RE: Configuring ATM PVCs with UBR vs. ABR posted 01/30/2001

Well, if you are allowed to use sub-interfaces do it, then you do not have
to worry about mapping. If you cannot use sub-interfaces you have to provide
layer 2 to 3 mapping. In new style pvc it is done with "protocol ip 1.1.1.1
broadcast" in pvc mode. I do not think you can do minimum bandwidth with UBR
try ubr+ to set men and max bandwidth. Also you can do it using vc-class and
ubr+. You are correct in saying that you do not need map-groups / map-list,
but you still need mapping.

		Thanks. Someone else just pointed that out as well. I don't
know why I did
		not see that last time I was on an ATM interface, I must
have just been in a
		rush. So it sounds like if I need to specified a minimum and
a maximum for
		UBR, then I need to use the PVC 0/100 method instead of a
map group and
		map-list, is that correct?

		When you configure PVC, let's say you type pvc 0/100 and hit
enter you will
		be in pvc mode. Type ? to see all the available options.

		mdrtgate01(config)#int atm1/0.777 po
		mdrtgate01(config)#int atm1/0.777 point-to-point
		mdrtgate01(config-subif)#pvc 0/100
		mdrtgate01(config-if-atm-vc)#en
		mdrtgate01(config-if-atm-vc)#encapsulation aal
		mdrtgate01(config-if-atm-vc)#encapsulation aal5sn
		mdrtgate01(config-if-atm-vc)#encapsulation aal5snap
		mdrtgate01(config-if-atm-vc)#

				Yan, 

				I didn't see any option for aal5snap under
the pvc 0/1
		method. Maybe I just
				missed it.I'll try again the next chance I
get.

				Thanks for the response.

				When configure new style PVC.
				Int atm 2/0
				Pvc 0/1 then hit enter and it will get you
into pvc mode
		where you can
				specify encapsulation, QoS, and lots more.

						Subject:	Configuring
ATM PVCs with
		UBR vs. ABR

						When configuring ATM PVCs
similar to the
		example in
				Caslow's/Pavlichenko's
						book, 

						Interface ATM 3/0 
						ATM PVC 1 0 99 aal5snap
						IP address 1.1.1.1
255.255.255.0
						Map-group mygroup
						Map-list mygroup
						 Ip address 2.2.2.2 atm-vc 1
aal5snap

						I cannot find an option for
UBR, only ABR.
		After looking
				through the
						archives I see that the
above is an older
		form of mapping a
				PVC. However, I
						cannot find an aal5snap
option when using
		the newer method,

						Interface ATM 3/0
						IP address 1.1.1.1
255.255.255.0
						Pvc-mypvc 0/1......

						Is there a way of specifying
UBR for the
		first example and
				if not, is there
						an option for aal5snap for
the second
		method?
						Also, any helpful links
would be greatly
		appreciated.

						Thanks,

						Jeff
