Usage Guidelines
The show auto qos interface command can be used with Frame Relay data-link connection identifiers (DLCIs) and ATM permanent virtual circuits (PVCs).
When the AutoQoS—VoIP or the AutoQos for the Enterprise features are enabled, configurations are generated for each interface or PVC. These configurations are then used to create the interface configurations, policy maps, class maps, and access control lists (ACLs) for use on the network. The show auto qos command can be used to verify the contents of the interface configurations, policy maps, class maps, and ACLs.
Catalyst 6500 Series Switches

Usage Guidelines
Use the show ip nbar protocol-discovery command to display statistics gathered by the NBAR Protocol Discovery feature. This command, by default, displays statistics for all interfaces on which protocol discovery is currently enabled. The default output of this command includes, in the following order, input bit rate (in bits per second), input byte count, input packet count, and protocol name.
Protocol discovery can be used to monitor both input and output traffic and may be applied with or without a service policy enabled. NBAR protocol discovery gathers statistics for packets switched to output interfaces. These statistics are not necessarily for packets that exited the router on the output interfaces, because packets may have been dropped after switching for various reasons, including policing at the output interface, access lists, or queue drops.
Layer 2/3 Etherchannel Support
With Cisco IOS Release 12.2(18)ZYA, intended for use on the Cisco 6500 series switch that is equipped with a Supervisor 32/programmable intelligent services accelerator (PISA), the show ip nbar protocol-discovery command is supported on both Layer 2 and Layer 3 Etherchannels.
Examples
The following example displays output from the show ip nbar protocol-discovery command for the five most active protocols on an Ethernet interface:
Router# show ip nbar protocol-discovery top-n 5

Usage Guidelines
The show ip nbar version command treats all protocols that were added to NBAR after the initial NBAR release as PDLMs, including protocols that were added into the Cisco IOS software without a user having to download a PDLM from Cisco.com. PDLMs downloaded from Cisco.com and incorporated into NBAR by the user also appear when the show ip nbar version command is entered.
When using NBAR, various elements within NBAR are assigned versioning numbers. These versioning numbers become significant when you want to download a PDLM. PDLMs, which are also versioned, can be downloaded only to NBAR on a particular Cisco IOS release if the PDLM versioning numbers are compatible with the NBAR version numbers in the Cisco IOS software.
The following NBAR-related version information is available:
•NBAR Software Version—Version of NBAR software running on the current version of Cisco IOS software.
•Resident Module Version—Version of the NBAR-supported PDLM protocol.
The following version number is kept by the PDLM:
•NBAR Software Version—Minimum version of the NBAR software that is required to load this PDLM.
The show ip nbar version command provides version information for PDLMs already loaded onto the Cisco IOS software.
Examples
The following is sample output from the show ip nbar version command:
Router# show ip nbar version
3 http Mv: 7, Nv: 3; slot1:http_vers.pdlm
16 kazaa Mv: 6, Nv: 3; slot1:kazaa2_vers.pdlm

|
Keys can be either static (manually configured) or dynamic (created from a per-ACL key or obtained from a key management server such as Kerberos). Cisco IOS software does not currently support dynamic keys from key management servers. If the field contains the string per-neighbor, it means the security association is using a per-neighbor key; if the field contains the string per-interface, it means the security association is using a per-interface key. If the field contains the string chain, it means the key for the security association comes from the key chain specified in the Key Source.
|
From
|
Starting point of the security association.
|
To
|
Ending point of the security association.
|
I/F
|
Name and number of the interface over which the security association is being maintained.
|
Mode
|
Separate associations maintained for sending and receiving RSVP messages for a specific RSVP neighbor. Possible values are Send or Receive.
|
Key-Source
|
Indicates where the key was configured.
|
Key-ID
|
A string which, along with the IP address, uniquely identifies a security association. The key ID is automatically generated in Cisco IOS software by using the per-interface ip rsvp authentication key command, but it is configured in Cisco IOS software when using key chains for per-neighbor or per-interface RSVP keys. The key ID may be configurable on other RSVP platforms. A key ID is provided in every RSVP authenticated message initiated by a sender and is stored by every RSVP receiver.
Note Key Expired in this field means that all possible keys used for this neighbor have expired.

Key ID
|
A string which, along with the IP address, uniquely identifies a security association. The key ID is automatically generated in Cisco IOS software by using the per-interface ip rsvp authentication key command, but it is configured in Cisco IOS software when using key chains for per-neighbor or per-interface RSVP keys. The key ID may be configurable on other RSVP platforms. A key ID is provided in every RSVP authenticated message initiated by a sender and is stored by every RSVP receiver.
Note Key Expired in this field means that all possible keys used for this neighbor have expired.
|
Key ACL
|
For key types that say dynamic and chain, this field indicates which ACL matched that neighbor, and therefore, which key chain to use. Possible values include:
•populated = ACL has entries in it.
•removed = ACL has been removed from the configuration.
|
Key Source
|
Indicates where the key was configured and whether it is enabled or disabled. For key chains, this indicates the name of the key chain; the Key ID field indicates which key in the chain is currently being used. For per-interface keys, this field contains the name of the interface that was configured with the key.
|
Key Type
|
Static (manually configured) or dynamic (created from a per-ACL key or obtained from a key management server such as Kerberos).
Note Cisco IOS software does not currently support dynamic keys from key management servers.
|
Handle
|
Internal database ID assigned to the security association by RSVP for bookkeeping purposes.
|
Hash Type
|
Type of secure hash algorithm being used with that neighbor.
|
Lifetime
|
Maximum amount of time (in hours, minutes, and seconds) that can elapse before a security association is expired.
Note This is not how long a key is valid; to obtain duration times for keys, use the show key chain command.
|
Expires
|
Amount of time remaining (in days, hours, minutes, and seconds) before the security association expires.
Note This is not when the current key expires; to obtain expiration times for keys, use the show key chain command.
|
Challenge
|
For receive-type security associations, possible values are Not Configured, Completed, In Progress, and Failed. For send-type security associations, the value is Supported. Cisco IOS software can always respond to challenges; however, there may be non-Cisco neighbors that do not implement challenges.
|
Window size
|
Indicates the size of the window for receive-type security associations and the maximum number of authenticated RSVP messages that can be received out-of-order before a replay attack is to be suspected.
|
Last seq # sent
|
Displayed only for send-type security associations. It indicates the sequence number used to send the last authenticated message to the RSVP neighbor. Use this information to troubleshoot certain types of authentication problems.
|
Last valid seq # rcvd
|
Displayed only for receive-type security associations. It indicates the authentication sequence number of the last valid RSVP message received from the neighbor. By default, it shows only one sequence number. However, if you use the ip rsvp authentication window-size command to increase the authentication window size to n, then the last n valid received sequence numbers are displayed. Use this information to troubleshoot certain types of authentication problems.

Field
|
Description
|
Tun Dest
|
IP address of the receiver.
|
Tun ID
|
Tunnel identification number.
|
Ext Tun ID
|
Extended tunnel identification number.
|
Tun Sender
|
IP address of the sender.
|
LSP ID
|
Label-switched path identification number.
|
Setup Prio
|
Setup priority.
|
Holding Prio
|
Holding priority.
|
Flags
|
Backup bandwidth protection has been configured for the label-switched path (LSP).
|
Session Name
|
Name of the session.
|
ERO (incoming)
|
EXPLICIT_ROUTE object of incoming path messages.
|
ERO (outgoing)
|
EXPLICIT_ROUTE object of outgoing path messages.
|
Traffic params Rate
|
Average rate, in bits per second.
|
Max. burst
|
Maximum burst size, in bytes.
|
Min Policed Unit
|
Minimum policed units, in bytes.
|
Max Pkt Size
|
Maximum packet size, in bytes.
|
Inbound FRR
|
Status of inbound Fast Reroute (FRR) backup tunnel. If this node is downstream from a rerouted LSP (for example, at a merge point for this LSP), the state is Active.
|
Outbound FRR
|
Status of outbound FRR backup tunnel. If this node is a point of local repair (PLR) for an LSP, there are three possible states:
•Active—This LSP is actively using its backup tunnel, presumably because there has been a downstream failure.
•No Backup—This LSP does not have local (Fast Reroute) protection. No backup tunnel has been selected for it to use in case of a failure.
•Ready—This LSP is ready to use a backup tunnel in case of a downstream link or node failure. A backup tunnel has been selected for it to use.
|
Backup Tunnel
|
If the Outbound FRR state is Ready or Active, this field indicates the following:
•Which backup tunnel has been selected for this LSP to use in case of a failure.
•The inbound label that will be prepended to the LSP's data packets for acceptance at the backup tunnel tail (the merge point).
|
Bkup Sender Template
|
If the Outbound FRR state is Ready or Active, SENDER_TEMPLATE and FILTERSPEC objects are shown. These objects will be used in RSVP messages sent by the backup tunnel if or when the LSP starts actively using the backup tunnel. They differ from the original (prefailure) objects only in that the node (the PLR) substitutes its own IP address for that of the original sender. For example, path and pathTear messages will contain the new SENDER_TEMPLATE. Resv and resvTear messages will contain the new FILTERSPEC object. If this LSP begins actively using the backup tunnel, the display changes.
|
Bkup FilerSpec
|
If the Outbound FRR state is Ready or Active, SENDER_TEMPLATE and FILTERSPEC objects are shown. These objects will be used in RSVP messages sent by the backup tunnel if or when the LSP starts actively using the backup tunnel. They differ from the original (prefailure) objects only in that the node (the PLR) substitutes its own IP address for that of the original sender. For example, path and pathTear messages will contain the new SENDER_TEMPLATE. Resv and resvTear messages will contain the new FILTERSPEC object. If this LSP begins actively using the backup tunnel, the display changes.
|
Path ID handle
|
Protection Switch Byte (PSB) identifier.
|
Incoming policy
|
Policy decision of the LSP. If RSVP policy was not granted for the incoming path message for the tunnel, the LSP does not come up. Accepted is displayed.
|
Policy source(s)
|
For FRR LSPs, this value always is MPLS/TE for the policy source.
|
Status
|
For FRR LSPs, valid values are as follows:
•Proxied—Headend routers.
•Proxied Terminated—Tailend routers.
For midpoint routers, the field always is blank.
