Chapter 3 1-Port OC-12 ATM Line Card Configuration
This command is supported only for AAL5+SNAP encapsulation (the default) when Inverse ARP is
Note
enabled. Use the encapsulation command to configure AAL5+SNAP encapsulation and the protocol
command to enable Inverse ARP.
The following example shows how to specify an Inverse ARP frequency of 40 minutes on an ATM PVC:
Router(config)# interface atm 5/0/0
Router(config-if)# pvc 0/105
Router(config-if-atm-vc)# inarp 40
Attaching an ATM VC Class to a PVC
To attach an ATM VC class to a PVC, use the class-vc command.
class-vc name
Where:
•
The following example shows how to assign an ATM VC class named boston to an ATM PVC:
Router(config)# interface atm 5/0/0.4
Router(config-subif)# pvc 2/100
Router(config-if-atm-vc)# class-vc boston
Configuring VBR-NRT
To configure the variable bit rate-nonreal time (VBR-NRT) traffic management type and specify output
peak cell rate, output sustainable cell rate, and output maximum burst cell size for an ATM PVC or VC
class, use the vbr-nrt command. Use vbr-nrt in interface-ATM-VC configuration mode or VC-class
configuration mode.
vbr-nrt peak_cell_rate sustainable_cell_rate maximum_burst_size
no vbr-nrt peak_cell_rate sustainable_cell_rate maximum_burst_size
Where:
•
•
•
The default class of service is unspecified bit rate (UBR) running at the maximum line rate of the
physical interface.
Use the no form of this command to remove the VBR-NRT parameters and return the PVC to its default
of unspecified bit rate (UBR).
You can create up to 254 VBR-NRT PVCs on an 1-Port OC-12 ATM line card.
The following example shows how to configure the VBR-NRT traffic parameters on an ATM PVC:
Router(config)# interface atm 5/0/0
Router(config-if)# pvc 0/105
Router(config-if-atm-vc)# vbr-nrt 50000 20000 200
OL-8834-04
name is the name of the class created with the global configuration class-vc atm command.
peak is the peak cell rate (PCR) from 84 Kbps to 299,520 Kbps and 599,040 Kbps.The PCR must
be at least equal to the sustainable cell rate (SCR)
sustainable is the sustainable cell rate (SCR) from 84 Kbps to 299,520 Kbps and 599,040 Kbps.
maximum is a number from 1 to 256 that represents Maximum Burst Size (MBS) in cells
