6.15 PORT REDIRECT CONFIGURATION SCREEN
The Port Redirect Configuration screen, Figure 6-17 , enables the user to
redirect frames from a source port to a destination port. Frames received
on the source port can be redirected and transmitted in the frame format in
which they are received (normal) or they can be redirected with a VLAN
Tag (TAGGED) or without a VLAN Tag (UNTAGGED). Also, any
errored frames received can be either dropped or forwarded to the
destination port. For example, port 1 can be set as the source port with
port 2 as the destination port. Frames from port 1 are then automatically
redirected to port 2 according to the configured frame format, and frames
with errors can be either forwarded or dropped according to the screen
settings.
The port redirect function is very useful for troubleshooting purposes, as
it allows traffic to be sent to a particular port where, with the use of an
analyzer or RMON probe, all current traffic from the source port can be
examined.
To access the Port Redirect Configuration screen from the Redirect
Configuration Menu screen, use the arrow keys to highlight the PORT
REDIRECT CONFIGURATION menu item and press ENTER. The
Port Redirect Configuration screen displays.
If the module is set to STAND ALONE mode (set in the General
Configuration screen), the chassis version of the Port Redirect
Configuration screen, described in
Section 5.13 displays. This
allows for remapping to other modules in the chassis (remote
remapping). Note that it is up to the user to select the correct
numbers of the available modules and ports for redirect
purposes.
If an optional ATM interface is installed, up to 128 ports may be
set, which includes ATM Permanent Virtual Circuits (PVCs).
Although all traffic from the source port (including, if desired,
errored frames) is sent to the destination port, normal switching
is still performed for all frames on the source port.
