Virtual Circuit Statistics

Without the -L option (that is, by default), vcstat displays statistics for all currently active virtual circuits, rather than for links. For example:

hostname% /opt/SUNWconn/bin/vcstat -i10
Tue Sep 18 16:24:23 1990
   If LCN    State Substate Sent Recv Remote address MAC address
O 1 0x200 Data 0/0/0/0 130 130 129.144.133.2
O 1 0x201 Data 0/0/0/0 679 5180 10002244
I 2 0x202 Data 0/0/0/0 501 641 20009988       08:00:20:07:11:a1,0e 

The fields and headings in the above example display are explained as follows:

Column 1 (no heading)

In the first column you see either O, for an outgoing call; I, for an incoming call; or P, for a permanent virtual circuit.

If

Identifies the link over which the call was made. Corresponds to the value of the Link Number parameter in the Link Editor window in x25tool.

State

Displays Data when the call is in the data transfer phase of the connection.

Substate

Displays four toggles (1 is true, 0 false). From left to right these are:

• Sent Receive Not Ready

• Sent Interrupt

• Received Interrupt

• Received Receive Not Ready

Sent and Recv

Displays the number of frames sent and received since the last reboot. (These counts are not reset if you stop and restart your link.)

Remote Address

This field displays the following types of addresses:

• IP addresses for virtual circuits used for IP connections

• AEFs. This type of address is accompanied by a string, osi, partial-osi, or non-osi, indicating the type of AEF.

• X.121 addresses

To display a name or partial name from the xhosts table, use the --s option.

MAC Address

An LSAP address is present for virtual circuits running over LLC2.
