AT-S63 Version 4.0.0 Patch 2 Software Release Notes

PN 613-001166 Rev A 11 Allied Telesis, Inc.



Port Mirroring. In order for a switch to mirror tagged packets, the VLANs of the packets must

exist on a switch. Packets that contain VIDs of nonexistent VLANs are not mirrored.

 Denial of Service defense mechanisms. The operation of a Denial or Service defense

mechanism on the switch might be unpredictable when a defense is assigned to more than

one port or when more than one defense is assigned to the same port. This issue can be

avoided by not assigning a defense mechanism to more than one port or more than one

defense mechanism to a port. This issue is limited to the AT-9424Ts and AT-9424Ts/XP

switches. (4196)

 QoS policies and unicast and multicast addresses. The filtering properties of a QoS policy

are designed for known unicast addresses. The behavior of a policy may be unpredictable if it

filters on unknown unicast addresses or known or unknown multicast addresses. (3196)

 Lowest numbered port in an LACP aggregator. You cannot delete the lowest numbered port

from an LACP aggregator, referred to as the base port, or add a port to an aggregator that is

below the base port. The OperKey parameter for the ports in an aggregator is based on the

lowest numbered port and cannot be changed after the aggregator is created. For example, if

you create an aggregator of ports 10 to 15 on a switch, you cannot later delete port 10 from

the aggregator or add a port less than port 10. You must recreate the aggregator if you need

to change the base port. (4369)

 Saving a configuration. The management software on the switch may experience a problem if

you save configuration changes in rapid succession. To avoid this issue, you should wait for

the Fault LED on the front panel of the switch to go off after saving a configuration change

and before saving another configuration change. If you are in a different location from the

switch and cannot view the Fault LED, wait 30 to 45 seconds between your save commands.

(2683)

 Multiple VLAN modes and IPv4 packet routing. The 802.1Q-compliant and non-802.1Q-

compliant multiple VLAN modes do not support IPv4 packet routing. If you activate one of

these modes, you cannot configure routing interfaces and all the existing routing interfaces,

with the exception of the local interface, are deleted. To assign an IP address to a switch

running one of these VLAN modes, you must create one routing interface and designate it as

the local interface while the switch is running in the user-configured VLAN mode, and

afterwards change the switch’s VLAN mode to 802.1Q-compliant or non-802.1Q-compliant.

The local interface is automatically moved to the VLAN on port 1. (3806)

 Switch to switch upload of a configuration file in an enhanced stack. The AT-S63

Management Software User Guides state that the routing interface commands in the

configuration file on a master switch of an enhanced stack are retained when the file is

uploaded to a slave switch. This is incorrect when the file being uploaded is the master

switch’s active configuration file. To prevent an IP address conflict on the units, the transfer

automatically removes all routing interface commands as the active configuration file is

uploaded. This rule only applies to the master switch’s active configuration file. The transfer

retains the routing interface definitions when you upload any other configuration file from a

master switch to a slave switch. To avoid an IP address conflict in this situation, it may be

necessary to modify the IP address assignments of the routing interfaces on the switch that

received the file.(4272, 5873)

 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)
