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: •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. When you use this keyword, only the other keywords and arguments that apply to all IPv4 protocols are available. They include the following: –dscp –precedence •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 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) •if—Expedited Forwarding (101110)
precedence precedence	(Optional) Specifies that the rule matches only packets that have an IP Precedence field with the value specified by the precedence argument. 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)

It can also be one of the following keywords: •dvmrp—Distance Vector Multicast Routing Protocol •host-query—Host query •host-report—Host report •pim—Protocol Independent Multicast •trace—Multicast trace
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.
flags	(TCP only; Optional) TCP control bit flags that the rule matches. The value of the flags argument must be one or more of the following keywords: •ack •fin •psh •rst •syn •urg

Command History


Release	Modification
4.0(4)SV1(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.

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:

•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:

n1000v(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:

n1000v(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:

n1000v(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.

Layer 3 packets—source-mac

Command Modes

Global configuration (config)

Supported User Roles

network-admin

Command History


Release	Modification
4.0(4)SV1(1)	This command was introduced.

Usage Guidelines

When you do not specify a module, you are configuring load balancing for the entire device. When you use the module parameter, you are configuring load balancing for the specified modules

Valid method values are as follows:

•dest-ip-port—Loads distribution on the destination IP address and L4 port.

•dest-ip-port-vlan—Loads distribution on the destination IP address, L4 port, and VLAN.

•destination-ip-vlan—Loads distribution on the destination IP address and VLAN

•destination-mac—Loads distribution on the destination MAC address.

•destination-port—Loads distribution on the destination L4 port.

•source-dest-ip-port—Loads distribution on the source and destination IP address and L4 port.

•source-dest-ip-port-vlan—Loads distribution on the source and destination IP address, L4 port, and VLAN.

•source-dest-ip-vlan—Loads distribution on the source and destination IP address and VLAN.

•source-dest-mac—Loads distribution on the source and destination MAC address.

•source-dest-port—Loads distribution on the source and destination L4 port.

•source-ip-port—Loads distribution on the source IP address.

•source-ip-port-vlan—Loads distribution on the source IP address, L4, and VLAN

•source-ip-vlan—Loads distribution on the source IP address and VLAN.

•source-mac—Loads distribution on the source MAC address.

•source-port—Loads distribution on the source port.

•source-virtual-port-id—Loads distribution on the source virtual port ID.

•vlan-only—Loads distribution on the VLAN only.

Use the module argument to configure the module independently for port-channeling and load-balancing mode. When you do this, the remaining module use the current load-balancing method configured for the entire device, or the default method if you have not configured a method for the entire device. When you enter the no argument in conjunction with a module argument, the load-balancing method for the specified module takes the current load-balancing method that is in use for the entire device. If you configured a load-balancing method for the entire device, the specified module uses that configured method, rather than the default source-mac. The per module configuration takes precedence over the load-balancing method configured for the entire device.

Use the option that provides the balance criteria with the greatest variety in your configuration. For example, if the traffic on a port channel is going only to a single MAC address and you use the destination MAC address as the basis of port channel load balancing, the port channel always chooses the same link in that port channel; using source addresses or IP addresses might result in better load balancing.

Examples

This example shows how to set the load-balancing method for the entire device to use the source port:

n1000v(config)# port-channel load-balance ethernet src-port

n1000v(config)#

Command	Description
show port-channel load-balance	Displays information on port-channel load balancing.

Syntax Description


type	(Optional) Specify interface of type ethernet or vethernet. The default is vethernet.
profilename	Specifies the port profile name. The name can be up to 80 characters in length.

Defaults

Default type is vethernet.

Release	Modification
4.0(4)SV1(2)	Port profiles are not classified as uplink, but are, instead, configured as type Ethernet or type vEthernet.
4.0(4)SV1(1)	This command was introduced.

Usage Guidelines

The port profile name must be unique for each port profile on the Cisco Nexus 1000V.

The port profile type can be Ethernet or vEthernet. Once configured, the type cannot be changed.

Defining a port profile type as Ethernet allows the port profile to be used for physical (Ethernet) ports. In the vCenter Server, the corresponding port group can be selected and assigned to physical ports (PNICs).

If a port profile is configured as an Ethernet type, then it cannot be used to configure VMware virtual ports.

Examples

This example shows how to create an Ethernet type port profile with the name AccessProf:

n1000v# configure terminal

n1000v(config)# port-profile type ethernet AccessProf

n1000v(config-port-prof)
