Monitor Xpress Tunnels

The Xpress tab provides a convenient way to monitor your enhanced Xpress tunnels. It lists all the enhanced tunnels that have been formed with your PacketShaper and indicates configuration information for each tunnel: name, functionality (compression, acceleration, packing), the IP address of the Xpress partner, and whether it's static or dynamic. In addition, the Xpress tab displays Inbound and Outbound statistics for each tunnel: utilization before and after compression/decompression, percentage of bytes saved due to compression, and rate of accelerated traffic. If there is a problem with the tunnel, a warning icon will appear next to the tunnel name.

The Xpress tab gives per-tunnel statistics. If you would like a report on how compression or acceleration is performing overall on your link, a Compression Summary report and an Acceleration Summary report are available.

In addition to monitoring enhanced tunnels, the Xpress tab allows you to:

configure your global tunnel settings (such as firewall or DiffServ support)
define the Xpress-IP addresses of each device on your unit
delete tunnels
create static tunnels
customize settings of static tunnels
convert dynamic tunnels to static

Monitoring Legacy Tunnels

Since the Xpress tab displays information about enhanced tunnels only, you will need to use the command-line interface to monitor legacy tunnels, using the setup compression show command. When you are in legacy mode, you can use the Xpress tab to enable compression, change the tunnel mode, and define the Xpress-IP addresses of each device on your unit.

Monitoring Enhanced Xpress Tunnels

The Xpress Tunnels Overview displays the following information for each enhanced tunnel. show screen


Field	Description
Tunnel Name	Identifying name of the Xpress tunnel. Static tunnels have the descriptive names assigned to them when they were manually created. Dynamic tunnel names are in the form of <xpress-IP>:<device> where <xpress-IP> is the Xpress-IP address of the tunnel partner and <device> is main or a LEM (such as upper or lower). Example: 172.21.19.10:main. If the tunnel name already exists, an ID will be appended so that each tunnel has a unique name. Example: 172.21.19.10:main:1 Clicking the tunnel name displays the Edit Tunnel screen where you can customize settings of static tunnels or convert a dynamic tunnel to static. If there is a problem with the tunnel, a warning icon will appear next to the tunnel name. Placing the mouse pointer on the icon displays a flyover describing the tunnel state. See Tunnel States for descriptions. If the name is italicized, the tunnel has customized settings that are different from the global defaults.
Features	Xpress uses tunnels to transport compressed data, packed data, and/or accelerated data. The Features column can display one or more of the following letters to indicate the tunnel functionality: A if acceleration is enabled globally and the tunnel is set to use the global setting for acceleration (S) for a SkyX tunnel C if compression is enabled globally and the tunnel is set to use the global setting for compression P if packing is enabled globally and the tunnel is set to use the global setting for packing
Device	Name of the device on which the Xpress tunnel was formed: main — built-in interface upper — upper LAN Expansion Module (LEM) lower — lower LEM right — right LEM left — left LEM Note: The Device column appears only if the unit has LEMs installed.
Partner IP	Xpress-IP address of the tunnel partner or IP address of the SkyX device
Type	Indicates whether the tunnel was manually created (static) or automatically discovered (dynamic)
Outbound Pre-Comp.	Average rate over the last minute of outbound traffic before compression has been applied
Outbound Post-Comp.	Average rate over the last minute of outbound traffic after compression has been applied
Outbound % Saved	Percentage of bytes saved in the outbound direction, due to compression
Outbound Acc.	Average rate over the last minute of accelerated outbound traffic
Inbound Decomp.	Average rate over the last minute of inbound compressed traffic after decompression
Inbound Comp.	Average rate over the last minute of inbound compressed traffic before decompression
Inbound % Saved	Percentage of bytes saved in the inbound direction, due to compression
Inbound Accel.	Average rate over the last minute of accelerated inbound traffic
