3. Configure the following parameter(s) as required:
Parameter Description
Port Synopsis: 1 to maximum port number
Default: 1
The port number as seen on the front plate silkscreen of the switch.
Ingress Limit Synopsis: 100 to 2000 or { Disabled }
Default: 2000
The rate after which received frames (of the type described by the ingress frames
parameter) will be discarded by the switch.
Ingress Frames Synopsis: { Broadcast }
Default: Broadcast
This parameter specifies the types of frames to be rate-limited on this port. It applies
only to received frames:
• Broadcast - only broadcast frames
Egress Limit Synopsis: { Broadcast, Multicast, Mcast&FloodUcast, All }">62 to 256000 Kbps or
{ Disabled }
Default: Disabled
The maximum rate at which the switch will transmit (multicast, broadcast and unicast)
frames on this port. The switch will discard frames in order to meet this rate if required.

Section 3.6.8
Configuring Port Mirroring
Port mirroring is a troubleshooting tool that copies, or mirrors, all traffic received or transmitted on a designated
port to specified mirror port. If a protocol analyzer is attached to the target port, the traffic stream of valid frames
on any source port is made available for analysis.
Select a target port that has a higher speed than the source port. Mirroring a 100 Mbps port onto a 10 Mbps port
may result in an improperly mirrored stream.
Frames will be dropped if the full-duplex rate of frames on the source port exceeds the transmission speed of the
target port. Since both transmitted and received frames on the source port are mirrored to the target port, frames
