AT-S63 Version 4.1.0 Patch 2 Software Release Notes

PN 613-001278 Rev A 9 Allied Telesis, Inc.

Version 4.1.0 Operational Notes

 Stacking and IGMP snooping. IGMP snooping on a stack requires that a multicaster be on

the master switch.

 Web server. The default setting for the web server on the switch has been changed from

enabled to disabled. To manage the switch with a web browser, enable the server with the

ENABLE HTTP SERVER command.

 Classifier criteria. Access control lists and Quality of Service policies cannot filter on the

following combinations of classifier criteria:

— VLAN ID and source or destination IP address.

— Protocol and source or destination IP address

This rule applies whether the criteria are in the same classifier or in different classifiers that

are applied to the same access control list or Quality of Service policy.

 Protocol (Layer 2) IP criterion - Do not use the IP value in the Protocol (Layer 2) variable of a

classifier to filter IP traffic. The results may be unpredictable. Instead, use the IP source or

the IP destination criterion. The following values can be used to filter large IP address ranges:

 ID numbers of ACLs. The ID numbers of permit ACLs have to be less than the ID numbers of

deny ACLs. Otherwise, the results might be unpredictable on ports that have both permit and

deny ACLs. To avoid this issue, start numbering your permit ACLs at ID number 1 and your

deny ACLs at ID number 100.

 ID numbers of QoS policies. If you assign two QoS policies to the same port and one of the

policies is filtering on a subset of the IP addresses of the other policy, the ID number of the

subset policy has to be lower than the ID number of the other policy. Otherwise, the results

might be unpredictable.

 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
