Configuring the Cajun P550 Switch (Layer 2 & Layer 3)
3 -12 Cajun P550/P220 Switch Operation Guide
Using the All Ports Configuration Dialog Box
The All Ports Configuration dialog box allows you to apply the same parameter settings
to all switch ports for P220 switches and in a module for the P550 using a single
command.
To set all ports in a module:
1. In the System Configuration section of the Web Agent window, select Modules
& Ports. The Module Information dialog box opens.
2. In the Ports column, click the number for the module you want to configure (for
example, 10 for 100Base-FX). The Port Configuration dialog box opens.
3. Click All Module Switch Ports Configuration. The All Ports Configuration
dialog box opens.
4. Set port parameters as described beginning in “Configuring Physical Port
Parameters on Gigabit Ports” and/or “Configuring Physical Port Parameters on Fast
Ethernet Ports”, earlier in this chapter.
5. Click APPLY to save your changes, or CANCEL to restore previous settings.
Rate Limit Mode Prevents the switch from overwhelming the output buffer on
lower-speed ports by placing a threshold on the percentage of
port traffic that can be flooded packets (unknown unicasts and
multicasts). You can optionally include known multicast packets
in this percentage to further decrease the possibility of the port’s
output buffer being overwhelmed.
Rate Limit Rate Determines the percentage of a port’s forwarded traffic that can
be unknown unicast and multicast (flooded). Lower this value if
the port has overflow problems.
Rate Limit Burst Size Determines the limit of packets allowed in a single burst.
Accepted values are 1 to 2048. For Fast Ethernet ports, set this
value lower than 1024 (output buffer capacity). Lower this
value if the port has overflow problems.
Port PACE Priority Determines if the port detects 3Com’s proprietary PACE format
as packets pass through the port. PACE allows a packet’s priority
(higher priority packets move through the switch before lower
priority packets) to be set at the adapter.
