Manage interfaces
In theInterfacespane, you can display the mapping of the virtual interfaces on the VPX instances to the SDX appliance, and assign MAC addresses to the interfaces.
Note:Autonegotiation is not supported on an interface to which a direct attach cable (DAC) is connected.
In the list of Interfaces in theInterfacespane, in theStatecolumn, UP indicates that the interface is receiving traffic normally. DOWN indicates a network issue because of which the interface is unable to send or receive traffic.
Important:Flow control is not recommended from connections over 1 GB.
To configure an interface
On the配置tab, in the navigation pane, expandSystem, and then clickInterfaces.
In theInterfacespane, click the interface that you want to configure, and then clickEdit.
In theConfigure Interfacewindow, specify values for the following parameters:
- Auto Negotiation— Enable auto-negotiation. Possible values: ON, OFF. Default: ON.
- Speed— Ethernet speed for the interface, in Mb/s. Possible values: 10, 100, 1000, and 10000.
- Duplex—Type of duplex operation of the interface. Possible values: Full, Half, NONE. Default: NONE.
- Flow Control Auto Negotiation— Automatically negotiate flow control parameters. Possible values: ON, OFF. Default: ON
- Rx Flow Control— Enable Rx flow control. Possible values: ON, OFF. Default: ON
- Tx Flow Control— Enable Tx flow control. Possible values: ON, OFF. Default: ON
ClickOK, and then clickClose.
To reset the parameters of an interface to their default values
- On the配置tab, in the navigation pane, expandSystem, and then clickInterfaces.
- In theInterfacespane, click the interface that you want to reset, and then clickReset.
Display the mapping of virtual interfaces on the VPX instance to the physical interfaces
In the NetScaler VPX instance, the GUI and the CLI display the mapping of the virtual interfaces on the instance to the physical interfaces on the appliance.
After logging on to the VPX instance, in the configuration utility, navigate toNetwork, and then clickInterfaces.The virtual interface number on the instance and the corresponding physical interface number on the appliance appear in theDescriptionfield, as shown in the following figure:
In the CLI, type theshow interface
command. For example:
> show interface 1) Interface 10/3 (10G VF Interface, PF 10/4) #2 flags=0xe460 MTU=1500, native vlan=1, MAC=6e:b6:f5:21:5d:db, uptime 43h03m35s Actual: media FIBER, speed 10000, duplex FULL, fctl NONE, throughput 10000 RX: Pkts(2547925) Bytes(287996153) Errs(0) Drops(527183) Stalls(0) TX: Pkts(196) Bytes(8532) Errs(0) Drops(0) Stalls(0) NIC: InDisc(0) OutDisc(0) Fctls(0) Stalls(0) Hangs(0) Muted(0) Bandwidth thresholds are not set. ...
Assigning a MAC address to an interface
While you are provisioning an ADC instance on an SDX appliance, the Citrix Hypervisor internally assigns a MAC address to a virtual interface associated with that instance. The same MAC address might be assigned to a virtual interface associated with another instance on the same appliance or on another appliance. To prevent the assignment of duplicate MAC addresses, you can enforce unique MAC addresses.
There are two ways of assigning a MAC address to an interface:
- Assign a base MAC address and a range to an interface: The Management Service assigns a unique MAC address by using the base address and range.
- Assign a global base MAC address: A global base MAC address applies to all interfaces. The Management Service then generates the MAC addresses for all interfaces. If you set the global base MAC address, the range for a 1G interface is set to 8. The range for a 10G interface is set to 64. See the following table for sample base MAC addresses if the global base MAC address is set to 00:00:00:00:00:00.
Physical Interface | Base MAC Address |
---|---|
0/1 | 00:00:00:00:00:00 |
0/2 | 00:00:00:00:00:08 |
1/1 | 00:00:00:00:00:10 |
1/2 | 00:00:00:00:00:18 |
1/3 | 00:00:00:00:00:20 |
1/4 | 00:00:00:00:00:28 |
1/5 | 00:00:00:00:00:30 |
1/6 | 00:00:00:00:00:38 |
1/7 | 00:00:00:00:00:40 |
1/8 | 00:00:00:00:00:48 |
10/1 | 00:00:00:00:00:50 |
10/2 | 00:00:00:00:00:90 |
Table 1. Example of Base MAC Addresses Generated from a Global Base MAC Address
The base MAC address for the management ports is for reference only. The Management Service generates MAC addresses, based on the base MAC address, for 1/x and 10/x ports only.
Note: You cannot assign a base MAC address to a channel.
To perform the various operations with MAC address, clickSystem > Interfaces. Select an interface and then clickEdit. Perform the MAC address operation, in theConfigure Interfacewindow.
Disable or enable the physical interfaces on the SDX appliance
If you are not using any of the physical interfaces on the SDX appliance, you can disable the physical interface using the Management Service. This action is helpful for security purposes.
Note: By default, all the physical interfaces on the SDX appliance are enabled. Also, if an interface is used by a VPX or channel, you cannot disable the interface.
To disable the physical interface:
- On the配置tab, in the navigation pane, expandSystem, and then clickInterfaces.
- In theInterfacespane, select the interface that you want to disable.
- In theActiondrop-down list, clickDisable.
If you want to use the disabled physical interface, you can enable the interface using the Management Service.
To enable the disabled physical interface:
- On the配置tab, in the navigation pane, expandSystem, and then clickInterfaces.
- In theInterfacespane, select the disable interface that you want to enable.
- In theActiondrop-down list, clickEnable.
