IBM SC30-3681-08 manual Max-frame, Max-mp-parties

ATM Interface Con®guration Commands (Talk 6)

Each ESI can have up to 255 associated selectors (0x00 through 0xff). The range of selectors is partitioned into two subranges, a con®gured selector range and an automatically assigned selector range. The ATM interface parameter max-con®gured-selector gives the upper bound on the con®gured selector range.

The ATM components on the router have various ways of choosing a selector. Some components require you to explicitly con®gure a selector from the con®gured 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 modi®ed 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
