Glossary
subnet mask
switch
A mask used by a computer to determine whether another computer
with which it needs to communicate is located on a local or remote
network. The network mask depends upon the class of networks to
which the computer is connecting. The mask indicates which digits to
look at in a longer network address and allows the router to avoid
handling the entire address. Subnet masking allows routers to move
the packets more quickly. Typically, a subnet may represent all the
machines at one geographic location, in one building, or on the same
local area network.
A device that connects, filters and forwards packets between local
area network (LAN) segments or storage area network (SAN) nodes
or devices.
switch binding
A feature that restricts the product from allowing connections with
the devices that are not listed on the Switch Binding Membership
List. Switch Binding is available only if the SANtegrity Binding
feature is installed.
switch binding
membership list
SBML. If switch binding is enabled, a list of devices with which the
product is allowed to make connections.
switched mode
If the arbitrated loop device is in switched mode, each pair of
communicating ports on the arbitrated loop device can share the
100 Mb bandwidth. In switched mode, up to three pairs of loop
devices can communicate with each other simultaneously. Or, a
public device on the loop can communicate with another device on
the fabric while up to two pairs of loop devices can communicate
simultaneously.
switchover
Changing a backup field-replaceable unit (FRU) to the active state,
and the active FRU to the backup state.
switch priority
Value configured into each switch in a fabric that determines its
relative likelihood of becoming the fabric’s principal switch. Lower
values indicate higher likelihood of becoming the principal switch. A
value of 1 indicates the highest priority; 225 is the lowest priority. A
value of 225 indicates that the switch is not capable of acting as the
principal switch. The value 0 is illegal.
