Chapter 3
Configuring Bypass Switches Using the CLI
This chapter describes how to use the CLI to modify the configuration of the bypass switches in the iBypass HD.
In this chapter, you will learn to:
• Configure iBypass HD system options
• Change the system prompt and restart the system
• Configure segment (bypass switch) options
• Customize Heartbeat packets
• Use bypass switch pairs in high availability (HA) modes
Note that different commands affect different levels of the hardware:
• System level commands such as system restart affect the entire system, including all DBMs
• DBM level commands such as module set ha_mode (to set the high-availability mode) affect both switches in
a DBM module
• Segment level commands such as segment set target a single segment (a single switch) within a DBM module
• Port level commands such as s such as port set affect all four ports in a segment simultaneously
For a complete listing of commands in the CLI, see Appendix B.
Syntax
The iBypass HD modules, segments, and ports are specified as follows:
• The four Dual Bypass Modules (DBMs) are numbered 1, 2, 3, 4 from left to right across the chassis; each DBM
has two bypass switches for connection to two network segments
• The eight segments are numbered 1, 2, ... 8 from left to right across the chassis; segments 1 and 2 are in Dual
Bypass Module (DBM) 1, 3 and 4 are in DBM 2, 5 and 6 are in DBM 3, and 7 and 8 are in DBM 4; odd-numbered
segments are in the top row of ports, and even-numbered segments are in the bottom row
• Thjere are currently no commands that affect individual ports. All four ports in a segment always have the same
settings, so a segment number specifies all four ports in the segment
Most commands accept lists. In lists, items are separated by commas with no intervening spaces. A dash can be used to
specify a range. For example seg=1-4,7 specifies five segments.
Restart the System
To restart the system, type system restart. The entire system is reset to its default state and then the saved (running)
configuration is reloaded. Use the system restart command cautiously because the network traffic is disrupted for a
short period.
