AT-S7/AT-S9 Operations Manual Permanent Virtual If connections are established manually through either network management or remote communications, the channels are called Permanent Virtual Circuits Circuits (PVCs). PVCs are implemented through either a management program termed Omega or a remote management station. With this release, each switch must have a PVC connection between itself and every other switch.
Product Description Ethernet Switching There are two popular methods to forward information: store-and-forward and cut-through. Although your switch employs store-and-forward as the default, you can also choose cut-through. Store-and-forward Store-and-forward means that your switch stores the entire packet and then forwards it.
Page 19
AT-S7/AT-S9 Operations Manual If a packet’s MAC address is not already stored in the Bridge Address Table, the switch adds the learned address, the associated port number and a timer value that indicates the age of the dynamic Bridge Address Table entry. Consequently, the switch knows the address and associated port number the next time it sees that address.
Chapter 2 Getting Started A completely functional ATM network requires the successful integration of several disparate units: An AT-4016TR or AT-4016F Ethernet-to-ATM switch, or An AT-TS95TR Ethernet-to-ATM switch ATI’s Omega management software An optional ATM-to-ATM Switch Getting started involves the following sequence: 1.

Appendix A TFTP Background Software can be downloaded using the Trivial File Transfer Protocol (TFTP) and ATI’s image file. ATI’s switches support the use of TFTP in ASCII mode to both upload configuration parameters to a host and/or download configuration parameters to a switch. What this means is straightforward: you can save configuration data from many switches to a single host.
TFTP TFTP To CIB Configuration Data Requirements The following information lists the configuration field and the required character string that precedes the user configuration value that has been chosen. Each configuration field data text string entry must be separated from the previous and the following by new line character sequence, i.e., carriage return (0x0D hex) or carriage return/linefeed (0x0D 0x0A hex) character combination.
Not all configuration fields apply to all products. This file includes configuration data for AT-S7 (4016 with PVC’s), AT-S6 (3690), AT-S9 (TS95) with PVC’s and AT-S13(4016 with SVC’s). Exceptions are noted. To obtain a current image for an AT-4016TR/AT-4016F or AT-TS95TR respectively, enter either: tftp get image.s7 123.0.0.5 ATS7 octet tftp get image.s9 123.0.0.5 ATS9 octet...
TFTP When you use TFTP, the file name for the switch must be the same as the downloaded password.
