What is domain ID in FC?
The domain manager on the principal switch in a VSAN assigns a domain ID to a switch that is joining the fabric. When a switch boots up or joins a new fabric it can request a specific domain ID or take any available domain ID.
What is domain ID in switch?
Switch Domain IDs The Domain ID is actually a unique ID for each individual switch in that fibre channel network. The Domain ID is a value from 1 to 239 on both Cisco and Brocade switches. One switch in the network will be automatically assigned as the Principle Switch.
What is Observation domain ID?
Observation Domain ID: (IPFIX) An identifier of an Observation Domain that is locally unique to an Exporting Process. The Exporting Process uses the Observation Domain ID to uniquely identify to the Collecting Process the Observation Domain where Flows were metered.
How do I change my domain ID on a switch?
Enter a unique domain ID at the Domain prompt….Use the following procedure to set the domain ID:
- Connect to the switch and log in on an account assigned to the admin role.
- Enter the switchDisable command to disable the switch.
- Enter the configure command.
- Enter y after the Fabric parameters prompt.
What does an area ID represent in Fibre Channel FC addressing?
A domain ID is a unique number that identifies the switch or director to a fabric. One byte allows up to 256 possible addresses.
What is E_port?
An Expansion port (E_port) is an inter-switch port used in fiber channel topology to connect two fiber switches. An E_port is connected to another E_port to create an inter-switch link (ISL).
How do I find my domain ID on my Brocade switch?
Enter fabricshow to determine the domain IDs that are currently in use. To modify the domain ID: Enter switchdisable to disable the switch. Enter configure, and then enter a new value or press Enter to accept each default value.
What is WWPN & Wwnn?
A WWPN is a World Wide Port Name; a unique identifier for each Fibre Channel port presented to a Storage Area Network (SAN). Each port on a Storage Device has a unique and persistent WWPN. A World Wide Node Name, WWNN, or WWnN, is a World Wide Name assigned to a node (an endpoint, a device) in a Fibre Channel fabric.
What is WWN storage?
A World Wide Name (WWN) is a unique identifier that is assigned to a manufacturer by the Institute of Electrical and Electronic Engineers (IEEE) and hard-coded into a Fibre Channel (FC) device. WWNs are important when setting up a storage area network (SAN).
What does a WWN look like?
The WWN formats include: “Original” IEEE formats are essentially a two-byte header followed by an embedded EUI-48 address (which contains the OUI). The first 2 bytes are either hex 10:00 or 2x:xx (where the x’s are vendor-specified) followed by the 3-byte OUI and 3 bytes for a vendor-specified serial number.
What is E port in Brocade?
On each switch fabric, you must configure the switch ports that connect the Inter-Switch Link (ISL). These ISL ports are otherwise known as the E-ports.
