1.3.6 ATM Adaptation Layer (AAL) Support
The 9A686-04 support all ATM Adaptation Layers, (AAL 1, AAL 3/4 and AAL 5).
1.3.7 Management LAN Emulation Client
The SmartSwitch 9500 system creates a default management LEC upon first initialization.
The LEC automatically joins the default ELAN. Although all modules in the chassis are
capable of becoming the LEC, only one LEC is active in the system at one time. This is
accomplished through a LEC election algorithm.
1.4 INTERFACE (PORT) NUMBERING
The 9A686-04 use a geographic interface numbering scheme that allows for easy identiÞca-
tion of each front panel and backplane interface of each 9A686-04 installed in the Smart-
Switch 9500 chassis. Interface numbers are generated as follows:
Slot ##, ANIM ##, Interface ##
Table 1-1 provides an example of how the interface numbering scheme works. In this
example, there is a SmartSwitch 9500 chassis with five 9A686-04 modules installed. These
modules are installed in slots 1, 3, 7, 11 and 14. Each of these modules are equipped with 4
ANIM 21/3s. This provides each 9A686-04 with 12 front panel interfaces. Refer to
Table 1-1
for a breakdown of the interface numbering scheme.
