rate-mode dedicated

To set the dedicated rate mode for the specified ports, use the rate-mode dedicated command.

rate-mode dedicated

no rate-mode

Syntax Description

This command has no arguments or keywords.

Command Default

Shared rate mode is the default.

Command Modes

Interface configuration mode

Command History

Release

Modification

4.0

This command was introduced.

Usage Guidelines

Use the rate-mode dedicated command to set the dedicated rate mode for the specified ports.

On a 32-port,10-Gigabit Ethernet module, each set of four ports can handle 10 gigabits per second (Gb/s) of bandwidth. You can use the rate-mode parameter to dedicate that bandwidth to the first port in the set of four ports or share the bandwidth across all four ports.


Note
When you dedicate the bandwidth to one port, you must first administratively shut down the ports in the group, change the rate mode to dedicated, and then bring the dedicated port administratively up.

Table 1 identifies the ports that are grouped together to share each 10 Gb/s of bandwidth and which port in the group can be dedicated to utilize the entire bandwidth.

Note
All ports in each port group must be part of the same virtual device context (VDC). For more information on VDCs, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide, Release 5.x.

When you enter the rate-mode dedicated command, the full bandwidth of 10 Gbps is dedicated to one port. When you dedicate the bandwidth, all subsequent commands for the port are for dedicated mode.

This command does not require a license.

Examples

This example shows how to configure the dedicated rate mode for Ethernet ports 4/17, 4/19, 4/21, and 4/23: 

switch# configure terminal
switch(config)# interface ethernet 4/17, ethernet 4/19, ethernet 4/21, ethernet 4/23
switch(config-if)# shutdown
switch(config-if)# interface ethernet 4/17
switch(config-if)# rate-mode dedicated
switch(config-if)# no shutdown

Command

Description

show interface

Displays interface information, which includes the current rate mode dedicated.

rate-mode shared

To set the shared rate mode for the specified ports, use the rate-mode shared command.

rate-mode shared

Syntax Description

This command has no arguments or keywords.

Command Default

Shared rate mode is the default.

Command Modes

Interface configuration mode

Command History

Release

Modification

4.0

This command was introduced.

Usage Guidelines

Use the rate-mode shared command to set the shared rate mode for the specified ports. This is the default rate mode for the module.

That is, use the rate-mode shared command to specify that each 10 Gbps of bandwidth on a 32-port 10-Gigabit Ethernet module is shared by ports in the same port group.

If the port group is in dedicated rate mode, you must first administratively shut down the ports in the group, change the rate mode to shared, and then bring the ports administratively up.

This command does not require a license.

Examples

This example shows how to configure the shared rate mode for Ethernet ports 4/17, 4/19, 4/21, and 4/23: 

switch# configure terminal
switch(config)# interface ethernet 4/17, ethernet 4/19, ethernet 4/21, ethernet 4/23
switch(config-if)# shutdown
switch(config-if)# interface ethernet 4/17
switch(config-if)# rate-mode shared
switch(config-if)# no shutdown

reload restore

To configure a virtual port channel (vPC) device to assume that its peer is not functional and to bring up the vPC, use the reload restore command. To reset the vPC to the standard behavior, use the no form of this command.

reload restore [delay time-out]

no reload restore

Syntax Description

delay time-out

(Optional) Sets the timeout for the vPC device. The range is from 240 to 3600.

Command Default

Delay of 240 seconds

Command Modes

vPC domain configuration mode

Command History

Release

Usage Guidelines

This command does not require a license.

Examples

This example shows how to configure a vPC device to assume that its peer is not functional and to bring up the vPC: 

switch(config)# vpc domain 5
switch(config-vpc-domain)# reload restore
Warning: Enables restoring of vPCs in a peer-detached state after reload, will wait for 240 sec (by default) to determine if peer is un-reachable

Command

Description

vpc domain

Creates a virtual port-channel (vPC) domain.

remote-loopback disable

To perform no action on an interface when a remote-loopback event occurs, use the remote-loopback disable command in Ethernet OAM action configuration mode or interface Ethernet OAM action configuration mode. To remove the configuration, use the no form of this command.

remote-loopback {disable | log}

noremote-loopback {disable | log}

Syntax Description

disable

Performs no action on the interface when a remote-loopback event occurs.

log

(Interface Ethernet OAM action configuration only) Creates a syslog entry when a remoteloopback event occurs. This action is available in Interface Ethernet OAM action configuration mode to override the profile setting and log the event for the interface when it occurs.

Command Default

The default action is to create a syslog entry.

Examples

The following example shows how to configure that no action is performed on the interface when a remote-loopback event occurs: 

switch# configure terminal
switch(config)# ethernet oam profile Profile_1
switch(config-eoam)# action
switch(config-eoam-action)# remote-loopback disable

Modification

4.1(3)

This command was introduced.

Usage Guidelines

You must enable the vPC feature before you can create a vPC system priority

By default, the system elects a primary and secondary vPC peer device after you configure the vPC domain and both sides of the vPC peer link. However, you may want the system to elect a specific vPC peer device as the primary device for the vPC. Then, you would manually configure the role value for the vPC peer device that you want as primary to be lower than that of the other vPC peer device.

This command does not require a license.

Examples

This example shows how to create a vPC role priority: 

switch# configure terminal
switch(config)# vpc domain 5
switch(config-vpc-domain)# role priority 2000
