# SANbox2-64 Switch Properties

Use the Switch Properties window to change the symbolic name, administrative state, domain ID, and to enable or disable broadcast support. Broadcast support provides support for IP broadcast over Fibre Channel.

Switch configuration is divided into two areas: chassis configuration and network configuration. Chassis configuration specifies parameters that relate to switch identity on the Fibre Channel network. To open the Switch Properties window, open the Switch menu and select Switch Properties.

Symbolic Name | A user defined name that identifies the switch. The default is SANbox2.
Administrative State | When applied to the switch, the administrative state becomes the operational state. Online - The switch is available. Offline - The switch is unavailable. Test - The switch is in test mode and is unavailable.
Domain ID | A unique Fibre Channel identifier for the switch. The Fibre Channel address consists of the domain ID, port ID, and the Arbitrated Loop Physical Address (ALPA). The domain ID must be unique for each switch in the fabric. The maximum number of switches within a fabric is 239 with each switch having a unique domain ID.
Domain ID Lock | The domain ID is a unique Fibre Channel identifier for the switch. The Fibre Channel address consists of the domain ID, port ID, and the Arbitrated Loop Physical Address (ALPA). The maximum number of switches within a fabric is 239 with each switch having a unique domain ID. Switches come from the factory with the domain IDs unlocked. This means that if there is a domain ID conflict in the fabric, the switch with the highest principal priority, or the principal switch, will reassign any domain ID conflicts and establish the fabric. If you lock the domain ID on a switch and a domain ID conflict occurs, one of the switches will isolate as a separate fabric and the Logged-In LEDs on both switches will flash to show the affected ports. If you connect a new switch to an existing fabric with its domain ID unlocked, and a domain conflict occurs, the new switch will isolate as a separate fabric. However, you can remedy this by resetting the new switch or taking it offline then back online. The principal switch will reassign the domain ID and the switch will join the fabric. Note: Domain ID reassignment is not reflected in zoning that is defined by domain ID and port number pair. You must reconfigure zones that are affected by domain ID reassignment.
Broadcast Support | Enables support for IP broadcast over Fibre Channel. Broadcast support is a simple form of broadcast zoning, which allows for TCP/IP support. Broadcast frames are revectored to the CPU and retransmitted out to all active (online) ports, except TL ports. The default setting is disabled.
Inband Management | The Inband Management option provides a method of enabling or disabling inband requests to the switch, such as SNMP, IPFC, Management Server, GUI, and API messaging across FC to our switch. The default setting is enabled. If disabled, no inband requests are routed to the switch.
FC-SW-2 Compliant | The FC-SW-2 Auto Save radio button enables or disables the availability of FC-SW-2 Auto Save mode. If the FC-SW-2 Auto Save parameter is disabled on the Switch Properties dialog, the FC-SW-2 Auto Save parameter is not available on the Edit Zoning Configuration dialog. Note: The FC-SW-2 Compliant setting must be the same on all switches in the fabric, otherwise the inter-switch links will not connect.
Legacy Address Format | The Legacy Address Format radio button is available (active) only when the FC-SW-2 Auto Save parameter is disabled, and should be enabled only to permit interoperation with certain older non-FC-SW-2 compliant switches. Enabling this feature under other circumstances will disable zoning that is defined by domain ID and port number. Note: The Legacy Address Format setting must be the same on all switches in the fabric, otherwise the inter-switch links will not connect. This setting is available only when the FC-SW-2 Compliant setting is disabled. Contact your authorized maintenance provider for assistance in using this feature.
Timeout Values | The switch timeout values determine the timeout values for all ports on the switch. The R_A_TOV or E_D_TOV values are the same for all switches in the fabric. These values can only be changed if the switch operational state is offline. After taking the switch offline, these fields become active. R_A_TOV Resource Allocation Timeout. The number of milliseconds the switch waits to allow two ports to allocate enough resources to establish a link. The default is 10000. E_D_TOV Error Detect Timeout. The number of milliseconds a port is to wait for errors to clear. The default is 2000.
