serverUse the vmps server global configuration command to configure the primary VLAN MembershipPolicy Server (VMPS) and up to three secondary servers.Use the no form of this command to removea VMPS server.vmps server ipaddress [primary]no vmps server [ipaddress]Syntax Description ipaddress IP address or host name of the primary or secondary VMPS servers.If you specifya host name, the Domain Name System (DNS) server must be configured.primary (Optional) Determines whether primary or secondary VMPS servers are beingconfigured.Defaults No primary or secondary VMPS servers are defined.Command Modes Global configurationCommand History Release Modification11.2(8)SA4 This command was first introduced.Usage Guidelines The first server entered is automatically selected as the primary server whether or not primary isentered.The first server address can be overridden by using primary in a subsequent command.If a member switch in a cluster configuration does not have an IP address, the cluster does not use theVMPS server configured for that member switch.Instead, the cluster uses the VMPS server on thecommand switch, and the command switch proxies the VMPS requests.The VMPS server treats thecluster as a single switch and uses the IP address of the command switch to respond to requests.When using the no form without specifying the ipaddress, all configured servers are deleted.If youdelete all servers when dynamic-access ports are present, the switch cannot forward packets from newsources on these ports because it cannot query the VMPS.Catalyst 2900 Series XL and Catalyst 3500

return to the default setting.vtp {server | client | transparent}no vtp {server | client | transparent}Syntax Description server Place the switch in VTP server mode.A switch in VTP server mode is enabledfor VTP and sends advertisements.You can configure VLANs on it.The switchcan recover all the VLAN information in the VTP database from nonvolatilestorage after reboot.client Place the switch in VTP client mode.A switch in VTP client mode is enabled forVTP, can send advertisements, but does not have enough nonvolatile storage tostore VLAN configurations.You cannot configure VLANs on it.When a VTPclient starts up, it does not transmit VTP advertisements until it receivesadvertisements to initialize its VLAN database.transparent Place the switch in VTP transparent mode.A switch in VTP transparent mode isdisabled for VTP, does not transmit advertisements or learn from advertisementssent by other devices, and cannot affect VLAN configurations on other devicesin the network.The switch receives VTP advertisements and forwards them onall trunk ports except the one on which the advertisement was received.Theconfiguration of multi-VLAN ports causes the switch to automatically entertransparent mode.Note The switch supports up to 250 VLANs on the Catalyst 2912MF, 2924M, and Catalyst 3500 XL switches.All other Catalyst 2900 XL switches support up to 64 VLANs [ Pobierz całość
