Command VTP Transparent Use This is the legacy way to configure VTP transparent mode. VTP transparent mode allows the switch to modify its VLAN database, but will not propagate changes from a server. Additionally, VTP transparent mode allows the switch to configure extended range VLANS (1006-4094). Syntax Switch(vlan)#vtp …
Command VTP Pruning Use This is the legacy way of configuring VTP pruning. VTP pruning spares bandwidth and adds to security by paying attention to what switches have interfaces assigned to VLANs. If a switch isn’t using a particular VLAN, the VTP server will block traffic from the …
Command Exit Use This command exits the VLAN database and applies any changes. Leaving the VLAN database by any other method will discard any changes. Syntax Switch(vlan)#exit Example In the below example we will enter the VLAN database, configure VLAN 99 and exit without using the exit command. Looking at show …
Command Apply Use This command applies any changes to the VLAN database but doesn’t exit the VLAN database. In fact, the exit command is a macro that runs the applycommand before exiting. Syntax Swtich(vlan)#apply Example In the below example we will enter the VLAN database, configure VLAN 99 and exit without …
Command VTP Client Use This is the legacy way to configure VTP client mode. VTP client mode doesn’t allow to create any VLANs. All VLANs must be learned from a server switch. This prevents the switch from accidently propogating VLANs throughout the network. The other use for this …
Command VTP Domain Use This is the legacy command for setting up a VTP domain name and enabling VTP on a network. If you have full communication between your VTP network, you only need to use this command on the VTP server because other switches will automatically learn …
Command Vlan Use This is the legacy way to configure VLANs on a switch. While this mode is being depreciated, you will still encounter it on older switches or routers with switch modules. On newer IOS releases, VLANs are configured in configure mode. Syntax Switch(vlan)#vlan <number> OR Switch(vlan)#vlan …
Command Configure Terminal Use To enter global configuration mode, use the configure terminal command in privileged EXEC mode. Syntax Switch#configure terminal Example In this example, the user switches to global configuration mode by entering in the configure terminal command. Switch# configure terminal Switch(config)#
Command Vlan Database Use This command enters the VLAN database on a switch. This is the legacy way to configure VLAN and VTP information on switches. On newer IOS releases, VLANs and VTP are configured in configure mode. Syntax Switch#vlan database Example In the below example we will …
Command Clear IP EIGRP Neighbors Use Clears the EIGRP adjacencies on the router. Syntax Router#clear ip eigrp neighbors Example In this example the EIGRP adjacencies are cleared on R1. Here are the adjacencies on R1 before clearing. R1#show ip eigrp neighbors IP-EIGRP neighbors for process 100 H Address Interface Hold …
