privileged EXEC command, the
show sdm prefer
command shows the template currently in use and the template that will become active after a reload.
Use the
no sdm prefer
command to set the switch to the default template.
You must use a routing template on switches running the IP Services image for Layer 3 functionality.
Do not use the routing template if you are not using Layer 3 functionality on your switch. Entering the
sdm prefer routing
global configuration command prevents other features from using the memory allocated to unicast routing in the routing template.
Do not use the dual IPv4 and IPv6 template if you do not plan to enable IPv6 functionality on the switch. Entering the
sdm prefer ipv4-and-ipv6
global configuration command divides resources between IPv4 and IPv6, limiting those allocated to IPv4 forwarding.
Table 2-16

service password-recovery
Use the
service password-recovery
global configuration command to enable the password-recovery mechanism (the default). This mechanism allows an end user with physical access to the switch to hold down the
Express Setup
button and interrupt the bootup process while the switch is powering up and to assign a new password. Use the
no
form of this command to disable part of the password-recovery functionality. When the password-recovery mechanism is disabled, interrupting the bootup process is allowed only if the user agrees to set the system back to the default configuration.
service password-recovery
no service password-recovery
Syntax Description
This command has no arguments or keywords.
Defaults
The password-recovery mechanism is enabled.

This command was introduced.
|
Usage Guidelines
As a system administrator, you can use the
no service password-recovery
command to disable some of the functionality of the password recovery feature by allowing an end user to reset a password only by agreeing to return to the default configuration.
To use the password-recovery procedure, you must have physical access to the switch.
To delete the switch password and set a new one, follow these steps:
Step 1
Press the
Express Setup
button until the SETUP LED blinks green and the LED of an available switch downlink port blinks green.
If no switch downlink port is available for your PC or laptop connection, disconnect a device from one of the switch downlink ports. Press the
Express Setup
button again until the SETUP LED and the port LED blink green.
Step 2 Connect your PC or laptop to the port with the blinking green LED.
The SETUP LED and the switch downlink port LED stop blinking and stay solid green.
Step 3 Press and hold the
Express Setup
button. Notice that the SETUP LED starts blinking green again. Continue holding the button until the SETUP LED turns solid green (approximately 5 seconds). Release the
Express Setup
button immediately.
This procedure deletes the password without affecting any other configuration settings. You can now access the switch without a password through the console port or by using the device manager.
Step 4 Enter a new password through the device manager by using the Express Setup window or through the command line interface by using the
enable secret
global configuration command.
Note If you use the no service password-recovery command to control end user access to passwords, we recommend that you save a copy of the config file in a location away from the switch in case the end user uses the password recovery procedure and sets the system back to default values. Do not keep a backup copy of the config file on the switch.
If the switch is operating in VTP transparent mode, we recommend that you also save a copy of the vlan.dat file in a location away from the switch.
You can verify if password recovery is enabled or disabled by entering the
show version
privileged EXEC command.
Examples
This example shows how to disable password recovery on a switch so that a user can only reset a password by agreeing to return to the default configuration.
Switch(config)# no service-password recovery

|
A policy map can now be applied to a physical port or an SVI.
|
Usage Guidelines
Only one policy map per ingress port is supported.
Policy maps can be configured on physical ports or on SVIs. When VLAN-based quality of service (QoS) is disabled by using the
no mls qos vlan-based
interface configuration command on a physical port, you can configure a port-based policy map on the port. If VLAN-based QoS is enabled by using the
mls qos vlan-based
interface configuration command on a physical port, the switch removes the previously configured port-based policy map. After a hierarchical policy map is configured and applied on an SVI, the interface-level policy map takes effect on the interface.
You can apply a policy map to incoming traffic on a physical port or on an SVI. You can configure different interface-level policy maps for each class defined in the VLAN-level policy map. For more information about hierarchical policy maps, see the “Configuring QoS” chapter in the software configuration guide for this release.
Classification using a port trust state (for example,
mls qos trust
[
cos
|
dscp
|
ip-precedence
] and a policy map (for example,
service-policy input
policy-map-name
) are mutually exclusive. The last one configured overwrites the previous configuration.
Examples
This example shows how to apply
plcmap1
to an physical ingress port:
Switch(config)# interface gigabitethernet1/1 Switch(config-if)# service-policy input plcmap1
This example shows how to remove
plcmap2
from a physical port:
Switch(config)# interface gigabitethernet1/1 Switch(config-if)# no service-policy input plcmap2
This example shows how to apply
plcmap1
to an ingress SVI when VLAN-based QoS is enabled:
Switch(config)# interface vlan 10 Switch(config-if)# service-policy input plcmap1
This example shows how to create a hierarchical policy map and attach it to an SVI:
Switch(config)# access-list 101 permit ip any any Switch(config)# class-map cm-1 Switch(config-cmap)# match access 101 Switch(config-cmap)# exit Switch(config)# class-map cm-interface-1 Switch(config-cmap)# match input gigabitethernet1/1 - gigabitethernet1/2 Switch(config-cmap)# exit Switch(config)# policy-map port-plcmap Switch(config-pmap)# class-map cm-interface-1 Switch(config-pmap-c)# police 900000 9000 exc policed-dscp-transmit Switch(config-pmap-c)# exit Switch(config)# policy-map vlan-plcmap Switch(config-pmap)# class-map cm-1 Switch(config-pmap-c)# set dscp 7 Switch(config-pmap-c)# service-policy port-plcmap-1 Switch(config-pmap-c)# exit Switch(config-pmap)# class-map cm-2 Switch(config-pmap-c)# match ip dscp 2 Switch(config-pmap-c)# service-policy port-plcmap-1 Switch(config-pmap)# exit Switch(config-pmap)# class-map cm-3 Switch(config-pmap-c)# match ip dscp 3 Switch(config-pmap-c)# service-policy port-plcmap-2 Switch(config-pmap)# exit Switch(config-pmap)# class-map cm-4 Switch(config-pmap-c)# trust dscp Switch(config-pmap)# exit Switch(config)# interface vlan 10 Switch(config-if)# ser input vlan-plcmap

Usage Guidelines
If you have used the
set ip dscp p
olicy-map class configuration command, the switch changes this command to
set dscp
in the switch configuration. If you enter the
set ip dscp
policy-map class configuration command, this setting appears as
set dscp
in the switch configuration.
You can use the
set ip precedence
policy-map class configuration command or the
set precedence
policy-map class configuration command. This setting appears as
set ip precedence
in the switch configuration.
The set command is mutually exclusive with the trust policy-map class configuration command within the same policy map.
For the
set dscp
new-dscp
or the
set
ip precedence
new-precedence
command, you can enter a mnemonic name for a commonly used value. For example, you can enter the
set dscp af11
command, which is the same as entering the
set dscp 10
command. You can enter the
set ip precedence critical
command, which is the same as entering the
set ip precedence 5
command. For a list of supported mnemonics, enter the
set dscp ?
or the
set ip precedence ?
command to see the command-line help strings.
To return to policy-map configuration mode, use the
exit
command. To return to privileged EXEC mode, use the
end
command.
Examples
This example shows how to assign DSCP 10 to all FTP traffic without any policers:
Switch(config)# policy-map policy_ftp Switch(config-pmap)# class ftp_class Switch(config-pmap-c)# set dscp 10 Switch(config-pmap)# exit
You can verify your settings by entering the
show policy-map
privileged EXEC command.

Usage Guidelines
When Express Setup is enabled on a new (unconfigured) switch, pressing the Express Setup button for 2 seconds activates Express Setup. You can access the switch through an Ethernet port by using the IP address 10.0.0.1 and then can configure the switch with the web-based Express Setup program or the command-line interface (CLI)-based setup program.
When you press the Express Setup button for 2 seconds on a configured switch, the LEDs below the Express Setup button start blinking. If you press the Express Setup button for a total of 10 seconds, the switch configuration is deleted, and the switch reboots. The switch can then be configured like a new switch, either through the web-based Express Setup program or the CLI-based setup program.
Note As soon as you make any change to the switch configuration (including entering no at the ning of the CLI-based setup program), configuration by Express Setup is no longer available. You can only run Express Setup again by pressing the Express Setup button for 10 seconds. This deletes the switch configuration and reboots the switch.
If Express Setup is active on the switch, entering the
write memory
or
copy running-configuration startup-configuration
privileged EXEC commands deactivates Express Setup. The IP address 10.0.0.1 is no longer valid on the switch, and your connection using this IP address ends.
The primary purpose of the
no setup express
command is to prevent someone from deleting the switch configuration by pressing the Mode button for 10 seconds.
Examples
This example shows how to enable Express Setup mode:
Switch(config)# setup express
You can verify that Express Setup mode is enabled by pressing the Express Setup button:
-
On an unconfigured switch, the LEDs below the Express Setup button turn solid green after 3 seconds.
-
On a configured switch, the mode LEDs begin blinking after 2 seconds and turn solid green after 10 seconds.
Caution If you
hold the Express Setup button down for a total of 10 seconds, the configuration is deleted, and the switch reboots.
This example shows how to disable Express Setup mode:
Switch(config)# no setup express
You can verify that Express Setup mode is disabled by pressing the Express Setup button. The LEDs do not turn solid green
or
begin blinking green if Express Setup mode is not enabled on the switch.

BOOT path-list
|
Displays a semicolon separated list of executable files to try to load and execute when automatically booting up.
If the BOOT environment variable is not set, the system attempts to load and execute the first executable image it can find by using a recursive, depth-first search through the flash file system. In a depth-first search of a directory, each encountered subdirectory is completely searched before continuing the search in the original directory.
If the BOOT variable is set but the specified images cannot be loaded, the system attempts to boot up with the first bootable file that it can find in the flash file system.
|

|
Manual Boot
|
Displays whether the switch automatically or manually boots up. If it is set to no or 0, the bootloader attempts to automatically boot up the system. If it is set to anything else, you must manually boot up the switch from the bootloader mode.
|
Helper path-list
|
Displays a semicolon separated list of loadable files to dynamically load during the bootloader initialization. Helper files extend or patch the functionality of the bootloader.
|
Auto upgrade

Usage Guidelines
This command is available only on the cluster command switch.
If the switch is not a cluster command switch, the command displays an empty line at the prompt.
The SN in the display means
switch member number
. If E appears in the SN column, it means that the switch is discovered through extended discovery. If E does not appear in the SN column, it means that the
switch member number
is the upstream neighbor of the candidate switch. The hop count is the number of devices the candidate is from the cluster command switch.
Examples
This is an example of output from the
show cluster candidates
command:

The bit error-rate input to the switch is a positive exponent. The output displays the positive exponent; an output of 9 means that the bit error-rate is 10-9.
Examples
This is an example of output from the
show fcs-threshold
command. It shows the output when all ports are set to the default FCS threshold.

command:
Switch# show interfaces switchport backup Switch Backup Interface Pairs: Active Interface Backup Interface State -------------------------------------------------------------- Fa1/1 Fa1/2 Active Up/Backup Standby Fa1/3 Fa1/5 Active Down/Backup Up Po1 Po2 Active Standby/Backup Up
This is an example of output from the
show interfaces switchport backup
command. In this example, VLANs 1 to 50, 60, and 100 to 120 are configured on the switch:
Switch(config)#interface gigabitEthernet 1/1 Switch(config-if)#switchport backup interface gigabitEthernet 1/2 prefer vlan 60,100-120
When both interfaces are up, Gi1/2 forwards traffic for VLANs 60, 100 to 120, and Gi1/1 forwards traffic for VLANs 1 to 50.
Switch#show interfaces switchport backup Switch Backup Interface Pairs: Active Interface Backup Interface State ------------------------------------------------------------------------ GigabitEthernet1/1 GigabitEthernet1/2 Active Down/Backup Up Vlans on Interface Gi 1/1: 1-50 Vlans on Interface Gi 1/2: 60, 100-120
When a Flex Link interface goes down (LINK_DOWN), VLANs preferred on this interface are moved to the peer interface of the Flex Link pair. In this example, if interface Gi1/1 goes down, Gi1/2 carries all VLANs of the Flex Link pair.
Switch#show interfaces switchport backup Switch Backup Interface Pairs: Active Interface Backup Interface State ------------------------------------------------------------------------ GigabitEthernet1/1 GigabitEthernet1/2 Active Down/Backup Up Vlans on Interface Gi 1/1: Vlans on Interface Gi 1/2: 1-50, 60, 100-120
When a Flex Link interface comes up, VLANs preferred on this interface are blocked on the peer interface and moved to the forwarding state on the interface that has just come up. In this example, if interface Gi1/1 comes up, then VLANs preferred on this interface are blocked on the peer interface Gi1/2 and forwarded on Gi1/1.

Usage Guidelines
In the output for the
show interface rep
[
detail
] command, in addition to an
Open
,
Fail
, or AP (alternate port) state, the Port Role might show as
Fail Logical Open
(
FailLogOpen
) or
Fail No Ext Neighbor
(
FailNoNbr
). These states indicate that the port is physically up, but REP is not configured on the neighboring port. In this case, one port goes into a forwarding state for the data path to help maintain connectivity during configuration. The Port Role for this port shows as Fail Logical Open; the port forwards all data traffic on all VLANs. The other failed Port Role shows as
Fail No Ext Neighbor;
this port blocks traffic for all VLANs.
When the external neighbors for the failed ports are configured, the failed ports go through the alternate port state transitions and eventually go to an Open state or remain as the alternate port, based on the alternate port election mechanism.
In the
show interfaces rep
command output, ports configured as edge no-neighbors are designated with an asterisk (*) in front of
Primary Edge
or
Secondary Edge
. In the output of the
show interfaces rep detail
command,
No-Neighbor
is spelled out.
The output of this command is also included in the
show tech-support
privileged EXEC command output.

Table 2-28
shows the DHCP snooping statistics and their descriptions:
Table 2-28 DHCP Snooping Statistics
|
|
|
Packets Processed by DHCP Snooping
|
Total number of packets handled by DHCP snooping, including forwarded and dropped packets.
|
Packets Dropped Because IDB not known
|
Number of errors when the input interface of the packet cannot be determined.
|
Queue full
|
Number of errors when an internal queue used to process the packets is full. This might happen if DHCP packets are received at an excessively high rate and rate limiting is not enabled on the ingress ports.
|
Interface is in errdisabled
|
Number of times a packet was received on a port that has been marked as error disabled. This might happen if packets are in the processing queue when a port is put into the error-disabled state and those packets are subsequently processed.
|
Rate limit exceeded
|
Number of times the rate limit configured on the port was exceeded and the interface was put into the error-disabled state.
|
Received on untrusted ports
|
Number of times a DHCP server packet (OFFER, ACK, NAK, or LEASEQUERY) was received on an untrusted port and was dropped.
|
Nonzero giaddr
|
Number of times the relay agent address field (giaddr) in the DHCP packet received on an untrusted port was not zero, or the
no ip dhcp snooping information option allow-untrusted
global configuration command is not configured and a packet received on an untrusted port contained option-82 data.
|
Source mac not equal to chaddr
|
Number of times the client MAC address field of the DHCP packet (chaddr) does not match the packet source MAC address and the
ip dhcp snooping verify mac-address
global configuration command is configured.
|
Binding mismatch
|
Number of times a RELEASE or DECLINE packet was received on a port that is different than the port in the binding for that MAC address-VLAN pair. This indicates someone might be trying to spoof the real client, or it could mean that the client has moved to another port on the switch and issued a RELEASE or DECLINE. The MAC address is taken from the chaddr field of the DHCP packet, not the source MAC address in the Ethernet header.
|
Insertion of opt82 fail
|
Number of times the option-82 insertion into a packet failed. The insertion might fail if the packet with the option-82 data exceeds the size of a single physical packet on the internet.
|
Interface Down
|
Number of times the packet is a reply to the DHCP relay agent, but the SVI interface for the relay agent is down. This is an unlikely error that occurs if the SVI goes down between sending the client request to the DHCP server and receiving the response.
|
Unknown output interface
|
Number of times the output interface for a DHCP reply packet cannot be determined by either option-82 data or a lookup in the MAC address table. The packet is dropped. This can happen if option 82 is not used and the client MAC address has aged out. If IPSG is enabled with the port-security option and option 82 is not enabled, the MAC address of the client is not learned, and the reply packets will be dropped.
|
Reply output port equal to input port
|
Number of times the output port for a DHCP reply packet is the same as the input port, causing a possible loop. Indicates a possible network misconfiguration or misuse of trust settings on ports.
|
Packet denied by platform
|
Number of times the packet has been denied by a platform-specific registry.

Usage Guidelines
Use the
show ip igmp snooping querier
command to display the IGMP version and the IP address of a detected device, also called a
querier
, t
hat sends IGMP query messages. A subnet can have multiple multicast routers but has only one IGMP querier. In a subnet running IGMPv2, one of the multicast routers is elected as the querier. The querier can be a Layer 3 switch.
The
show ip igmp snooping querier
command output also shows the VLAN and the interface on which the querier was detected. If the querier is the switch, the output shows the
Port
field as
Router.
If the querier is a router, the output shows the port number on which the querier is learned in the
Port
field.
The
show ip igmp snooping querier detail
EXEC command is similar to the
show ip igmp snooping querier
command. However, the
show ip igmp snooping querier
command
displays only the device IP address most recently detected by the switch querier.
The
show ip igmp snooping querier detail
command di
splays the device IP address most recently detected by the switch querier and this additional information:
-
The elected IGMP querier in the VLAN
-
The configuration and operational information pertaining to the switch querier (if any) that is configured in the VLAN

In the previous example, this is the IP source guard configuration:
-
On the Gigabit Ethernet 1 interface, DHCP snooping is enabled on VLANs 10 to 20. For VLAN 10, IP source guard with IP address filtering is configured on the interface, and a binding exists on the interface. For VLANs 11 to 20, the second entry shows that a default port access control lists (ACLs) is applied on the interface for the VLANs on which IP source guard is not configured.
-
The Gigabit Ethernet 2 interface is configured as trusted for DHCP snooping.
-
On the Gigabit Ethernet 3 interface, DHCP snooping is not enabled on the VLANs to which the interface belongs.
-
On the Gigabit Ethernet 4 interface, IP source guard with source IP and MAC address filtering is enabled, and static IP source bindings are configured on VLANs 10 and 11. For VLANs 12 to 20, the default port ACL is applied on the interface for the VLANs on which IP source guard is not configured.
-
On the Gigabit Ethernet 5 interface, IP source guard with source IP and MAC address filtering is enabled and configured with a static IP binding, but port security is disabled. The switch cannot filter source MAC addresses.
This is an example of output on an interface on which IP source guard is disabled:
Switch> show ip verify source gigabitethernet 1/6 IP source guard is not configured on the interface gi1/16.

Usage Guidelines
Use the
show ipv6 mld snooping querier
command to display the MLD version and IPv6 address of a detected device that sends MLD query messages, which is also called a
querier
. A subnet can have multiple multicast routers but has only one MLD querier. The querier can be a Layer 3 switch.
Note This command is available only if you have configured a dual IPv4 and IPv6 Switch Database Management (SDM) template on the switch. To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 global configuration command and reload the switch.
The
show ipv6 mld snooping querier
command output also shows the VLAN and interface on which the querier was detected. If the querier is the switch, the output shows the
Port
field as
Router.
If the querier is a router, the output shows the port number on which the querier is learned in the
Port
field.
The output of the
show ipv6 mld snoop querier vlan
command displays the information received in response to a query message from an external or internal querier. It does not display user-configured VLAN values, such as the snooping robustness variable on the particular VLAN. This querier information is used only on the MASQ message that is sent by the switch. It does not override the user-configured robustness variable that is used for aging out a member that does not respond to query messages.
VLAN numbers 1002 through 1005 are reserved for Token Ring and FDDI VLANs and cannot be used in MLD snooping.

|
|
State
|
State of the specific port. These are the allowed values:
-
– —Port is in an unknown state.
-
bndl
—Port is attached to an aggregator and bundled with other ports.
-
susp
—Port is in a suspended state; it is not attached to any aggregator.
-
hot-sby
—Port is in a hot-standby state.
-
indiv
—Port is incapable of bundling with any other port.
-
indep
—Port is in an independent state (not bundled but able to switch data traffic. In this case, LACP is not running on the partner port).
-
down
—Port is down.
|
LACP Port Priority
|
Port priority setting. LACP uses the port priority to put ports s in standby mode when there is a hardware limitation that prevents all compatible ports from aggregating.
|
Admin Key
|
Administrative key assigned to this port. LACP automatically generates an administrative key value as a hexadecimal number. The administrative key defines the ability of a port to aggregate with other ports. A port’s ability to aggregate with other ports is determined by the port physical characteristics (for example, data rate and duplex capability) and configuration restrictions that you establish.
|
Oper Key
|
Runtime operational key that is being used by this port. LACP automatically generates this value as a hexadecimal number.
|
Port Number
|
Port number.
|
Port State
|
State variables for the port, encoded as individual bits within a single octet with these meanings:
-
bit0: LACP_Activity
-
bit1: LACP_Timeout
-
bit2: Aggregation
-
bit3: Synchronization
-
bit4: Collecting
-
bit5: Distributing
-
bit6: Defaulted
-
bit7: Expired
Note In the list above, bit7 is the MSB and bit0 is the LSB. |

The policed-DSCP, DSCP-to-CoS, and the DSCP-to-DSCP-mutation maps appear as a matrix. The d1 column specifies the most-significant digit in the DSCP. The d2 row specifies the least-significant digit in the DSCP. The intersection of the d1 and d2 values provides the policed-DSCP, the CoS, or the mutated-DSCP value. For example, in the DSCP-to-CoS map, a DSCP value of 43 corresponds to a CoS value of 5.
The DSCP input queue threshold and the DSCP output queue threshold maps appear as a matrix. The d1 column specifies the most-significant digit of the DSCP number. The d2 row specifies the least-significant digit in the DSCP number. The intersection of the d1 and the d2 values provides the queue ID and threshold ID. For example, in the DSCP input queue threshold map, a DSCP value of 43 corresponds to queue 2 and threshold 1 (02-01).
The CoS input queue threshold and the CoS output queue threshold maps show the CoS value in the top row and the corresponding queue ID and threshold ID in the second row. For example, in the CoS input queue threshold map, a CoS value of 5 corresponds to queue 2 and threshold 1 (2-1).

Usage Guidelines
When you change the SDM template by using the
sdm prefer
global configuration command, you must reload the switch for the configuration to take effect. If you enter the
show sdm prefer
command before you enter the
reload
privileged EXEC command, the
show sdm prefer
command shows the template currently in use and the template that will become active after a reload.
The numbers displayed for each template represent an approximate maximum number for each feature resource. The actual number might vary, depending on the actual number of other features configured.
Expressions are case sensitive. For example, if you enter
|
exclude output
, the lines that contain
output
do not appear, but the lines that contain
Output
appear.

Table 2-34 show udld Field Descriptions
|
|
|
Interface
|
The interface on the local device configured for UDLD.
|
Port enable administrative configuration setting
|
How UDLD is configured on the port. If UDLD is enabled or disabled, the port enable configuration setting is the same as the operational enable state. Otherwise, the enable operational setting depends on the global enable setting.
|
Port enable operational state
|
Operational state that shows whether UDLD is actually running on this port.
|
Current bidirectional state
|
The bidirectional state of the link. An unknown state appears if the link is down or if it is connected to an UDLD-incapable device. A bidirectional state appears if the link is a normal two-way connection to a UDLD-capable device. All other values mean miswiring.
|
Current operational state
|
The current phase of the UDLD state machine. For a normal bidirectional link, the state machine is most often in the Advertisement phase.
|
Message interval
|
How often advertisement messages are sent from the local device. Measured in seconds.
|
Time out interval
|
The time period, in seconds, that UDLD waits for echoes from a neighbor device during the detection window.
|
Entry 1
|
Information from the first cache entry, which contains a copy of echo information received from the neighbor.
|
Expiration time
|
The amount of time in seconds remaining before this cache entry is aged out.
|
Device ID
|
The neighbor device identification.
|
Current neighbor state
|
The neighbor’s current state. If both the local and neighbor devices are running UDLD normally, the neighbor state and local state should be bidirectional. If the link is down or the neighbor is not UDLD-capable, no cache entries appear.
|
Device name
|
The device name or the system serial number of the neighbor. The system serial number appears if the device name is not set or is set to the default (Switch).
|
Port ID
|
The neighbor port ID enabled for UDLD.
|
Neighbor echo 1 device
|
The device name of the neighbors’ neighbor from which the echo originated.
|
Neighbor echo 1 port
|
The port number ID of the neighbor from which the echo originated.
|
Message interval
|
The rate, in seconds, at which the neighbor is sending advertisement messages.
|
CDP device name
|
The CDP device name or the system serial number. The system serial number appears if the device name is not set or is set to the default (Switch).
|

Usage Guidelines
In the
show vlan mtu
command output, the
MTU_Mismatch
column shows whether all the ports in the VLAN have the same MTU. When
yes
appears in this column, it means that the VLAN has ports with different MTUs, and packets that are switched from a port with a larger MTU to a port with a smaller MTU might be dropped. If the VLAN does not have an SVI, the hyphen (-) symbol appears in the SVI_MTU column. If the MTU-Mismatch column displays
yes
, the names of the port with the MinMTU and the port with the MaxMTU appear.
If you try to associate a private VLAN secondary VLAN with a primary VLAN before you define the secondary VLAN, the secondary VLAN is not included in the
show vlan private-vlan
command output.
In the
show vlan private-vlan type
command output, a type displayed as
normal
means a VLAN that has a private VLAN association but is not part of the private VLAN. For example, if you define and associate two VLANs as primary and secondary VLANs and then delete the secondary VLAN configuration without removing the association from the primary VLAN, the VLAN that was the secondary VLAN is shown as
normal
in the display. In the
show vlan private-vlan
output, the primary and secondary VLAN pair is shown as
non-operational
.
Expressions are case sensitive. For example, if you enter |
exclude output
, the lines that contain
output
do not appear, but the lines that contain
Output
appear.

|
VQP Queries
|
Number of queries sent by the client to the VMPS.
|
VQP Responses
|
Number of responses sent to the client from the VMPS.
|
VMPS Changes
|
Number of times that the VMPS changed from one server to another.
|
VQP Shutdowns
|
Number of times the VMPS sent a response to shut down the port. The client disables the port and removes all dynamic addresses on this port from the address table. You must administratively re-enable the port to restore connectivity.
|
VQP Denied
|
Number of times the VMPS denied the client request for security reasons. When the VMPS response denies an address, no frame is forwarded to or from the workstation with that address (broadcast or multicast frames are delivered to the workstation if the port has been assigned to a VLAN). The client keeps the denied address in the address table as a blocked address to prevent more queries from being sent to the VMPS for each new packet received from this workstation. The client ages the address if no new packets are received from this workstation on this port within the aging time period.
|
VQP Wrong Domain
|
Number of times the management domain in the request does not match the one for the VMPS. Any previous VLAN assignments of the port are not changed. This response means that the server and the client have not been configured with the same VTP management domain.
|
VQP Wrong Version
|
Number of times the version field in the query packet contains a value that is higher than the version supported by the VMPS. The VLAN assignment of the port is not changed. The switches send only VMPS Version 1 requests.
|
VQP Insufficient Resource
|
Number of times the VMPS is unable to answer the request because of a resource availability problem. If the retry limit has not yet been reached, the client repeats the request with the same server or with the next alternate server, depending on whether the per-server retry count has been reached.

Table 2-37 show vtp counters Field Descriptions
|
|
|
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 timestamp 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 configuration revision errors
|
Number of revision errors.
Whenever you define a new VLAN, delete an existing one, 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 means that the VTP password in the two switches is different or that the switches have different configurations.
These errors means that the switch is filtering incoming advertisements, which causes the VTP database to become unsynchronized across the network.
|
Number of configuration 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 means 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 mean 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 mean 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 sent 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.
|
This is an example of output from the
show vtp status
command for a switch running VTP version 2.

|
VTP Version
|
Displays the VTP version operating on the switch. By default, the switch implements 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 the VLAN information in the current VTP database from NVRAM after reboot. By default, every switch is a VTP server.
Note The switch automatically changes from VTP server mode to VTP client mode if it detects a failure while writing the configuration to NVRAM and cannot return to server mode until the NVRAM is functioning.
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 send VTP advertisements until it receives advertisements to initialize its VLAN database.
Transparent: a switch in VTP transparent mode is disabled for VTP, does not send 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.
|
VTP Domain Name
|
Name that identifies the administrative domain for the switch.
|
VTP Pruning Mode
|
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 the 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 sent to a network management station.
|
MD5 Digest
|
A 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.
