Access List Debug Commands on Cisco IOS XR Software

---

This chapter describes the commands used to debug access list problems.

debug ipv4 access-list

To enable IPv4 access list debugging, use the debug ipv4 access-list command in EXEC mode. To disable the debugging of IPv4 access lists, use the no form of this command.

debug ipv4 access-list [all | classification | dispatch | events | manager | parser-cache {errors | events} | timers]

no debug ipv4 access-list [all | classification | dispatch | events | manager | parser-cache {errors | events} | timers]

Syntax Description

all	(Optional) Displays all IPv4 access list debug information.
classification	(Optional) Displays classification application program interface (API) debug information.
dispatch	(Optional) Displays dispatcher process event debug information.
events	(Optional) Displays IPv4 access list event debug information.
manager	(Optional) Displays manager process event debug information.
parser-cache	(Optional) Displays IPv4 parser-cache debug information.
errors	Displays IPv4 parser-cache error debug information.
events	Displays IPv4 parser-cache event debug information.
timers	(Optional) Displays timer event debug information.

Command History

Release	Modification
Release 2.0	This command was introduced on the Cisco CRS-1.
Release 3.0	No modification.
Release 3.2	This command was supported on the Cisco XR 12000 Series Router.
Release 3.3.0	No modification.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

Debugging output is assigned high priority in the CPU process and, therefore, can affect system performance. For more information about the impact on system performance when using debug commands, refer to Using Debug Commands on Cisco IOS XR Software.

Task ID	Operations
ipv4	read
acl	read

Examples

The following example shows how to enable IPv4 access list debugging:

RP/0/RP0/CPU0:router# debug ipv4 access-list all 

debug ipv6 access-list

To enable IPv6 access list debugging, use the debug ipv6 access-list command in EXEC mode. To disable the debugging of IPv6 access lists, use the no form of this command.

debug ipv6 access-list {cfg-agent | daemon | dll} {all | ens | errors | info | match | trace}

no debug ipv6 access-list {cfg-agent | daemon | dll} {all | ens | errors | info | match | trace}

Syntax Description

cfg-agent	Displays IPv6 access control list (ACL) configuration agent debug information.
daemon	Displays IPv6 ACL daemon debug information.
dll	Displays IPv6 ACL dynamic link library (DLL) debug information.
all	Displays all IPv6 ACL debug information related to the selected cfg-agent, daemon, or dll keyword.
ens	Displays Event Notification Service (ENS) and Name Registration Service (NRS) related daemon operations debug information. This option is available when the daemon keyword is selected.
errors	Displays IPv6 ACL error debug information related to the selected cfg-agent, daemon, or dll keyword.
info	Displays debug information related to the selected cfg-agent, daemon, or dll keyword.
match	Displays IPv6 ACL DLL match debug information. This option is available when the dll keyword is selected.
trace	Displays trace of function call debug information related to the selected cfg-agent or daemon keyword.
