O Commands

This chapter describes the Cisco NX-OS security commands that begin with O.

object-group ip address

To define an IPv4 address object group or to enter object-group configuration mode for a specific IPv4-address object group, use the object-group ip address command. To remove an IPv4-address object group, use the no form of this command.

object-group ip address name

no object-group ip address name

 
Syntax Description

name

Name of the IPv4 address object group, which can be up to 64 alphanumeric, case-sensitive characters.

 
Defaults

None

 
Command Modes

Global configuration

 
Command History

Release
Modification

7.3(0)N1(1)

This command was introduced.

 
Usage Guidelines

You can use IPv4 object groups in permit and deny commands for IPv4 access control lists (ACLs).

IPv4 address object groups are not directional. Whether group members match a source or destination address or whether an object group applies to inbound or outbound traffic depends upon how you use the object group in an IPv4 ACL.

This command does not require a license.

Examples

This example shows how to configure an IPv4 address object group named ipv4-addr-group-13 with two group members that are specific IPv4 addresses and one group member that is the 10.23.176.0 subnet:

switch# config t
switch(config)# object-group ip address ipv4-addr-group-13
switch(config-ipaddr-ogroup)# host 10.121.57.102
switch(config-ipaddr-ogroup)# 10.121.57.234/32
switch(config-ipaddr-ogroup)# 10.23.176.0 0.0.0.255
switch(config-ipaddr-ogroup)# show object-group ipv4-addr-group-13
10 host 10.121.57.102
20 host 10.121.57.234
30 10.23.176.0/24
switch(config-ipaddr-ogroup)#

Description

host (IPv4)

Configures a group member for an IPv4 address object group.

show object-group

Displays object groups.

object-group ip port

To define an IP port object group or to enter object-group configuration mode for a specific IP port object group, use the object-group ip port command. To remove an IP port object group, use the no form of this command.

object-group ip port name

no object-group ip port name

 
Syntax Description

name

Name of the IP port object group, which can be up to 64 alphanumeric, case-sensitive characters.

 
Defaults

None

 
Command Modes

Global configuration

 
Command History

Release
Modification

7.3(0)N1(1)

This command was introduced.

 
Usage Guidelines

You can use IP port object groups in permit and deny commands for IPv4 and IPv6 access control lists (ACLs).

IP port object groups are not directional. Whether group members match a source or destination port or whether an object group applies to inbound or outbound traffic depends upon how you use the object group in an ACL.

This command does not require a license.

Examples

This example shows how to configure an IP port object group named port-group-05 with a group member that matches traffic sent to or from port 443:

switch# config t
switch(config)# object-group ip port port-group-05
switch(config-port-ogroup)# eq 443
switch(config-port-ogroup)# show object-group port-group-05
10 eq 443
switch(config-port-ogroup)#

Command
Description

eq

Specifies an equal-to group member in an IP port object group.

gt

Specifies a greater-than group member in an IP port object group.

lt

Specifies a less-than group member in an IP port object group.

neq

Specifies a not-equal-to group member in an IP port object group.

range

Specifies a port range group member in an IP port object group.

show object-group

Displays object groups.

object-group ipv6 address

To define an IPv6 address object group or to enter IPv6 address object group configuration mode for a specific IPv6 address object group, use the object-group ipv6 address command. To remove an IPv6 address object group, use the no form of this command.

object-group ipv6 address name

no object-group ipv6 address name

 
Syntax Description

name

Name of the IPv6 address group object, which can be up to 64 alphanumeric, case-sensitive characters.

 
Defaults

None

 
Command Modes

Global configuration

 
Command History

Release
Modification

7.3(0)N1(1)

This command was introduced.

 
Usage Guidelines

You can use IPv6 object groups in permit and deny commands for IPv6 ACLs.

IPv6 address object groups are not directional. Whether group members match a source or destination address or whether an object group applies to inbound or outbound traffic depends upon how you use the object group in an IPv6 ACL.

This command does not require a license.

Examples

This example shows how to configure an IPv6 address object group named ipv6-addr-group-A7 with two group members that are specific IPv6 addresses and one group member that is the 2001:db8:0:3ab7:: subnet:

switch# config t
switch(config)# object-group ipv6 address ipv6-addr-group-A7
switch(config-ipv6addr-ogroup)# host 2001:db8:0:3ab0::1
switch(config-ipv6addr-ogroup)# 2001:db8:0:3ab0::2/128
switch(config-ipv6addr-ogroup)# 2001:db8:0:3ab7::/96
switch(config-ipv6addr-ogroup)# show object-group ipv6-addr-group-A7
10 host 2001:db8:0:3ab0::1
20 host 2001:db8:0:3ab0::2
30 2001:db8:0:3ab7::/96
switch(config-ipv6addr-ogroup)#
