Each ESI can have up to 255 associated selectors (0x00 through 0xff). The
range of selectors is partitioned into two subranges, a configured selector
range and an automatically assigned selector range. The ATM interface
parameter max-configured-selector gives the upper bound on the configured
selector range.
The ATM components on the router have various ways of choosing a
selector. Some components require you to explicitly configure a selector
from the configured selector range. Other components, such as Classical IP
clients, allow the selector to be automatically assigned at run-time. You do
not have to choose the selector because the router does this when it
activates. This selector is not guaranteed to be consistent across router
restarts. Automatic selector assignment is useful only for those ATM
components whose ATM address does not have to be already known by
other network devices.
The relative sizes of the selector range can be modified to conform to the
types and numbers of ATM users on the router.
Valid Values:
0 – 255 (0x00 – 0xFF)
Default Value:
200
Note: The selector is byte 20 of a 20-byte ATM address.
Example:
ATM INTERFACE> set max-config-selectors 225
max-frame
Sets the maximum number of octets permitted in any data frame sent or
received on the ATM interface. System memory is allocated based upon this
parameter. Increasing the max-frame requires more system memory, but
allows processing of larger frames.
All router entities using the ATM interface must use a maximum frame size
less than or equal to the max-frame-size of the ATM interface. This includes
all LECs and 1483 bridge interfaces.
Valid Values:
An integer in the range 16 – 32000
Default Value:
9234
Example:
ATM INTERFACE> set max-frame 1000
max-mp-parties
Sets the maximum number of leaves on a point-to-multipoint connection
initiated by the router. This parameter affects system memory allocation.
Increasing this value is necessary if the router must set up
point-to-multipoint connection(s) to a large number of destinations.
Valid Values:
An integer in the range 1 – 5000
Default Value:
512
