NetPrefix

Use NetPrefix to manipulate network ATM address prefixes on a particular port. This 13-bytenet prefix is based on a hierarchical addressing scheme. The default value starts with the first byte being set to 39 (DCC address format), followed by nine pairs of 00s. The net prefix value is typically supplied by the network side of the UNI (user network interface). The net prefix, combined with the ESI (End System Identifier) and the SEL (selector) fields supplied by the user side of UNI, forms the ATM address. See the Structure of ATM address and NetPrefix diagram page2-121.

Administrator

Changes a net prefix for a particular port. Only one net prefix can be assigned per port. When a net prefix for a port is modified, all routes under the old net prefix are flushed and all SVC connections, QSAAL, and ILMI links are released. You must reboot for this command to take effect.
