Known Restrictions and Limitations Layer 2 802.1AB (LLDP) Description LLDP-MED location and inventory transmit TLVs have no effect. User Impact The switch does not support configuring this data so enabling these TLVs has no effect. QoS Description Traffic permitted by an outbound ACL on one port can be allowed on another port. Ip-dscp-mapping is not working as per the configured priority Queues on 10G (CX4) ports. User Impact This behavior is a limitation of implementing egress ACLs on an ingress classifier. Given a configuration where two outbound ACLs are active on different ports. Since both ACLs are applied in the 'out' direction, the rules programmed into the IFP will match on any ingress port. Ultimately, w/ the implementation of egress ACLs on the ingress classifier, unexpected behavior occurs if overlapping rules (i.e. a given packet can match multiple rules) are applied to different ports in the outbound direction. This is only an issue when forwarding traffic between 10G interfaces on different switches in a stack. The stack link can only support 12G so if it is oversubscribed, the effects of the queues are reduced. 802.1X Description Windows Vista® Authentication User Impact The Windows Vista® client could fail to authenticate properly when the option to cache user credentials is selected. Workaround: 1. In Control Panel Æ Network Connections, right-click on the desired Local Area Connection and select Properties. 2. In the Properties window, select the Authentication tab. 3. Deselect the checkbox for Cache user information for subsequent connections to this network. 4. Click OK. 28 System Firmware Version 3.2.0.6

Known Restrictions and Limitations
Layer 2
802.1AB (LLDP)
Description
User Impact
LLDP-MED location and inventory
transmit TLVs have no effect.
The switch does not support configuring this data so enabling these TLVs
has no effect.
QoS
Description
User Impact
Traffic permitted by an outbound
ACL on one port can be allowed on
another port.
This behavior is a limitation of implementing egress ACLs on an ingress
classifier.
Given a configuration where two outbound ACLs are active on different
ports. Since both ACLs are applied in the 'out' direction, the rules
programmed into the IFP will match on any ingress port. Ultimately, w/ the
implementation of egress ACLs on the ingress classifier, unexpected
behavior occurs if overlapping rules (i.e. a given packet can match multiple
rules) are applied to different ports in the outbound direction.
Ip-dscp-mapping is not working as
per the configured priority Queues on
10G (CX4) ports.
This is only an issue when forwarding traffic between 10G interfaces on
different switches in a stack. The stack link can only support 12G so if it is
oversubscribed, the effects of the queues are reduced.
