service-port {inside | outside} default-action {drop | forward}

network-admin
Command History
|
|
4.0(4)SV1(2) |
This command was introduced. |
Usage Guidelines
If a port profile without a service port is configured on an SVM, it will flood the network with packets.
When configuring a port profile on an SVM, first bring the SVM down, This prevents a port-profile that is mistakenly configured without a service port from flooding the network with packets. The SVM can be returned to service after the configuration is complete and verified.
The service-port command is configurable only after the port-profile is configured for trunk mode and the virtual-service-domain has been configured.
Examples
This example shows how to configure an inside interface on a VSD port profile that drops packets if the service port is down:
n1000v# config t
n1000v(
config)# port-profile svm_vsd1_in
n1000v(
config-port-prof)# switchport mode trunk
n1000v(
config-port-prof)# virtual-service-domain test
n1000v(
config-port-prof)# service-port inside default-action drop
n1000v(
config-port-prof)#
This example shows how to remove a service port configuration:
n1000v# config t
n1000v(
config)# port-profile svm_vsd1_in
n1000v(
config-port-prof)# no service-port

Usage Guidelines
The Basic System Configuration Dialog assumes the factory defaults. Keep this in mind when using it to modify an existing configuration.
All changes made to your configuration are summarized for you at the completion of the setup sequence with an option to save the changes or not.
You can exit the setup sequence at any point by pressing Ctrl-C.
Examples
This example shows how to use the setup command to create or modify a basic system configuration:
n1000v# setup
Enter the domain id<1-4095>: 400

[########################################] 100%
---- Basic System Configuration Dialog ----
This setup utility will guide you through the basic configuration of
the system. Setup configures only enough connectivity for management
of the system.
*Note: setup is mainly used for configuring the system initially,
when no configuration is present. So setup always assumes system
defaults and not the current system configuration values.
Press Enter at anytime to skip a dialog. Use ctrl-c at anytime
to skip the remaining dialogs.

If you want to remove or replace an SSH server key, you must first disable the SSH server using the no ssh server enable command.
Examples
This example shows how to create an SSH server key using DSA:
n1000v# config t
n1000v(config)# ssh key dsa
generating dsa key(1024 bits).....
..
generated dsa key
This example shows how to create an SSH server key using RSA with the default key length:
n1000v# config t
n1000v(config)# ssh key rsa
generating rsa key(1024 bits).....
.
generated rsa key
This example shows how to create an SSH server key using RSA with a specified key length:
n1000v# config t
n1000v(config)# ssh key rsa 768
generating rsa key(768 bits).....
.
generated rsa key
This example shows how to replace an SSH server key using DSA with the force option:
n1000v# config t
n1000v(config)# no ssh server enable
n1000v(config)# ssh key dsa force
deleting old dsa key.....
generating dsa key(1024 bits).....
.
generated dsa key
n1000v(config)# ssh server enable
This example shows how to remove the DSA SSH server key:
n1000v# config t
n1000v(config)# no ssh server enable
XML interface to system may become unavailable since ssh is disabled
n1000v(config)# no ssh key dsa
n1000v(config)# ssh server enable
This example shows how to remove all SSH server keys:
n1000v# config t
n1000v(config)# no ssh server enable
XML interface to system may become unavailable since ssh is disabled
n1000v(config)# no ssh key

Usage Guidelines
Use this command to identify the port channel as being in vPC-HM, which requires traffic to be managed separately for each upstream switch connected to the member ports. If the upstream switches have CDP enabled, the Cisco Nexus 1000V can use this information to automatically assign subgroups. If the upstream swiches do not have CDP enabled, then you must configure subgroups manually.
This command overrides any subgroup configuration specified in the port-profile inherited by the port channel interface.
Examples
This example shows how to configure a subgroup type for a port channel interface:

–The virtual Ethernet interfaces on the destination VEM are brought into service.
•When licenses are successfully transferred from a VEM to the VSM license pool, then the following happens:
–The virtual Ethernet interfaces on the source VEM are removed from service.
Examples

Usage Guidelines
Volatile licenses are removed from a VEM during a loss in connectivity and are not returned to the VEM when connectivity resumes. Cisco recommends that the volatile license feature remain disabled and that you, instead, transfer unused licenses using the svs license transfer src-vem command.
Examples
This example shows how to enable the volatile license feature for a VSM:
n1000v(config)# svs license volatile
n1000v(config)#
This example shows how to disable the volatile license feature for a VSM:

system jumbomtu
To configure a system-wide jumbo frame size, specifying the maximum frame size that Ethernet ports can process, use the system jumbomtu command.
system jumbomtu size
Syntax Description
size |
Size, in bytes, of the Layer 2 Ethernet interface jumbo maximum transmission unit (MTU). Frames larger than this are dropped. The setting must be an even number between 1500 and 9000 bytes. |
Defaults
9000 bytes
Command Modes
Global configuration (config)
network-admin
Command History
|
|
4.0(4)SV1(1) |
This command was introduced. |
Usage Guidelines
•For transmissions to occur between two ports, you must configure the same MTU size for both ports.
•A port drops any frames that exceed its MTU size.
•If you do not configure a system jumbo MTU size, it defaults to 1500 bytes.
•For a Layer 2 port, you can configure an MTU size as the system default of 1500 bytes or the system default jumbo MTU size of 9000 bytes.
•If you change the system jumbo MTU size, Layer 2 ports automatically use the system default MTU size of 1500 bytes unless you specifically configure the MTU size differently per port.
Examples
This example shows how to configure a system-wide maximum frame size of 8000 bytes:
n1000v# config t
n1000v(config)# system jumbomtu 8000
n1000v#
Related Commands
system mtu
To override any maximum transmission unit (MTU) setting that has already been set on the uplink using the mtu command on the interface, use the system mtu command. To reset the switch to the default of 1500 for all the ports inheriting this system profile, use the no form of this command.
system mtu size
no system mtu
Syntax Description
size |
Size, in bytes, of the Layer 2 Ethernet interface maximum transmission unit (MTU). The range is 1500 to 9000, even numbers only. |
Defaults
1500 bytes
Command Modes

network-admin
Command History
|
|
4.0(4)SV1(3) |
This command was introduced. |
Usage Guidelines
The system mtu command is only applicable, and the configuration is only effective, for system uplink profiles. The value that is configured for system mtu command must be less then value configured in the system jumbomtu command.
Configuring the system MTU value on the system port-profile causes the interface inheriting this port-profile to flap. If the system port-profile includes the control VLAN, then the module, itself, will flap.
Examples
This en1000vxample shows how to configure the system MTU value as 3000 bytes for the system uplink profile called PP1:
n1000v# config t
n1000v(config-port-prof)# port-profile PP1
n1000v# system mtu 3000
n1000v#
