Modification

11.3T

This command was introduced.

12.2(13)T

The command output was expanded to include a warning message for users who try to configure an IKE encryption method that the hardware does not support.

12.4(4)T

Support for IPv6 was added.

12.2(33)SRA

This command was integrated into Cisco IOS Release 12.(33)SRA.

12.2SX

This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

12.4(20)T

The command output was expanded to include default IKE policies.

Cisco IOS XE Release 2.4

This command was implemented on the Cisco ASR 1000 series routers.


Usage Guidelines

There are eight default IKE default policies supported with protection suites of priorities 65507-65514, where 65507 is the highest priority and 65514 is the lowest priority. If you have neither manually configured IKE policies with the crypto isakmp policy command nor disabled the default IKE policies by issuing the no crypto isakmp default policy command, the default IKE policies will be displayed when the show crypto isakmp policy command is issued.

Examples

The following is sample output from the show crypto isakmp policy command, after two IKE policies have been configured (with priorities 15 and 20, respectively):

Router# show crypto isakmp policy

Protection suite priority 15
        encryption algorithm:    DES - Data Encryption Standard (56 bit keys)
        hash algorithm:  Message Digest 5
        authentication method:   Rivest-Shamir-Adleman Signature
        Diffie-Hellman Group:    #2 (1024 bit)
        lifetime:      5000 seconds, no volume limit
Protection suite priority 20
        encryption algorithm:    DES - Data Encryption Standard (56 bit keys)
        hash algorithm: Secure Hash Standard
        authentication method:   preshared Key
        Diffie-Hellman Group:    #1 (768 bit)
        lifetime:      10000 seconds, no volume limit
Default protection suite
        encryption algorithm:    DES - Data Encryption Standard (56 bit keys)
        hash algorithm: Secure Hash Standard
        authentication method:   Rivest-Shamir-Adleman Signature
        Diffie-Hellman Group:    #1 (768 bit)
        lifetime:      86400 seconds, no volume limit

Note Although the output shows "no volume limit" for the lifetimes, you can currently configure only a time lifetime (such as 86,400 seconds); volume limit lifetimes are not used.


The following sample output from the show crypto isakmp policy command displays a warning message after a user tries to configure an IKE encryption method that the hardware does not support:

Router# show crypto isakmp policy

Protection suite of priority 1
        encryption algorithm:  AES - Advanced Encryption Standard (256 bit keys).
WARNING:encryption hardware does not support the configured
encryption method for ISAKMP policy 1
        hash algorithm:        Secure Hash Standard
        authentication method: Pre-Shared Key
        Diffie-Hellman group:  #1 (768 bit)
        lifetime:              3600 seconds, no volume limit

The following sample output from the show crypto isakmp policy command displays the default IKE policies. The manually configured IKE policies with priorities 10 and 20 have been removed.

Router(config)# no crypto isakmp policy 10
Router(config)# no crypto isakmp policy 20

Usage Guidelines

The show crypto map command allows you to specify a particular crypto map. The crypto maps shown in the command output are dynamically generated; you need not configure crypto maps in order for them to appear in this command output.

Two default transform sets are supported in Cisco IOS K9 images only:

Esp-aes esp-sha-hmac

Esp-3des esp-sha-hmac

The show crypto map command displays the default transform sets if no other transform sets are configured for the crypto map, if you have not disabled the default transform sets by issuing the no crypto ipsec default transform-set command, and if the crypto engine supports the encryption algorithm.

Examples

The following example shows that crypto input and output ACLs have been configured:

Router# show crypto map

Table 66 describes the significant fields shown in the display.

Table 66 show crypto map Field Descriptions 

Field
Description

Peer

Possible peers that are configured for this crypto map entry.

Extended IP access list

Access list that is used to define the data packets that need to be encrypted. Packets that are denied by this access list are forwarded but not encrypted. The "reverse" of this access list is used to check the inbound return packets, which are also encrypted. Packets that are denied by the "reverse" access list are dropped because they should have been encrypted but were not.

Extended IP access check

Access lists that are used to more finely control which data packets are allowed into or out of the IPsec tunnel. Packets that are allowed by the "Extended IP access list" ACL but denied by the "Extended IP access list check" ACL are dropped.

Current peer

Current peer that is being used for this crypto map entry.

Security association lifetime

Number of bytes that are allowed to be encrypted or decrypted or the age of the security association before new encryption keys must be negotiated.

PFS

(Perfect Forward Secrecy) If the field is marked as `Yes', the Internet Security Association and Key Management Protocol (ISAKMP) SKEYID-d key is renegotiated each time security association (SA) encryption keys are renegotiated (requires another Diffie-Hillman calculation). If the field is marked as `No', the same ISAKMP SKEYID-d key is used when renegotiating SA encryption keys. ISAKMP keys are renegotiated on a separate schedule, with a default time of 24 hours.

Transform sets

List of transform sets (encryption, authentication, and compression algorithms) that can be used with this crypto map.

Interfaces using crypto map test

Interfaces to which this crypto map is applied. Packets that are leaving from this interface are subject to the rules of this crypto map for encryption. Encrypted packets may enter the router on any interface, and they are decrypted. Nonencrypted packets that are entering the router through this interface are subject to the "reverse" crypto access list check.


The following example displays output from the show crypto map command. No transform sets are configured for the crypto map "mymap," the default transform sets are enabled, and the crypto engine supports the encryption algorithm.

Router# show crypto map 

Crypto Map "mymap" 1 ipsec-isakmp
        Peer = 209.165.201.1
        Extended IP access list 102

        Transform sets={ 
        }


! There are no transform sets for the crypto map "mymap."
        Reverse Route Injection Enabled
        Interfaces using crypto map mymap:

The following example displays output for the show crypto map command and gdoi fail-close keywords (show crypto map gdoi fail-close). Fail-close has been activated. In addition, an implicit "permit ip any any" entry is configured, causing any traffic other than Telnet and Open Shortest Path First (OSPF) to be dropped:

Router# show crypto map gdoi fail-close 23

Crypto Map: "svn" 
        Activate: yes
        Fail-Close Access-List: (Deny = Forward In Clear, Permit = Drop)

The following is sample output from the show dial-peer voice summary command that shows connected FXO port 0/2/0 (the last entry) has OUT STAT set to "up," which indicates that the POTS dial peer can be used for an outgoing call. If this port is disconnected, the status changes in the output so that the OUT STAT field reports "down," and the POTS dial peer cannot be used for an outgoing call.


Note Beginning in Cisco IOS Release 15.1(3)T, there is improved status monitoring of FXO ports—any time an FXO port is connected or disconnected, a message is displayed to indicate the status change. For example, the following message is displayed to report that a cable has been connected, and the status is changed to "up" for FXO port 0/2/0:

000118: Jul 14 18:06:05.122 EST: %LINK-3-UPDOWN: Interface Foreign Exchange Office 0/2/0, changed state to operational status up due to cable reconnection

If an interface is specified, only information about that interface is displayed. Otherwise, information about all interfaces on which EIGRP is running is displayed.

If an autonomous system is specified, only the routing process for the specified autonomous system is displayed. Otherwise, all EIGRP processes are displayed.

This command can be used to display information about EIGRP named configurations and EIGRP autonomous-system (AS) configurations.

This command displays the same information as the show ip eigrp interfaces command. Cisco recommends using the show eigrp address-family interfaces command.

Examples

The following example shows how to display information about EIGRP interfaces for autonomous-system 4453:

Router# show eigrp address-family ipv4 4453 interfaces

Table 76 describes the significant fields shown in the display.

Table 76 show eigrp address-family topology Field Descriptions 

Field
Description

Codes

State of this topology table entry. Passive and Active refer to the EIGRP state with respect to this destination; Update, Query, and Reply refer to the type of packet that is being sent.

P—Passive

No EIGRP computations are being performed for this destination.

A—Active

EIGRP computations are being performed for this destination.

U—Update

An update packet was sent to this destination.

Q—Query

A query packet was sent to this destination.

R—Reply

A reply packet was sent to this destination.

r—reply Status

Flag that is set after the software has sent a query and is waiting for a reply.

s—sia Status

Flag that is set if a route is in a stuck in active state.

successors

Number of successors. This number corresponds to the number of next hops in the IP routing table. If "successors" is capitalized, then the route or next hop is in a transition state.

FD

Feasible distance. The feasible distance is the best metric to reach the destination or the best metric that was known when the route went active. This value is used in the feasibility condition check. If the reported distance of the router (the metric after the slash) is less than the feasible distance, the feasibility condition is met and that path is a feasible successor. Once the software determines it has a feasible successor, it need not send a query for that destination.

replies

(Not shown in the output.) Number of replies that are still outstanding (have not been received) with respect to this destination. This information appears only when the destination is in the Active state.

state

(Not shown in the output) Exact EIGRP state that this destination is in. It can be the number 0, 1, 2, or 3. This information appears only when the destination is in the Active state.

via

IP address of the peer that told the software about this destination. The first N of these entries, where N is the number of successors, is the current successors. The remaining entries on the list are feasible successors.

(409600/128256)

The first number is the EIGRP metric that represents the cost to the destination. The second number is the EIGRP metric that this peer advertised.

Ethernet3/0

Interface from which this information was learned.

Display Maps for IPv6 Addresses: Example

The sample output in this example uses the following router configuration:

hostname router1
!
interface Serial2/0
 no ip address
 encapsulation frame-relay
!
interface Serial2/0.1 point-to-point
 ipv6 address 1::1/64
 frame-relay interface-dlci 101   
!
interface Serial2/0.2 multipoint
 ipv6 address 2::1/64
 frame-relay map ipv6 2::2 201
 frame-relay interface-dlci 201   
! 
 
hostname router2
!
interface Serial3/3
 no ip address
 encapsulation frame-relay
 frame-relay intf-type dce
!
interface Serial3/3.1 point-to-point
 ipv6 address 1::2/64
 frame-relay interface-dlci 101   
!
interface Serial3/3.2 multipoint
 ipv6 address 2::2/64
 frame-relay map ipv6 3::1 201
 frame-relay interface-dlci 201
!

The following sample output from the show frame-relay map command shows that the link-local and global IPv6 addresses (FE80::E0:F727:E400:A and 2001:0DB8:2222:1044::32; FE80::60:3E47:AC8:8 and 2001:0DB8:2222:1044::32) of two remote nodes are explicitly mapped to DLCI 17 and DLCI 19, respectively. Both DLCI 17 and DLCI 19 are terminated on interface serial 3 of this node; therefore, interface serial 3 of this node is a point-to-multipoint interface.

Field
Description

Bundle

Bundle interface.

State

Operational state of the bundle interface.

class

The bandwidth class criterion used to activate or deactivate a Frame Relay bundle.

Class A (single link)—The bundle activates when any bundle link is up and deactivates when all bundle links are down (default).

Class B (all links)—The bundle activates when all bundle links are up and deactivates when any bundle link is down.

Class C (threshold)—The bundle activates when the minimum configured number of bundle links (the threshold) is up and deactivates when the minimum number of configured bundle links fails to meet the threshold.

BID

Bundle identification.

Bundle links

Bundle links for which information is displayed.

HW state

Operational state of the physical link.

Protocol state

Operational state of the bundle link line protocol.

link state

Operational state of the bundle link.

LID

Bundle link identification.

Bundle interface

Bundle interface with which the bundle link is associated.

Cause code

Can be one of the following values:

ack timer expiry—Add link synchronization process is exhausted.

bundle link idle—Peer's bundle link is idle. This usually occurs when the peer's bundle interface is shut down.

inconsistent bundle—Peer already has this bundle associated with another bundle.

loopback detected—Local bundle link's physical line is looped back.

none—ADD_LINK and ADD_LINK_ACK messages were properly exchanged, and no cause code was recorded.

other—Indicates one of the following: a link identifier (LID) mismatch, an ID from the peer that is too long, or a failure to allocate ID memory.

unexpected Add_link—ADD_LINK message is received when the bundle link is already in the "up" state. This code might appear when the line protocol is being set up, but will disappear once the connection is stabilized.

Ack timer

Number of seconds for which the bundle link waits for a hello acknowledgment before resending a hello message or resending an ADD_LINK message used for initial synchronization.

Hello timer

Interval at which a bundle link sends out hello messages.

Max retry count

12.4(9)T

The summary and all keywords were added, and support was added for hierarchical queueing framework (HQF).

12.2(33)SRA

This command was integrated into Cisco IOS Release 12.2(33)SRA.

Usage Guidelines

Use this command to monitor the PPP link control protocol (LCP) state as being open with an up state or closed with a down state.

When "vofr" or "vofr cisco" has been configured on the PVC, and a voice bandwidth has been allocated to the class associated with this PVC, configured voice bandwidth and used voice bandwidth are also displayed.

Statistics Reporting

To obtain statistics about PVCs on all Frame Relay interfaces, use this command with no arguments.

To obtain statistics about a PVC that include policy-map configuration or the priority configured for that PVC, use this command with the dlci argument.

To display a summary of all PVCs on the system, use the show frame-relay pvc command with the summary keyword. To display a summary of all PVCs per interface, use the summary all keywords.

Per-VC counters are not incremented at all when either autonomous or silicon switching engine (SSE) switching is configured; therefore, PVC values will be inaccurate if either switching method is used.

You can change the period of time over which a set of data is used for computing load statistics. If you decrease the load interval, the average statistics are computed over a shorter period of time and are more responsive to bursts of traffic. To change the length of time for which a set of data is used to compute load statistics for a PVC, use the load-interval command in Frame-Relay DLCI configuration mode.

Traffic Shaping

Congestion control mechanisms are currently not supported on terminated PVCs nor on PVCs over ISDN. Where congestion control mechanisms are supported, the switch passes forward explicit congestion notification (FECN) bits, backward explicit congestion notification (BECN) bits, and discard eligible (DE) bits unchanged from entry points to exit points in the network.

Table 84 describes the significant fields shown in the displays.

Table 84 show glbp Field Descriptions 

Field
Description

FastEthernet0/0 - Group

Interface type and number and GLBP group number for the interface.

State is

State of the virtual gateway or virtual forwarder. For a virtual gateway, the state can be one of the following:

Active—The gateway is the active virtual gateway (AVG) and is responsible for responding to Address Resolution Protocol (ARP) requests for the virtual IP address.

Disabled—The virtual IP address has not been configured or learned yet, but another GLBP configuration exists.

Initial—The virtual IP address has been configured or learned, but virtual gateway configuration is not complete. An interface must be up and configured to route IP, and an interface IP address must be configured.

Listen—The virtual gateway is receiving hello packets and is ready to change to the "speak" state if the active or standby virtual gateway becomes unavailable.

Speak—The virtual gateway is attempting to become the active or standby virtual gateway.

Standby—The gateway is next in line to be the AVG.

 

For a virtual forwarder, the state can be one of the following:

Active—The gateway is the active virtual forwarder (AVF) and is responsible for forwarding packets sent to the virtual forwarder MAC address.

Disabled—The virtual MAC address has not been assigned or learned. This is a transitory state because a virtual forwarder changing to a disabled state is deleted.

Initial—The virtual MAC address is known, but virtual forwarder configuration is not complete. An interface must be up and configured to route IP, an interface IP address must be configured, and the virtual IP address must be known.

Listen—The virtual forwarder is receiving hello packets and is ready to change to the "active" state if the AVF becomes unavailable.

Virtual IP address is

The virtual IP address of the GLBP group. All secondary virtual IP addresses are listed on separate lines. If one of the virtual IP addresses is a duplicate of an address configured for another device, it will be marked as "duplicate." A duplicate address indicates that the router has failed to defend its ARP cache entry.

Hello time, hold time

The hello time is the time between hello packets (in seconds or milliseconds). The hold time is the time (in seconds or milliseconds) before other routers declare the active router to be down. All routers in a GLBP group use the hello- and hold-time values of the current AVG. If the locally configured values are different, the configured values appear in parentheses after the hello- and hold-time values.

Next hello sent in

The time until GLBP will send the next hello packet (in seconds or milliseconds).

Preemption

Whether GLBP gateway preemption is enabled. If enabled, the minimum delay is the time (in seconds) for which a higher-priority nonactive router will wait before preempting the lower-priority active router.

This field is also displayed under the forwarder section where it indicates GLBP forwarder preemption.

Active is

The active state of the virtual gateway. The value can be "local," "unknown," or an IP address. The address (and the expiration date of the address) is the address of the current AVG.

This field is also displayed under the forwarder section where it indicates the address of the current AVF.

Standby is

The standby state of the virtual gateway. The value can be "local," "unknown," or an IP address. The address (and the expiration date of the address) is the address of the standby gateway (the gateway that is next in line to be the AVG).

Weighting

The initial weighting value with lower and upper threshold values.

Track object

The list of objects that are being tracked and their corresponding states.

IP redundancy name is

The name of the GLBP group.


Related Commands

Command
Description

glbp ip

Enables GLBP.

glbp timers

Configures the time between hello messages and the time before other routers declare the active GLBP router to be down.

glbp weighting track

Specifies an object to be tracked that affects the weighting of a GLBP gateway.


show interfaces accounting

To display the number of packets of each protocol type that have been sent through all configured interfaces, use the show interfaces accounting command in user EXEC or privileged EXEC mode.

show interfaces [interface type number | null interface-number | vlan vlan-id] accounting

Syntax Description

interface

(Optional) Interface type; possible valid values are ethernet, fastethernet, gigabitethernet, tengigabitethernet, pos, and port-channel, atm, and ge-wan.

type number

(Optional) Module and port number; see the "Usage Guidelines" section for valid values.

null interface-number

(Optional) Specifies the null interface; the valid value is 0.

vlan vlan-id

(Optional) Specifies the VLAN ID; valid values are from 1 to 4094.

12.2(33)SB

This command was integrated into Cisco IOS Release 12.2(33)SB.

Cisco IOS XE Release 2.1

This command was introduced on Cisco ASR 1000 Series Routers.


Usage Guidelines


Note The Pkts Out and Chars Out fields display IPv6 packet counts only. The Pkts In and Chars In fields display both IPv4 and IPv6 packet counts, except for tunnel interfaces. For tunnel interfaces, the IPv6 input packets are counted as IPv6 packets only.


Due to hardware limitations on the ASIC, PFC IPv4 and IPv6 packets cannot be differentiated in the Pkts In and Chars In fields for IP count the IPv6 and IPv4 packets that are hardware forwarded. The Pkts In and Chars In fields for IPv6 only count software-forwarded packets. The IP Pkts Out and Chars Out fields show IPv4 packets, and the IPv6 Pkts Out and Chars Out fields show IPv6 packets.

The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 1 to 13 and valid values for the port number are from 1 to 48.

The port channels from 257 to 282 are internally allocated and are supported on the CSM and the FWSM only.

If you do not enter any keywords, all counters for all modules are displayed.

Examples

This example shows how to display the number of packets of each protocol type that have been sent through all configured interfaces:

Router> show interfaces gigabitethernet 5/2 accounting

Usage Guidelines

The show ipv6 access-list command provides output similar to the show ip access-list command, except that it is IPv6-specific.

Examples

The following output from the show ipv6 access-list command shows IPv6 access lists named inbound, tcptraffic, and outbound:

Router# show ipv6 access-list

IPv6 access list inbound
    permit tcp any any eq bgp reflect tcptraffic (8 matches) sequence 10
    permit tcp any any eq telnet reflect tcptraffic (15 matches) sequence 20
    permit udp any any reflect udptraffic sequence 30

IPv6 access list tcptraffic (reflexive) (per-user)
    permit tcp host 2001:0DB8:1::1 eq bgp host 2001:0DB8:1::2 eq 11000 timeout 300 (time 
        left 243) sequence 1
    permit tcp host 2001:0DB8:1::1 eq telnet host 2001:0DB8:1::2 eq 11001 timeout 300 
        (time left 296) sequence 2

IPv6 access list outbound
    evaluate udptraffic
    evaluate tcptraffic

The following sample output shows IPv6 access list information for use with IPSec:

Router#  show ipv6 access-list
IPv6 access list Tunnel0-head-0-ACL (crypto)
     permit ipv6 any any (34 matches) sequence 1

Table 112 describes the significant fields shown in the display.

Table 112 show ipv6 dhcp binding Field Descriptions 

Field
Description

Client

Address of a specified client.

DUID

DHCP unique identifier (DUID).

Virtual-Access2.1

First virtual client. When an IPv6 DHCP client requests two prefixes with the same DUID but a different identity association for prefix delegation (IAPD ) on two different interfaces, these prefixes are considered to be for two different clients, and interface information is maintained for both.

Username : client_1

The username associated with the binding.

IA PD

Collection of prefixes assigned to a client.

IA ID

Identifier for this IAPD.

Prefix

Prefixes delegated to the indicated IAPD on the specified client.

preferred lifetime, valid lifetime

The preferred lifetime and valid lifetime settings, in seconds, for the specified client.

Expires at

Date and time at which the valid lifetime expires.

Virtual-Access2.2

Second virtual client. When an IPv6 DHCP client requests two prefixes with the same DUID but different IAIDs on two different interfaces, these prefixes are considered to be for two different clients, and interface information is maintained for both.


When the DHCPv6 pool on the Cisco IOS DHCPv6 server is configured to obtain prefixes for delegation from an authentication, authorization, and accounting (AAA) server, it sends the PPP username from the incoming PPP session to the AAA server for obtaining the prefixes. The PPP username is associated with the binding is displayed in output from the show ipv6 dhcp binding command. If there is no PPP username associated with the binding, this field value is displayed as "unassigned."

The following example shows that the PPP username associated with the binding is "client_1":

Router# show ipv6 dhcp binding

Client: FE80::2AA:FF:FEBB:CC 
  DUID: 0003000100AA00BB00CC 
  Username : client_1
  Interface : Virtual-Access2
  IA PD: IA ID 0x00130001, T1 75, T2 135
    Prefix: 2001:0DB8:1:3::/80
            preferred lifetime 150, valid lifetime 300
            expires at Aug 07 2008 05:19 AM (225 seconds)

The following example shows that the PPP username associated with the binding is unassigned:

Router# show ipv6 dhcp binding 

Client: FE80::2AA:FF:FEBB:CC 
  DUID: 0003000100AA00BB00CC 
  Username : unassigned 
  Interface : Virtual-Access2 
  IA PD: IA ID 0x00130001, T1 150, T2 240 
    Prefix: 2001:0DB8:1:1::/80 
            preferred lifetime 300, valid lifetime 300 
            expires at Aug 11 2008 06:23 AM (233 seconds)

15.1(2)S

This command was modified. The vrf vrf-name keyword and argument were added.

Cisco IOS XE Release 3.3S

This command was modified. The vrf vrf-name keyword and argument were added.


Usage Guidelines

When you configure the DHCPv6 server to detect conflicts, it uses ping. The client uses neighbor discovery to detect clients and reports to the server through a DECLINE message. If an address conflict is detected, the address is removed from the pool, and the address is not assigned until the administrator removes the address from the conflict list.

Examples

The following is a sample output from the show ipv6 dhcp conflict command. This command shows the pool and prefix values for DHCP conflicts.:

Router# show ipv6 dhcp conflict

Pool 350, prefix 2001:0DB8:1005::/48
