Chapter3 Equipment and Resource Provisioning addport
addportAdd Port—add a logical port (to the VSI slave).
A logical port is associated with a p hy si cal line. For a UNI or NNI, a line ca n su p po r t o ne lo g ica l p or t .
For a virtual NNI (VNNI), a line can support multiple logical ports.
The range of logical port numbers is 1–60 for the AXSM regardless of the interface type (UNI, NNI, or
VNNI). For example, if a card supports 4 lines and all lines support UNI, the card can have 4 logical
ports whether their numbers ar e 1–4, 1 1–14, 57–60, and so on.
You can only execute addport, on a currently active line. See upln .
Note The maximum number of l ogical ports for the e ntire node is 99. Thi s va lu e is imposed by the
PXM45/A.
Note If your are going to use card statistics, you must execute cnf cdstat before you add any logical ports
using addport. You cannot configure card statistics once you have any logical ports added.
The information you specify with addport consists of the:
•Logical port number
•Line number and bay number
•Guaranteed rate and the maximum rate—currently the same for all interface types
•Service class template ID f o r th e l og ic al interface
•Type of interface (UNI, NNI, or VNNI)
•VPI for all connections on the port if the interface type is VNNI
The node supports a template approach to specifying paramete rs for large numbers of connection s. (You
can modify an individual connection as needed using cnfcon.) The name of such a template is Service
Class Template (SCT). The targets of template application are the logical ports on the one hand and the
card itself on the other. The addport command lets you specify an SCT for a port, and cnfcdsc t lets you
specify an SCT for the card. You can specify th e sa m e o r d iffer ent S C T n u m be r fo r ei th er t he port or
card-level, but you definitely need to s pe cif y an SC T f o r eac h car d an d po r t. The sy s te m au to ma tic ally
assigns a card-level SCT to a card or a por t-level SC T o f t he sam e n umb er t o a p o rt. ( For exam pl e, if
you specify SCT 2 for a port, the system does not assign card-level SCT 2 to that port.)
Cisco Systems provi des SCT numbers 2 an d 3. SCT 2 contains p olicing parameters, bu t SCT 3 does not.
You should specify SCT 2 or 3 or create new templates by modifying SCT 2 or 3 in the Cisco WAN
Manager application and saving t hem with different SCT numbers. To see the a ctual values in an SCT,
use dspportsct for a port SCT or dspcdsct for a card-level SCT. To see a list of SCT files on the disk,
execute cd to get to the SCT direc to ry, then execut e ls to fi nd the directory name d “AXSM.”
Until you specify an SCT, the AXSM has a d efa ul t S CT of 0 . T he system uses SCT ID = 0 when:
•The AXSM is power ed -up for the first ti me.
•The card’s database is rebuilt .
•The card is rebooted and the user-specified SCT file for a particular port is corrupt or missing. In
this situation, the default ap plies to only the affected po r t.
