Configuring SVC Port Addresses
If the device attached to a given physical port does not support ILMI address
registration, or to fully specify an address to use for calling party screening, you can
define SVC addresses for all the logical ports on a given physical port. The AESA
formats must have full-length address definitions and include all 20 octets (40 hex
digits). That is, you must enter the AFI, IDI, HO-DSP, ESI, and SEL portions of the
address (since ATM routing does not use the SEL portion, you can enter any value for
that part of the address). For native E.164 addresses, enter the 1-15 digit E.164
address.
About Automatic Assignment of ESI Bytes
An SVC port address is created by appending a 13-byte node prefix with a six-byte
ESI portion, followed by a selector byte. This 20-byte address can then be used as an
SVC or SPVC endpoint.
The six-byte ESI portion can be automatically generated and assigned by
Navis EMS-CBGX. These six bytes are defined based on the shelf, slot, physical port,
and logical port IDs and can only be created automatically if node prefixes are already
configured on the switch. The automatic assignment of ESI bytes can be done for both
VNN and PNNI domains.
shows how the bits and bytes of the address are assigned.
Note – If the node prefix is configured to be less than 13 bytes, zeros will be
appended to the node prefix when the Auto ESI feature is used. Similarly, if the node
prefix is greater than 13 bytes, the bytes over 13 will be truncated by the Auto ESI
feature.
