1. Fabric Login (FLOGI) creates link from N-port to switch by adding entry to Simple Name Server

(SNS) in the switch.

5. Each switch port automatically Logs_Out a link if it loses either light or carrier.

Port Login: PLOGI

ACC : Accept

Receives Parameters

ACKACK

HSG PLOGI to KGPSA

Entire n-port login sequence

2. Fabric notifies all N-Ports of new entry in the SNS (State Change Notification).

3. Each N-Port does a PLOGI to SNS to learn all N-Port WWIDs, then disconnects.

4. An N-port does a Process Login (PRLI) through fabric to another N-port to create connections.

Worldwide Name identification

All switches will have unique Worldwide Names as defined

by IEEE Every port and node is also assigned a unique Worldwide

Name

Node Worldwide Names follow IEEE standards and begin

with a 1, followed by the unique vendor id assigned byIEEE and ending with a vendor specified identifier

Port Worldwide Names also follow IEEE standards, andbegin with a 2

The next three nibbles relate to the physical port number

Next comes the IEEE assigned vendor id, followed by vendor

specified identifier
