KSWD
(continued)
• VS daemon (vsd)
• Web linker daemon (weblinkerd)
• Web Tools daemon (webd)
• ZONE daemon (zoned)
KTRC Kernel RAS trace module.
L2SYS L2SYS error messages indicate problems with the Layer 2 System manager that controls the Layer 2
forwarding engine and controls the learning/aging/forwarding functionality.
LACP LACP error messages indicate problems with the Link Aggregation Control Protocol module of the
Fabric OS.
LANCE LANCE error messages indicate problems with the LANCE module of the Fabric OS.
LFM LFM error messages indicate problems with the logical fabric manager module that is responsible
for making a logical switch use XISLs. This involves creating and managing LISLs in a logical fabric.
LOG RASLog subsystem.
LSDB The link state database is a part of the FSPF protocol that maintains records on the status of port
links. This database is used to route frames.
MCAST_SS The Multicast Sub-System messages indicate any problems associated with the Layer 2 and Layer 3
Multicast platform support, including allocation of global platform resources such as MGIDs,
hardware acceleration resources for Multicast, and route programming into the hardware (Layer 2
EXM for IGMP Snooping).
MFIC MS-FICON messages relate to Fibre Connection (FICON) installations. Fibre Connection control unit
port (FICON-CUP) messages are displayed under the FICU module.
MPTH Multicast path uses the shortest path first (SPF) algorithm to dynamically compute a broadcast tree.
MQ Message queues are used for interprocess communication. Message queues allow many messages,
each of variable length, to be queued. Any process or interrupt service routine (ISR) can write
messages to a message queue. Any process can read messages from a message queue.
MS The Management Service enables the user to obtain information about the Fibre Channel fabric
topology and attributes by providing a single management access point. MS provides for both
monitoring and control of the following areas:
• Fabric Configuration Server: Provides for the configuration management of the fabric.
• Unzoned Name Server: Provides access to Name Server information that is not subject to zone
constraints.
• Fabric Zone Server: Provides access to and control of zone information.
MSTP MSTP error messages indicate problems with Multiple Spanning Tree Protocol modules of the Fabric
OS.
NBFS NBFSM is a part of the fabric shortest path first (FSPF) protocol that handles a neighboring or
adjacent switch’s finite state machine (FSM).
Input to the FSM changes the local switch from one state to another, based on specific events. For
example, when two switches are connected to each other using an interswitch link (ISL) cable, they
are in the Init state. After both switches receive HELLO messages, they move to the Database
Exchange state, and so on.
NBFSM states are Down (0), Init (1), Database Exchange (2), Database Acknowledge Wait (3),
Database Wait (4), and Full (5).
NS Indicates problems with the simple Name Server module.
NSM NSM error messages indicate problems with the Interface Management and VLAN Management
module of the Fabric OS.
