PVC Dialog Box—QoS Tab
Use the QoS tab of the PVC dialog box to configure the ATM traffic shaping and other quality-of-service
settings of the PVC, including:
•The limit on packets placed on transmission rings.
•The QoS service.
•Whether random detection is enabled.
These settings regulate the flow of traffic over the PVC by queuing traffic that exceeds the defined
allowable bit rates.
Protocol Applies only when aal5mux is the defined encapsulation type.
The protocol carried by the MUX-encapsulated PVC:
•frame-relay—Frame-Relay-ATM Network Interworking (FRF.5)
on the Cisco MC3810.
•fr-atm-srv—Frame-Relay-ATM Service Interworking (FRF.8) on
the Cisco MC3810.
•ip—IP protocol.
•ppp—IETF-compliant PPP over ATM. You must specify a virtual
template when using this protocol type.
•voice—Voice over ATM.
Additional settings
Enable ILMI When selected, enables ILMI management on this PVC.
When deselected, ILMI management on this PVC is disabled.
Inverse ARP When selected, the Inverse Address Resolution Protocol (Inverse ARP)
is enabled on the PVC.
When deselected, Inverse ARP is disabled. This is the default.
Inverse ARP is used to learn the Layer 3 addresses at the remote ends
of established connections. These addresses must be learned before the
virtual circuit can be used.
Note Use the Protocol tab to define static mappings of IP addresses
instead of dynamically learning the addresses using Inverse
ARP. See PVC Dialog Box—Protocol Tab, page 59-63.
PPPoE Max Sessions The maximum number of PPP over Ethernet sessions that are permitted
on the PVC.
VPN Service Name The static domain name to use on this PVC. The maximum length is
128 characters.
Use this option when you want PPP over ATM (PPPoA) sessions in the
PVC to be forwarded according to the domain name supplied, without
starting PPP.
