Limitations of Aruba CX Switch in Aruba Central
There are a few limitations while managing and monitoring Aruba CX switches using Aruba Central. The following sections provide details on the limitations while onboarding, configuring, monitoring, and troubleshooting Aruba CX switches using Aruba Central.
Onboarding
The following limitations should be taken into consideration when onboarding Aruba CX switches in Aruba Central:
ZTPZero Touch Provisioning. ZTP is a device provisioning mechanism that allows automatic and quick provisioning of devices with a minimal or at times no manual intervention. does not work on inline data ports for Aruba CX 8320 and 8325 switch series. The following is an example configuration for onboarding Aruba CX 8320 and 8325 switch series to Aruba Central:
interface 1/1/1
no shutdown
no routing
interface vlan 1
ip address <IP-ADDRESS/MASK>
ip route 0.0.0.0/0 <IP-GATEWAY>
ip dns server-address <DNS-SERVER>
https-server vrf default
ztp force-provision
After the erase startup-config command is executed on the Aruba CX switches, the switches do not onboard to Aruba Central. It is recommended to execute the erase all zeroize command, instead of the erase startup-config command.
When an Aruba CX switch is first onboarded to Aruba Central, Aruba Central must perform the following actions, before it can perform events such as rebooting the switch and upgrading the firmware:
Login to the switch using the password provided in the template configuration
Apply the template to the switch
Only DHCPDynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network. -based ZTP is supported on Aruba Central (on-premises) for CX. Activate-based ZTP is not supported.
FQDNFully Qualified Domain Name. FQDN is a complete domain name that identifies a computer or host on the Internet. or hostname for Aruba Central (on-premises) server is not supported. You must provide only the IP address.
The Aruba Central (on-premises) URIUniform Resource Identifier. URI identifies the name and the location of a resource in a uniform format. that is received as part of DHCP option is not persistent across reboots. You must include the Aruba Central (on-premises) URI configuration when applying the template configuration to avoid connectivity issues after initial onboarding using the DHCP option.
Applying Template
The following limitations should be taken into consideration when applying the template to Aruba CX switches in Aruba Central:
You must configure the admin password in the template configuration only in plaintext. The format of the password configuration command must be user admin group administrators password plaintext <string>.
If the template for Aruba CX switches contains %
in the configuration, Aruba Central will not save the configuration.
Although the %
character is allowed in Aruba CX switches, for example in banners, the same is not allowed in Aruba Central. In Aruba Central, the %
character is reserved for variables.
The maximum number of lines supported in the configuration template is 84000. Beyond this limit, Aruba Central will not apply the template to the Aruba CX switch.
The Aruba CX switches on the window. When initially onboarding an Aruba CX switch to Aruba Central, you must manually create the template for the switch
by using the output of the show running-config
command.
Configuring Aruba CX VSF Stack
The following are the VSF stacking limitations of Aruba CX switches in Aruba Central:
Aruba Central supports only a few functions related to Aruba CX switch stack, such as onboarding a stack to Aruba Central and replacing member switches having the same model and part number, through template configuration. All other stacking related functions, such as creating a stack, deleting, or adding a new member to the stack, must be performed offline, that is, outside Aruba Central. These stacking related functions must be performed before or after onboarding the stack to Aruba Central depending on the function.
For example, you must create a stack offline before onboarding the stack to Aruba Central. For more information, see Aruba CX VSF Stack.
Aruba CX VSF Stack Related Functions Not Supported on Aruba Central
The following stack related functions are not supported on Aruba Central:
Creating a new stack
Adding a new member to an existing stack
Deleting a member from the stack
Replacing a member with different part number
Modifying standby member ID
Adding, deleting, and modifying VSF links
Using Aruba CX VSX
The following limitations apply when configuring VSX or viewing VSX data for Aruba CX switches in Aruba Central:
Enabling VSX synchronization using template configuration in Aruba Central is not recommended. By enabling VSX synchronization, the peer switch might get into an unknown configuration state.
Last synced data is not displayed on the Aruba Central, if VSX synchronization is not enabled.
page, inManaging Firmware Upgrade
To upgrade an Aruba CX switch in Aruba Central, a WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. connection with a minimum speed of 2 MbpsMegabits per second is required. The upgrade activity will time out after a period of 60 minutes.
Uploading Aruba CX switch images to Aruba Central (on-premises) server for firmware upgrade fails.
Troubleshooting
The following are the limitations while troubleshooting Aruba CX switches in Aruba Central:
For Aruba CX 8320 and 8325 switch series, to use the remote console feature, you must enable SSHSecure Shell. SSH is a network protocol that provides secure access to a remote device. server on the VRFVisualRF. VRF is an AirWave Management Platform (AMP) module that provides a real-time, network-wide views of your entire Radio Frequency environment along with floor plan editing capabilities. VRF also includes overlays on client health to help diagnose issues related to clients, floor plan, or a specific location. that the switch uses to connect to Aruba Central. You must add one of the following commands in the template:
If the switch is connecting to Aruba Central using the inline default VRF, add ssh server vrf default to the template.
If the switch is connecting to Aruba Central using the OOBM management VRF, add ssh server vrf mgmt to the template.
The Aruba CX 8320 and 8325 switch series.

In the monitoring pages in Aruba Central, the IP address for the connected wired clients on Aruba CX switches might not be displayed. For more information, see Viewing the Clients > Clients Tab.
