The default PNNI level for Cisco MGX and SES switch products is 56, which is the midpoint of the recommended values. If this is the lowest level that you expect to need, you can accept the default. If you anticipate needing lower levels in the future, you should select the lowest level that you think you will need now, and enter the level number in the Nodal Address Worksheet, Table 3-4, which appears at the end of this chapter. If you are planning to create higher PNNI levels, you can also note these in the worksheet.

Note If your ATM network connects to a public network, or if you want to conform to public network ATM address rules for future expansion, you cannot create more than one peer group at PNNI levels 1 through

8.This is because the first 8 bits (byte 1) are reserved for the AFI and must be set to a fixed value. Also, if the address format you choose is DCC AESA or ICD AESA, you can create only one peer group for each DCC or ICD.
