Chapter 3 Address and Closed User Group Planning

Planning Address Configuration Settings

•If you change the address format, you need to change the peer group ID.

•If you change any of the identifiers within the unique portion of the peer group ID (for example, the ICD), you must change the peer group ID.

Enter the peer group ID into the Nodal Address Worksheet, Table 3-4, which appears at the end of this chapter.

Selecting the ATM Address

The node ATM address must be unique on the WAN and conform to the selections you have made for the following parameters:

•Address format

•Peer group ID

The first byte (47) of the default address identifies the address as an International Code Designator (ICD) ATM End Station Address (AESA). The second and third bytes (0091) define the globally unique ICD assigned to Cisco, and the next four bytes (81000000) are identical for all Cisco MGX and SES switch products. The unique portion of the default node address is the 6-byte MAC address, which is used in bytes 8 through 13 and again in bytes 14 through 19. Byte 20, which is the selector byte, is set to 00 by default.

Note Cisco recommends that you change the Cisco ICD portion of the address (0091). This number is registered to Cisco and using it will cause conflicts if the network you create is ever connected to a network to which Cisco connects, or to a network that is using Cisco equipment with the default parameters.

You do not have to change the default ATM address for Cisco MGX and SES switch products if the combination of the peer group ID and the MAC address is acceptable. If you want to create a custom ATM address for the switch, enter the address into the Nodal Address Worksheet, Table 3-4, which appears at the end of this chapter.

Caution The default ATM address is created using the primary PXM45 or PXM1E card MAC address. If the default address is being used and the primary PXM card is replaced, the ATM address of the switch changes. After replacing a PXM card, check the switch ATM address and reconfigure it if necessary. To avoid this problem entirely, configure a unique ATM address for the switch.
