AT-S63 Version 2.1.0 Software Release Notes
PN 613-000631 Rev A 10 Allied Telesis, Inc.

Switch to switch upload of a configuration file. The AT-S63 Management Software User
Guides state that the configuration file on a master switch retains its routing interface
commands when uploaded to a slave switch. This is incorrect when the file is the master
switch’s active configuration file. All routing interface commands are removed from the
master switch’s active configuration file when it is uploaded to a slave switch to prevent an IP
address conflict on the units. However, the routing interface definitions in the file are retained
when you upload any other configuration file from a master switch to a slave switch. (4272)
 Telnet management session. Changing the VLAN mode of a switch (e.g., from the user-
configured VLAN mode to a multiple VLAN mode) from a remote Telnet management session
may end your management session. To continue managing the switch, you must reestablish
the management session (3806)
 SNMPv3 management. The enhanced stacking feature is not supported from SNMPv3.
(4065)
 AtiStkSwVlanConfigEntry MIB table. The response time of the management firmware on the
switch will slow if you have more than one instance of the AtiStkSwVlanConfigEntry MIB table
open at a time. (2231)
 Compact flash card. The removal of a compact flash card from the switch while the
management software is writing a file to it may cause the switch to stop responding to
management commands and forwarding network packets. To avoid this issue, never remove
a compact flash card from the switch while the Fault LED on the front panel is on. Wait for the
Fault LED to turn off before removing the card.(4253)
 LACP priority value and the event log. A change to a switch’s LACP priority value is
registered in the event log with a message that reflects the current status of LACP, rather
than the change to the priority value. The log message is either “lacp:enabled” or
“lacp:disabled.” (3345)
 MAC address-based VLANs and static trunks. The documentation states that the ports of a
MAC address-based VLAN form a community and that the assignment of a MAC address to
one port in a VLAN is equivalent to assigning it to all ports. This is true except in the case
where the ports of a MAC address-based VLAN encompass a static port trunk, in which case
the same MAC addresses must be assigned to all the ports in the trunk. (3249)
 File upload or download. The switch’s response to management instructions may be slow
while it uploads or downloads a file to the file system.
 Flow control and back pressure. Flow control and back pressure are operational among
devices connected to ports 1 through 12 or ports 13 through 24 on the AT-9424T/GB and
AT-9424T/SP switches, but not between devices connected to ports 1 through 12 and 13
through 24. (1321, 1322)
 Reserved multicast traffic and port mirroring. The destination port of a port mirror may
transmit duplicates of some reserved multicast traffic, such as STP BPDUs and other control
packets. The duplication results from the destination mirror port transmitting both the
reserved multicast traffic it receives from flooded multicast traffic and the same multicast
traffic from the mirrored ports. (3055)
 Fiber optic port configuration display. The Auto-Negotiation, speed, and duplex mode settings
in the menus interface for ports 23 and 24 on the AT-9424T/GB and AT-9424T/SP switches
always reflect the settings of the corresponding twisted pair ports 23R and 24R. They do not
reflect the current settings of an active GBIC or SFP fiber optic port. (3047)
