Limitations of AOS-CX Switch in Aruba Central

There are a few limitations while managing and monitoring AOS-CX switches using Aruba Central (on-premises). The following sections provide details on the limitations while onboarding, configuring, monitoring, and troubleshooting AOS-CX switches using Aruba Central (on-premises).

Onboarding

The following limitations should be taken into consideration when onboarding AOS-CX switches in Aruba Central (on-premises):

• 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 AOS-CX 8320 and 8325 switch series. The following is an example configuration for onboarding AOS-CX 8320 and 8325 switch series to Aruba Central (on-premises):
  interface 1/1/1 no shutdown no routing interface vlanVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. 1 ip address <IP-ADDRESS/MASK> ip route 0.0.0.0/0 <IP-GATEWAY> ip dns server-address <DNSDomain Name System. A DNS server functions as a phone book for the intranet and Internet users. It converts human-readable computer host names into IP addresses and IP addresses into host names. It stores several records for a domain name such as an address 'A' record, name server (NS), and mail exchanger (MX) records. The Address 'A' record is the most important record that is stored in a DNS server, because it provides the required IP address for a network peripheral or element.-SERVER> https-server vrf default ztp force-provision
• After the erase startup-config command is executed on the AOS-CX switches, the switches do not onboard to Aruba Central (on-premises). It is recommended to execute the erase all zeroize command, instead of the erase startup-config command.
• When an AOS-CX switch is first onboarded to Aruba Central (on-premises), Aruba Central (on-premises) 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 AOS-CX. Activate-based ZTP is not supported.
• Pre-shared key (PSKPre-shared key. A unique shared secret that was previously shared between two parties by using a secure channel. This is used with WPA security, which requires the owner of a network to provide a passphrase to users for network access. )-based onboarding of AOS-CX switches is not supported on Aruba Central (on-premises).
• 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 AOS-CX switches in Aruba Central (on-premises):

• 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 AOS-CX switches contains % in the configuration, Aruba Central (on-premises) will not save the configuration.
• Although the % character is allowed in AOS-CX switches, for example in banners, the same is not allowed in Aruba Central (on-premises). In Aruba Central (on-premises), the % character is reserved for variables.
• The maximum number of lines supported in the configurAOS-CX switch.
• When onboarding an AOS-CX switch with 10.05 firmware to Aruba Central (on-premises), using the Import Configuration as Template option on the Add Template window displays an error message and does not import the configuration. You must manually create the template for the switch using the output of the show running-config command. You can successfully import the configuration as template for an AOS-CX switch with 10.05 firmware, only when the switch is part of a template group and the config-sync status is in-sync. To import the configuration as template when onboarding an AOS-CX switch, without the error message, you can upgrade the switch to 10.06 firmware.

Configuring AOS-CX VSF Stack

The following are the VSF stacking limitations of AOS-CX switches in Aruba Central (on-premises):

Aruba Central (on-premises) supports only a few functions related to Aruba CX switch stack, such as onboarding a stack to Aruba Central (on-premises) 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 (on-premises). These stacking related functions must be performed before or after onboarding the stack to Aruba Central (on-premises) depending on the function.

For example, you must create a stack offline before onboarding the stack to Aruba Central (on-premises). For more information, see AOS-CX VSF Stack.

AOS-CX VSF Stack Related Functions Not Supported on Aruba Central (on-premises)

The following stack related functions are not supported on Aruba Central (on-premises):

• 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 AOS-CX VSX

The following limitations apply when configuring VSX or viewing VSX data for AOS-CX switches in Aruba Central (on-premises):

• Enabling VSX synchronization using template configuration in Aruba Central (on-premises) 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 VSX page, in Aruba Central (on-premises), if VSX synchronization is not enabled.

Managing Firmware Upgrade

• To upgrade an AOS-CX switch in Aruba Central (on-premises), 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 AOS-CX switch images to Aruba Central (on-premises) server for firmware upgrade fails.

Troubleshooting

The following are the limitations while troubleshooting AOS-CX switches in Aruba Central (on-premises):

• For AOS-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 (on-premises). You must add one of the following commands in the template:
  • If the switch is connecting to Aruba Central (on-premises) using the inline default VRF, add ssh server vrf default to the template.
  • If the switch is connecting to Aruba Central (on-premises) using the OOBM management VRF, add ssh server vrf mgmt to the template.
• The Chassis Locate option, in the Analyze > Tools > Device Check tab, is not displayed for AOS-CX 8320 and 8325 switch series.

Monitoring

In the monitoring pages in Aruba Central (on-premises), the IP address for the connected wired clients on AOS-CX switches might not be displayed. For more information, see Switch > Clients > Clients.
