Configuring VLANs
Objectives
pleting this lesson, you will be able to:
Use Cisco mands to configure VLANs, VTP, IEEE trunking, and ISL trunking, given a functioning access layer switch
Execute an add, move, or change on an access-layer switch, given a work requirement
Use mands to identify anomalies in VLAN, VTP, IEEE trunking, ISL trunking, and spanning-tree operation within a VLAN, given an operational access layer switch
Use mands to identify events and anomalies in VLAN, VTP, IEEE trunking, ISL trunking, and spanning-tree operation, given an operational access layer switch
VTP domain name
VTP mode (server/client/transparent)—VTP server mode is the default
VTP pruning
VTP password
VTP trap
Use caution when adding a new switch to an existing domain. Add a new switch in client mode to prevent the new switch from propagating incorrect VLAN information.
Use the delete mand to reset the VTP revision number.
VTP Configuration Guidelines
wg_sw_1900#configure terminal
Enter mands, one per line. End TL/Z
wg_sw_1900(config)#vtp transparent
wg_sw_1900(config)#vtp domain switchlab
wg_sw_1900(config)#vtp [server | transparent | client] [domain domain-name] [trap {enable | disable}] [password password] [pruning {enable | disable}]
Creating a VTP Domain
Catalyst 1900
Catalyst 2950
wg_sw_2950#vlan database
wg_sw_2950(vlan)#vtp [ server | client | transparent ]
wg_sw_2950(vlan)#vtp domain domain-name
wg_sw_2950(vlan)#vtp password password
wg_sw_2950(vlan)#vtp pruning
wg_sw_2950(vlan)#snmp-server enable traps vtp
wg_sw_2950(vlan)#exit
VTP Configuration Example
wg_sw_1900(config)#vtp transparent
wg_sw_1900(config)#vtp domain switchlab pruning enable
wg_sw_1900(config)#exit
wg_sw_1900#show vtp
VTP version: 1
Configuration revision: 4
Maximum VLANs supported locally: 1005
Number of existing VLANs: 6
