Switch Manager Administrative State parameter The switch administrative state determines the operational state of the switch. The switch administrative state exists in two forms: the configured administrative state and the current administrative state. ■ The configured administrative state is the state that is saved in the switch configuration and is preserved across switch resets. Switch Manager always makes changes to the configured administrative state. The configured administrative state is displayed in the Switch Properties dialog box. ■ The current administrative state is the state that is applied to the switch for temporary purposes and is not retained across switch resets. The current administrative state is set using the Set Switch command. See the "Set command" on page 135. Table 13 describes the administrative state values. Table 13: Switch administrative states Parameter Online Offline Diagnostics Description The switch is available. The switch is unavailable. The switch is in diagnostics mode, is unavailable, and tests can then be run on all ports of the switch. Domain ID and Domain ID Lock parameters 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, reassigns any domain ID conflicts and establishes the fabric. If you lock the domain ID on a switch and a domain ID conflict occurs, one of the switches isolates as a separate fabric and the Logged-In LEDs on both switches flash to show the affected ports. See the "Set Config command" on page 137 for information about the switch keyword and the Domain ID Lock and Principal Priority parameters. If you connect a new switch to an existing fabric with its domain ID unlocked, and a domain conflict occurs, the new switch isolates as a separate fabric. However, you can remedy this by resetting the new switch or taking it offline then back online. The principal switch reassigns the domain ID and the switch joins 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 parameter Broadcast is supported, which allows for TCP/IP support. Broadcast is implemented using the proposed standard specified in Multi-Switch Broadcast for FC-SW-3, T11 Presentation Number T11/02-031v0. Fabric Shortest Path First (FSPF) is used to set up a fabric spanning tree used in transmission of broadcast frames. Broadcast frames are retransmitted on all online F_Ports. Broadcast zoning is supported with Access Control List (ACL) hard zones. When a broadcast frame is received, these hard zones are enforced at the F_Port.

Administrative State parameter
The switch administrative state determines the operational state of the switch. The switch
administrative state exists in two forms: the configured administrative state and the current
administrative state.
■
The configured administrative state is the state that is saved in the switch configuration
and is preserved across switch resets. Switch Manager always makes changes to the
configured administrative state. The configured administrative state is displayed in the
Switch Properties dialog box.
■
The current administrative state is the state that is applied to the switch for temporary
purposes and is not retained across switch resets. The current administrative state is set
using the Set Switch command. See the “
Set command
” on page 135.
Table 13
describes the administrative state values.
Domain ID and Domain ID Lock parameters
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, reassigns any domain ID conflicts and establishes the fabric. If you lock the domain ID
on a switch and a domain ID conflict occurs, one of the switches isolates as a separate fabric
and the Logged-In LEDs on both switches flash to show the affected ports. See the “
Set
Config command
” on page 137 for information about the switch keyword and the Domain ID
Lock and Principal Priority parameters.
If you connect a new switch to an existing fabric with its domain ID unlocked, and a domain
conflict occurs, the new switch isolates as a separate fabric. However, you can remedy this by
resetting the new switch or taking it offline then back online. The principal switch reassigns
the domain ID and the switch joins 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 parameter
Broadcast is supported, which allows for TCP/IP support. Broadcast is implemented using the
proposed standard specified in
Multi-Switch Broadcast for FC-SW-3, T11 Presentation

. Fabric Shortest Path First (FSPF) is used to set up a fabric spanning
tree used in transmission of broadcast frames. Broadcast frames are retransmitted on all online
F_Ports. Broadcast zoning is supported with Access Control List (ACL) hard zones. When a
broadcast frame is received, these hard zones are enforced at the F_Port. If the originator of
