sz passive

Configures the lowest priority SmartZone IP addresses that the ICX switch will use to initiate a connection with SmartZone.
Syntax
sz passive { ip-address } [ ip-address2 ] [ ip-address3 ]
no sz active
Command Default

SmartZone IP addresses are not configured on the switch, which means the switch will attempt to initiate a connection with SmartZone using the SmartZone IP addresses provided via DHCP Option 43.

Parameters
ip-address
The first of the back-up SmartZone IP address that the switch will attempt to connect with.
ip-address2
SmartZone IP address that the switch will attempt to connect with if the first back-up address doesn't work.
ip-address3
SmartZone IP address that the switch will attempt to connect with if the first two back-up addresses don't work.
Modes

Global configuration

Usage Guidelines

Use the no form of the sz passive command to remove the SmartZone IP addresses.

An ICX switch identifies SmartZone and initiates a connection based on the SmartZone IP addresses configured on the switch or discovered through DHCP Option 43.

Both "active" and "passive" SmartZone IP addresses can be configured on the ICX switch. Active IP addresses are given the highest priority; passive IP addresses are lowest priority and are provided for redundancy. The ICX switch will attempt to connect to SmartZone by sending a query to SmartZone IP addresses in the following order:

  • SmartZone IP addresses configured on the ICX switch using the sz active command
  • SmartZone IP addresses received through DHCP Option 43
  • Backup SmartZone IP addresses configured on the ICX switch using the sz passive command

If SmartZone IP addresses are configured on both the ICX switch and provided by DHCP Option 43, the configured list on the switch takes priority over DHCP Option 43. If none of the IP addresses in the configured list are reachable, the switch will try to reach the addresses received by DHCP Option 43.

The switch connects to SmartZone using a reverse SSH tunnel.

Examples

The following example shows the configuration of three passive SmartZone IP addresses.

ICX(config)# sz passive 192.168.11.200 192.168.11.201 192.168.11.202
