•At least eight characters long

•Does not contain many consecutive characters (such as "abcd")

•Does not contain many repeating characters (such as "aaabbb")

•Does not contain dictionary words

•Does not contain proper names

•Contains both uppercase and lowercase characters

•Contains numbers

The following are examples of strong passwords:

•If2CoM18

•2004AsdfLkj30

•Cb1955S21

periodic

To specify a time range that is active one or more times per week, use the periodic command. To remove a periodic time range, use the no form of this command.

[sequence-number] periodic weekday time to [weekday] time

no {sequence-number | periodic weekday time to [weekday] time}

[sequence-number] periodic list-of-weekdays time to time

no {sequence-number | periodic list-of-weekdays time to time}

Syntax Description

sequence-number	(Optional) Sequence number of the rule, which causes the device to insert the command in that numbered position in the time range. Sequence numbers maintain the order of rules within a time range. A sequence number can be any integer between 1 and 4294967295. By default, the first rule in a time range has a sequence number of 10. If you do not specify a sequence number, the device adds the rule to the end of the time range and assigns a sequence number that is 10 greater than the sequence number of the preceding rule. Use the resequence command to reassign sequence numbers to rules.
weekday	Day of the week that the range begins or ends. The first occurrence of this argument is the day that the range starts. The second occurrence is the day that the range ends. If the second occurrence is omitted, the end of the range is on the same day as the start of the range. The following keywords are valid values for the weekday argument: •monday •tuesday •wednesday •thursday •friday •saturday •sunday
time	Time of day that the range starts or ends. The first occurrence of this argument is the time that the range begins. The second occurrence of this argument is the time that the range ends. You can specify the time argument in 24-hour notation, in the format hours:minutes or hours:minutes:seconds. For example, 8:00 a.m. is 8:00 and 8:00 p.m. is 20:00.
to	Separates the first and second occurrences of the time argument.
list-of-weekdays	(Optional) Days that the range is in effect. Valid values of this argument are as follows: •A space-delimited list of weekdays, such as the following: monday thursday friday •daily—All days of the week. •weekdays—Monday through Friday. •weekend—Saturday through Sunday.

Syntax Description

sequence-number	(Optional) Sequence number of the permit command, which causes the device to insert the command in that numbered position in the access list. Sequence numbers maintain the order of rules within an ACL. A sequence number can be any integer between 1 and 4294967295. By default, the first rule in an ACL has a sequence number of 10. If you do not specify a sequence number, the device adds the rule to the end of the ACL and assigns a sequence number that is 10 greater than the sequence number of the preceding rule. Use the resequence command to reassign sequence numbers to rules.
ip	Introduces the IP address portion of the rule.
any	Specifies that any host matches the part of the rule that contains the any keyword. You can use any to specify the sender IP address, target IP address, sender MAC address, and target MAC address.
host sender-IP	Specifies that the rules matches ARP packets only when the sender IP address in the packet matches the value of the sender-IP argument. Valid values for the sender-IP argument are IPv4 addresses in dotted-decimal format.
sender-IP sender-IP-mask	IPv4 address and mask for the set of IPv4 addresses that the sender IP address in the packet can match. The sender-IP and sender-IP-mask argument must be in dotted-decimal format. Specifying 255.255.255.255 as the sender-IP-mask argument is the equivalent of using the host keyword.
mac	Introduces the MAC address portion of the rule.
host sender-MAC	Specifies that the rule matches ARP packets only when the sender MAC address in the packet matches the value of the sender-MAC argument. Valid values for the sender-MAC argument are MAC addresses in dotted-hexadecimal format.
sender-MAC sender-MAC-mask	MAC address and mask for the set of MAC addresses that the sender MAC address in the packet can match. The sender-MAC and sender-MAC-mask argument must be in dotted-hexadecimal format. Specifying ffff.ffff.ffff as the sender-MAC-mask argument is the equivalent of using the host keyword.
log	(Optional) Specifies that the device logs ARP packets that match the rule.
request	(Optional) Specifies that the rule applies only to packets containing ARP request messages. Note If you omit both the request and the response keywords, the rule applies to all ARP messages.
response	(Optional) Specifies that the rule applies only to packets containing ARP response messages. Note If you omit both the request and the response keywords, the rule applies to all ARP messages.
host target-IP	Specifies that the rule matches ARP packets only when the target IP address in the packet matches the value of the target-IP argument. You can specify host target-IP only when you use the response keyword. Valid values for the target-IP argument are IPv4 addresses in dotted-decimal format.
target-IP target-IP-mask	IPv4 address and mask for the set of IPv4 addresses that the target IP address in the packet can match. You can specify target-IP target-IP-mask only when you use the response keyword. The target-IP and target-IP-mask argument must be in dotted-decimal format. Specifying 255.255.255.255 as the target-IP-mask argument is the equivalent of using the host keyword.
host target-MAC	Specifies that the rule matches ARP packets only when the target MAC address in the packet matches the value of the target-MAC argument. You can specify host target-MAC only when you use the response keyword. Valid values for the target-MAC argument are MAC addresses in dotted-hexadecimal format.
target-MAC target-MAC-mask	MAC address and mask for the set of MAC addresses that the target MAC address in the packet can match. You can specify target-MAC target-MAC-mask only when you use the response keyword. The target-MAC and target-MAC-mask argument must be in dotted-hexadecimal format.

Command History

Release	Modification
4.0(1)	This command was introduced.

Usage Guidelines

A newly created ARP ACL contains no rules.

If you do not specify a sequence number, the device assigns to the rule a sequence number that is 10 greater than the last rule in the ACL.

When the device applies an ARP ACL to a packet, it evaluates the packet with every rule in the ACL. The device enforces the first rule that has conditions that are satisfied by the packet. When the conditions of more than one rule are satisfied, the device enforces the rule with the lowest sequence number.

If you do not specify either the response or request keyword, the rule applies to packets that contain any ARP message.

This command does not require a license.

Examples

This example shows how to enter ARP access list configuration mode for an ARP ACL named arp-acl-01 and add a rule that permits ARP request messages that contain a sender IP address that is within the 10.32.143.0 subnet:

switch# conf t

switch(config)# arp access-list arp-acl-01

switch(config-arp-acl)# permit request ip 10.32.143.0 255.255.255.0 mac any

Syntax Description

sequence-number	(Optional) Sequence number of the permit command, which causes the device to insert the command in that numbered position in the access list. Sequence numbers maintain the order of rules within an ACL. A sequence number can be any integer between 1 and 4294967295. By default, the first rule in an ACL has a sequence number of 10. If you do not specify a sequence number, the device adds the rule to the end of the ACL and assigns a sequence number that is 10 greater than the sequence number of the preceding rule. Use the resequence command to reassign sequence numbers to rules.
protocol	Name or number of the protocol of packets that the rule matches. For details about the methods that you can use to specify this argument, see "Protocol" in the "Usage Guidelines" section.
source	Source IPv4 addresses that the rule matches. For details about the methods that you can use to specify this argument, see "Source and Destination" in the "Usage Guidelines" section.
destination	Destination IPv4 addresses that the rule matches. For details about the methods that you can use to specify this argument, see "Source and Destination" in the "Usage Guidelines" section.
dscp dscp	(Optional) Specifies that the rule matches only those packets with the specified 6-bit differentiated services value in the DSCP field of the IP header. The dscp argument can be one of the following numbers or keywords: •0-63—The decimal equivalent of the 6 bits of the DSCP field. For example, if you specify 10, the rule matches only those packets that have the following bits in the DSCP field: 001010. •af11—Assured Forwarding (AF) class 1, low drop probability (001010) •af12—AF class 1, medium drop probability (001100) •af13—AF class 1, high drop probability (001110) •af21—AF class 2, low drop probability (010010) •af22—AF class 2, medium drop probability (010100) •af23—AF class 2, high drop probability (010110) •af31—AF class 3, low drop probability (011010) •af32—AF class 3, medium drop probability (011100) •af33—AF class 3, high drop probability (011110) •af41—AF class 4, low drop probability (100010) •af42—AF class 4, medium drop probability (100100) •af43—AF class 4, high drop probability (100110) •cs1—Class-selector (CS) 1, precedence 1 (001000) •cs2—CS2, precedence 2 (010000) •cs3—CS3, precedence 3 (011000) •cs4—CS4, precedence 4 (100000) •cs5—CS5, precedence 5 (101000) •cs6—CS6, precedence 6 (110000) •cs7—CS7, precedence 7 (111000) •default—Default DSCP value (000000) •ef—Expedited Forwarding (101110)

The precedence argument can be a number or a keyword, as follows: •0-7—Decimal equivalent of the 3 bits of the IP Precedence field. For example, if you specify 3, the rule matches only packets that have the following bits in the DSCP field: 011. •critical—Precedence 5 (101) •flash—Precedence 3 (011) •flash-override—Precedence 4 (100) •immediate—Precedence 2 (010) •internet—Precedence 6 (110) •network—Precedence 7 (111) •priority—Precedence 1 (001) •routine—Precedence 0 (000)
fragments	(Optional) Specifies that the rule matches only those packets that are noninitial fragments. You cannot specify this keyword in the same rule that you specify Layer 4 options, such as a TCP port number, because the information that the devices requires to evaluate those options is contained only in initial fragments.
log	(Optional) Specifies that the device generates an informational logging message about each packet that matches the rule. The message includes the following information: •Whether the protocol was TCP, UDP, ICMP or a number protocol •Source and destination addresses •Source and destination port numbers, if applicable
time-range time-range-name	(Optional) Specifies the time range that applies to this rule. Use the time-range command to a time range.

operator port [port]	(Optional; TCP and UDP only) Rule matches only packets that are from a source port or sent to a destination port that satisfies the conditions of the operator and port arguments. Whether these arguments apply to a source port or a destination port depends upon whether you specify them after the source argument or after the destination argument. The port argument can be the name or the number of a TCP or UDP port. Valid numbers are integers from 0 to 65535. For listings of valid port names, see "TCP Port Names" and "UDP Port Names" in the "Usage Guidelines" section. A second port argument is required only when the operator argument is a range. The operator argument must be one of the following keywords: •eq—Matches only if the port in the packet is equal to the port argument. •gt—Matches only if the port in the packet is greater than and not equal to the port argument. •lt—Matches only if the port in the packet is less than and not equal to the port argument. •neq—Matches only if the port in the packet is not equal to the port argument. •range—Requires two port arguments and matches only if the port in the packet is equal to or greater than the first port argument and equal to or less than the second port argument.

4.1(2)	Support was added for the following: •The ahp, eigrp, esp, gre, nos, ospf, pcp, and pim protocol keywords. •The packet-length keyword.
4.0(1)	This command was introduced.

Usage Guidelines

When the device applies an IPv4 ACL to a packet, it evaluates the packet with every rule in the ACL. The device enforces the first rule that has conditions that are satisfied by the packet. When the conditions of more than one rule are satisfied, the device enforces the rule with the lowest sequence number.

This command does not require a license.

Protocol

You can specify the protocol of packets that the rule applies to by the protocol name or the number of the protocol. If you want the rule to apply to all IPv4 traffic, use the ip keyword.

The protocol keyword that you specify affects the additional keywords and arguments that are available. Unless otherwise specified, only the other keywords that apply to all IPv4 protocols are available. Those keywords include the following:

–dscp

–fragments

–log

–packet-length

–precedence

–time-range

Valid protocol numbers are from 0 to 255.

Valid protocol names are the following keywords:

•ahp—Specifies that the rule applies to authentication header protocol (AHP) traffic only.

•eigrp—Specifies that the rule applies to Enhanced Interior Gateway Routing Protocol (EIGRP) traffic only.

•esp—Specifies that the rule applies to Encapsulating Security Protocol (ESP) traffic only.

•gre—Specifies that the rule applies to General Routing Encapsulation (GRE) traffic only.

•icmp—Specifies that the rule applies to ICMP traffic only. When you use this keyword, the icmp-message argument is available, in addition to the keywords that are available for all valid values of the protocol argument.

•igmp—Specifies that the rule applies to IGMP traffic only. When you use this keyword, the igmp-type argument is available, in addition to the keywords that are available for all valid values of the protocol argument.

•ip—Specifies that the rule applies to all IPv4 traffic.

•nos—Specifies that the rule applies to KA9Q NOS-compatible IP-over-IP tunneling traffic only.

•ospf—Specifies that the rule applies to Open Shortest Path First (OSPF) traffic only.

•pcp—Specifies that the rule applies to payload compression protocol (PCP) traffic only.

•pim—Specifies that the rule applies to protocol-independent multicast (PIM) traffic only.

•tcp—Specifies that the rule applies to TCP traffic only. When you use this keyword, the flags and operator arguments and the portgroup and established keywords are available, in addition to the keywords that are available for all valid values of the protocol argument.

•udp—Specifies that the rule applies to UDP traffic only. When you use this keyword, the operator argument and the portgroup keyword are available, in addition to the keywords that are available for all valid values of the protocol argument.

Source and Destination

You can specify the source and destination arguments in one of several ways. In each rule, the method you use to specify one of these arguments does not affect how you specify the other. When you configure a rule, use the following methods to specify the source and destination arguments:

•IP address group object—You can use an IPv4 address group object to specify a source or destination argument. Use the object-group ip address command to create and change IPv4 address group objects. The syntax is as follows:

addrgroup address-group-name

The following example shows how to use an IPv4 address object group named lab-gateway-svrs to specify the destination argument:

switch(config-acl)# permit ip any addrgroup lab-gateway-svrs

•Address and network wildcard—You can use an IPv4 address followed by a network wildcard to specify a host or a network as a source or destination. The syntax is as follows:

IPv4-address network-wildcard

The following example shows how to specify the source argument with the IPv4 address and network wildcard for the 192.168.67.0 subnet:

switch(config-acl)# permit tcp 192.168.67.0 0.0.0.255 any

•Address and variable-length subnet mask—You can use an IPv4 address followed by a variable-length subnet mask (VLSM) to specify a host or a network as a source or destination. The syntax is as follows:

IPv4-address/prefix-len

The following example shows how to specify the source argument with the IPv4 address and VLSM for the 192.168.67.0 subnet:

switch(config-acl)# permit udp 192.168.67.0/24 any

•Host address—You can use the host keyword and an IPv4 address to specify a host as a source or destination. The syntax is as follows:

host IPv4-address

This syntax is equivalent to IPv4-address/32 and IPv4-address 0.0.0.0.

The following example shows how to specify the source argument with the host keyword and the 192.168.67.132 IPv4 address:

switch(config-acl)# permit icmp host 192.168.67.132 any

•Any address—You can use the any keyword to specify that a source or destination is any IPv4 address. For examples of the use of the any keyword, see the examples in this section. Each example shows how to specify a source or destination by using the any keyword.

ICMP Message Types

The icmp-message argument can be one of the following keywords:

•administratively-prohibited—Administratively prohibited

•alternate-address—Alternate address

•conversion-error—Datagram conversion

Syntax Description

sequence-number	(Optional) Sequence number of the permit command, which causes the device to insert the command in that numbered position in the access list. Sequence numbers maintain the order of rules within an ACL. A sequence number can be any integer between 1 and 4294967295. By default, the first rule in an ACL has a sequence number of 10. If you do not specify a sequence number, the device adds the rule to the end of the ACL and assigns a sequence number that is 10 greater than the sequence number of the preceding rule. Use the resequence command to reassign sequence numbers to rules.
protocol	Name or number of the protocol of packets that the rule matches. Valid numbers are from 0 to 255. Valid protocol names are the following keywords: •ahp—Specifies that the rule applies to Authentication Header Protocol (AHP) traffic only. When you use this keyword, only the other keywords and arguments that apply to all IPv6 protocols are available. •esp—Specifies that the rule applies to Encapsulating Security Payload (ESP) traffic only. When you use this keyword, only the other keywords and arguments that apply to all IPv6 protocols are available. •icmp—Specifies that the rule applies to ICMP traffic only. When you use this keyword, the icmp-message argument is available, in addition to the keywords that are available for all valid values of the protocol argument. •ipv6—Specifies that the rule applies to all IPv6 traffic. When you use this keyword, only the other keywords and arguments that apply to all IPv6 protocols are available. •pcp—Specifies that the rule applies to Payload Compression Protocol (PCP) traffic only. When you use this keyword, only the other keywords and arguments that apply to all IPv6 protocols are available. •sctp—Specifies that the rule applies to Stream Control Transmission Protocol (SCTP) traffic only. When you use this keyword, the operator argument and the portgroup keyword are available, in addition to the keywords that are available for all valid values of the protocol argument. •tcp—Specifies that the rule applies to TCP traffic only. When you use this keyword, the flags and operator arguments and the portgroup and established keywords are available, in addition to the keywords that are available for all valid values of the protocol argument. •udp—Specifies that the rule applies to UDP traffic only. When you use this keyword, the operator argument and the portgroup keyword are available, in addition to the keywords that are available for all valid values of the protocol argument.
source	Source IPv6 addresses that the rule matches. For details about the methods that you can use to specify this argument, see "Source and Destination" in the "Usage Guidelines" section.
destination	Destination IPv6 addresses that the rule matches. For details about the methods that you can use to specify this argument, see "Source and Destination" in the "Usage Guidelines" section.
dscp dscp	(Optional) Specifies that the rule matches only packets with the specified 6-bit differentiated services value in the DSCP field of the IPv6 header. The dscp argument can be one of the following numbers or keywords: •0-63—The decimal equivalent of the 6 bits of the DSCP field. For example, if you specify 10, the rule matches only packets that have the following bits in the DSCP field: 001010. •af11—Assured Forwarding (AF) class 1, low drop probability (001010) •af12—AF class 1, medium drop probability (001100) •af13—AF class 1, high drop probability (001110) •af21—AF class 2, low drop probability (010010) •af22—AF class 2, medium drop probability (010100) •af23—AF class 2, high drop probability (010110) •af31—AF class 3, low drop probability (011010) •af32—AF class 3, medium drop probability (011100) •af33—AF class 3, high drop probability (011110) •af41—AF class 4, low drop probability (100010) •af42—AF class 4, medium drop probability (100100) •af43—AF class 4, high drop probability (100110) •cs1—Class-selector (CS) 1, precedence 1 (001000) •cs2—CS2, precedence 2 (010000) •cs3—CS3, precedence 3 (011000) •cs4—CS4, precedence 4 (100000) •cs5—CS5, precedence 5 (101000) •cs6—CS6, precedence 6 (110000) •cs7—CS7, precedence 7 (111000) •default—Default DSCP value (000000) •ef—Expedited Forwarding (101110)
flow-label flow-label-value	(Optional) Specifies that the rule matches only IPv6 packets whose Flow Label header field has the value specified by the flow-label-value argument. The flow-label-value argument can be an integer from 0 to 1048575.
fragments	(Optional) Specifies that the rule matches noninitial fragmented packets only. The device considers noninitial fragmented packets to be packets with a fragment extension header that contains a fragment offset that is not equal to zero. You cannot specify this keyword in the same rule that you specify Layer 4 options, such as a TCP port number, because the information that the devices requires to evaluate those options is contained only in initial fragments.
log	(Optional) Specifies that the device generates an informational logging message about each packet that matches the rule. The message includes the following information: •Whether the protocol was TCP, UDP, ICMP or a number protocol •Source and destination addresses •Source and destination port numbers, if applicable
time-range time-range-name	(Optional) Specifies the time range that applies to this rule. You can configure a time range by using the time-range command.

icmp-type [icmp-code]	(ICMP only: Optional) ICMP message type that the rule matches. Valid values for the icmp-type argument are an integer from 0 to 255. If the ICMP message type supports message codes, you can use the icmp-code argument to specify the code that the rule matches. For more information about ICMP message types and codes, see http://www.iana.org/assignments/icmp-parameters.
operator port [port]	(Optional; TCP, UDP, and SCTP only) Rule matches only packets that are from a source port or sent to a destination port that satisfies the conditions of the operator and port arguments. Whether these arguments apply to a source port or a destination port depends upon whether you specify them after the source argument or after the destination argument. The port argument can be the name or the number of a TCP or UDP port. Valid numbers are integers from 0 to 65535. For listings of valid port names, see "TCP Port Names" and "UDP Port Names" in the "Usage Guidelines" section. A second port argument is required only when the operator argument is a range. The operator argument must be one of the following keywords: •eq—Matches only if the port in the packet is equal to the port argument. •gt—Matches only if the port in the packet is greater than and not equal to the port argument. •lt—Matches only if the port in the packet is less than and not equal to the port argument. •neq—Matches only if the port in the packet is not equal to the port argument. •range—Requires two port arguments and matches only if the port in the packet is equal to or greater than the first port argument and equal to or less than the second port argument.
portgroup portgroup	(Optional; TCP, UDP, and SCTP only) Specifies that the rule matches only packets that are from a source port or to a destination port that is a member of the IP port-group object specified by the portgroup argument. Whether the port-group object applies to a source port or a destination port depends upon whether you specify it after the source argument or after the destination argument. Use the object-group ip port command to create and change IP port-group objects.
established	(TCP only; Optional) Specifies that the rule matches only packets that belong to an established TCP connection. The device considers TCP packets with the ACK or RST bits set to belong to an established connection.
flags	(TCP only; Optional) Rule matches only packets that have specific TCP control bit flags set. The value of the flags argument must be one or more of the following keywords: •ack •fin •psh •rst •syn •urg
packet-length operator packet-length [packet-length]	(Optional) Rule matches only packets that have a length in bytes that satisfies the condition specified by the operator and packet-length arguments. Valid values for the packet-length argument are whole numbers from 20 to 9210. The operator argument must be one of the following keywords: •eq—Matches only if the packet length in bytes is equal to the packet-length argument. •gt—Matches only if the packet length in bytes is greater than the packet-length argument. •lt—Matches only if the packet length in bytes is less than the packet-length argument. •neq—Matches only if the packet length in bytes is not equal to the packet-length argument. •range—Requires two packet-length arguments and matches only if the packet length in bytes is equal to or greater than the first packet-length argument and equal to or less than the second packet-length argument.

Usage Guidelines

A newly created IPv6 ACL contains no rules.

When the device applies an IPv6 ACL to a packet, it evaluates the packet with every rule in the ACL. The device enforces the first rule whose conditions are satisfied by the packet. When the conditions of more than one rule are satisfied, the device enforces the rule with the lowest sequence number.

This command does not require a license.

Source and Destination

You can specify the source and destination arguments in one of several ways. In each rule, the method you use to specify one of these arguments does not affect how you specify the other. When you configure a rule, use the following methods to specify the source and destination arguments:

•IPv6 address group object—You can use an IPv6 address group object to specify a source or destination argument. Use the object-group ipv6 address command to create and change IPv6 address group objects. The syntax is as follows:

addrgroup address-group-name

The following example shows how to use an IPv6 address object group named lab-svrs-1301 to specify the destination argument:

switch(config-acl)# permit ipv6 any addrgroup lab-svrs-1301

•Address and variable-length subnet mask—You can use an IPv6 address followed by a variable-length subnet mask (VLSM) to specify a host or a network as a source or destination. The syntax is as follows:

IPv6-address/prefix-len

The following example shows how to specify the source argument with the IPv6 address and VLSM for the 2001:0db8:85a3:: network:

switch(config-acl)# permit udp 2001:0db8:85a3::/48 any

•Host address—You can use the host keyword and an IPv6 address to specify a host as a source or destination. The syntax is as follows:

host IPv6-address

This syntax is equivalent to IPv6-address/128.

The following example shows how to specify the source argument with the host keyword and the 2001:0db8:85a3:08d3:1319:8a2e:0370:7344 IPv6 address:

switch(config-acl)# permit icmp host 2001:0db8:85a3:08d3:1319:8a2e:0370:7344 any

•Any address—You can use the any keyword to specify that a source or destination is any IPv6 address. For examples of the use of the any keyword, see the examples in this section. Each example shows how to specify a source or destination by using the any keyword.

When the conditions of more than one rule are satisfied, the device enforces the rule with the lowest sequence number.

This command does not require a license.

Source and Destination

You can specify the source and destination arguments in one of two ways. In each rule, the method you use to specify one of these arguments does not affect how you specify the other. When you configure a rule, use the following methods to specify the source and destination arguments:

•Address and mask—You can use a MAC address followed by a mask to specify a single address or a group of addresses. The syntax is as follows:

MAC-address MAC-mask 

The following example specifies the source argument with the MAC address 00c0.4f03.0a72:

switch(config-acl)# permit 00c0.4f03.0a72 0000.0000.0000 any

The following example specifies the destination argument with a MAC address for all hosts with a MAC vendor code of 00603e:

switch(config-acl)# permit any 0060.3e00.0000 0000.0000.0000

•Any address—You can use the any keyword to specify that a source or destination is any MAC address. For examples of the use of the any keyword, see the examples in this section. Each of the examples shows how to specify a source or destination by using the any keyword.

MAC Protocols

The protocol argument can be the MAC protocol number or a keyword. The protocol number is a four-byte hexadecimal number prefixed with 0x. Valid protocol numbers are from 0x0 to 0xffff. Valid keywords are the following:

•aarp—Appletalk ARP (0x80f3)

•appletalk—Appletalk (0x809b)

•decnet-iv—DECnet Phase IV (0x6003)

•diagnostic—DEC Diagnostic Protocol (0x6005)

default-result permit	Specifies that, during non-atomic updates, the device permits traffic that the updated ACL applies to.

Defaults

atomic

Command Modes

Global configuration

Supported User Roles

network-admin
vdc-admin

Command History

Release	Modification
4.1(2)	This command was deprecated and replace with the hardware access-list update command.
4.0(1)	This command was introduced.

Usage Guidelines

By default, a Cisco NX-OS device performs atomic ACL updates, which do not disrupt traffic that the updated ACL applies to; however, atomic updates require that the I/O modules that receive the updates have enough available resources to store each of the updated entries in the affected ACL. After the update occurs, the additional resources used for the update are freed. If the I/O module lacks the required resources, the device generates an error message and the ACL update to the I/O module fails.

If an I/O module lacks required resources, you can disable atomic updates by using the no platform access-list update atomic command; however, during the brief time required for the device to remove the old ACL and implement the updated ACL, traffic that the ACL applies to is dropped by default.

If you want to permit all traffic that the updated ACL applies during a non-atomic update, use the platform access-list update default-result permit command.

This command does not require a license.

Examples

This example shows how disable atomic updates to ACLs:

switch# config t

switch(config)# no platform access-list update atomic

This example shows how to permit affected traffic during a non-atomic ACL update:

switch# config t

switch(config)# platform access-list update default-result permit

This example shows how to revert to the atomic update method:

switch# config t

switch(config)# no platform access-list update default-result permit

switch(config)# platform access-list update atomic
