The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the Cisco Nexus 1000V commands that begin with the letter M.
To create a MAC access control list (ACL), use the mac access-list command. To remove the MAC ACL, use the no form of this command.
MAC ACL name. The name is case-sensitive, alphanumeric, and has a maximum of 64 characters. |
|
|
This example shows how to create a MAC ACL:
n1000v#
configure terminal
n1000v(config)#
mac access-list aL1
n1000v(config)#
|

To configure the aging time for entries in the Layer 2 table, use the mac address-table aging-time command. To return to the default settings, use the no form of this command.
mac address-table aging-time seconds [ vlan vlan-id ]
no mac address-table aging-time [ vlan vlan-id ]
|
|
Enter 0 seconds to disable the aging process.
The age value may be rounded off to the nearest multiple of 5 seconds. If the system rounds the value to a different value from that specified by the user (from the rounding process), the system returns an informational message.
When you use this command in the global configuration mode, the age values of all VLANs for which a configuration has not been specified are modified and those VLANs with specifically modified aging times are not modified. When you use the no form of this command without the VLAN parameter, only those VLANs that have not been specifically configured for the aging time reset to the default value. Those VLANs with specifically modified aging times are not modified.
When you use this command and specify a VLAN, the aging time for only the specified VLAN is modified. When you use the no form of this command and specify a VLAN, the aging time for the VLAN is returned to the current global configuration for the aging time, which may or may not be the default value of 300 seconds depending if the global configuration of the device for the aging time has been changed.
The aging time is counted from the last time that the switch detected the MAC address.
This example shows how to change the length of time an entry remains in the MAC address table to 500 seconds for the entire device:
n1000v(config)#
mac address-table aging-time 500
|
|

To add a static entry to the Layer 2 MAC address table, use the mac address-table static command. To delete the static entry, use the no form of this command.
mac address-table static mac-address vlan vlan-id { interface { interface-name } + | drop } [ auto-learn ]
no mac address-table static mac-address vlan vlan-id
|
|
You cannot apply the mac address-table static mac-address vlan vlan-id drop command to a multicast MAC address.
The output interface specified cannot be a VLAN interface or a Switched Virtual Interface (SVI).
Use the no form to remove entries that are profiled by the combination of specified entry information.
This example shows how to add a static entry to the MAC address table:
n1000v(config)#
mac address-table static 0050.3e8d.6400 vlan 3 interface ethernet 2/1
n1000v(config)#

To toggle the auto-mac-learning state on a vEthernet interface, use the mac auto-static-learn command. To disable the auto-mac-learning state, use the no form of this command.
Interface configuration (config-if)
Port profile configuration (config-port-profile)
|
|
This example shows how to configure the auto-mac-learning state on veth1:
|

---|---|
Adds a static MAC address in the Layer 2 MAC address table and saves it in the running configuration. |
To enable access control for port groups, use the mac port access-group command. To disable access control for port groups, use the no form of this command.
mac port access-group name { in | out }
no mac port access-group name { in | out }
Group name. The name is case-sensitive, alphanumeric, and can have a maximum of 64 characters. |
|
Port profile configuration (config-port-prof)
|
|
This example shows how to enable access control for port groups:

To define IP matching criteria for a NetFlow flow record, use the match ip command. To remove the matching criteria, use the no form of this command.
no match ip { protocol | tos }
Flow record configuration (config-flow-record)
|
|
This example shows how to configure IP matching criteria for a NetFlow flow record and then display the result:

Defines transport matching criteria for a NetFlow flow record. |
|
To define IPv4 matching criteria for a NetFlow flow record, use the match ipv4 command. To remove the matching criteria, use the no form of this command.
match ipv4 { source | destination } address
no match ipv4 { source | destination } address
Flow record configuration (config-flow-record)
|
|
This example shows how to configure IPv4 matching criteria for a NetFlow flow record and then display the result:

Defines transport matching criteria for a NetFlow flow record. |
|
To define transport matching criteria for a NetFlow flow record, use the match transport command. To remove the matching criteria, use the no form of this command.
match transport { destination-port | source-port }
no match transport { destination-port | source-port }
Flow Record configuration (config-flow-record)

To specify the maximum number of ports for a port profile, use the max-ports command. To remove the maximum ports configuration, use the no form of this command.
Number of ports for a port profile. The range is from 1 to 1024. |
Port profile configuration (config-port-prof)
|
|
This example shows how to set the maximum number of ports in the testprofile port profile:
n1000v#
configure terminal
This example shows how to remove the maximum ports configuration from the testprofile port profile:
n1000v#
configure terminal

Displays configuration information about a particular port profile. |
To create a new directory, use the mkdir command.
mkdir { bootflash: | debug: | volatile: }
|
|
This example shows how to create the bootflash: directory:
n1000v#
mkdir bootflash:

To enter commands on the Virtual Ethernet Module (VEM) remotely from the Cisco Nexus 1000V, use the module vem command.
module vem module-number execute line [ line ]
|
|
This example shows how to display the VEM port profile configuration remotely from the Cisco Nexus 1000V:
n1000v#
module vem 3 execute vemcmd show port-profile

To move a file from one directory to another, use the move command.
move [ filesystem : [ // module / ] [ directory / ] | directory / ] source-filename {{ filesystem : [ // module / ] [ directory / ] | directory / } [ destination-filename ] | target-filename }
The default name for the destination file is the same as the source filename.
|
|
You can make a copy of a file by using the copy command.
Tip You can rename a file by moving it within the same directory.
