Each switch in the fabric must have a unique Domain ID. The Domain ID can be set using the configure command. You can also allow the Domain ID to be set automatically. The default Domain ID for the SAN768B IS 1.
To set the Domain ID, follow these steps:
1.Enter the fabric show command to determine the current Domain IDS available.
2.Enter the switch Disable command to disable the SAN768B
3.Enter the configure command. Enter y at the fabric parameters pro met: Fabric parameters (yes, y, no, n)
4.Then, enter a unique Domain ID
5.Complete the remaining prompts or press Ctrl+D to accept the other setting and to exit.
6.Enter the switch Enable command to re-enable the SAN768B.
7.Add SFPs and fiber optic cables to the ports as required. Cables: The ports and cables that are used in trunking groups must meet specific requirements.
8.Remove the shipping plug from the ports to be used.
9.Position the SFP so that the key (the tab near the cable-end of the SFP)is on top, and insert the SFP into the port until it is firmly seated and the latching mechanism makes a clicking sound. For specific instructions, see the SFP manufacture’s documentation. Attention: The SFP module is keyed so that it can only be inserted correctly into the port. If the module does not slide in easily, make sure it is not upside down.
10.Connect the fiber optic cable to the SFPs as appropriate to the fabric topology by positioning each cable so that the key (the ridge on one side of the cable connector) is aligned with the slot in the SFP, then inserting the cable into the SFP until it is firmly seated and the latching mechanism makes a clicking sound.
Attention: The cable is keyed so that it can only be inserted correctly into the SFP, if the cable does not slide in easily, try turning it over.
Attention: The cable is keyed so that it can only be inserted correctly into the SFP, if the cable does not slide in easily, try turning it over.
11.Verify the correct operation of the switch.
12.Enter the following command at the Telnet prompt to verify the switch and port status
Switch show Backups: This command provides information about the status of the switch and the ports. Always back up to the configuration after any initial configuration changes and then perform backups periodically thereafter. This ensure that a complete configuration is available if ever required for uploading to a replacement switch. Switch configuration is backed up by issuing a configupload to the FTP server. You must install a SFP module ineach interface connector on the controller where a fiber-optic cable is to be installed.
To give its customers flexibility as to the type of Ethernet links, even after the customer has bought the switch, Cisco switches include some physical ports whose port hardware can be changed later, after you purchase the switch. One type of port is called a gigabit interface converter(GBIC), which happened to first arrive on the market around the same time as Gigabit Ethernet, so it was given the same “gigabit”
name. More recently, improved smaller types of removable interfaces, called small form-factor pluggable (SFP), provide the same function of giving users the ability to swap hardware and change the type of physical link.

For example, Cisco SFP 10G SR, The Cisco SFP-10G-SR Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000MHz*km MMF (OM3), up to 300m link lengths are possible. Using 4700MHz*km MMF (OM4), up to 400m link lengths are possible. and its feature is that SFP+ transceiver module for MMF, 850-nm wavelength, LC duplex connector.
Cisco SFP-H10GB-CU1M, a kind of SFP-H10GB-CU1M, 1-m 10G SFP+ Twinax cable assembly and belongs to passive device. This is a 10-meter long twinax SFP cable providing 10 Gbps Ethernet. At a length of 10 meters, this cable requires active transceivers at both ends.
As you know, I work at Fiberstrore now, it designs, manufactures, and sells a broad portfolio of optical communication products, including passive optical network, or PON, subsystems, optical transceivers used in the enterprise, access, and metropolitan segments of the market, as well as other optical components, modules, and subsystems. And there is a good news that many products are in the price at a discount of 30% now and welcome to viit our online Fiberstore.
