Configuring Overflow Queuing on Frame Relay to Frame Relay PVCs

To configure overflow queuing on a Frame Relay transit PVC, perform the following steps, beginning in
global configuration mode:
Command
Step 1
Switch(config)# interface serial
card/subcard/port:cgn
Switch(config-if)#
Step 2
Switch(config-if)# frame-relay pvc dlci
[accept-overflow {enable | disable | inherit}]
[upc {pass | tag-drop}] [rx-cttr index] [tx-cttr
index] interface serial card/subcard/port:cgn dlci
dlci [accept-overflow {enable | disable |
inherit}] [upc {pass | tag-drop}] [rx-cttr index]
[tx-cttr index]
Examples
The following example shows how to enable overflow queuing on a Frame Relay PVC cross connected
between serial interface 11/1/0:9, DLCI = 200 and serial interface 3/0/0:1, DLCI = 200:
Switch(config)# interface serial11/1/0:9
Switch(config-if)# frame-relay pvc 200 accept-overflow enable interface serial 3/0/0:1 200
Default overflow queuing configuration (for example, inherit from interface) is applied at the destination

end.
The following example shows how to enable overflow queuing on the source Frame Relay PVC cross
connected between serial interface 11/1/0:9, DLCI = 201 and serial interface 3/0/0:1, DLCI = 201,
where the destination end has overflow queuing disabled:
Switch(config)# interface serial11/1/0:9
Switch(config-if)# frame-relay pvc 201 accept-overflow enable interface serial 3/0/0:1 201
accept-overflow disable
The following example shows how to enable overflow queuing on an existing PVC connection at serial
interface 11/1/0:9, DLCI = 100:
Switch(config)# interface serial11/1/0:9
Switch(config-if)# frame-relay pvc 100 accept-overflow enable
The destination end has overflow queuing disabled.
