Jumbo Frames

Use the Jumbo Frames page to enable the switch to forward jumbo Ethernet frames. The jumbo
frames feature extends the standard Ethernet Maximum Transmission Unit (MTU) from 1518 bytes
(1522 bytes with a VLAN header) to 9216 bytes. If it is enabled, any device connecting to the
same broadcast domain should also support jumbo frames.
This feature is disabled by default.
To display the Jumbo Frames page, click Switching > Jumbo Frames in the navigation pane.

Port Mirroring

Port mirroring sends a copy of all packets sent and/or received on one port (the source port) to
another port (the destination port) for monitoring and analysis by an external network analyzer.
Multiple switch ports can be configured as source ports, with each port mirrored to the same
destination. You can also mirror the internal CPU traffic to an external port for debugging the CPU.
No destination port is defined by default. In its default state, the destination port does not participate
in traffic forwarding, and it cannot be configured to participate in VLANs.
CAUTION:
When configuring port mirroring, avoid oversubscribing the destination port to prevent the
loss of mirrored data.
While a port is used as the destination port for mirrored data, the port cannot be used for
any other purpose; the port will not receive and forward traffic.
To display the Port Mirroring page, click Switching > Port Mirroring in the navigation pane.
In the example configuration in
on Source Port 1 to Destination Port 4.
