and external address Pool A-do)This time we'll
Network address port Conversion NAPT is a very familiar way of transformation. NAPT is commonly used in access devices, which can hide small and medium-sized networks behind a legitimate IP address.Unlike dynamic address NAT, NAPT maps An internal connection to a separate IP address in the external network, adding a TCP port number selected by the NAT device to the address.This time, let's get to know napt.Configuration ideas1 Configure the router's interface IP address, note the network segment
RIP protocols can be configured in a more convenient way, but the limitations of RIP itself indicate that it is not suitable for medium to large networks. In contrast, OSPF is more complex to configure than RIP, but its functionality and performance are better than RIP.Configuration ideas1 Configure the physical interface address of the router Xia Lian switch and the physical interface address of the router to the other router and open the port2 Configure the address of the switch Xia Lian PC an
Through the previous experiment we learned that by configuring VLANs, the terminals under different VLANs could not communicate with each other, but if you wanted to communicate between different VLANs, you would need to configure inter-VLAN routingLayer three switches have the capability of the network layer and can be forwarded via the routing functionNetwork environment1 set the IP address and gateway of the terminal (192.168.1.1 and 192.168.2.1, respectively).2 VLAN is configured under Layer

Before creating a user name, you need to log on to the database as a user Administrator 1, to create a table space before creating a user:
The format is: Format: Create tablespace table name datafile ' data file name ' size table space;
For example:
sql> Create tablespace mytable datafile ' d:\myoracle\mytables1.dbf ' size 1024M segment space management auto;
If the table space is insufficient to import data, you can modify the table space as follows:
Sql>alter database datafile ' d:\myoracle\my

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 connected to the switch, The VLAN allocation a
