Command History


Release	Modification
4.0(1a)N2(1)	This command was introduced.

Usage Guidelines

When you provision the Fabric Extender using the statically pinned mode (see the Cisco Nexus 2000 Series Fabric Extender Software Configuration Guide, the host interfaces on the Fabric Extender are pinned to the fabric interfaces in the order that they were initially configured. The next time that you reboot the Fabric Extender, the configured fabric interfaces are pinned to the host interfaces in an ascending order by the port number of the fabric interface.

Use the fex pinning redistribute command if you want to configure the same fixed distribution of host interfaces without restarting the Fabric Extender after your initial configuration.

Caution

This command disrupts all the host interface ports of the Fabric Extender. However, the disruption is shorter than would be the case if you reboot the Fabric Extender.

Examples

This example shows how to redistribute the host interfaces on a Fabric Extender:

switch# fex pinning redistribute 101

switch#

Command History


Release	Modification
4.2(1)N1(1)	This command was introduced.

Usage Guidelines

By default, the drop threshold applies to each Fabric Extender port to limit the amount of buffer being allocated for each port. To restore the default queue limit of each Fabric Extender port, use the fex queue-limit command.

Examples

This example shows how to set the queue limit for the input buffer for each Fabric Extender port:

switch(config)# system qos

switch(config-sys-qos)# fex queue-limit

switch(config-sys-qos)#

This example shows how to restore the default queue limit for each Fabric Extender port:

switch(config)# system qos

switch(config-sys-qos)# no fex queue-limit

switch(config-sys-qos)#

Related Commands


Command	Description
show fex	Displays all configured Fabric Extender chassis connected to the switch.

hardware buffer-threshold

To limit the amount of input hardware buffer usage for each Fabric Extender, use the hardware buffer-threshold command. To revert to the default and allow a Fabric Extender to use all available hardware buffer space, use the no form of this command.

hardware fex_card_typ buffer-threshold buffer-limit

no hardware fex_card_typ buffer-threshold

Command Default

None

Command Modes

Fabric extender configuration mode

Command History


Release	Modification
4.2(1)N2(1)	This command was introduced.

Usage Guidelines

You can use a lower queue limit value on the Fabric Extender to prevent one blocked receiver from affecting traffic being sent to other noncongested receivers ("head-of-line blocking"); however, this will increase burst absorption on the ingress traffic. A higher queue limit value provides better burst absorption and less head-of-line blocking protection.

Command History


Release	Modification
4.0(1a)N2(1)	This command was introduced.
4.2(1)N1(1)	The number of uplinks is extended to 8.

Usage Guidelines

Use the pinning max-links command when you create a number of pinned fabric interface connections to enable the parent switch to determine a distribution of host interfaces. The host interfaces are divided by the number of uplinks and distributed accordingly.

Caution

Changing the value of uplinks is disruptive. All the host interfaces on the Fabric Extender are brought down and back up as the parent switch reassigns its static pinning.

Examples

This example shows how to specify the number of statically pinned uplinks for a Fabric Extender:

switch# configure terminal 
switch(config)# fex 101 
switch(config-fex)# pinning max-links 4

This example shows how to revert to the uplink count to the default for a Fabric Extender:

switch# configure terminal 
switch(config)# fex 101 
switch(config-fex)# no pinning max-links

Command History


Release	Modification
4.0(1a)N2(1)	This command was introduced.

Usage Guidelines

The serial number string you define with the serial command must match the serial number of the Fabric Extender. If you configure a serial number and then you use the fex associate command to associate the corresponding chassis ID to the switch, the association will succeed only if the Fabric Extender reports a matching serial number string.

Caution

Configuring a serial number other than that of the given Fabric Extender will force the Fabric Extender offline.

Examples

This example shows how to specify a serial number for a Fabric Extender:

switch# configure terminal 
switch(config)# fex 101 
switch(config-fex)# serial Rack16_FEX101
