Overview of ICX Switch Management

Preparing ICX Devices to be Managed by SmartZone

ICX devices can be managed by SmartZone. The following items are required to manage ICX devices:

• The SmartZone IP address must be reachable by the ICX device through the Management interface or through switch or router interfaces.
• The ICX device must be made aware of the configured SmartZone IP address in one of the following ways:
  • Configure the DHCP server to use DHCP option 43.
  • Issue the following command at the global configuration level:

    ICX(conf)# manager active-list SmartZone_Controller_IP_Address
     

  • Add an entry in the DNS server with the hostname ruckuscontroller or ruckuscontroller.local domain that points to the SmartZone IP address.
• On ICX 7750 devices, self-signed certificates are used. SmartZone honors these certificates when the non-tpm-switch-cert-validate command is entered on the SmartZone console, as shown in the following example. To check the configuration status of the tpm-switch-cert validation, enter the show running-config non-tpm-switch-cert-validate command.

  SZ# config 
  SZ(config)# non-tpm-switch-cert-validate
  Successful operation
  
  SZ(config)# end
  SZ# show running-config non-tpm-switch-cert-validate
  NonTPM Switch Certificate Validate: Enabled

• When SmartZone or ICX devices are behind network address translation (NAT), be sure to forward TCP ports 443 and 22 through NAT.
• Virtual platform requirements for supporting ICX devices are listed in the following table.
  Note: Each unit in a stack is considered a separate switch unit for capacity management purposes.

  Virtual Platform Requirements for Supporting ICX Devices

  Platform	Maximum Number of Switches Per Node	RAM	vCPU	Disk Storage
  vSZ-E	200	18 GB	4	100 GB
  vSZ-H	2000	30 GB	12	300 GB

  The scaling limits in the table apply to switch-only deployments. For a mix of APs and switches, the scaling limits vary accordingly. SmartZone supports a 5-to-1 AP-to-switch ratio.

  vSZ-E Example: vSZ-E supports up to 1,000 APs on a single node. If 200 APs are currently managed by SmartZone, there is room for 800 more APs or 160 ICX switches (800 divided by 5).

  vSZ-H Example: vSZ-H supports up to 2,000 ICX switches on a single node. If 500 switches are currently managed, there is room for 1,500 more switches, or 7,500 APs (1500 multiplied by 5).
