Before you can associate an interface on the parent switch to the Fabric Extender, you must first make the interface into a fabric interface by entering the switchport mode fex-fabric command.
Note On a Cisco Nexus 5000 Series switch that runs a Cisco NX-OS release 4.2(1)N1(1), the switchport mode fex-fabric command is not supported on an Ethernet interface.
This example shows how to associate the Fabric Extender to an Ethernet interface:
switch# configure terminal
switch(config)# interface ethernet 1/40
switch(config-if)# switchport mode fex-fabric
switch(config-if)# fex associate 101
This example shows how to associate the Fabric Extender to an EtherChannel interface:
switch# configure terminal
switch(config)# interface port-channel 4
switch(config-if)# switchport mode fex-fabric
switch(config-if)# fex associate 101
|
|
---|---|
show fex |

chassis_ID |
Fabric Extender chassis ID. The chassis ID range is from 100 to 199. |
None
EXEC mode
|
|
4.0(1a)N2(1) |
This command was introduced. |
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.
This example shows how to redistribute the host interfaces on a Fabric Extender:
switch#
fex pinning redistribute 101
switch#
To limit the amount of input buffer space (in bytes) allocated to each Fabric Extender port, use the fex queue-limit command. To disable the drop threshold and allow a Fabric Extender port to use all available buffer space, use the no form of this command.
fex queue-limit
no fex queue-limit
This command has no arguments or keywords.
Fabric Extender queue limit is available in the default configuration and is set on.
System QoS configuration mode
|
|
---|---|
4.2(1)N1(1) |
This command was introduced. |
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.
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)#
|
|
---|---|
show fex |
Displays all configured Fabric Extender chassis connected to the switch. |
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
None
Fabric extender configuration mode
|
|
---|---|
4.2(1)N2(1) |
This command was introduced. |
The buffer-threshold keyword sets the consumption level of input buffers before an indication is sent to the egress queue to start observing the tail drop threshold. If the buffer usage is lower than the configured buffer threshold, the tail drop threshold is ignored.
Supported Cisco Nexus 2000 Series Fabric Extender
The following Cisco Nexus 2000 Series Fabric Extenders are supported on a Cisco Nexus 5000 Series switch that runs a Cisco NX-OS release 4.2(1)N2(1):
•Cisco Nexus 2148T Fabric Extender—It has four 10-Gigabit Ethernet fabric interfaces for its uplink connection to the parent Cisco Nexus 5000 Series switch and 48 1000BASE-T (1-Gigabit) Ethernet host interfaces for its downlink connection to servers or hosts.
•Cisco Nexus N2224TP Fabric Extender—It has two 10-Gigabit Ethernet fabric interfaces with small form-factor pluggable (SFP+) interface adapters for its uplink connection to the parent Cisco Nexus 5000 Series switch and 24 1000BASE-T (1-Gigabit) Ethernet host interfaces for its downlink connection to servers or hosts. It does not support Fibre Channel over Ethernet (FCoE).
•Cisco Nexus 2232P Fabric Extender—It has eight 10-Gigabit Ethernet fabric interfaces with small form-factor pluggable (SFP+) interface adapters for its uplink connection to the parent Cisco Nexus 5000 Series switch and 32 10-Gigabit Ethernet fabric interfaces with SFP+ interface adapters for its downlink connection to servers or hosts.
•Cisco Nexus 2248T Fabric Extender—It has four 10-Gigabit Ethernet fabric interfaces with SFP+ interface adapters for its uplink connection to the parent Cisco Nexus 5000 Series switch and 48 1000BASE-T (1-Gigabit) Ethernet host interfaces for its downlink connection to servers or hosts.
Note This command is available only on a Cisco Nexus 2148T Fabric Extender.
This example shows how to configure the hardware buffer threshold limit on a Cisco Nexus 2148T Fabric Extender:
switch(config)# fex 110
switch(config-fex)# hardware N2148T buffer-threshold 163840
switch(config-fex)#
This example shows how to remove the hardware buffer threshold configured on a Cisco Nexus 2148T Fabric Extender:
switch(config)# fex 110
switch(config-fex)# no hardware N2148T buffer-threshold
switch(config-fex)#
To control the egress queue tail drop threshold level on a Fabric Extender, use the hardware queue-limit command. To disable the drop threshold and allow a Fabric Extender to use all available hardware buffer space, use the no form of this command.
hardware fex_card_typ queue-limit [queue-limit]
no hardware fex_card_typ queue-limit
None
Fabric extender configuration mode
|
|
---|---|
4.2(1)N2(1) |
This command was introduced. |
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.
