CatOS下定义VLAN

Step 1 Before you can create a VLAN, the switch must be in VTP server mode or VTP transparent mode. If the switch is a VTP server, you must define a VTP domain name before you can add any VLANs. This has to be defined regardless of the number of switches in the network (one or many), or whether or not you will be using VTP to propagate VLANs to other switches in the network. For details on VTP, please refer to the Understanding and Configuring VLAN Trunk Protocol (VTP) document.
　　
　　The default VTP configuration on the switch is as follows:
　　
　　
　　CatosSwitch> (enable) show vtp domain
　　Domain Name Domain Index VTP Version Local Mode Password
　　-------------------------------- ------------ ----------- ----------- ----------
　　1 2 server -
　　
　　Vlan-count Max-vlan-storage Config Revision Notifications
　　---------- ---------------- --------------- -------------
　　5 1023 0 disabled
　　
　　Last Updater V2 Mode Pruning PruneEligible on Vlans
　　--------------- -------- -------- -------------------------
　　0.0.0.0 disabled disabled 2-1000
　　
　　
　　Use the set vtp command to set the domain name and mode.
　　
　　
　　CatosSwitch> (enable) set vtp domain ?
　　 Domain name
　　CatosSwitch> (enable) set vtp domain cisco ?
　　mode Set VTP mode
　　passwd Set VTP password
　　pruning Set VTP pruning
　　v2 Set VTP version 2
　　
　　CatosSwitch> (enable) set vtp domain cisco mode ?
　　client VTP client mode
　　server VTP server mode
　　transparent VTP transparent mode
　　CatosSwitch> (enable) set vtp domain cisco mode server
　　VTP domain cisco modified
　　
　　Step 2 Verify VTP configuration by using the show vtp domain command.
　　
　　
　　CatosSwitch> (enable) show vtp domain
　　Domain Name Domain Index VTP Version Local Mode Password
　　-------------------------------- ------------ ----------- ----------- ----------
　　cisco 1 2 server -
　　
　　Vlan-count Max-vlan-storage Config Revision Notifications
　　---------- ---------------- --------------- -------------
　　5 1023 1 disabled
　　
　　Last Updater V2 Mode Pruning PruneEligible on Vlans
　　--------------- -------- -------- -------------------------
　　0.0.0.0 disabled disabled 2-1000
　　
　　If you have the output of a show vtp domain command from your Cisco device, you can use Output Interpreter to display potential issues and fixes. To use Output Interpreter , you must be a registered user, be logged in, and have JavaScript enabled.
　　
　　Step 3 Once the VTP domain has been set and verified, you can begin to create VLANs on the switch. By default, there is only a single VLAN for all ports, and this VLAN is called the default. VLAN1 cannot be renamed or deleted.
　　
　　You can use the show vlan command to display the parameters for all configured VLANs in the administrative domain, as shown below:
　　
　　
　　CatosSwitch> (enable) show vlan
　　VLAN Name Status IfIndex Mod/Ports, Vlans
　　---- -------------------------------- --------- ------- ------------------------

　　3/1-48

　　To create VLANs, use the set vlan command, as show below:
　　
　　
　　CatosSwitch> (enable) set vlan
　　Usage: set vlan
　　(An example of mod/port is 1/1,2/1-12,3/1-2,4/1-12)
　　set vlan [name ] [type ] [state ]
　　[pvlan-type ]
　　[said ] [mtu ] [ring ]
　　[decring ]
　　[bridge ] [parent ]
　　[mode ] [stp ]
　　[translation ] [backupcrf ]
　　[aremaxhop ] [stemaxhop ]
　　[rspan]
　　(name = 1..32 characters, state = (active, suspend)
　　type = (ethernet, fddi, fddinet, trcrf, trbrf)
　　said = 1..4294967294, mtu = 576..18190
　　pvlan-type = (primary,isolated,community,none)
　　hex_ring_number = 0x1..0xfff, decimal_ring_number = 1..4095
　　bridge_number = 0x1..0xf, parent = 2..1005, mode = (srt, srb)
　　stp = (ieee, IBM, auto), translation = 1..1005
　　hopcount = 1..13)
　　Set vlan commands:
　　----------------------------------------------------------------------------
　　set vlan Set vlan information
　　set vlan mapping Map an 802.1q vlan to an Ethernet vlan
　　
　　
　　CatosSwitch> (enable) set vlan 2 name cisco_vlan_2
　　Vlan 2 configuration successful
　　
　　Note: You can verify the VLAN configuration by using the show vlan command, as shown below:
　　
　　
　　CatosSwitch> (enable) show vlan
　　VLAN Name Status IfIndex Mod/Ports, Vlans
