Configure network interfaces

Network interfaces in the Citrix ADC appliance are numbered innotation. After configuring your interfaces, display the interfaces and their settings to verify the configuration. You can also display this information to troubleshoot a problem in the configuration.

来manage the network interfaces, you can do the following;

• Enable some interfaces and disable others.
• Reset an interface to renegotiate its settings.
• Clear the accumulated statistics for an interface.

来verify the configuration, you can display the interface settings. You can display the statistics for an interface to evaluate its health.

Set the network interface parameters

The network interface configuration is neither synchronized nor propagated. For an HA pair, you must perform the configuration on each unit independently.

来set the network interface parameters by using the CLI:

At the command prompt, type:

- set interface  [-speed ] [-duplex ] [-flowControl ] [-autoneg ( DISABLED | ENABLED )] [-haMonitor ( ON | OFF )] [ ( ON | OFF )] [-tagall ( ON | OFF )] [-lacpMode ] [-lacpKey] [-lacpPriority ] [-lacpTimeout (LONG | SHORT )] [-ifAlias ] [-throughput ][-bandwidthHigh  [-bandwidthNormal ]] - show interface [] 

Example:

> set interface 1/8 -duplex full Done 

来set the network interface parameters by using the GUI:

Navigate toSystem > Network > Interfaces, select the network interface that you want to modify (for example, 1/8), clickEdit, and then set the parameters.

Setting the receive ring size and ring type for an interface

You can increase the receive ring size and ring type for IX, F1X, F2X, or F4X interfaces on Citrix ADC MPX and SDX platforms.

An increased ring size provides more cushion to handle burst traffic, but might impact the performance. A ring size of up to 8192 is supported for IX interfaces. A ring size of up to 4096 is supported for F1X, F2X, and F4X interfaces. The default ring size remains 2048.

接口环类型默认是弹性的。他们increase or decrease in size based on packet arrival rate. You can configure the ring type as “fixed” in which case the ring size does not change based on traffic rate.

Note:This feature is supported from release 13.0 build 41.x, and supported on platforms that have IX, F1X, F2X, or F4X interfaces.

Use theshow hardwarecommand to identify whether your appliance has IX, F1X, F2X, or F4X interfaces.

Examples:

The following model has 16 F1X (10G) interfaces and 4 F4X (40G) interfaces.

来configure ring size and ring type by using the CLI At the command line, type:

set interface  -ringsize  -ringtype ( Elastic | Fixed ) 

Parameters:

ringsize:

The receive ring size of the interface. A higher number provides more buffers to handle incoming traffic.

Default value: 2048 Minimum value: 512 Maximum value: 16384

ringtype:

The receive ring type of the interface. A fixed ring type preallocates the configured number of buffers irrespective of traffic rate. In contrast, an elastic ring, expands and shrinks based on incoming traffic rate.

Possible values: Elastic, Fixed

Default value: Elastic

Example:

> set interface 40/2 -ringsize 4096 -ringtype Fixed Done > show interface 40/2 1) Interface 40/2 (40G Ethernet, CR4, 40 Gbit) #21 flags=0xc020  MTU=1500, native vlan=10, MAC=00:e0:ed:75:14:2a, uptime 119h26m32s Requested: media AUTO, speed AUTO, duplex AUTO, fctl OFF,throughput 0 Actual: media UTP, speed 40000, duplex FULL, fctl OFF, throughput 40000 LLDP Mode: NONE, LR Priority: 1024 RX: Pkts(1443972660032) Bytes(1457207315336105) Errs(0) Drops(53319) Stalls(0) TX: Pkts(1452311431262) Bytes(1458534011197761) Errs(0) Drops(788) Stalls(0) NIC: InDisc(0) OutDisc(0) Fctls(0) Stalls(0) Hangs(0) Muted(0) Bandwidth thresholds are not set.

The last line shows the configured and actual ring size, and the ring type.

来configure ring size and ring type by using the GUI:

1. Navigate toSystem > Network > Interfaces.
2. Select your interface and clickEdit.

3. InRing Size, specify one of the following:

   • IX interfaces:512, 1024, 2048, 4096, or 8192.

   • F1X, F2X, or F4X interfaces:512, 1024, 2048, or 4096.

4. InRing Type, select Elastic or Fixed.
5. ClickOK.

Enable and disable network interfaces

By default, the network interfaces are enabled. Disable any network interface that is not connected to the network, so that it cannot send or receive packets. Disabling a network interface that is connected to the network in a high availability setup can cause a failover.

For more information about high availability, seeHigh Availability.

来enable or disable a network interface by using the CLI:

At the command prompt, type:

- enable interface  - show interface  - disable interface  - show interface  

Example:

> enable interface 1/8 Done > show interface 1/8 Interface 1/8 (Gig Ethernet 10/100/1000 MBits) #2 flags=0x4004000  MTU=1514, MAC=00:d0:68:15:fd:3d, downtime 906h58m40s Requested: media UTP, speed AUTO, duplex FULL, fctl OFF, throughput 0 RX: Pkts(0) Bytes(0) Errs(0) Drops(0) Stalls(0) TX: Pkts(0) Bytes(0) Errs(0) Drops(0) Stalls(0) NIC: InDisc(0) OutDisc(0) Fctls(0) Stalls(0) Hangs(0) Muted(0) Bandwidth thresholds are not set. Done 

来enable or disable a network interface by using the GUI:

1. Navigate toSystem > Network > Interfaces.
2. Select the network interface and, in theActionlist, select Enable or Disable.

Reset network interfaces

Network interface settings control properties such as duplex and speed. To renegotiate the settings of a network interface, you must reset it.

来reset a network interface by using the CLI:

At the command prompt, type:

- reset interface  - show interface  

Example:

> reset interface 1/8 Done 

来reset a network interface by using the GUI:

1. Navigate toSystem > Network > Interfaces.
2. Select the network interface and, in theActionlist, selectReset Interface.

Monitor a network interface

You can display network interface statistics to monitor parameters and use the information to check the health of the network interface. You can monitor parameters, such as packets sent and packets received, throughput, Link Aggregate Control Protocol (LACP) data units, and errors. You can clear the statistics of a network interface to monitor its statistics from the time the statistics are cleared.
