Switch Module Services

The domain ID lock allows (False) or prevents (True) the reassignment of the domain ID on that switch. Switches come from the factory with the domain ID set to 1, the domain ID lock set to False, and the principal priority set to

254.Refer to the McDATA Switch Module Management Guide for information about changing the domain ID and domain ID lock using McDATA Embedded Web Server. Refer to the Set Config command in the McDATA 4416 Command Line Interface Guide for information about changing the default domain ID, domain ID lock, and principal priority parameters.

An unresolved domain ID conflict means that the switch with the higher WWN will isolate as a separate fabric, and the Logged-In LEDs on both switches will flash green to show the affected ports. If you connect a new switch to an existing fabric with its domain ID unlocked, and a domain ID 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/port number pair or Fibre Channel address. You must reconfigure zones that are affected by domain ID reassignment. To prevent zoning definitions from becoming invalid under these conditions, lock the domain IDs using McDATA Embedded Web Server, McDATA Element Manager, or the Set Config Switch command.

You can configure your switch module to suit the demands of your environment by enabling or disabling a variety of switch services. Familiarize yourself with the following switch services and determine which ones you need:

•Telnet: Provides for the management of the switch over a Telnet connection. Disabling this service is not recommended. The default is enabled.

•Secure Shell (SSH): Provides for secure remote connections to the switch using SSH. Your workstation must also use an SSH client. The default is disabled.

•Switch Management: Provides for out-of-band management of SNMP and CIM. If this service is disabled, the switch can only be managed inband or through the serial port. The default is enabled.

•Inband Management: Provides for the management of the switch over an inter-switch link using McDATA Embedded Web Server, McDATA Element Manager, SNMP, or management server. If you disable inband management, you can no longer communicate with that switch by means other than a direct Ethernet or serial connection.The default is enabled.
