After verifying that a call has been established, scan the log to ensure
that the call (and switched virtual circuit) is still active (has not been
cleared). Cleared calls are indicated by an event log entry that takes the
following format:
clr: cct_name.ip_addr.#(C=nn)(D=nn)
where:
cct_name is the name of the X.25 DDN or PDN circuit.
ip_addr is the dotted-decimal IP address of the remote device.
# is the logical connection number.
(C=nn) is the encoded clearing cause.
(D=nn) is encoded diagnostic information.
To display all virtual circuit variables for an established DDN or PDN
virtual circuit, enter the following at the NCL prompt:
x25.cct_name.ipaddr.#.*
where:
x25 is the X.25 managed object
cct_name.ip_addr.# is taken from the event log.
* is the wildcard character.
To display a single virtual circuit variable for an established DDN or
PDN virtual circuit, enter the following at the NCL prompt:
x25.cct.ip_addr.#.code
where:
x25 is the X.25 managed object.
cct_name.ip_addr.# is taken from the event log.
code is the pathname code for the variable.
See the “X.25 Event Messages” in chapter 3.
