Sets fabric-related MP Router configuration parameters.
Synopsis
configure
Availability
admin
Description
Use this command to interactively set the following fabric-related MP Router configuration parameters:
configure
Domain The domain number uniquely identifies the MP Router in a fabric.
This value is automatically assigned by the fabric if it is not
configured by the user.
BB Credit The buffer-to-buffer (BB) credit represents the number of
frame-receipt buffers available to attached devices. The range of
allowed values varies, depending on other system settings.
R_A_TOV The resource allocation timeout value (R_A_TOV) is displayed in
milliseconds. This variable works with the variable E_D_TOV to
determine the actions of the MP Router when the next error
condition occurs.
Allocated circuit resources with detected errors are not released
until the time value has expired. If the condition is resolved prior
to the timeout, the internal timeout clock resets and waits for the
next error condition.
E_D_TOV Error detect timeout value (E_D_TOV) is displayed in
milliseconds. This timer flags a potential error condition when an
expected response is not received (an acknowledgement or reply
in response to packet receipt, for example) within the set time
limit.
Data Field Size This specifies the largest possible value, in bytes, for the data
frame size. The MP Router advertises this value to other MP
Routers in the fabric during construction of the fabric as well as to
other devices when they connect to the fabric. Setting this to a
value smaller than 2112 can result in decreased performance.
Port ID Format This specifies the port ID format:
1 Core switch ID format
2 Extended edge port ID format
WAN_TOV Wide area network timeout value (WAN_TOV) is displayed in
milliseconds. This timer is the maximum frame timeout value for a
WAN, if any, interconnecting the Fibre Channel islands. The
valid values range from 1000 to R_A_TOV/4.
MAX_HOP_COUNT Maximum hop count (MAX_HOP_COUNT) is an integer
denoting the maximum hops a frame might have to take to reach
any destination port from any source port across the fabric.
