Using VMPS Client and VTP Pruning on Catalyst 5000 Series Route Switch Modules
This chapter describes the configuration procedures for the VMPS Client application for the Catalyst 5000 series switch Route Switch Module (RSM).
To start the VMPS Client application from CiscoView, select Configure>device>VMPS Client.
Where windows display optional fields, you can enter a value, or you can leave the field blank so that the device automatically generates the value.
For additional information on fields in the windows, click Help to access the online help.
When you select the VMPS Client category, the VMPS Client window allows you to configure the Catalyst 5000 series switch as a VMPS client.
The following action buttons are available:
- Reconfirm---To cause the switch to contact the VMPS immediately to reconfirm the current VLAN assignments for all dynamic ports on the switch, click Reconfirm.
- Add...---To specify the VMPS address type, click Add.... Select the VMPS address and click Add.... Select the VMPS type and click Apply to set configuration.
- Primary---To specify the VMPS address as primary, select the VMPS address and click Primary. Click Yes in the confirmation window.
Note The primary type will be used first, if it is reachable. Otherwise one of the "other" entries will be used. Setting one entry to primary causes any previous primary entry to change to "other."
If you select the VMPS Server category, the VMPS Server window allows you to change the administrative status of the device as a VMPS server (active or inactive) or download VMPS server information.
The following action buttons are available:
- Modify---To activate or deactivate this device as a VMPS server, select the administrative status (as appropriate), and click Modify.
Note When set to active, the VMPS will attempt to download the configuration file from the server.
- Download---To download the configuration file from the server, enter the IP address of the host supplying the TFTP configuration data for the VMPS in the Configuration Server's IP field. Enter the filename of the configuration file the VMPS will attempt to download in the Configuration File Name field, and click Download. (See "Hints for Modifying the VMPS Server Configuration" for more information.)
When setting the Configuration Server's IP address field, if the value of this object is set to 0.0.0.0, the VMPS will not attempt to download configuration information.
When you select the VMPS Server MAC-to-VLAN category, the VMPS Server MAC-to-VLAN window opens to display all VMPS MAC configuration information.
Note This feature is available only when the device is active on the VMPS server.
If you select the VTP Pruning category, the VTP Pruning window opens to allow you to modify VTP configuration for a specific VLAN. To modify the current configuration, edit the field(s) and click Modify to commit the modification. If an invalid value is entered, an error message is displayed. (See "Hints for Modifying VTP Pruning VLANs" for more information.)
When defining the fields, consider the following:
- When setting the Trunk Encapsulation Type field, setting the VLAN encapsulation type is both device and interface specific.
- When setting the Pruning Eligible VLAN's field, the value is entered as an octet string containing one bit per VLAN in the management domain on this trunk port. The first octet corresponds to VLANs with VlanIndex values of 0 through 7; the second octet to VLANs 8 through 15, and so forth. The most significant bit of each octet corresponds to the lowest value VlanIndex in that octet. If the bit corresponding to a VLAN is set to `1,' then the local system is permitted to prune that VLAN on this trunk port; if the bit is set to `0,' then the system must not prune that VLAN on this trunk port. To avoid conflicts between overlapping partial updates by multiple managers, for example, updates which modify only a portion of an instance of this object, such as enabling/disabling a single VLAN on the trunk port, any SNMP Set operation accessing an instance of this object should also write the value of vlanTrunkPortSetSerialNo.
- When setting the Allowed VLAN's field, the value is entered as an octet string containing one bit per VLAN in the management domain on this trunk port. The first octet corresponds to VLANs with VlanIndex values of 0 through 7; the second octet to VLANs 8 through 15, and so forth. The most significant bit of each octet corresponds to the lowest value VlanIndex in that octet. If the bit corresponding to a VLAN is set to `1,' then the local system is enabled for sending and receiving frames on that VLAN; if the bit is set to `0,' then the system is disabled from sending and receiving frames on that VLAN. To avoid conflicts between overlapping partial updates by multiple managers, for example, updates which modify only a portion of an instance of this object, such as enabling/disabling a single VLAN on the trunk port, any SNMP Set operation accessing an instance of this object should also write the value of vlanTrunkPortSetSerialNo.
- When setting the Pruning Requested VLAN's field, the value is entered as an octet string containing one bit per VLAN in the management domain on this trunk port. The first octet corresponds to VLANs with VlanIndex values of 0 through 7; the second octet to VLANs 8 through 15, and so forth. The most significant bit of each octet corresponds to the lowest value VlanIndex in that octet. If the bit corresponding to a VLAN is set to `1,' then this VLAN is presently being forwarded on this trunk port, for example, it is not pruned; if the bit is set to `0,' then this VLAN is presently not being forwarded on this trunk port, either because it is pruned or for some other reason.
- When setting the Active VLAN's field, the value is entered as an octet string containing one bit per VLAN in the management domain on this trunk port. The first octet corresponds to VLANs with VlanIndex values of 0 through 7; the second octet to VLANs 8 through 15, and so forth. The most significant bit of each octet corresponds to the lowest value VlanIndex in that octet. If the bit corresponding to a VLAN is set to `1,' then the local switch is currently sending joins for this VLAN on this trunk port, for example, it is asking to receive frames for this VLAN; if the bit is set to `0,' then the local switch is not currently sending joins for this VLAN on this trunk port.
The VLAN Router Table window displays RSM (Router Switch Module) information, including module number, IP address of the module, status, VLAN number, and the software version.
The RSM is a single card router supported by the Catalyst 5000 series switches. It is a one-armed router (indicating that it receives and transmits packets from the same physical interface) that connects to the backplane bus. The RSM replaces external routers but does not change the VLAN network architecture: one RSM replaces one external router.
