Description: This attribute specifies the maximum subnet packet size used for the connections originating or terminating on this module. All modules in the same network should have the same maxSubnetPacketSize.

If this value is not identical throughout the network, the following points need to be considered:

a) When Passport and DPN switches are connected in the same network, the maxSubnetPacketSize on a DPN switch can be at most 2048 and the DPN part of the network must be configured with hardware which supports this size:

- Dedicated PE386 Network link/Trunk - Minimum measured link speed of 256Kbits/sec

This hardware has to be present on every potential data path between connecting end points!

b) The calling end of the connection signals the maxSubnetPacketSize value to the called end. The called end then compares this value to its own provisioned value and selects the smaller value. Note that this smaller value is not signalled back to the calling end. The calling and called ends can therefore have different maxSubnetPacketSize values.
