port you need to configure.
RCC Traffic
Descriptors
Allows you to configure the TD values for PNNI routing control
channels (RCCs). The RCC is a virtual channel connection (VCC)
used between neighboring nodes for the exchange of PNNI routing
protocol messages.
•
Override Default check box (forward) - Select the checkbox to
specify the forward TD for PNNI RCCs.
•
Forward - To configure the forward traffic descriptor for PNNI
routing control channels (RCCs), select the button to the right of
the field. Then choose a TD from the Select Traffic Descriptor
dialog box. (The Override Default check box above the Forward
field must be checked.)
•
Override Default check box (reverse) - Select the checkbox to
specify the reverse traffic descriptor for PNNI RCCs.
•

Static Delay
µ
Sec
(0-16777215)
Static delay for PNNI links in a path is summed to determine the
end-to-end delay of the path. Higher values represent slower links.
The valid range for this field is zero (0) to 167777214
µ
sec. Default
values (in
µ
secs) are:
DS1 – 522 DS3 – 42 OC-3c/STM-1 – 22
E1 – 370 E3 – 41 OC-12c/STM-4 – 10
Note: Changing the value for this attribute does not admin down the
logical port.

Note – For information about configuring Virtual NNI logical ports, see
. Virtual logical ports allow you to configure more than one
logical port on the same physical port. Each logical port that you configure uses a
portion of the total physical port bandwidth.
