AT-S62 Version 1.4.0 Software Release Notes
PN: 613-000490 Rev. A 4 Allied Telesyn, Inc.
event the management software on a switch is rolled back to an earlier version of the AT-S62
software. In such an event, only the first 14 characters of an extended SNMP community
string are displayed.)
Resolved Issues
 AT-8550GB and AT-8550SP switches and BPDUs. The AT-8550GB and AT-8550SP
switches did not transmit BPDUs when STP, RSTP, or MSTP was activated. This problem is
resolved.
 SNMP community strings and special characters. The management software now displays
an error message if you include a special character in an SNMP community string. The only
permitted characters are alphanumeric characters (A to Z, a to z, and 0 to 9).
 SNMP AtiStkSwMacAddr2VlanEntry MIB object. This object displayed only the MAC
addresses learned by the ports that were members of the management VLAN. The object
now displays all learned MAC addresses. (3144)
 System Date and Time. The individual fields for manually entering the system’s time and date
in the web browser interface were not labelled. This problem is resolved. (3002)
 Denial of Service Defense. Specifying a mirror port for the IP options defense mechanism
periodically caused the switch to enter a fault state where it rejected commands to enable or
disable the defense mechanism. This problem is resolved. The manner in which the destina-
tion port of the mirrored traffic is specified has been changed. To mirror the traffic of a
defense mechanism that supports traffic mirroring, you now must activate the port mirroring
feature and specify the destination port from that feature, rather than from within a denial of
service defense mechanism. (3004)
 System temperature threshold. A change to the temperature threshold was not retained after
a system reset or power cycle. The command for setting the threshold has been removed.
This parameter can no longer be adjusted from its default setting of 60
° Celsius. The switch
sends an SNMP trap if the threshold is exceeded. (2941)
 AT-A47 module. The management software stopped responding to commands when
instructed to display the operating settings of an AT-A47 module. This issue is resolved.
(3316)
 SNMP. The management software slowed or stopped responding after some SNMP func-
tions, such as snmpwalk. This issue is resolved. (3646)
 Telnet management session. Repeatedly logging in from a Telnet management session and
displaying system files caused the management software to stop saving configuration
changes to the active boot configuration file. It also stopped displaying the system files. This
issue is resolved. (3683)
 ARP request. The switch stopped forwarding packets and responding to management com-
mands if it received an ARP request with a source MAC address identical to its own address.
This issue is resolved. (3721)
 IP address. The switch stopped forwarding packets and responding to management com-
mands if it detected a node whose IP address was the same as its own address. This issue is
resolved. (3764)
 Port status. The management software stopped responding to commands if a port was con-
tinuously polled for its status over an extended period of time. This issue is resolved. (3802)
