Table 119 describes the significant fields shown in the display.

Table 119 show vtp counters Field Descriptions 

Field
Description

Summary advertisements received

Number of summary advertisements received by this switch on its trunk ports. Summary advertisements contain the management domain name, the configuration revision number, the update time stamp and identity, the authentication checksum, and the number of subset advertisements to follow.

Subset advertisements received

Number of subset advertisements received by this switch on its trunk ports. Subset advertisements contain all the information for one or more VLANs.

Request advertisements received

Number of advertisement requests received by this switch on its trunk ports. Advertisement requests normally request information on all VLANs. They can also request information on a subset of VLANs.

Summary advertisements transmitted

Number of summary advertisements sent by this switch on its trunk ports. Summary advertisements contain the management domain name, the configuration revision number, the update timestamp and identity, the authentication checksum, and the number of subset advertisements to follow.

Subset advertisements transmitted

Number of subset advertisements sent by this switch on its trunk ports. Subset advertisements contain all the information for one or more VLANs.

Request advertisements transmitted

Number of advertisement requests sent by this switch on its trunk ports. Advertisement requests normally request information on all VLANs. They can also request information on a subset of VLANs.

Number of config revision errors

Number of revision errors.

Whenever you define a new VLAN, delete an existing VLAN, suspend or resume an existing VLAN, or modify the parameters on an existing VLAN, the configuration revision number of the switch increments.

Revision errors increment whenever the switch receives an advertisement whose revision number matches the revision number of the switch, but the MD5 digest values do not match. This error indicates that the VTP password in the two switches is different, or the switches have different configurations.

These errors indicate that the switch is filtering incoming advertisements, which causes the VTP database to become unsynchronized across the network.

Number of config digest errors

Number of MD5 digest errors.

Digest errors increment whenever the MD5 digest in the summary packet and the MD5 digest of the received advertisement calculated by the switch do not match. This error usually indicates that the VTP password in the two switches is different. To solve this problem, make sure the VTP password on all switches is the same.

These errors indicate that the switch is filtering incoming advertisements, which causes the VTP database to become unsynchronized across the network.

Number of V1 summary errors

Number of version 1 errors.

Version 1 summary errors increment whenever a switch in VTP V2 mode receives a VTP version 1 frame. These errors indicate that at least one neighboring switch is either running VTP version 1 or VTP version 2 with V2-mode disabled. To solve this problem, change the configuration of the switches in VTP V2-mode to disabled.

Join Transmitted

Number of VTP pruning messages transmitted on the trunk.

Join Received

Number of VTP pruning messages received on the trunk.

Summary Advts Received from non-pruning-capable device

Number of VTP summary messages received on the trunk from devices that do not support pruning.

Table 120 show vtp status Field Descriptions 

Field
Description

VTP Version

Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers

Displays the VTP version operating on the switch. By default, switches implement version 1.

Catalyst Switches

Displays the VTP version operating on the switch. By default, Catalyst 2900 and 3500 XL switches implement version 1 but can be set to version 2.

Configuration Revision

Current configuration revision number on this switch.

Maximum VLANs Supported Locally

Maximum number of VLANs supported locally.

Number of Existing VLANs

Number of existing VLANs.

VTP Operating Mode

Displays the VTP operating mode, which can be server, client, or transparent.

Server—A switch in VTP server mode is enabled for VTP and sends advertisements. You can configure VLANs on it. The switch guarantees that it can recover all VLAN information in the current VTP database from nonvolatile storage after reboot. By default, every switch is a VTP server.

Client—A switch in VTP client mode is enabled for VTP, can send advertisements, but does not have enough nonvolatile storage to store VLAN configurations. You cannot configure VLANs on it. When a VTP client starts up, it does not transmit VTP advertisements until it receives advertisements to initialize its VLAN database.

Transparent—A switch in VTP transparent mode is disabled for VTP, does not transmit advertisements or learn from advertisements sent by other devices, and cannot affect VLAN configurations on other devices in the network. The switch receives VTP advertisements and forwards them on all trunk ports except the one on which the advertisement was received. The configuration of multi-VLAN ports causes the switch to automatically enter transparent mode.

Note Catalyst 2912MF, 2924M, and 3500 XL switches support up to 250 VLANs. All other Catalyst 2900 XL switches support up to 64 VLANs. If you define more than 250 or 64 or if the switch receives an advertisement that contains more than 250 or 64 VLANs, the switch automatically enters VTP transparent mode and operates with the VLAN configuration preceding the one that sent it into transparent mode.

Note Catalyst 2912MF, 2924M, and 3500 XL switches support up to 250 VLANs. All other Catalyst 2900 XL switches support up to 64 VLANs.

For Catalyst 2912MF, 2924M, and 3500 XL switches, if you define more than 250 or if the switch receives an advertisement that contains more than 250 VLANs, the switch automatically enters VTP transparent mode and operates with the VLAN configuration preceding the one that sent it into transparent mode.

For all other Catalyst 2900 XL switches, if you define more than 64 or if the switch receives an advertisement that contains more than 64 VLANs, the switch automatically enters VTP transparent mode and operates with the VLAN configuration preceding the one that sent it into transparent mode.

VTP Domain Name

Name that identifies the administrative domain for the switch.

VTP Pruning Mode

Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers

VTP pruning mode is not supported on the Cisco 2600 series and Cisco 3600 series routers.

Catalyst Switches

Displays whether pruning is enabled or disabled. Enabling pruning on a VTP server enables pruning for the entire management domain. Pruning restricts flooded traffic to those trunk links that the traffic must use to access the appropriate network devices.

VTP V2 Mode

Displays if VTP version 2 mode is enabled. All VTP version 2 switches operate in version 1 mode by default. Each VTP switch automatically detects the capabilities of all other VTP devices. A network of VTP devices should be configured to version 2 only if all VTP switches in the network can operate in version 2 mode.

VTP Traps Generation

Displays whether VTP traps are transmitted to a network management station.

MD5 Digest

16-byte checksum of the VTP configuration.

Configuration Last Modified

Displays the date and time of the last configuration modification. Displays the IP address of the switch that caused the configuration change to the database.

Usage Guidelines

The columns marked VCD, VPI, and VCI display information for the corresponding private VC on the control interface. The private VC connects the XTagATM VC to the external switch. It is termed private because its VPI and VCI are only used for communication between the MPLS LSC and the switch, and it is different from the VPI and VCI seen on the XTagATM interface and the corresponding switch port.

Examples

Each connection is listed twice in the sample output from the show xtagatm vc cross-connect command under each interface that is linked by the connection. Connections are marked as input (unidirectional traffic flow, into the interface), output (unidirectional traffic flow, away from the interface), or in/out (bidirectional).

The following is sample output from the show xtagatm vc command:

Router# show xtagatm vc

snmp-server enable traps mpls ldp

To enable the sending of Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) Simple Network Management Protocol (SNMP) notifications, use the snmp-server enable traps mpls ldp command in global configuration mode. To disable the sending of MPLS LDP notifications, use the no form of this command.

snmp-server enable traps mpls ldp [session-up | session-down | pv-limit | threshold]

no snmp-server enable traps mpls ldp [session-up | session-down | pv-limit | threshold]

Syntax Description

session-up

(Optional) Controls (enables or disables) LDP session up notifications, defined in the MPLS-LDP-MIB as mplsLdpSessionUp. This notification is generated when the router establishes an LDP session with another LDP entity (an adjacent LDP peer in the network).

session-down

(Optional) Controls (enables or disables) LDP session down notifications, defined in the MPLS-LDP-MIB as mplsLdpSessionDown. This message is generated when an LDP session between the router and its adjacent LDP peer is terminated.

pv-limit

(Optional) Controls (enables or disables) Path-Vector (PV) Limit notifications, defined in the MPLS-LDP-MIB as mplsLdpPVLMismatch. This notification is generated when the router establishes an LDP session with its adjacent peer label switch router (LSR), but the two LSRs have dissimilar path vector limits.

threshold

(Optional) Controls (enables or disables) PV Limit notifications, defined in the MPLS-LDP-MIB as mplsLdpInitSesThresholdExceeded. This notification is generated after eight failed attempts to establish an LDP session between the router and an LDP peer, due to any type of incompatibility between the devices.


Defaults

The sending of SNMP notifications is disabled by default.

If you do not specify any of the optional keywords, all four types of LDP notifications are enabled on the LSR.

12.0(21)ST

12.2(13)T

This command was integrated into Cisco IOS Release 12.2(13)T.


Usage Guidelines

The MPLS LDP pv-limit (mplsLdpPathVectorLimitMismatch) notification object provides a warning message that can be sent to the NMS when two routers engaged in LDP operations have a dissimilar path vector limit. It is recommended that all LDP-enabled routers in the network be configured with the same path vector limit.

The value of the path vector limit can range from 0 through 255; a value of 0 indicates that loop detection is off; any value other than zero up to 255 indicates that loop detection is on and, in addition, specifies the maximum number of hops through which an LDP message can pass before a loop condition in the network is sensed.

The MPLS LDP threshold (mplsLdpFailedInitSessionThresholdExceeded) notification object provides a warning message that can be sent to a network management station (NMS) when a local LSR and an adjacent LDP peer attempt to set up an LDP session between them, but fail to do so after a specified number of attempts. The default number of attempts is 8. This default value is implemented in Cisco IOS and cannot be changed using either the CLI or an SNMP agent.

In general, Cisco routers support the same features across multiple platforms. Therefore, the most likely incompatibility to occur between Cisco LSRs is a mismatch of their respective ATM VPI/VCI label ranges.

For example, if you specify a range of valid labels for an LSR that does not overlap the range of its adjacent LDP peer, the routers will try eight times to create an LDP session between themselves before the mplsLdpFailedInitSessionThresholdExceeded notification is generated.

Operationally, the LSRs whose label ranges do not overlap continue their attempt to create an LDP session between themselves after the eight retry threshold is exceeded. In such cases, the LDP threshold exceeded notification alerts the network administrator to the existence of a condition in the network that may warrant attention.

RFC 3036, LDP Specification, details the incompatibilities that can exist between Cisco routers and/or other vendor LSRs in an MPLS network. Among such incompatibilities, for example, are the following:

Non-overlapping ATM VPI/VCI ranges (as noted above) or non-overlapping Frame-Relay DLCI ranges between LSRs attempting to set up an LDP session

Unsupported label distribution method

Dissimilar protocol data unit (PDU) size

Dissimilar LDP feature support

The snmp-server enable traps mpls ldp command is used in conjunction with the snmp-server host command. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. To send SNMP notifications, you must configure at least one snmp-server host command.

Examples

The following example shows how to enable LDP-specific informs that will be sent to the host myhost.cisco.com using the community string defined as public:

Router(config)# snmp-server enable traps mpls ldp
Router(config)# snmp-server host myhost.cisco.com informs version 2c public mpls-ldp

snmp-server enable traps mpls traffic-eng

To enable Multiprotocol Label Switching (MPLS) traffic engineering tunnel state-change Simple Network Management Protocol (SNMP) notifications, use the snmp-server enable traps mpls traffic-eng command in global configuration mode. To disable MPLS traffic engineering tunnel state-change SNMP notifications, use the no form of this command.

snmp-server enable traps mpls traffic-eng [up | down | reroute]

no snmp-server enable traps mpls traffic-eng [up | down | reroute]

Syntax Description

up

(Optional) Enables only mplsTunnelUp notifications { mplsTeNotifyPrefix 1 }. MplsTunnelUp notifications are sent to a network management system (NMS) when an MPLS traffic engineering tunnel is configured and the tunnel transitions from an operationally "down" state to an "up" state.

down

(Optional) Enables only mplsTunnelDown notifications { mplsTeNotifyPrefix 2 }. MplsTunnelDown notifications are generated and sent to the NMS when an MPLS traffic engineering tunnel transitions from an operationally "up" state to a "down" state.

reroute

(Optional) Controls (enables or disables) only mplsTunnelRerouted notifications { mplsTeNotifyPrefix 3 }. MplsTunnelRerouted notifications are sent to the NMS under the following conditions:

1) The signaling path of an existing MPLS traffic engineering tunnel fails for some reason and a new path option is signaled and placed into effect (that is, the tunnel is rerouted).

or

2) The signaling path of an existing MPLS traffic engineering tunnel is fully operational, but a better path option can be signaled and placed into effect (that is, the tunnel can be reoptimized). This reoptimization can be triggered by: a) a timer, b) the issuance of an mpls traffic-eng reoptimize command, or c) a configuration change that requires the resignalling of a tunnel.


Defaults

SNMP notifications are disabled by default.

If this command is used without keywords, all available trap types (up, down, reroute) are enabled.

This command was integrated into Cisco IOS Release 12.2(8)T


Usage Guidelines

SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform requests.

This command controls (enables or disables) MPLS traffic engineering tunnel notifications. MPLS Tunnel StateChange notifications, when enabled, will be sent when the connection moves from an "up" to "down" state, when a connection moves from a "down" to "up" state, or when a connection is rerouted.

If you do not specify a specific argument in conjunction with this command, all three types of MPLS traffic engineering tunnel notifications will be sent.

The snmp-server enable traps mpls traffic-eng command is used in conjunction with the snmp-server host command. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. To send SNMP notifications, you must configure at least one snmp-server host command.

Examples

The following example shows how to enable the router to send MPLS notifications to the host at the address myhost.cisco.com using the community string defined as public:

snmp-server enable traps mpls vpn

To enable the router to send Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) specific Simple Network Management Protocol (SNMP) notifications (traps and informs), use the snmp-server enable traps mpls vpn command in global configuration mode. To disable MPLS VPN specific SNMP notifications, use the no form of this command.

snmp-server enable traps mpls vpn [vrf-up] [vrf-down] [mid-threshold] [max-threshold] [illegal-label]

no snmp-server enable traps mpls vpn [vrf-up] [vrf-down] [mid-threshold] [max-threshold] [illegal-label]

Syntax Description

vrf-up

(Optional) Enables a notification for the assignment of a VPN routing/forwarding instance (VRF) to an interface that is operational or for the transition of a VRF interface to the operationally up state.

vrf-down

(Optional) Enables a notification for the removal of a VRF from an interface or the transition of an interface to the down state.

mid-threshold

(Optional) Enables a notification of a warning that the number of routes created has crossed the warning threshold. This warning is sent only at the time the warning threshold is exceeded. The warning threshold value is a percentage of the max-threshold value, and is set using the maximum routes limit warn-threshold VRF configuration mode command.

max-threshold

(Optional) Enables a notification that the maximum route limit (maximum route threshold) has been reached. Another notification is sent when the number of routes falls below the maximum route limit value. The max-threshold value is determined by the maximum routes VRF configuration mode command.

illegal-label

(Optional) Enables a notification for any illegal labels received on a VRF interface. Labels are illegal if they are outside the legal range, do not have a Label Forwarding Information Base (LFIB) entry, or do not match table IDs for the label.

This command was integrated into Cisco IOS Release 12.2(13)T.


Usage Guidelines

If this command is used without any of the optional keywords, all MPLS VPN notification types are enabled.

For the vrf-up (mplsVrfIfUp) or vrf-down (mplsVrfIfDown) notifications to be issued from an ATM or Frame Relay subinterface, you must first configure the snmp-server traps atm subif command or the snmp-server traps frame-relay subif command on the subinterfaces, respectively.

The values for mid-threshold and max-threshold are set using the maximum routes limit warn-threshold [warn-only] VRF configuration mode command.


Note The warn-only keyword in the maximum routes command sets the value of the MaxThresholdobject to an effectively infinite number, so MaxThreshExceeded (max-threshold) SNMP notifications will never be sent for the configured VRF if the maximum routes limit warn-only command is used. In other words, the maximum routes limit warn-only command will generate syslog messages when the limit value (max-threshold) is reached, but SNMP notifications will not be generated.


The notification types described above are defined in the following MIB objects of the PPVPN-MPLS-VPN-MIB as follows:

mplsVrfIfUp

mplsVrfIfDown

mplsNumVrfRouteMidThreshExceeded

mplsNumVrfRouteMaxThreshExceeded

mplsNumVrfSecIllegalLabelThreshExceeded

Examples

The following example shows how to send MPLS VPN trap notifications to the host specified as 172.31.156.34 using the community string named public if a VRF transitions from a down state to an up state or from an up state to a down state:

This command was integrated into Cisco IOS Release 12.2(8)T on the Cisco 2600 series, Cisco 3600 series, and Cisco 3700 series routers.


Usage Guidelines

When setting the max-age seconds, if a bridge does not hear Bridge Protocol Data Units (BPDU) from the root bridge within the specified interval, it assumes that the network has changed and recomputes the spanning tree topology.

Valid values for protocol are dec (Digital STP), ibm (IBM STP), ieee (IEEE Ethernet STP), and vlan-bridge (VLAN Bridge STP).

The spanning-tree root primary command alters this switch's bridge priority to 8,192. If you enter after spanning-tree root primary command and the switch does not become root, then the bridge priority is changed to 100 less than the bridge priority of the current bridge. If the switch does not become root, an error results.

The spanning-tree root secondary command alters this switch's bridge priority to 16,384. If the root switch should fail, this switch becomes the next root switch.

Use the spanning-tree root commands on backbone switches only.

Examples

The command is only available on interfaces that can serve as a VSI master control port. We recommend that all options to the tag-control-protocol vsi command be entered at the same time.

After VSI is active on the control interface (through the earlier issuance of a tag-control-protocol vsi command), reentering the command may cause all associated XTagATM interfaces to shut down and restart. In particular, if you reenter the tag-control-protocol vsi command with any of the following options, the VSI shuts down and reactivates on the control interface:

id

base-vc

slaves

VSI remains continuously active (that is, the VSI does not shut down and then reactivate) if you reenter the tag-control-protocol vsi command with only one or both of the following options:

keepalive

retry

delay

In either case, if you reenter the tag-control-protocol vsi command, this causes the specified options to take on the newly specified values; the other options retain their previous values. To restore default values to all the options, enter the no tag-control-protocol command, followed by the tag-control-protocol vsi command.

Examples

The following example shows how to configure the VSI driver on the control interface:

Router(config)# interface atm 0/0
Router(config-if)# tag-control-protocol vsi base-vc 0 51
