Port Mirroring Title Gigabit ports mirroring in stacking mode Tagged traffic in port mirroring Mirroring of PAUSE frames Broadcast Storm Control Title Storm control on G2 port Link Aggregation (LAG) Title Joining a port to a LAG Port in LAG MAC addresses learning Description In cases where both source and destination ports are Gigabit ports, some of the packets may be dropped due to the stacking management traffic. All traffic on the mirroring target port is always tagged (even if originally it was sent untagged). Destination port does not receive PAUSE frames. Description Since the G2 stacking port is used for internal management traffic, storm control is disabled on the G2 stacking port. Description Joining a port to a LAG is possible only if: • There is no Layer 3 interface defined on the port. • The port does not belong to any VLAN. • The port does not belong to any other LAG. • The port is not a mirrored port. • The port 802.1p priority is equal to LAGs 802.1p priority. • An ACL is not defined on the port. • QoS Trust is disabled on the port. • GVRP is not enabled on the port. When a port is a member of LACP LAG under traffic, MAC addresses are learned on the port until it actually joins to the LAG. Rapid Spanning Tree (RSTP) Title RSTP port roles indications Description The command show spanning-tree interface does not show RSTP port roles, nor does the Web-based management. Layer3 IP Title Ping to self QoS/ACLQoS Title Changing priority-queue command cancels wrr-bandwidth settings Editing ACL from CLI Description PowerConnect 3348/3348 cannot ping itself.

All traffic on the mirroring target port is always tagged (even if originally it was sent
untagged).
Mirroring of PAUSE frames
Destination port does not receive PAUSE frames.
Broadcast Storm Control
Title
Description
Storm control on G2 port
Since the G2 stacking port is used for internal management traffic, storm control is
disabled on the G2 stacking port.
Link Aggregation (LAG)
Title
Description
Joining a port to a LAG
Joining a port to a LAG is possible only if:
There is no Layer 3 interface defined on the port.
The port does not belong to any VLAN.
The port does not belong to any other LAG.
The port is not a mirrored port.
The port 802.1p priority is equal to LAGs 802.1p priority.
An ACL is not defined on the port.
QoS Trust is disabled on the port.
GVRP is not enabled on the port.
Port in LAG MAC addresses learning
When a port is a member of LACP LAG under traffic, MAC addresses are learned
on the port until it actually joins to the LAG.
Rapid Spanning Tree (RSTP)
Title
Description
RSTP port roles indications
The command
show spanning-tree interface
does not show RSTP port roles, nor does
the Web-based management.
Layer3
IP
Title
Description
Ping to self
PowerConnect 3348/3348 cannot ping itself.
QoS/ACLQoS
Title
Description
Changing priority-queue command
cancels
wrr-bandwidth
settings
Changing the
priority-queue out num-of-queues
command value leaves any existing
wrr-bandwidth
commands.
Editing ACL from CLI
Once an ACL is bound to an interface it cannot be edited from the CLI
