Configure Ports Or Domains - Viavi Xgig User Manual

Chapter 4, Xgig TraceControl Capture Configuration

Configure Ports or Domains

You must configure all ports in a domain before starting a capture for the domain. If you do not set
the configuration for an analyzer blade, it inherits the default configuration values.
All ports in a domain are divided into state machines. For SAS/SATA, each link is a state machine.
For FC and GE ports, each port pair is a state machine. You can add a link for FC or GE ports. For
SAS/SATA, all ports in a link must reside on the same blade. For FC and GE, ports in a link may
reside on multiple blades within the same chassis. All ports in a state machine transition in sync.
See "General Settings" on page 93
You can apply the configuration of the current state machine to all state machines for that protocol.
If you have a domain with different port types, you must configure ports for each protocol
separately. See
domain with different port types.
The configuration is loaded to the hardware when a capture is started or when the

• Size Options: Number of Segments, Trace Size, Frame Length, Post Trigger Fill
Set the number of buffer segments, the trace size (per segment), the maximum number of
bytes in a frame/packet to capture, and the position of the trigger point within the capture
buffer. The

segmentation.
• Signal Regeneration
The signal can be passed through, or the signal can be boosted and digitally retimed. The
signal attenuation is no more than 4dB for analog passthrough.
• Link Speed
You must set/check the link speed for each port. Auto speed negotiation options are available
for SAS/SATA and for 16G FC ports of the Xgig1000 chassis.
Important: If your network requires you to change link speeds, you should verify that the
link speed is correct even if you have loaded a configuration file.
• Transceiver Options
For 8G blades, select the transceiver options, either

Fibre Channel over Ethernet (FCoE) is the proposed mapping of Fibre Channel over selected
full duplex IEEE 802.3 networks.
