CISCO switch 2950 has several unusual features to improve network performance, manageability, and security. Network administrators can configure up to 64 virtual VLAN VLANs for each vswitch) to achieve higher data security and enhanced LAN performance. This ensur

◆ After The VTP password is set, The VTP transparent mode is SW5) No VTP notification is forwarded.
◆ In Version1 VTP without a password, a switch in transparent mode does not forward the received VTP notification to check the domain name and version number)
◆ In Version2 VTP without a password, the vswitch domain name in transparent mode may be different from the vtp server.) The forwarded VTP notification does not check the domain name

When more than one VLAN is divided on the three-layer switch, and each VLAN uses the IP address of different network segment, to realize all the computers under the switch
I have just been familiar with the basic configurations of the VLAN division experiment of the switch VLAN division configuration (PT simulator). I am not familiar with this knowledge for too long. Please forgive me for any errors, this configuration is for you to learn about the Cisco simulator configuration case. Www

Add Catalyst 5002 to the domain
You need to add Catalyst 5002 To The VTP management domain named cisco and set it to VTP client. It will receive VTP configurations and updates from the VTP server.
Note: by default, the Catalyst 5000 series switches are VTP servers.
