Usage Guidelines

The show ipv6 route command provides output similar to the show ip route command, except that the information is IPv6-specific.

When the ipv6-address or ipv6-prefix/prefix-length argument is specified, a longest match lookup is performed from the routing table and only route information for that address or network is displayed. When a routing protocol is specified, only routes for that protocol are displayed. When the connected, local, mobile, or static keyword is specified, only that type of route is displayed. When the interface-type interface-number arguments are specified, only the specified interface-specific routes are displayed.

Table 265 describes the significant fields shown in the previous two displays.

Table 265 show ipv6 routers Field Descriptions
Field	Description
Hops	The configured hop limit value for the router advertisement.
Lifetime	The configured Router Lifetime value for the router advertisement. A value of 0 indicates that the router is not a default router. A value other than 0 indicates that the router is a default router.
AddrFlag	If the value is 0, the router advertisement received from the router indicates that addresses are not configured using the stateful autoconfiguration mechanism. If the value is 1, the addresses are configured using this mechanism.
OtherFlag	If the value is 0, the router advertisement received from the router indicates that information other than addresses is not obtained using the stateful autoconfiguration mechanism. If the value is 1, other information is obtained using this mechanism. (The value of OtherFlag can be 1 only if the value of AddrFlag is 1.)
MTU	The maximum transmission unit (MTU).
HomeAgentFlag=1	The value can be either 0 or 1. A value of 1 indicates that the router from which the RouterAdvertisement was received is functioning as a Mobile IPv6 home agent on this link, and a value of 0 indicates it is not functioning as a Mobile IPv6 home agent on this link.
Preference=High	The default router preference. The value can be high, medium, or low.
Retransmit time	The configured RetransTimer value. The time value to be used on this link for neighbor solicitation transmissions, which are used in address resolution and neighbor unreachability detection. A value of 0 means the time value is not specified by the advertising router.
Prefix	A prefix advertised by the router. Also indicates if onlink or autoconfig bits were set in the router advertisement message.
Valid lifetime	The length of time (in seconds) relative to the time the advertisement is sent that the prefix is valid for the purpose of onlink determination. A value of -1 (all ones, 0xffffffff) represents infinity.
preferred lifetime	The length of time (in seconds) relative to the time the advertisements is sent that addresses generated from the prefix via address autoconfiguration remain valid. A value of -1 (all ones, 0xffffffff) represents infinity.

When the interface-type and interface-number arguments are specified, router advertisement details about that specific interface are displayed. The following is sample output from the show ipv6 routers command when entered with an interface type and number:

Router# show ipv6 routers tunnel 5

Router FE80::83B3:60A4 on Tunnel5, last update 5 min

  Hops 0, Lifetime 6000 sec, AddrFlag=0, OtherFlag=0

  Reachable time 0 msec, Retransmit time 0 msec

  Prefix 3FFE:C00:8007::800:207C:4E37/96 autoconfig

    Valid lifetime -1, preferred lifetime -1

Entering the conflicts keyword with the show ipv6 routers command displays information for routers that are advertising parameters different from the parameters configured for the interface on which the advertisements are being received, as the following sample output shows:

Router# show ipv6 routers conflicts

Router FE80::203:FDFF:FE34:7039 on Ethernet1, last update 1 min, CONFLICT

   Hops 64, Lifetime 1800 sec, AddrFlag=0, OtherFlag=0

Usage Guidelines

The show ipv6 rpf command displays how IPv6 multicast routing performs RPF. Because the router can find RPF information from multiple routing tables (for example, unicast Routing Information Base [RIB], multiprotocol Border Gateway Protocol [BGP] routing table, or static mroutes), the show ipv6 rpf command displays the source from which the information is retrieved.

Examples

The following example displays RPF information for the unicast host with the IPv6 address of 2001::1:1:2:

Router# show ipv6 rpf 2001::1:1:2

RPF information for 2001::1:1:2

  RPF interface:Ethernet3/2

Table 275 describes the significant fields shown in the display.

Table 275 show isis database Field Descriptions
Field	Description
Tag tagFirst	Tag name that identifies an IS-IS instance.
LSPID	The LSP identifier. The first six octets form the system ID of the router that originated the LSP. The next octet is the pseudonode ID. When this byte is nonzero, the LSP describes links from the system. When it is zero, the LSP is a so-called nonpseudonode LSP. This mechanism is similar to a router link-state advertisement (LSA) in the Open Shortest Path First (OSPF) protocol. The LSP will describe the state of the originating router. For each LAN, the designated router for that LAN will create and flood a pseudonode LSP, describing all systems attached to that LAN. The last octet is the LSP number. If there is more data than can fit in a single LSP, the LSP will be divided into multiple LSP fragments. Each fragment will have a different LSP number. An asterisk (*) indicates that the LSP was originated by the system on which this command is issued.
LSP Seq Num	Sequence number for the LSP that allows other systems to determine if they have received the latest information from the source.
LSP Checksum	Checksum of the entire LSP packet.
LSP Holdtime	Amount of time the LSP remains valid (in seconds). An LSP hold time of zero indicates that this LSP was purged and is being removed from the link-state database (LSDB) of all routers. The value indicates how long the purged LSP will stay in the LSDB before being completely removed.
ATT	The Attach bit. This bit indicates that the router is also a Level 2 router, and it can reach other areas. Level 1-only routers and Level 1-2 routers that have lost connection to other Level 2 routers will use the Attach bit to find the closest Level 2 router. They will point a default route to the closest Level 2 router.
P	The P bit. Detects if the intermediate systems is area partition repair-capable. Cisco and other vendors do not support area partition repair.
OL	The Overload bit. Determines if the IS is congested. If the Overload bit is set, other routers will not use this system as a transit router when calculating routers. Only packets for destinations directly connected to the overloaded router will be sent to this router.

The following is sample output from the show isis database detail command:

As the output shows, in addition to the information displayed with the show isis database command, the show isis database detail command displays the contents of each LSP.

Table 276 describes the significant fields shown in the display.

Table 276 show isis database detail Field Descriptions
Field	Description
Area Address	Reachable area addresses from the router. For Level 1 LSPs, these are the area addresses configured manually on the originating router. For Level 2 LSPs, these are all the area addresses for the area to which this router belongs.
Metric	IS-IS metric for the cost of the adjacency between the originating router and the advertised neighbor, or the metric of the cost to get from the advertising router to the advertised destination (which can be an IP address, an end system [ES], or a CLNS prefix).
Topology	States the topology supported (for example, IPv4, IPv6).
IPv6 Address	The IPv6 address.
MT-IPv6	Advertised using multitopology Type, Length, and Value objects (TLVs).

The following is additional sample output from the show isis database detail command. This LSP is a Level 2 LSP. The area address 39.0001 is the address of the area in which the router resides.

Table 278 describes the significant fields shown in the display.

Table 278 show isis spf-log Field Descriptions
Field	Description
When	How long ago (in hours: minutes: seconds) a full SPF calculation occurred. The last 20 occurrences are logged.
Duration	Number of milliseconds required to complete this SPF run. Elapsed time is wall clock time, not CPU time.
Nodes	Number of routers and pseudonodes (LANs) that make up the topology calculated in this SPF run.
Count	Number of events that triggered this SPF run. When there is a topology change, often multiple link-state packets (LSPs) are received in a short time. A router waits 5 seconds before running a full SPF run, so it can include all new information. This count denotes the number of events (such as receiving new LSPs) that occurred while the router was waiting its 5 seconds before running full SPF.
Last trigger LSP	Whenever a full SPF calculation is triggered by the arrival of a new LSP, the router stores the LSP ID. The LSP ID can provide a clue as to the source of routing instability in an area. If multiple LSPs are causing an SPF run, only the LSP ID of the last received LSP is remembered.
Triggers	A list of all reasons that triggered a full SPF calculation. For a list of possible triggers, see Table 279.

Table 279 lists possible triggers of a full SPF calculation.

Table 279 Possible Triggers of Full SPF Calculation
Trigger	Description
ADMINDIST	Another administrative distance was configured for the IS-IS process on this router.
AREASET	Set of learned area addresses in this area changed.
ATTACHFLAG	This router is now attached to the Level 2 backbone or it has just lost contact to the Level 2 backbone.
BACKUPOVFL	An IP prefix disappeared. The router knows there is another way to reach that prefix but has not stored that backup route. The only way to find the alternative route is through a full SPF run.
DBCHANGED	A clear isis * command was issued on this router.
IPBACKUP	An IP route disappeared, which was not learned via IS-IS, but via another protocol with better administrative distance. IS-IS will run a full SPF to install an IS-IS route for the disappeared IP prefix.
IPQUERY	A clear ip route command was issued on this router.
LSPEXPIRED	Some LSP in the link-state database (LSDB) has expired.
LSPHEADER	ATT/P/OL bits or is-type in an LSP header changed.
NEWADJ	This router has created a new adjacency to another router.
NEWAREA	A new area (via network entity title [NET]) was configured on this router.
NEWLEVEL	A new level (via is-type) was configured on this router.
NEWLSP	A new router or pseudonode appeared in the topology.
NEWMETRIC	A new metric was configured on an interface of this router.
NEWSYSID	A new system ID (via NET) was configured on this router.
PERIODIC	Typically, every 15 minutes a router runs a periodic full SPF calculation.
RTCLEARED	A clear clns route command was issued on this router.
TLVCODE	TLV code mismatch, indicating that different type length values (TLVs) are included in the newest version of an LSP.
TLVCONTENT	TLV contents changed. This normally indicates that an adjacency somewhere in the area has come up or gone down. The "Last trigger LSP" column indicates where the instability may have occurred.

12.2(33)SRA	This command was integrated into Cisco IOS Release 12.2(33)SRA.
12.2(33)SRB1	This command was integrated into Cisco IOS Release 12.2(33)SRB1.

Usage Guidelines

This command is not supported on Cisco 7600 series routers that are configured with a Supervisor Engine 2.

You can enter this command on the supervisor engine and Multilayer Switching (MLS)-hardware Layer 3-switching module consoles only. Enter the remote login command to enter a session into the supervisor engine and distributed forwarding card (DFC)-equipped module to enter the commands.

When entering the ip-address/mask argument, use this format, X:X:X:X::X/mask, where valid values for mask are from 0 to 128.

Up to 64 IPv6 prefixes are supported.

You must enter the L4-src-port and L4-dst-port arguments when the load-sharing mode is set to full, for example, when Layer 4 ports are included in the load-sharing hashing algorithm.

12.4(20)T	This command was integrated into Cisco IOS Release 12.4(20)T.

Usage Guidelines

Use the show monitor event-trace cef ipv6 command to display trace message information for Cisco Express Forwarding IPv6 events.

The trace function is not locked while information is displayed to the console. This means that new trace messages can accumulate in memory. If entries accumulate faster than they can be displayed, some messages can be lost. If this happens, the show monitor event-trace cef ipv6 command generates a message indicating that some messages might be lost; however, messages continue to be displayed on the console. If the number of lost messages is excessive, the show monitor event-trace cef ipv6 command stops displaying messages.

Examples

The following is a sample of the show monitor event-trace cef ipv6 all command:

Router# show monitor event-trace cef ipv6 all

*Aug 22 20:14:59.075:  [Default] *::*/*                Allocated FIB table

                      [OK]

*Aug 22 20:14:59.075:  [Default] *::*/*'00             Add source Default table

                      [OK]

*Aug 22 20:14:59.075:  [Default] ::/0'00               FIB add src DRH (ins)

                      [OK]

*Aug 22 20:14:59.075:  [Default] *::*/*'00             New FIB table

                      [OK]

Table 286 describes the significant fields shown in the displays.

Table 286 show mpls forwarding-table Field Descriptions
Field	Description
Local label	Label assigned by this router.
Outgoing Label or VC Note This field is not supported on the Cisco 10000 series routers.	Label assigned by the next hop or the virtual path identifier (VPI)/virtual channel identifier (VCI) used to get to next hop. The entries in this column are the following: •[T]—Forwarding is through an LSP tunnel. •No Label—There is no label for the destination from the next hop or label switching is not enabled on the outgoing interface. •Pop Label—The next hop advertised an implicit NULL label for the destination and the router removed the top label. •Aggregate—There are several prefixes for one local label. This entry is used when IPv6 is configured on edge routers to transport IPv6 traffic over an IPv4 MPLS network.
Prefix or Tunnel Id	Address or tunnel to which packets with this label are sent. Note If IPv6 is configured on edge routers to transport IPv6 traffic over an IPv4 MPLS network, "IPv6" is displayed here. •[V]—The corresponding prefix is in a VRF.
Bytes label switched	Number of bytes switched with this incoming label. This includes the outgoing label and Layer 2 header.
Outgoing interface	Interface through which packets with this label are sent.
Next Hop	IP address of the neighbor that assigned the outgoing label.
Bundle adjacency exp(vcd)	Bundle adjacency information. Includes the MPLS EXP value and the corresponding VCD.
MAC/Encaps	Length in bytes of the Layer 2 header and length in bytes of the packet encapsulation, including the Layer 2 header and label header.
MTU	MTU of the labeled packet.
label Stack	All the outgoing labels. If the outgoing interface is transmission convergence (TC)-ATM, the VCD is also shown. Note TC-ATM is not supported on Cisco 10000 series routers.
00010000AAAA030000008847 00013000	The actual encapsulation in hexadecimal form. A space is shown between Layer 2 and the label header.

Field	Description
Local label	Label assigned by this router.
Outgoing label or VC	Label assigned by the next hop or VPI/VCI used to get to the next hop. The entries in this column are the following: •[T]—Forwarding is through an LSP tunnel. •No label—There is no label for the destination from the next hop or that label switching is not enabled on the outgoing interface. •Pop label—The next hop advertised an implicit NULL label for the destination and that this router popped the top label. •Aggregate—There are several prefixes for one local label. This entry is used when IPv6 is configured on edge routers to transport IPv6 traffic over an IPv4 MPLS network. •0—The explicit null label value = 0.
Prefix or Tunnel Id	Address or tunnel to which packets with this label are sent. Note If IPv6 is configured on edge routers to transport IPv6 traffic over an IPv4 MPLS network, IPv6 is displayed here. •[V]—Means that the corresponding prefix is in a VRF.
Bytes label switched	Number of bytes switched with this incoming label. This includes the outgoing label and Layer 2 header.
Outgoing interface	Interface through which packets with this label are sent.
Next Hop	IP address of the neighbor that assigned the outgoing label.

[H]     Local label is being held down temporarily.

Table 288 describes the Local Label fields relating to the Cisco IOS Software Modularity: MPLS Layer 3 VPNs feature.

Table 288 show mpls forwarding-table Field Descriptions
Field	Description
Local Label	Label assigned by this router. •[H]—Local labels are in holddown, which means that the application that requested the labels no longer needs them and stops advertising them to its labeling peers. The label's forwarding-table entry is deleted after a short, application-specific time. If any application starts advertising a held-down label to its labeling peers, the label could come out of holddown. Note [H] is not shown if labels are held down globally. A label enters global holddown after a stateful switchover or a restart of certain processes in a Cisco IOS modularity environment. •[T]—The label is forwarded through an LSP tunnel. Note Although [T] is still a property of the outgoing interface, it is shown in the Local Label column. •[HT]—Both conditions apply.

L2VPN Inter-AS Option B: Example

The following is sample output from the show mpls forwarding-table interface command. In this example, the pseudowire identifier (that is, 4096) is displayed in the Prefix or Tunel Id column.

Field	Description
OSPFv3 statistics	Traffic statistics accumulated for all OSPFv3 processes running on the router. To ensure compatibility with the show ip traffic command, only checksum errors are displayed. Identifies the route map name.
OSPFv3 queues statistic for process ID	Queue statistics specific to Cisco IOS software.
Hello queue	Statistics for the internal Cisco IOS queue between the packet switching code (process IP Input) and the OSPFv3 hello process for all received OSPFv3 packets.
Router queue	Statistics for the internal Cisco IOS queue between the OSPFv3 hello process and the OSPFv3 router for all received OSPFv3 packets except OSPFv3 hellos.
queue size	Actual size of the queue.
queue limit	Maximum allowed size of the queue.
queue max size	Maximum recorded size of the queue.
Interface statistics	Per-interface traffic statistics for all interfaces that belong to the specific OSPFv3 process ID.
OSPFv3 packets received/sent	Number of OSPFv3 packets received and sent on the interface, sorted by packet types.
OSPFv3 header errors	Packet appears in this section if it was discarded because of an error in the header of an OSPFv3 packet. The discarded packet is counted under the appropriate discard reason.
OSPFv3 LSA errors	Packet appears in this section if it was discarded because of an error in the header of an OSPFv3 link-state advertisement (LSA). The discarded packet is counted under the appropriate discard reason.
Summary traffic statistics for process ID	Summary traffic statistics accumulated for an OSPFv3 process. Note The OSPFv3 process ID is a unique value assigned to the OSPFv3 process in the configuration. The value for the received errors is the sum of the OSPFv3 header errors that are detected by the OSPFv3 process, unlike the sum of the checksum errors that are listed in the global OSPFv3 statistics.

Usage Guidelines

You can view static and dynamic route maps with the show route-map command. For Cisco IOS Release 12.3(14)T and later 12.4 and 12.4T releases, you can display the ACL-specific information that pertains to the route map in the same display without having to execute a show route-map command to display each ACL that is associated with the route map.

Redistribution

Use the route-map global configuration command, and the match and set route-map configuration commands, to define the conditions for redistributing routes from one routing protocol into another. Each route-map command has a list of match and set commands associated with it. The match commands specify the match criteria—the conditions under which redistribution is allowed for the current route-map command. The set commands specify the set actions—the particular redistribution actions to perform if the criteria enforced by the match commands are met. The no route-map command deletes the route map.

The match route-map configuration command has multiple formats. The match commands can be given in any order, and all match commands must "pass" to cause the route to be redistributed according to the set actions given with the set commands. The no forms of the match commands remove the specified match criteria.

Use route maps when you want detailed control over how routes are redistributed between routing processes. The destination routing protocol is the one you specify with the router global configuration command. The source routing protocol is the one you specify with the redistribute router configuration command. See the "Examples" section for an illustration of how route maps are configured.

When you are passing routes through a route map, a route map can have several parts. Any route that does not match at least one match clause relating to a route-map command will be ignored; that is, the route will not be advertised for outbound route maps and will not be accepted for inbound route maps. If you want to modify only some data, you must configure a second route map section with an explicit match specified.

Examples

The show route-map command will display configured route-maps, match, set, and continue clauses. The output will vary depending on which keywords are included with the command, and which software image is running in your router, as shown in the following examples:

•show route-map Command with No Keywords Specified: Example

•show route-map Command with Dynamic Route Map Specified: Example

•show route-map Command with Detailed ACL Information for Route Maps Specified: Example

Usage Guidelines

The router on which you use the show sccp command must be equipped with one or more digital T1/E1 packet voice trunk network modules (NM-HDVs) or high-density voice (HDV) transcoding/conferencing DSP farms (NM-HDV-FARMs) to provide digital signal processor (DSP) resources.

Use the show sccp ccm group command to show detailed information about all groups assigned to the Cisco Unified CallManager. The optional group-number argument can be added to select details about a specific group.

Configure the show sccp server statistics command on the Cisco Unified Border Element, IP-to-IP Gateway, or Session Border Controller where no SCCP phone is registered, to show the statistical counts on the SCCP server. The counts display queuing errors and message drops on the transcoder alone when it is on the Cisco Unified Border Element, IP-to-IP Gateway, or Session Border Controller.

When the show sccp server statistics command is used on the Cisco Unified Manager Express (CME), it is recommended for use together with the clear sccp server statistics command.

Command Modes

Privileged EXEC (#)

Command History


Release	Modification
12.2(15)T	This command was introduced.
12.4(22)T	Command output was updated to show IPv6 information and to display Resource Reservation Protocol (RSVP) quality of service (QoS) preconditions information.

Usage Guidelines

The show sip-ua calls command displays active UAC and UAS information for SIP calls on a Cisco IOS device. The output includes information about IPv6, RSVP, and media forking for each call on the device and for all media streams associated with the calls. There can be any number of media streams associated with a call, of which typically only one is active. However, a call can include up to three active media streams if the call is media-forked. Use this command when debugging multiple media streams to determine if an active call on the device is forked.

Examples

The following is sample output from the show sip-ua calls command for a forked call with four associated media streams, three of which are currently active:

Table 307 describes the significant fields shown in the display.

Table 307 show sip-ua connections Field Descriptions
Field	Description
Total active connections	Indicates all the connections that the gateway holds for various targets. Statistics are broken down within individual fields.
No. of send failures	Indicates the number of TCP or UDP messages dropped by the transport layer. Messages are dropped if there were network issues, and the connection was frequently ended.
No. of remote closures	Indicates the number of times a remote gateway ended the connection. A higher value indicates a problem with the network or that the remote gateway does not support reusing the connections (thus it is not RFC 3261-compliant). The remote closure number can also contribute to the number of send failures.
No. of conn. failures	Indicates the number of times that the transport layer was unsuccessful in establishing the connection to the remote agent. The field can also indicate that the address or port configured under the dial peer might be incorrect or that the remote gateway does not support that mode of transport.
No. of inactive conn. ageouts	Indicates the number of times that the connections were ended or timed out because of signaling inactivity. During call traffic, this number should be zero. If it is not zero, we recommend that the inactivity timer be tuned to optimize performance by using the timers command.
Max. tcp send msg queue size of 0, recorded for 0.0.0.0:0	Indicates the number of messages waiting in the queue to be sent out on the TCP connection when the congestion was at its peak. A higher queue number indicates that more messages are waiting to be sent on the network. The growth of this queue size cannot be controlled directly by the administrator.
Tuples with no matching socket entry	Any tuples for the connection entry that are marked with "" at the end of the line indicate an upper transport layer error condition; specifically, that the upper transport layer is out of sync with the lower connection layer. Cisco IOS software should automatically overcome this condition. If the error persists, execute the clear sip-ua udp connection or clear sip-ua tcp connection** command and report the problem to your support team.
Tuples with mismatched address/port entry	Any tuples for the connection entry that are marked with "++" at the end of the line indicate an upper transport layer error condition, where the socket is probably readable, but is not being used. If the error persists, execute the clear sip-ua udp connection or clear sip-ua tcp connection command and report the problem to your support team.
Remote-Agent Connections-Count	Connections to the same target address. This field indicates how many connections are established to the same host.
Remote-Port Conn-Id Conn-State WriteQ-Size	Connections to the same target address. This field indicates how many connections are established to the same host. The WriteQ-Size field is relevant only to TCP connections and is a good indicator of network congestion and if there is a need to tune the TCP parameters.

Table 309 describes the significant fields shown in the displays.

Table 309 show standby Field Descriptions
Field	Description
Ethernet - Group	Interface type and number and Hot Standby group number for the interface.
State is	State of local router; can be one of the following: •Active—Indicates the current Hot Standby router. •Standby—Indicates the router next in line to be the Hot Standby router. •Speak—Router is sending packets to claim the active or standby role. •Listen—Router is neither in the active nor standby state, but if no messages are received from the active or standby router, it will start to speak. •Init or Disabled—Router is not yet ready or able to participate in HSRP, possibly because the associated interface is not up. HSRP groups configured on other routers on the network that are learned via snooping are displayed as being in the Init state. Locally configured groups with an interface that is down or groups without a specified interface IP address appear in the Init state. For these cases, the Active addr and Standby addr fields will show "unknown." The state is listed as disabled in the fields when the standby ip command has not been specified. •Init (tracking shutdown)—HSRP groups appear in the Init state when HSRP group shutdown has been configured and a tracked object goes down.
Virtual IP address is, Secondary virtual IP addresses	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 (Address Resolution Protocol) cache entry.
Active virtual MAC address	Virtual MAC address being used by the current active router.
Local virtual MAC address	Virtual MAC address that would be used if this router became the active router. The origin of this address (displayed in parentheses) can be "default," "bia," (burned-in address) or "confgd" (configured).
Hello time, hold time	The hello time is the time between hello packets (in seconds) based on the command. The holdtime is the time (in seconds) before other routers declare the active or standby router to be down, based on the standby timers command. All routers in an HSRP group use the hello and hold- time values of the current active router. If the locally configured values are different, the variance appears in parentheses after the hello time and hold-time values.
Next hello sent in	Time in which the Cisco IOS software will send the next hello packet (in hours:minutes:seconds).
Gratuitous ARP 14 sent, next in 7.412 secs	Number of the gratuitous ARP packet HSRP has sent and the time in seconds when HSRP will send the next gratuitous ARP packet. This output appears only when HSRP sends gratuitous ARP packets.
Authentication	Authentication type configured based on the standby authentication command.
key-string	Indicates a key string is used for authentication. Configured key chains are not displayed.
timeout	Duration (in seconds) that HSRP will accept message digests based on both the old and new keys.
Preemption enabled, sync delay	Indicates whether preemption is enabled. If enabled, the minimum delay is the time a higher-priority nonactive router will wait before preempting the lower-priority active router. The sync delay is the maximum time a group will wait to synchronize with the IP redundancy clients.
Active router is	Value can be "local," "unknown," or an IP address. Address (and the expiration date of the address) of the current active Hot Standby router.
Standby router is	Value can be "local," "unknown," or an IP address. Address (and the expiration date of the address) of the "standby" router (the router that is next in line to be the Hot Standby router).
BFD enabled	Indicates that BFD peering is enabled on the router.
expires in	Time (in hours:minutes:seconds) in which the standby router will no longer be the standby router if the local router receives no hello packets from it.
Tracking	List of interfaces that are being tracked and their corresponding states. Based on the standby track command.
Group name is	The name of the HSRP group.
Follow by groups:	Indicates the client HSRP groups that have been configured to follow this HSRP group.
P	Indicates that the router is configured to preempt.

Related Commands


Command	Description
standby authentication	Configures an authentication string for the HSRP.
standby ip	Activates the HSRP.
standby mac-address	Specifies the virtual MAC address for the virtual router.
standby mac-refresh	Refreshes the MAC cache on the switch by periodically sending packets from the virtual MAC address.
standby preempt	Configures HSRP preemption and preemption delay.
standby priority	Configures Hot Standby priority of potential standby routers.
standby timers	Configures the time between hello messages and the time before other routers declare the active Hot Standby or standby router to be down.
standby track	Configures an interface so that the Hot Standby priority changes based on the availability of other interfaces.
standby use-bias	Configures HSRP to use the BIA of the interface as its virtual MAC address, instead of the preassigned MAC address (on Ethernet and FDDI) or the functional address (on Token Ring).
