show bgp ipv6 neighbors

To display information about IPv6 Border Gateway Protocol (BGP) connections to neighbors, use the show bgp ipv6 neighbors command in user EXEC or privileged EXEC mode.

show bgp ipv6 {unicast | multicast} neighbors [ipv6-address] [received-routes | routes | flap-statistics | advertised-routes | paths regular-expression | dampened-routes]

Syntax Description

unicast

Specifies IPv6 unicast address prefixes.

multicast

Specifies IPv6 multicast address prefixes.

ipv6-address

(Optional) Address of the IPv6 BGP-speaking neighbor. If you omit this argument, all IPv6 neighbors are displayed.

This argument must be in the form documented in RFC 2373 where the address is specified in hexadecimal using 16-bit values between colons.

received-routes

(Optional) Displays all received routes (both accepted and rejected) from the specified neighbor.

routes

(Optional) Displays all routes received and accepted. This is a subset of the output from the received-routes keyword.

flap-statistics

(Optional) Displays flap statistics for the routes learned from the neighbor.

advertised-routes

(Optional) Displays all the routes the networking device advertised to the neighbor.

paths regular-expression

(Optional) Regular expression used to match the paths received.

Usage Guidelines

The show bgp ipv6 unicast neighbors and show bgp ipv6 multicast neighbors commands provide output similar to the show ip bgp neighbors command, except they are IPv6-specific.

The unicast keyword is available in Cisco IOS Release 12.3(2)T and later releases. It is not available in releases prior to 12.3(2)T. Use of the unicast keyword is mandatory starting with Cisco IOS Release 12.3(2)T.

The multicast keyword is available in Cisco IOS Release 12.0(26)S and later releases. It is not available in releases prior to 12.0(26)S. Use of either the unicast or multicast keyword is mandatory starting with Cisco IOS Release 12.0(26)S.

Examples

The following is sample output from the show bgp ipv6 neighbors command:


Note The output is the same whether or not the unicast or multicast keyword is used. The unicast keyword is available in Cisco IOS Release 12.3(2)T and Cisco IOS Release 12.0(26)S and later releases, and the multicast keyword is available only in Cisco IOS Release 12.0(26)S and later releases.

Usage Guidelines

Use this command to display the contents of the active voice call table. This command displays information about call times, dial peers, connections, and quality of service, and other status and statistical information for voice calls currently connected through the router.

Before you can query the echo state, you need to know the hexadecimal ID. To find the hexadecimal ID, enter the show call active voice brief command or use the show voice call status command.

When the extended EC is present, the show call active voice command displays the contents of the Ditech EC_CHAN_CTRL structure. Table 132 contains names and descriptions of the fields in the EC_CHAN_CTRL structure. Table 132 also provides a listing of the information types associated with this command.

Table 132 EC_CHAN_CTRL Field Descriptions 

Symbol
Field
Description

BYP0

Channel bypass

1 = Transparent bypass; EC is disabled.

0 = Cancel; EC is enabled.

TAIL3

Max tail

0 = 24 milliseconds.

1 = 32 milliseconds.

2 = 48 milliseconds.

3 = 64 milliseconds.

Note This field should be set just greater than the anticipated worst round-trip tail delay.

REC3

Residual echo control

0 = Cancel only; echo is the result of linear processing; no nonlinear processing is applied.

1 = Suppress residual; residual echo is zeroed; simple nonlinear processing is applied (you might experience "dead air" when talking).

2 = Reserved.

3 = Generate comfort noise (default).

FRZ0

h-register hold

1 = Freezes h-register; used for testing.

HZ0

h-register clear

Sending the channel command with this bit set clears the h-register.

TD3

Modem tone disable

0 = Ignore 2100 Hz modem answer tone.

1 = G.164 mode (bypass canceller if 2100 Hz tone).

2 = R.

3 = G.165 mode (bypass canceller for phase reversing tone only).

ERL0

Echo return loss

0 = 6 decibel (dB).

1 = 3 dB.

2 = 0 dB.

3 = R. Worst echo return loss (ERL) situation in which canceller still works.

HLC1

High level compensation

0 = No attenuation.

1 = 6 dB if clipped. On loud circuits, the received direction can be attenuated 6 dB if clipping is observed.

R0

Reserved

Must be set to 0 to ensure compatibility with future releases.


Use the show call active voice redirect tbct command to monitor any active calls that implement RTPvt or TBCT.

When a call is no longer active, its record is stored. You can display the record by using the show call history voice command.

The following is an example of the show call active voice command using the echo-canceller keyword. The number 9 represents the hexadecimal ID of an active voice call.

Router# show call active voice echo-canceller 9

ACOM=-65  ERL=45
Echo canceller control words=6C 0
Bypass=OFF  Tail=64  Residual ecan=Comfort noise
Freeze=OFF  Modem tone disable=Ignore 2100Hz tone
Worst ERL=6  High level compensation=OFF
Max amplitude reflector (in msec)=5
Ecan version = 8180

The following is sample output from the show call active voice echo-canceller command for a call with a hexadecimal ID of 10:

Router# show call active voice echo-canceller 10 

ACOM=-15  ERL=7 
Echo canceller control words=6C 0 
Bypass=OFF  Tail=64  Residual ecan=Comfort noise 
Freeze=OFF  Modem tone disable=Ignore 2100Hz tone 
Worst ERL=6  High level compensation=OFF 
Max amplitude reflector (in msec)=64 

The call ID number (which is 10 in the preceding example) changes with every new active call. When an active call is up, you must enter the show call active voice brief command to obtain the call ID number. The call ID must be converted to hexadecimal value if you want to use the show call active voice echo-canceller x command (x = call ID converted to hexadecimal value).

Table 135 shows call ID examples converted to hexadecimal values (generally incremented by 2):

Alternatively, you can use the show voice call status command to obtain the call ID. The call ID output is already in hexadecimal values form when you use this command:

Router# show voice call status

Usage Guidelines

This command displays a call-history table that contains a list of fax calls connected through the router in descending time order. The maximum number of calls contained in the table can be set to a number from 0 to 500 using the dial-control-mib command in global configuration mode. The default maximum number of table entries is 50. Each call record is aged out of the table after a configurable number of minutes has elapsed, also specified by the dial-control-mib command. The default timer value is 15 minutes.

You can display subsets of the call history table by using specific keywords. To display the last calls connected through this router, use the keyword last, and define the number of calls to be displayed with the number argument.

To display a truncated version of the call history table, use the brief keyword.

This command applies to both on-ramp and off-ramp store-and-forward fax functions.

Usage Guidelines

This command displays a call-history table that contains a list of voice calls connected through the router in descending time order. The maximum number of calls contained in the table can be set to a number from 0 to 500 using the dial-control-mib command in global configuration mode. The default maximum number of table entries is 50. Each call record is aged out of the table after a configurable number of minutes has elapsed. The timer value is also specified by the dial-control-mib command. The default timer value is 15 minutes.

You can display subsets of the call history table by using specific keywords. To display the last calls connected through this router, use the last keyword, and define the number of calls to be displayed with the number argument.

To display a truncated version of the call history table, use the brief keyword.

Use the show call active voice redirect command to review records for calls that implemented RTPvt or TBCT.

When a call is active, you can display its statistics by using the show call active voice command.

State of the ES, IS, or M-ISIS.

    Init

System is an IS and is waiting for an IS-IS hello message. IS-IS regards the neighbor as not adjacent.

    Up

Believes the ES or IS is reachable.

Holdtime

Number of seconds before this adjacency entry times out.

Type

The adjacency type. Possible values are as follows:

ES—End-system adjacency either discovered via the ES-IS protocol or statically configured.

IS—Router adjacency either discovered via the ES-IS protocol or statically configured.

M-ISIS—Router adjacency discovered via the multitopology IS-IS protocol.

L1—Router adjacency for Level 1 routing only.

This command was integrated into Cisco IOS Release 12.2(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.

Usage Guidelines

The software clock keeps an "authoritative" flag that indicates whether the time is authoritative (believed to be accurate). If the software clock has been set by a timing source (for example, via NTP), the flag is set. If the time is not authoritative, it will be used only for display purposes. Until the clock is authoritative and the "authoritative" flag is set, the flag prevents peers from synchronizing to the software clock.

The symbol that precedes the show clock display indicates the following:

Symbol
Description
Example

*

Time is not authoritative: the software clock is not in sync or has never been set.

*15:29:03.158 UTC Tue Feb 25 2003:

(blank)

Time is authoritative: the software clock is in sync or has just been set manually

15:29:03.158 UTC Tue Feb 25 2003:

.

Time is authoritative, but NTP is not synchronized: the software clock was in sync, but has since lost contact with all configured NTP servers

.15:29:03.158 UTC Tue Feb 25 2003:


These symbols are also used in NTP-based timestamping, such as for syslog (SEM) messages.


Note In general, NTP synchronization takes approximately 15 to 20 minutes.


Examples

The following sample output shows that the current clock is authoritative and that the time source is NTP:

Router> show clock detail

15:29:03.158 PST Tue Feb 25 2003
Time source is NTP

The following example shows the current clock is authoritative, but NTP is not yet synchronized:

Router> show clock

.16:42:35.597 UTC Tue Feb 25 2003

Examples

The following output example shows information about the peer named "This-is-another-peer-at-10-1-1-3":

Router# show crypto isakmp peers

Peer: 10.1.1.3 Port: 500
