I am setting up my 1st frame relay connection and am going through the 7206 config looking at the HSSI configs to get an idea of how to set up the new connection. On almost every frame connection Class Data appears i.e.
interface Hssi6/0.3 point-to-point
description frame connection
bandwidth 128
ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx
ip mtu 1500
frame-relay interface-dlci xx
class DATA128
THe class data number always matches the bandwidth number. THis does not appear on ALL the frame connections but most of them. When I go to configure the interface I do not see Class as an availible command.
What does this Class DATA do and where do I configure for each interface?

DATA128 refers to a class-map as follow:
interface serial 0.1 point-to-point
frame-relay interface-dlci 100
class slow_vcs
map-class frame-relay slow_vcs
frame-relay cir out 9600
They probably kept the name tag the same as the bandwidth for reference.
For more information, refer to the following link:

I wanted to look at all the current map classes so I did a:
7206_2#sh class-ma
Class Map match-all voice-signaling (id 1)
Match access-group 103
Class Map match-any class-default (id 0)
Match any
Class Map match-all video-traffic (id 2)
Match access-group 105
Class Map match-all voice-traffic (id 3)
Match access-group 102
Class Map match-all sap-data (id 4)
Match access-group 104
This did not show me any of the classes that are configured for the HSSI i.e. class DATA128, class DATA256, class DATA384, class DATA896
I think I am getting more confused.

Sorry for the confusion. I meant map-class and not class-map.
You should look at your configuration to see if a map-class is defined for each one of these names. It could look something like this:
map-class frame-relay DATA128
frame-relay cir 128000
map-class frame-relay DATA256
frame-relay cir 256000
map-class frame-relay DATA384
frame-relay cir 384000
map-class frame-relay DATA896
frame-relay cir 896000
Hope this helps,

Ah, I found them. There are a bunch. It looks like one for every line speed fron 64k on up to 1024.
map-class frame-relay DATA256
frame-relay cir 256000
frame-relay bc 2560
frame-relay be 0
frame-relay mincir 256000
frame-relay adaptive-shaping becn
service-policy output DATA-POLICY
!
map-class frame-relay DATA384
frame-relay cir 384000
frame-relay bc 3840
frame-relay be 0
frame-relay mincir 384000
frame-relay adaptive-shaping becn
service-policy output DATA-POLICY

So now that I found these map-class in my config. I went to the interface config mode and did a ? to get a list of availible commands. I see that there is a map-group command. In standard config mode I see there is a map-class and and map-list command. Which config mode should I be in to assign the map class to my HSSI interface and what commands would I use to assign it to the HSSI?
11-29-2004 06:42 AM
frame-relay interface-dlci xx
class DATA128
Hope this helps,

Cool, One last questions... When I do a "no frame-relay interface-dlci xx" to remove the existing one will it break the connection? I have a few active connections that are not configured correclty and I do not want to bring them down if I do a "no" command.
