- Group 2: Ports 25 to 48 and 50
 Quality of Service. The bandwidth meters on an AT-8500 Series switch are applied to port
blocks with each block consisting of eight ports (e.g., 1 to 8, 9 to 16, etc.) Bandwidth alloca-
tion for the packet flow of a defined traffic class is equally divided among the ports of a block.

 Configuration files. A boot configuration file with a large number of commands can take up to
two minutes for the switch to load. (1093)
 Configuration files. Do not use Microsoft’s NotePad to edit or view a configuration file. Some
versions of NotePad may add formatting codes to the file. Use WordPad instead, or some
other text editor that will not add formatting codes to the file. When saving the file, do not
change the “.cfg” extension in the filename and be sure to save the file without formatting
codes.
 Configuration files. The AT-S62 Management Software Menus Interface User’s Guide incor-
rectly states that the name of the default boot configuration file is default.cfg. The correct
name is boot.cfg.
 Enhanced stacking. The enhanced stacking feature of the AT-S62 management software
uses the IP address 172.16.16.16. Do not assign this address to any device on a subnet
when using the enhanced stacking feature.
 Enhanced stacking. An AT-8500 Series switch functioning as the master switch of an
enhanced stack must be running AT-S62 V1.2.1 or later to recognize an AT-8524POE switch
in a stack. The management software on a master AT-8500 Series switch running an earlier
version should be upgraded if a stack contains an AT-8524POE switch.
 Login password. The maximum length of a login password is 16 alphanumeric characters for
manager accounts created through the RADIUS and TACACS+ authentication protocols and
passwords for supplicant accounts for 802.1x port-based access control. Manager and sup-
plicant accounts with passwords exceeding the limit are denied access to the switch.
 Port settings. The parameter settings of a port are not returned to the default values when a
port is removed from a port trunk. The port retains the settings it had as a member of the
trunk. (2144)
 Port settings. The PORT parameter featured in many of the AT-S62 command line com-
mands has an ALL option for specifying all ports on a switch. However, for AT-8516F/SC and
AT-8524M switches, the option only works when both expansion slots contain expansion
modules. Otherwise, the switch displays an error message. To specify all ports on a switch
where one or both expansion slots are empty, enter the ports as a range. For example, for an
AT-8524M switch you would enter PORT=1-24. (2026)
 Port settings. Flow control and back pressure on the AT-8550GB and AT-8550SP switches
are operational among devices connected to the following port groups, but are not opera-
tional between these two groups: (1361)
- Group 1: Ports 1 to 24 and 49
- Group 2: Ports 25 to 48 and 50
 TFTP. The management software can take up to four minutes to time out a failed TFTP down-
load, during which time you will be unable to manage the switch. (1171)
 SNMP MIBs. The following MIB objects are not supported: AtiStkSwPortMirroringConfigInfo -
SourceModuleId, AtiStkSwPortMirroringConfigInfo - SourcePortId, and AtiStkSwPortMirror-
ingConfigInfo - DestinationModuleId. (1829)
