VLANs in the VTP Database Chapter 8 Configuring VLANs Monitoring VTP You monitor VTP by displaying its configuration information: the domain name, the current VTP revision, and the number of VLANs. You can also display statistics about the advertisements sent and received by the switch. Beginning in privileged EXEC mode, follow these steps to monitor VTP activity: Step 1 Step 2 Command show vtp status show vtp counters Purpose Display the VTP switch configuration information. Display counters about VTP messages being sent and received. VLANs in the VTP Database You can set these parameters when you add a new VLAN to or modify an existing VLAN in the VTP database: • VLAN ID • VLAN name • VLAN type (Ethernet, Fiber Distributed Data Interface [FDDI], FDDI network entity title [NET], TRBRF or TRCRF, Token Ring, Token Ring-Net) • VLAN state (active or suspended) • Maximum transmission unit (MTU) for the VLAN • Security Association Identifier (SAID) • Bridge identification number for TRBRF VLANs • Ring number for FDDI and TRCRF VLANs • Parent VLAN number for TRCRF VLANs • STP type for TRCRF VLANs • VLAN number to use when translating from one VLAN type to another The "Default VLAN Configuration" section on page 8-21 lists the default values and possible ranges for each VLAN media type. Token Ring VLANs Although the Catalyst 2900 XL and Catalyst 3500 XL switches do not support Token Ring connections, a remote device such as a Catalyst 5000 series switch with Token Ring connections could be managed from one of the supported switches. Switches running this release advertise information about these Token Ring VLANs when running VTP version 2: • Token Ring TRBRF VLANs • Token Ring TRCRF VLANs For more information on configuring Token Ring VLANs, refer to the Catalyst 5000 Series Software Configuration Guide. 8-20 Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide 78-6511-08
