Mode

Exec > Global Configuration > Context Configuration > IPv6 ACL Configuration

configure > context context_name > ipv6 access-list ipv6_acl_name

Entering the above command sequence results in the following prompt: 

[context_name]host_name(config-ipv6-acl)#

Syntax

{ deny | permit } [ log ] source_address source_wildcard 
after { deny | permit } [ log ] source_address source_wildcard 
before { deny | permit } [ log ] source_address source_wildcard 
no { deny | permit } [ log ] source_address source_wildcard

after

Indicates all rules defined subsequent to this command are to be inserted after the command identified by the exact options listed.

This moves the insertion point to be immediately after the rule which matches the exact options specified such that new rules will be added, in order, after the matching rule.


Important

If the options specified do not exactly match an existing rule, the insertion point does not change.

before

Indicates all rules defined subsequent to this command are to be inserted before the command identified by the exact options listed.

This moves the insertion point to be immediately before the rule which matches the exact options specified such that new rules will be added, in order, before the matching rule.


Important

If the options specified do not exactly match an existing rule, the insertion point does not change

no

Removes the rule which exactly matches the options specified.

deny | permit

Specifies the rule is either block (deny) or an allow (permit) filter.

  • deny : Indicates the rule, when matched, drops the corresponding packets.

  • permit : Indicates the rule, when matched, allows the corresponding packets.

log

Default: packets are not logged.

Indicates all packets which match the filter are to be logged.

source_address

The IP address(es) form which the packet originated.

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.

source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

  • Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.

  • One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.


Important

The mask must contain a contiguous set of one-bits from the least significant bit (LSB).

Usage Guidelines

Define a rule when any packet from the IP addresses which fall into the group of addresses matching the IP address masking. This allows the reduction of filtering rules as it does not require a rule for each source and destination pair.


Important

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.

Example

The following command defines two rules with the second logging filtered packets: 
permit 2001:4A2B::1f3F  
deny log 2001:4A2B::1f3F
The following sets the insertion point to before the first rule defined above: 
before permit 2001:4A2B::1f3F
The following command sets the insertion point after the second rule defined above: 
after deny log 2001:4A2B::1f3F
The following deletes the first rule defined above: 
no permit 2001:4A2B::1f3F

deny/permit (any)

Used to filter subscriber sessions based on any packet received. This command is also used to set the access control list insertion point.

Usage Guidelines

Define a catch all rule to place at the end of the list of rules.


Important

It is suggested that any rule which is added to be a catch all should also have the log option specified. The logged packets may be used to determine if the current list of rules is adequate or needs modification to ensure proper security. The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.

source_address

Filters by the IP address(es) from which the packet originated. This option filters all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.

source_wildcard

Filters packets for a group of addresses specified in conjunction with the source_address option.

The mask must be entered as a complement:

Important

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide. Also note that "redirect" rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.

Example

The following command defines a rule that redirects packets to the context with the context ID of 23 , and UDP packets coming from any host are matched: 
redirect context 23 udp any
The following sets the insertion point to before the rule defined above: 
before redirect context 23 udp any
The following command sets the insertion point after the rule defined above: 
after redirect context 23 udp any
The following deletes the rule defined above: 
no redirect context 23 udp any

downlink

Apply this rule definition only to packets in the downlink (from the Mobile Node) direction.

log

Default: packets are not logged.

Indicates all packets which match the redirect are to be logged.

any

Indicates all packets will match the redirect regardless of source and/or destination.

Usage Guidelines

Define a catch all rule definition to place at the end of the list of rule definitions to provide explicit handling of rule definitions which do not fit any other criteria.


Important

It is suggested that any rule definition which is added to be a catch all should also have the log option specified. The logged packets may be used to determine if the current list of rule definitions is adequate or needs modification to ensure proper security.


Important

A maximum of 16 rule definitions can be configured per ACL.


Important

Also note that "redirect" rule definitions are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.

Example

The following command defines a rule definition that redirects packets to the CSS service with the name css-svc1 and any source IP: 
redirect css service css-svc1 downlink any
The following sets the insertion point to before the first rule definition above:

The name of the Content Service steering (CSS) service to which packets are to be redirected. At the executive mode prompt, use the show css service all command to display the names of all configured CSS services.

svc_name must be an alphanumeric string of 1 through 15 characters.

uplink

Apply this rule definition only to packets in the uplink (to the Mobile Node) direction.

log

Default: packets are not logged.

Indicates all packets which match the redirect are to be logged.

any

Indicates all packets will match the redirect regardless of source and/or destination.

Usage Guidelines

Define a catch all rule definition to place at the end of the list of rule definitions to provide explicit handling of rule definitions which do not fit any other criteria.


Important

It is suggested that any rule definition which is added to be a catch all should also have the log option specified. The logged packets may be used to determine if the current list of rule definitions is adequate or needs modification to ensure proper security.


Important

A maximum of 16 rule definitions can be configured per ACL.


Important

Also note that "redirect" rule definitions are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.

Example

The following command defines a rule definition that redirects packets to the charging service with the name css-svc1 and any source IP: 
redirect css service css-svc1 uplink any
The following sets the insertion point to before the first rule definition above:

interface interface_name

The name of the logical interface to which the packets should be redirected. interface_name must be an alpha and/or numeric string from 1 to 79 characters.

log

Default: packets are not logged.

Indicates all packets which match the redirect are to be logged.

source_address

The IP address(es) form which the packet originated.

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.

source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

  • Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.

  • One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.


Important

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.

Usage Guidelines

Define a rule when any packet from the IP addresses which fall into the group of addresses matching the IP address masking. This allows the reduction of redirect rules as it does not require a rule for each source and destination pair.


Important

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide. Also note that "redirect" rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.

Example

The following command defines a rule that redirects packets to the next hop host at 192.168.10.4 , the context with the context ID of 23 and the source IP and wildcard of 198.162.22.0 and 0.0.0.31 : 
redirect nexthop 192.168.10.4 context 23 198.162.22.0 0.0.0.31
The following sets the insertion point to before the first rule defined above:

Indicates all packets will match the redirect regardless of source and/or destination.

Usage Guidelines

Define a catch all rule to place at the end of the list of rules to provide explicit handling of rules which do not fit any other criteria.


Important

It is suggested that any rule which is added to be a catch all should also have the log option specified. The logged packets may be used to determine if the current list of rules is adequate or needs modification to ensure proper security. The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide. Also note that "redirect" rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.

log

Default: packets are not logged.

Indicates all packets which match the redirect are to be logged.

source_address

The IP address(es) form which the packet originated.

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.

source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

  • Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.

  • One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.


Important

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.

This option is used to filter all packets to a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this parameter. The range can then be configured using the dest_wildcard parameter.

dest_wildcard

This option is used in conjunction with the dest_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

  • Zero-bits in this parameter mean that the corresponding bits configured for the dest_address parameter must be identical.

  • One-bits in this parameter mean that the corresponding bits configured for the dest_address parameter must be ignored.


Important

The mask must contain a contiguous set of one-bits from the least significant bit (LSB).

icmp_type

Specifies that all ICMP packets of a particular type are to be filtered. The type can be an integer value from 0 through 255.

icmp_code

Specifies that all ICMP packets of a particular code are to be filtered. The type can be an integer value from 0 through 255.

Usage Guidelines

Define a rule to block ICMP packets which can be used for address resolution and possible be a security risk.

The IP redirecting allows flexible controls for pairs of individual hosts or groups by IP masking which allows the redirecting of entire subnets if necessary.


Important

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide. Also note that "redirect" rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.

Example

The following command defines a rule that redirects packets to the next hop host at fe80::c0a8:a04 , the context with the context ID of 23 , and ICMP packets coming from the host with the IP address 2002::c6a2:64195 : 
redirect nexthop fe80::c0a8:a04 context 23 icmp host 2002::c6a2:6419
