8. Complete the fields as described in Table 7-7.
Table 7-7. Add Logical Port: PNNI Tab Fields
Field Action/Description
Constant bit
rate (CBR)
Indicates the administrative weight to assign to the CBR QoS
category for the network interface associated with the logical port.
Enter a value between one and 16,777,215, or accept the default
value (5040).
Variable bit rate
real rime
(VBR RT)
Indicates the administrative weight to assign to the VBR-RT QoS
category for the network interface associated with the logical port.
Enter a value between one and 16,777,215, or accept the default
value (5040).
Variable bit rate
non-real time
(VBR NRT)
Indicates the administrative weight to assign to the VBR-NRT QoS
category for the network interface associated with the logical port.
Enter a value between one and 16,777,215, or accept the default
value (5040).
Available bit
rate (ABR)
Indicates the administrative weight to assign to the ABR QoS
category for the network interface associated with the logical port.
Enter a value between one and 16,777,215, or accept the default
value (5040).
Unspecified bit
rate (UBR)
Indicates the administrative weight to assign to the UBR QoS
category for the network interface associated with the logical port.
Enter a value between one and 16,777,215, or accept the default
value (5040).
Aggregation Token Enter a value in this 4-byte field to identify a PNNI outside link that
interconnects two separate peer groups. The default value is zero (0).
The aggregation token determines how this link is aggregated at the
next higher level in the hierarchy. Outside links connecting the same
two peer groups are aggregated if they have the same aggregation
token or if one link has an aggregation token value of zero (0). If the
aggregation tokens of different outside links are not equal and
nonzero, each token will be advertised in a separate horizontal link
PNNI Topology State Element (PTSE) by the associated parent
logical group node (LGN) nodes.
Note: The aggregation token value is important only for outside links
where the neighboring nodes belong in different peer groups.
