Access Control List Commands (XGS)

When you attach an access list to a VLAN interface or LAG interface as well as to a physical interface that is a member of that LAG and/or VLAN interface, the priority order is:

1. VLAN interface

2. LAG interface

3. Physical interface

For example, if you attach access lists to both a LAG interface and a physical interface that is a member of that LAG, matching traffic rules are applied to the LAG interface, but not to the physical interface.

Use the no form of this command to detach an ARP access group.

Note: To attach an ARP access-group to an interface, the ingress-arp TCAM group should be enabled. See the hardware-profile filter (XGS) command for more details.

Command Syntax

arp access-group NAME in

no arp access-group NAME in

Parameters

NAME

ARP Access list name

Command Mode

Interface mode

Applicability

This command was introduced in OcNOS version 1.3.6.

Example

#configure terminal

(config)#arp access-list ARP_ACL1

(config-arp-acl)#exit

(config)#interface xe1

(config-if)#arp access-group ARP_ACL1 in

(config-if)#no arp access-group ARP_ACL1 in

arp access-list

Use this command to define a named ARP access control list (ACL) that determines whether to accept or drop an incoming ARP packet based on the sender or target IP address, sender or target MAC address, ARP type.

An ACL is made up of one or more ACL specifications.

Each packet that arrives at the device is compared to each specification in each ACL in the order that they are sequenced. The device continues to look until it has a match. If no match is found and the device reaches the end of the list, the packet is denied by default. For this reason, place the most frequently occurring specifications at the top of the list.

The device stops checking the specifications after a match occurs.

There is an implied deny specification for traffic that is not permitted. The implied specification can be updated to permit if the use-case is to deny a certain set of ARP traffic.

Use the no form of this command to remove an ACL specification

ip access-group

Use this command to attach an IP access list to an interface or terminal line to filter incoming or outgoing IP packets.

The time-range parameter is optional. If used, the access-group is tied to the timer specified.

After the access-group has been configured with the time-range, to detach the access-group from the time-range, use the no form of this command with a time-range parameter as shown in the syntax and examples below.

To delete the access-group, use the no form of this command without a time-range.

Note: An egress IP ACL is supported on physical and lag interfaces only. An egress IP ACL will match only routed traffic and not switched traffic. VLAN and inner-VLAN options in ACL rules will match incoming packet VLANs even when ACL attached at egress.

Egress TCAMs do not auto-expand beyond 256 entries if any entry includes a policer action. Therefore, the total number of configurable entries in the egress direction is limited to 256.

Command Syntax

ip access-group NAME (in|out) (time-range TR_NAME|)

no ip access-group NAME (in|out) (time-range TR_NAME|)

Parameters

NAME

Access list name.

Filter incoming packets

out

Filter outgoing packets.

TR_NAME

Time range name set with the time-range command.

Command Mode

Line mode

Interface mode

Applicability

This command was introduced before OcNOS version 1.3. The time-range parameter was added in OcNOS-SP version 5.0.

Examples

#configure terminal

(config)#ip access-list mylist

(config-ip-acl)#permit ip any any

(config-ip-acl)#exit

(config)#hardware-profile filter ingress-ipv4-ext enable

(config)#interface xe3

(config-if)#ip access-group mylist in

(config-if)#exit

(config)#interface xe3

(config-if)#no ip access-group mylist in time-range TIMER1

(config-if)#exit

(config)#line vty

(config-all-line)#no ip access-group mylist in

Usage: VLANs and LAGs

When you attach an access list to a VLAN interface or LAG interface as well as to a physical interface that is a member of that LAG and/or VLAN interface, the priority order is:

1. VLAN interface

2. LAG interface

3. Physical interface

Usage: TCAM Groups

An access-group in the egress direction uses the TCAM group used by the QoS output service policy. Therefore, actions are unpredictable when conflicting matches are configured on same interface. IP Infusion Inc. recommends to avoid such a configuration. Otherwise, you need to configure the priority (in QoS) or the sequence number (in ACL) carefully to handle such cases.

To attach an IP ACL in the ingress direction, ensure the ingress-ipv4 TCAM group is enabled. See the hardware-profile filter (XGS) commands for details.

Usage: Loopback and VTY Interfaces

You can create ACLs for loopback (inband) and VTY interfaces to protect management applications such as SSH, Telnet, NTP, SNMP, and SNMP traps. Filtering TCP, UDP, and ICMP are supported.

Note: Loopback and VTY ACLs are mutually exclusive. If you set up one, you cannot set up the other.

For an ACL for a loopback interface, you create the ACL, configure it with rules, and associate the ACL with a loopback interface:

...

(config)#interface lo

(config-if)#ip access-group loopback in

For an ACL for VTY, you create the ACL, configure it with rules, and associate the ACL to the terminal line in line mode:

...

(config)#line vty

(config-all-line)#ip access-group vty in

Loopback and VTY ACLs do not support the following:

• The default rule deny all. You must explicitly set up a deny all rule based on your requirements.

• VLAN-specific rules.

• Rules with TCP flags.

• Rules with dscp, fragments, log, precedence, and sample parameters.

Usage: Timed ACL on interfaces

You create a timer range that is identified by a name and configured with a start time, end time, and frequency. Once you create the time range, you can tie the ACL configuration to the time-range object. This allows you to create an access group that is enabled when the timer has started and disabled when the timer ends. You can also disassociate an access group from the timer if needed.

ip access-list

Use this command to define a named access control list (ACL) that determines whether to accept or drop an incoming IP packet based on specifications configured under the ACL. An ACL is made up of one or more ACL specifications.

Each packet that arrives at the device is compared to each specification in each ACL in the order that they are defined. The device continues to look until it has a match. If no match is found and the device reaches the end of the list, the packet is denied by default. For this reason, place the most frequently occurring specifications at the top of the list.

The device stops checking the specifications after a match occurs.

There is an implied deny specification for traffic that is not permitted. Implied specification can be updated to permit if the use-case is to deny a certain set of traffic.

Use the no form of this command to remove an ACL

ip access-list tcp|udp

Use this command to define a named access control list (ACL) that determines whether to accept or drop an incoming packet based on the criteria specified match criteria.

This form of this command filters packets based on source and destination IP address along with protocol (TCP or UDP) and port.

Use the no form of this command to remove an ACL specification.

Note: Configuring same filter again with change of sequence number or change of action will result in update of sequence number or filter action.

Note: TCP flags options and range options like neq, gt, lt and range are not supported by hardware in egress direction.

Note: Both Ack and established flag in tcp have same functionality in hardware.

ipv6 access-group

Use this command to attach an IPv6 access list to an interface to filter incoming or outgoing packets.

When you attach an access list to a VLAN interface or LAG interface as well as to a physical interface that is a member of that LAG and/or VLAN interface, the priority order is:

1. VLAN interface

2. LAG interface

3. Physical interface

Note: To attach an IPv6 access-group on interface, the IPv6 TCAM group should be enabled. To enable ingress-IPv6 /egress-IPv6, see the hardware-profile filter (XGS) command.

The time-range parameter is optional. If used, the access-group is tied to the timer specified.

To delete the access-group, use the no form of this command without a time-range.

Note: To attach IPv6 ACL in the ingress direction ingress-ipv6 TCAM group needs to be enabled.

Egress TCAMs do not auto-expand beyond 256 entries if any entry includes a policer action. Therefore, the total number of configurable entries in the egress direction is limited to 256.

Command Syntax

ipv6 access-group NAME in (time-range TR_NAME|)

no ipv6 access-group NAME in (time-range TR_NAME|)

Parameters

NAME

Access list name.

TR_NAME

Time range name set with the time-range command.

Command Mode

Interface mode

Applicability

This command was introduced before OcNOS version 1.3. The time-range parameter was added in OcNOS-SP version 5.0.

Examples

#configure terminal

(config)#ipv6 access-list mylist

(config-ipv6-acl)#permit ipv6 any any

(config-ipv6-acl)#exit

(config)#hardware-profile filter ingress-ipv6 enable

(config)#interface xe3

(config-if)#ipv6 access-group mylist in

(config)#interface xe3

(config-if)#no ipv6 access-group mylist in

(config)#interface xe3

(config-if)#ipv6 access-group mylist in time-range TIMER1

(config)#interface xe3

(config-if)#no ipv6 access-group mylist in time-range TIMER1

ipv6 access-list

Use this command to define a IPv6 access control list (ACL) that determines whether to accept or drop an incoming IPv6 packet based on specifications configured under the ACL. An ACL is made up of one or more ACL specifications.

The device stops checking the specifications after a match occurs.

There is an implied deny specification for traffic that is not permitted. Implied specification can be updated to permit if the use-case is to deny a certain set of traffic.

Use the no form of this command to remove an ACL.

Note: For IPv6 routing protocols need neighbor discovery for the session to establish. Applying Ipv6 acls implicitly drops all the icmpv6 packets, thereby affecting the protocol sessions. To overcome this problem, implicit icmpv6 permit rule is added in the IPv6 acls.

If required behavior is to deny the icmpv6, implicit rule can be deleted.

For example,

To create an ipv6 acl, execute the following:

(config)#ipv6 access-list ipv6-acl

#show ipv6 access-lists

IPv6 access list ip1

268435453 permit icmpv6 any any

To delete this rule, execute the following:

(config)#ipv6 access-list ipv6-acl

(config-ipv6-acl)# no 268435453 permit icmpv6 any any

#show ipv6 access-lists

IPv6 access list ip1

Command Syntax

ipv6 access-list NAME

no ipv6 access-list NAME

Parameters

NAME

Access-list name.

Command Mode

Configure mode

Applicability

This command was introduced before OcNOS version 1.3.

Implicit rule is introduced in OcNOS version 2.0.

Examples

#configure terminal

(config)#ipv6 access-list ipv6-acl-01

(config-ipv6-acl)#exit

ipv6 access-list default

Use this command to modify the default rule action of access-list. Default rule is applicable only when access-list is attached to interface. Default rule will have the lowest priority and only the IPv6 packets not matching any of the user defined rules match default rule.

Command Syntax

default (deny-all|permit-all) (log|) (sample|)

Parameters

deny-all

Drop all packets.

permit-all

Accept all packets.

log

Log the packets matching the filter (in-direction only).

sample

Sample the packets matching the filter (in-direction only).

Command Mode

IPv6 access-list mode

Applicability

This command was introduced before OcNOS version 1.3.

Examples

#configure terminal

(config)#ip access-list ipv6-acl-01

(config-ipv6-acl)#default permit-all sample

ipv6 access-list filter

Use this command to define an access-control entry in an access control list (ACL) that determines whether to accept or drop an IPv6 packet based on the criteria specified. This form of this command filters packets based on:

• Protocol

• Source IP address

• Destination IP address

Use the no form of this command to remove an ACL specification. ACL specification can be removed using the sequence number as well.

Note: Configuring same filter again with change of sequence number or change of action will result in update of sequence number or filter action.

Note: For IPv6 source and destination address filters, only the network part from the address (upper 64 bits) is supported due to hardware restriction. If the address length is more than 64 bits, it cannot be applied on the interfaces but it can be used with distributed list in control plane protocols.

ipv6 access-list tcp|udp

Use this command to define a IPv6 access control list (ACL) specification that determines whether to accept or drop an incoming IPv6 packet based on the criteria that you specify. This form of this command filters packets based on source and destination IPv6 address along with protocol (TCP or UDP) and port.

Use the no form of this command to remove an ACL specification.

Note: Configuring same filter again with change of sequence number or change of action will result in update of sequence number or filter action.

(config-ipv6-acl)#deny udp any eq tftp

(config-ipv6-acl)#deny tcp fd22:bf66:78a4:10a2::/64 fdf2:860a:746a:e49c::/64 eq ssh

line vty

Use this command to move or change to ALL LINE VTY mode.

Command Syntax

line vty

Parameters

Command Mode

Configure mode

Applicability

This command was introduced from OcNOS version 1.3.8

Examples

The following example shows entering all line mode (note the change in the prompt).

#configure terminal

(config)#line vty

(config-all-line)#exit

mac access-group

Use this command to attach a MAC access list to an interface to filter incoming packets.

When you attach an access list to a VLAN interface or LAG interface as well as to a physical interface that is a member of that LAG and/or VLAN interface, the priority order is:

1. VLAN interface

2. LAG interface

3. Physical interface

The time-range parameter is optional. If used, the access-group is tied to the timer specified.

To delete the access-group, use the no form of this command without a time-range.

Note: An access-group on egress access-group on egress direction uses the TCAM group used by the QoS output service policy. Therefore, actions are unpredictable when conflicting matches are configured on same interface. IP Infusion Inc. recommends avoiding such a configuration. Otherwise, you need to configure the priority (in QoS) or the sequence number (in ACL) carefully to handle such cases.

Egress TCAMs do not auto-expand beyond 256 entries if any entry includes a policer action. Therefore, the total number of configurable entries in the egress direction is limited to 256.

mac access-list

Use this command to define a MAC access control list (ACL) that determines whether to accept or drop an incoming packet based on specifications configured under the ACL. An ACL is made up of one or more ACL specifications.

The device stops checking the specifications after a match occurs.

There is an implied deny specification for traffic that is not permitted. Implied specification can be updated to permit if the use-case is to deny a certain set of traffic.

Use the no form of this command to remove the ACL.

Command Syntax

mac access-list NAME

no mac access-list NAME

Parameters

NAME

Access-list name.

Command Mode

Configure mode

Applicability

This command was introduced before OcNOS version 1.3.

Examples

#configure terminal

(config)#mac access-list mac-acl-01

(config-mac-acl)#exit

mac access-list default

Use this command to modify the default rule action of access-list. Default rule is applicable only when access-list is attached to interface. Default rule will have the lowest priority and only the packets not matching any of the user defined rules match default rule.

Command Syntax

default (deny-all|permit-all) (log|) (sample|)

Parameters

deny-all

Drop all packets.

permit-all

Accept all packets.

log

Log the packets matching the filter (in-direction only).

sample

Sample the packets matching the filter (in-direction only).

Command Mode

MAC access-list mode

Applicability

This command was introduced before OcNOS version 1.3.

Examples

#configure terminal

(config)#mac access-list mac-acl-01

(config-mac-acl)#default permit-all sample

mac access-list filter

Use this command to define an access control entry (ACE) in a MAC access control list (ACL) that determines whether to permit or deny packets with the given source and destination MAC, ethertype, CoS, and VLAN identifiers.

Use the no form of this command to remove an ACL specification. ACL specification can be removed using the sequence number as well.

Note: Configuring same filter again with change of sequence number or change of action will result in update of sequence number or filter action.

Command Syntax

no (<1-268435453>)

Parameters

deny

Drop the packet.

permit

Accept the packet.

<1-268435453>
