Chapter 4 Configuring Devices
Configuring the Service Engine
Step 1 Choose Devices > Devices > General Settings > Network > External IP. The External IP Settings page
is displayed.
Step 2 Check the Enable check box.
Step 3 In the External IP Address fields (1–8), enter up to eight IP addresses.
Step 4 Click Submit to save the settings.
Configuring Port Channel and Load Balancing Settings
For information about configuring port channels using the CLI, see the “Redundant Dedicated
Management Ports” section on page E-1.
To configure load balancing on port channels, do the following:
Step 1 Choose Devices > Devices > General Settings > Network > Port Channel Settings. The Port Channel
Settings page is displayed.
Step 2 From the Load Balancing Method drop-down list, choose one of the following load balancing methods:
• dst-ip—Destination IP address
• dst-mac—Destination MAC address
• round robin—Each interface in the channel group
Round robin allows traffic to be distributed evenly among all interfaces in the channel group. The other
balancing options give you the flexibility to choose specific interfaces (by IP address or MAC address)
when sending an Ethernet frame.
Step 3 Click Submit to save the settings.
Configuring TCP Settings
Adjusting TCP parameters for better performance is often overlooked when configuring content caching.
For data transactions and queries between client and servers, the size of windows and buffers is
important, and fine-tuning the TCP stack parameters therefore becomes the key to maximizing cache
performance.
Note Because of the complexities involved in TCP parameters, care is advised in tuning these parameters. In
nearly all environments, the default TCP settings are adequate. Fine-tuning of TCP settings is for
network administrators with adequate experience and full understanding of TCP operation details.
Caution The TCP memory limit settings allow you to control the amount of memory that can be used by the TCP
subsystem send and receive buffers. The default values are device-dependent and have been chosen after
extensive testing. They should not be changed under normal conditions. Increasing these values can
result in the TCP subsystem using more memory, which might render the system unresponsive.
Decreasing these values can result in increased response times and lower performance.
To configure TCP settings, do the following:
