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.

IPv4 Fragmentation support

The switch is not fragmenting the datagram and forwards even when the

IP MTU of the forwarding Interface is set to a lower value (than the

datagram size).

This is a hardware limitation and is working as designed. The HW does

not allow the IP MTU to be configured per VLAN. We can configure the

maximum frame size in HW using the 'mtu' command in interface Ethernet

mode. However, if a packet exceeds the maximum frame size for a port, it

is discarded. If a packet happens to be sent to the software and it exceeds

the IP MTU, then the packet still will not be fragmented. An ICMP error

message is sent to the sender.

ICMP Error message generation

The ICMP Error Message generated by the switch has the fields (TTL)

unmodified instead of sending with a modified value resulted as a part of

forwarding process.

ICMPv6 Packet Too Big

The system is not generating Packet Too Big message to the source when

it forwards the packet through an interface vlan with mtu smaller than the

packet being forwarded.

The PowerConnect 6200 Series switches do not have the capability to

enforce IP MTU on VLAN Routing interfaces.
