INTRODUCTION

This RLI is a step towards subscriber oriented JUNOS model.

Traditionally

the QoS configs are defined in different hierarchies of the JUNOS config
viewing the QoS config parameters needs the user to
execute a sequence of multiple JUNOS commands corresponding to the different hierarchies.

In the subscriber model

typically a customer/subscriber is represented by a logical-interface
it is desirable to :
- have JUNOS configs for the logical interface grouped together in a single hierarchy
- have a single command that allows viewing parameters specific to a customer.

This RLI, as an initial step

providing a unified operational command that
displays all QoS parameters and counters/statistics
for a specific physical or logical interface.
a requirement from BT for:
- easy verification & debuggability of CoS features
- our competitors provide something like this.
Ref [1] provides more details about the bigger picture in terms of QoS container and the longer term goals.

Existing QoS display commands

At the moment
getting QoS specific details for an interface ge-x/y/z.0
involves running the following set of commands-

(provided by ifinfo)

1. show interface ge-x/y/z.0 extensive
2. show interface queue ge-x/y/z.0
   show interface filters ge-x/y/z.0
   show interface policers ge-x/y/z.0

(provided by dfwinfo)
The above commands display details about

the multi-field classifiers

the policers(single rate/two-rate discard/two/three-color colorblind/color-aware)
Based on the filters/policers attached to the interface from output of (1), display the counters-
```
3.  show firewall filter <filter-name>
4.  show policer <policer-name>
```

(provided by cosd)

This prints out all the different constructs attached to the interface.
```
5.  show class-of-service interface ge-x/y/z.0
```

Based on the above output, get more details about each construct attached-

7.  show class-of-service classifier <classifier-name>          <1>
8.  show class-of-service translation-table <trans-table-name>  <1>
9.  show class-of-service forwarding-class <fc-q-map>
10. show class-of-service traffic-control-profile <tcp-name>

for different families

(provided by cosd)

Based on

the tc-profile in (10) or
a directly attached sched-map in (5)

11. show class-of-service scheduler-map <smap-name>
    [ingress & egress schedulers. chassis scheduler and pic scheduler for queuing pic]

Based on different schedulers listed in the sched-maps [from (11)] [for each queue]
```
12. show class-of-service scheduler <sched-name>
```

Based on the drop-profiles listed in (12) above,

13. show class-of-service drop-profile <dp-name> [from (12)] [for each PLP]
14. show class-of-service rewrite-rule <rw-name> [From (5)] [for each family]
15. show class-of-service fragmentation-map <fragmap-name> [from (5)]

existing "show class-of-service interface" command

show class-of-service interface <intf-name>

Presently, when the argument is an IFD:
- class-of-service objects attached to the IFD are printed in brief,
- followed by the class-of-service objects for all the IFLs on the IFD.
When the argument is an IFL:
- only the cos information for IFL is printed.

Existing output of the command:
- "show class-of-service interface <IFD>" :
  - cos info for IFD
  - cos info for IFLs
- "show class-of-service interface <IFL>" :
  - cos info for IFL
The argument IFD, IFL or wildcard string given to the command is passed directly to the daemon which does the required expansion(e.g in case of wildcard).

This RLI does not plan to change the above behavior of the existing command.

Example:existing output when the argument is an IFD:

Proposed commands

This RLI plans to introduce new options to the following existing command to print out the QoS specific details also.

    "show class-of-service interface"

This RLI will keep the existing output as before but introduce a set of new options to the command
a single operational command will combine the outputs of the previous commands in different ways depending on the qualifier.

The new options are-

    cli> show class-of-service interface <intf-name> [ detail | comprehensive ]

show class-of-service interface <intf-name> detail

the display shall provide the class-of-service information by combining the outputs of:

 show interface <intf-name> brief
 show interface filters <intf-name>
 show interface policers <intf-name>
 show class-of-service interface <intf-name>

This option allows users to view the quality-of-service information by a single command for:
- an IFD
- all the IFLs on the IFD
The argument given to the command would now be first passed to ifinfo.
ifinfo shall
- provide the expanded list of names (a list of matching IFD or IFL names)
- for each item in the list, interface, firewall and cos information shall be printed.

the cosd will not do the wildcard expansion anymore
- ifinfo shall do it( ifinfo and cos both use fnmatch for matching).
If <intf-name> is a physical interface (an ifd):
- the QoS information shall be printed for this ifd as well as for the logical interfaces (ifls) on the ifd;
- the above commands shall be executed for the ifd, then each command shall be executed for the IFLs one by one.
If <intf-name> is logical interface (an ifl), the QoS information shall be printed for this ifl only.

Output of the command with detail option:

"show class-of-service interface <IFD> detail" :
- brief interface info for IFD
- cos info for IFD
- brief interface info for IFL
- cos info for IFL
- filters/policers for IFL
"show class-of-service interface <IFL> detail" :
- brief interface info for IFL
- filters/policers for IFL
- cos info for IFL

This option shows the configured QoS parameters without expanding them.
so it :
- doesn’t display extensive queue stats or
- doesn’t display the filter counters or
- doesn’t expand the different CoS constructs like schedulers etc.

An example output (when the argument is IFD) is given below

example of "show class-of-service interface <intf-name> detail" command

For example: if ge-0/3/0 has two IFLs:

ge-0/3/0.0 and
ge-0/3/0.1:

"show class-of-service interface ge-0/3/0 detail" shall give the following output:

show class-of-service interface <intf-name> comprehensive

The "comprehensive" option will

combine the output of all the QoS commands in section [2]
print the info for the IFD as well as all IFLs under that IFD.

pros

conveniently view the configured constructs comprehensively coupled with the physical or logical interface level where they hold significance.
useful specifically for the case where:
- the IFD has either one or a few IFLs under it and/or
- no per-unit scheduling
some constructs like scheduler-map would be attached to the IFD and
stuff like classifiers & rewrite rules are attached to the IFL.

cons

with a scaled scenario, the output of this command might become quite unmanageable when invoked on an IFD.

CAVEATS

This RLI does not try to add any new output that is not available through other existing commands. For e.g.
- there might be stuff that might be missing like displaying q-pic-large-buffer or
- some counters that are present in the h/w but not available in any RE cli or
- stuff that doesn’t work today like queue counters for logical/tunnel interfaces or
- desirable stuff that the h/w doesn’t support like counters for BA-classification/rewrites

This RLI provides only an operational command combining only QoS related parameters.
It does not print out any other interface specific info that might need to be pulled out from daemons, say, rpd.
No support for:
- interface-set/routing-instance stats or
- any other thing that doesn’t show up as an interface for the first cut.
- Same for ATM-cos, services cos, CoS-Based Forwarding.
- This might be done in a best-effort mode if time permits.
- The RLI doesn’t try to re-format the output into more readable forms
  - say for instance:by combining output from multiple commands into a single table.

The existing "show class-of-service" commands display the configured rather than the actually applied cos parameters in some cases
- like when a wildcard is used to apply a config on pics but all of the pics don’t support it.
- Since the RLI implementation reuses the functionality provided by the existing class-of-service commands, it would also behave in the same way.
Support for range match in interface argument is not included.

While displaying the qos information there are certain unavoidable repetitions
- e.g:
  - same scheduler attached to different scheduler maps gets printed more than once,
  - drop profiles get repeated.
- Logic for avoiding repetition in this case and elsewhere would add to undue complexity in implementation and maybe undermine the actual customer requirement of visualizing all config constructs at one place, so it hasn’t been taken up.
