First of all, when configuring the switch, we should note that the IP address, gateway, domain name and other information set in the switch are set for use in managing the switch. After all these configurations are configured successfully, it can save a lot of trouble in the future work.
3350 configuration dhcp, there are many discussions on the network, but most of them have errors and omissions. After following the configuration of "IP HELPER-ADDRESS DHCP server address" introduced online, it was found that the client could not obtain the IP address from the DHCP server.
I have recently configured 3350 as the DHCP server relay agent. I was confused for a long time at the beginning. Later, I searched for information online and sought help from everyone on the forum. Finally, I passed the test in the project. In order to avoid everyone from touching the left and right in the project, I wrote down the configuration process for everyone as a reference.
Network environment: a 3550EMI switch, divided into three vlans, vlan2, which are the network where the server is located, named server, IP address segment is 192.168.2.0, subnet mask: 255.255.255.0, gateway: 192.168.2.1, and the domain server is Windows 2000 advance server.
It also serves as a DHCP server and a DNS server. The IP address is 192.168.2.10. vlan3 is the network where client 1 is located. The IP address segment is 192.168.3.0. Subnet mask: 255.255.255.0. Gateway: 192.168.3.1 is named work01. vlan4 is named work02. Named as work02. The IP address segment is 192.168.4.0. Subnet mask: 255.255.255.0. Gateway: 192.168.4.1.
Last time I introduced how to connect to the switch correctly. Today I will use some configuration fragments to introduce the port configuration to you. Given that most configuration examples on the Internet are the result of show-run. It is not conducive to novices' understanding of the command configuration process, so the author has noted the configuration fragments and attention, hoping to help novices understand how to correctly configure the switch as soon as possible.
When entering commands in IOS, as long as the abbreviation level does not cause confusion, you can use the abbreviation form when using configuration commands. For example: Switch>enable. In user mode, the command starting with en only enable, so it can be abbreviated as Switch>en. You can also use the TAB key to automatically complete the command, such as Switch>en, and then press the keyboard TAB to automatically complete the command to Switch>enable.
The port working modes of configuring the switch can generally be divided into three types: Access, Multi, and Trunk. The ports in trunk mode are used for switches and switches, switches and routers, and are mostly used for cascading network devices, so they are also called trunk mode. Access is mostly used in the access layer, also called the access mode. For the time being, we will introduce Trunk mode, Access mode, Multi mode, etc. First, when we introduce VLAN settings in the future.
The interface range can uniformly configure a set of ports. If the port is known to be directly connected to the PC and will not connect to the routing switch and hub, you can use the spanning-tree portfast command to set the fast port. The fast port no longer goes through the four states of the spanning tree, and directly enters the forwarding state to improve access speed.
